[0002]

2. Description of the Related Art In recent years, the Internet has spread rapidly,
Business activities on the Internet are attracting attention.

The market is one of the typical existing business forms. That is, the market is a market in which sellers and buyers gather at a common place to form a market price and establish a transaction. If this market could be realized electronically, there would be no need for all the sellers and buyers to meet,
There are also advantages such as quick transactions and equal participation.

Conventionally, with regard to the computerization of such a market, the focus has been on computerizing communication using a telephone, a FAX, or an electronic mail. As a result, it has become possible to participate in the market from a remote location, but it is necessary to intermediate the trading, which is the center of the market, through humans, and the speed and equality that are the advantages of digitization have not been realized. . In addition, it is difficult to reduce market operation costs because human intervention is required.

In order to realize the electronic market, it is necessary to realize the functions of the market electronically. The seller wants to sell as high as possible, and the buyer wants to buy as cheaply as possible. When demand exceeds supply, price rises, and when supply exceeds demand, price decreases. There is a need for a method that automatically finds an optimal combination at a reasonable price among multiple sellers and buyers by reflecting such a function. seller,
Buyers' buying and selling intentions are not fixed, but change depending on various factors such as market prices in the market. As described above, in the electronic market, it is necessary to realize the function according to the market principle by software, but it is difficult to realize such a method.

Further, when electronic markets are simultaneously opened all over the world, it becomes possible to participate in the market from a remote place by using a network, and thus it is possible to participate in these at the same time. If the two markets are not linked, there is a possibility of duplicate buying and selling, making simultaneous participation in multiple markets difficult.

In addition, in the conventional electronic market, it may take time to close the contract after trying to participate in the electronic market, and there is a demand for a more efficient electronic market that takes advantage of the merit of computerization.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

First, the basic configuration of the electronic market system according to the embodiment of the present invention will be described.

(First Embodiment) First, an electronic market system according to a first embodiment of the present invention will be described.

FIG. 1 shows the configuration of the electronic market system according to this embodiment.

The present electronic market system is composed of a central market system 1 at a market opening site and a plurality (arbitrary number) of market client systems 3 at sites of market participants (sale side, purchase side).

It is assumed that the central market system 1 and the individual market client systems 3 can communicate with each other through a predetermined network (not shown) such as the Internet. In the figure, the description of the communication interface portion in each of the central market system 1 and each market client system 3 is omitted. Further, both the central market system 1 and the market client system 3 can be configured using a computer or the like.

The central market system 1 includes an input unit 11 that receives an application from the market client system 3, a purchase application data storage unit 12 that stores purchase application data, a sales application data storage unit 13 that stores sales application data, and these storages. It is provided with a collating unit 14 for collating the purchase application data and the sales application data thus obtained, and a notifying unit 15 for notifying the market client system 3 of the collation result and the like.

The market client system 3 transmits the purchase and sale application information to the market client system 3 and receives a notification of the closing etc. from the market client system 3.

Next, referring to the basic operation procedure of the central market system 1 and the market client system 3 in FIG. 2, the basic functions of the central market system 1 and the electronic market opened by the central market system 1 will be described. And the basic contents of
The basic method of participation of the market client system 3 in the electronic market will be described.

First, in this embodiment, it is assumed that the electronic market is repeatedly opened according to a predetermined time schedule. As an example, a case where the electronic market is opened at a certain time, for example, every hour from 9:00 am to 3:00 pm, can be considered.

The central market system 1 notifies the market client system 3 in advance of market opening information such as market contents and market opening time from the notification unit 15. This notification may be made in response to a request from the market client system 3 or may be made periodically to the market client system 3 registered in advance. Further, it may be advertised to the market client system 3 which is not requested.

Now, the market client system 3 on the selling side or the purchasing side, which is going to participate in the market, creates the purchase and sale application information and transfers it to the central market system 1 (step S4).

That is, by the market opening time (or the application deadline time before that), each market client system 3 sends the trade application information to the central market system 1.

The central market system 1 stores application data in the purchase application data storage unit 12 or the sales application data storage unit 13 based on the application information for buying and selling received from the client system 3 (step S1).

At the market opening time, the collation unit 14 of the central market system 1 collates the application for the sale from the market client system 3 to establish the sale (step S2).

Regarding the collation, generally, it is established when the lowest selling price is equal to or lower than the highest purchasing price. When there are a plurality of such combinations, there are several possible choices, but it is necessary to ensure market equality. For example, there is a method in which a product with a low selling price and a product with a high purchasing price are combined in order, and when the prices are the same, they are randomly selected. There are several possible methods for determining the contracted price. For example, there is a method of taking an intermediate value between the selling price and the purchasing price.

The central market system 1 notifies the market client system 3 on both the selling side and the purchasing side of the fact that the transaction has been completed from the notification section 15 (step S3). If the transaction is not completed, the market client system 3
May be notified, or the fact that the transaction has not been established may be informed that the transaction has not been notified.

Further, the central market system 1 is to the entire market client systems 3 participating in the market,
It is preferable that the notification unit 15 informs the market information regarding the market such as the market status such as the contract price.

Further, it is preferable that the central market system 1 transfers necessary information to the related system in order to cooperate with contract creation, settlement, physical distribution, etc. regarding the products that have been sold and sold.

Now, each market client system 3 participating in the market receives a notification from the central market system 1 (step S5).

By receiving the notification that the transaction has been established, it is possible to know that the purpose of the application has been achieved. Further, since the notification that the transaction has not been established is received and the notification that the transaction has been established has not been sent, it can be known that the purpose of the application has been achieved.

When knowing that the transaction has not been established, each market client system 3 refers to the market information notified from the central market system 1 and refers to the market application information for the next market opening time, for example. Create
Send to the Central Market System 3 to participate in the market. Alternatively, as a result of examination by referring to the market information notified from the central market system 1, for example, it is decided that the next market will not be participated.

Next, the collation processing will be described by giving some concrete examples.

Here, one central market system 1 and 6
It is assumed to be composed of three market client systems 3.

For a certain product, at a certain market opening time, three companies A, B, and C apply for sales, three companies D, E, and F apply for purchase, and the desired sales price is 1 for company A.
It is assumed that the price is 00 yen, the company B is 150 yen, the company C is 180 yen, and the desired purchase price is 80 yen for the company D, 90 yen for the company E, and 100 yen for the company F.

In this case, the lowest selling price is 100 of Company A.
Since the yen and the maximum purchase price are 100 yen for Company F, the transaction is completed between Company A and Company F. of course,
The transaction price is 100 yen.

As a second example, Company A sets the desired selling price to 1
It is assumed that the purchase price is 80 yen for company D, 90 yen for company B, and 120 yen for company F.

In this case, the lowest selling price is 100 of Company A.
The maximum purchase price is JPY 120, and the maximum purchase price is 120 JPY, and the lowest selling price is lower.

Various methods can be considered for determining the transaction price at this time, but a method of taking an appropriate value between 100 yen and 120 yen can be considered. Here, it is assumed that the intermediate value between the two is taken to determine 110 yen.

As a third example, Company A sets the desired selling price to 1
00 yen for company B, 120 yen for company C, 180 yen for company C, and the desired price for purchase is 80 yen for company D, 120 yen for company E, and 130 for company F.
It shall be a circle.

In this case, there are multiple combinations that can be closed. That is, Company A and Company E, Company B and Company E, Company A and Company F
Company, company B and company F can be combined.

Any of these may be selected, but here, Company A with the lowest selling price, Company F with the highest purchasing price, Company B with the second lowest selling price and Company E with the second highest purchasing price are selected. A deal shall be concluded between and. Alternatively, a trade may be established between the company A having the lowest selling price, the company E having the second highest purchasing price, the company B having the second lowest selling price, and the company F having the highest purchasing price.

By the way, in each of the above-mentioned examples, the transaction unit is the same on the selling side and the purchasing side, but as a fourth example, a case where a transaction amount is added will be described.

For example, it is assumed that the transaction application quantity and amount on the selling side are as shown in FIG. 3, while the transaction application quantity and amount on the purchasing side are as shown in FIG.

Also in this case, a plurality of combinations that can be closed are possible as in the case of the third example. For example, as described above, the collation is performed in the order of low selling price and high purchasing price, and the two quantities The smaller one should be the trading quantity.

In this example, a trade is first established between the company A that offers the lowest selling price and the company F who offers the highest purchasing price. The trading price is 115 yen, which is the intermediate value, and the quantity of the company 10 is 10. And the smaller of company 5's 5 is decided. As a result, all the purchase applications for company F have been established, so they are deleted from the purchasing company list (purchase application data storage unit 12), but the sales application for company A has a remaining amount of 5, and the seller list (sales application data storage unit 12). 13) Reduce the quantity and continue the verification.

Next, a transaction is established between Company A and Company E. The transaction price is 110 yen and the quantity is 5. As a result, all the sales applications of the company A have been established, so the company A is deleted from the sales company list.

Next, a transaction is established between Company B and Company E, and the transaction price is 120 yen and the quantity is 5. As a result, all sales applications for company B have been completed, so they are deleted from the list of distributors.
Reduce the number of buyers list and continue matching.

From this point onward, the selling price exceeds the purchasing price, so the transaction cannot be established.

Next, FIG. 5 shows an example of a more detailed operation procedure of the central market system 1 of this embodiment.

In the present embodiment, the market client system 3 creates purchase application data or sales application data as application information for buying and selling for each individual market and sends it to the central market system 1. In this embodiment,
To determine the buying and selling price in the market client system 3, for example, price determination support software based on the market information obtained from the central market system 1 may be used, or the user's judgment may be involved. .

As described above, it is assumed that the electronic market is repeatedly opened at scheduled times.

[0120] The central market system 1 accepts, at any time, an application for trading from the market client 3 to the next electronic market until the next electronic market opening time (step S11) (steps S12, S13).

[0121] When an application for buying or selling the next electronic market is received from the market client 3 (step S13), if the received data is purchase application data (step S1).
4) This is stored in the purchase application data storage unit 12 (step S15), and if the received data is sales application data (step S14), this is stored in the sales application data storage unit 13
(Step S16) and returns to step S11.

When the opening time is reached in step S11 by repeating the above operation, the collating unit 14 performs the collating process (step S17).

Then, the notification unit 15 notifies the market client system of the collation result (step S18).

The notification in step S18 may be made after all the collations in step S17 have been completed, or may be made at that time each time the collation in step S17 is completed.

Then, the data is deleted from the purchase application data storage unit 12 and the sales application data storage unit 13, and the process returns to step S11 to prepare for the next registration and waits for the reception of the application.

As for the market client system 3 that has participated in the market of the time concerned and the transaction has not been established, as described above, the price or the like when participating in the next market is appropriately determined or the participation. If it decides not to participate and participates, the purchase application data or the purchase application data is transmitted to the central market system 1 by the opening time of the next electronic market.

Next, FIG. 6 shows another example of a more detailed operation procedure of the central market system 1 of this embodiment. In the procedure of FIG. 5, the application is accepted until the market opening time, the application is closed at the market opening time, the purchase application data storage unit 12 and the sales application data storage unit 13 are initialized in step S19, and then the next time. The application acceptance is started, but the procedure of FIG. 6 is such that the acceptance start time and the acceptance deadline time of the application are also set in advance. The other points are the same as the procedure of FIG.

First, the central market system 1 notifies the market client system 3 of the market opening information in advance from the notification section 15 as well as the reception start time and the reception deadline.

When the reception start time comes (step S11-1), the central market system 1 accepts an application for buying and selling the electronic market from the market client 3 at any time until the reception deadline (step S11-1). S11-
2, S12, S13). The received application data is stored in the purchase application data storage unit 12 or the sales application data storage unit 13 in the same manner as the procedure of FIG.

Then, at the opening time in step S11-3, collation processing / notification processing is performed.

Then, the data is deleted from the purchase application data storage unit 12 and the sales application data storage unit 13, and the process returns to step S11 in preparation for the next registration, and waits for the next reception start time.

In the following second to ninth embodiments, it is assumed that the above-described configuration is provided as a basic configuration, and the description of the second to ninth embodiments will mainly be made for each implementation. It is assumed that the form is different from the first embodiment or is added to the first embodiment.

(Second Embodiment) Next, a second embodiment of the present invention will be described.

In this embodiment, the market client system 3 sends in advance information such as trading prices at a series of market opening times to the central market system 1 as time series data, and the central market system 1 side transmits the time series data. As long as there is such a request, the purchase application data or the sales application data of the applicable market client system 3 is automatically updated.

FIG. 7 shows the configuration of the electronic market system according to this embodiment. Further, FIG. 8 shows an example of an operation procedure of the central market system of the present embodiment.

As shown in FIG. 7, in the central market system 1 according to this embodiment, in addition to the configuration of the first embodiment, a trading application time series data storage unit 16 and an updating unit 17 are provided.
Have.

The time-series data storage unit 16 stores the trading application time-series data sent from the market client system 3 in advance.

At each time when the market is opened, the updating unit 17 extracts the purchase price or the selling price at the corresponding time from the trade application time series data of each market client system 3 in the time series data storage unit 16. Then, it is set in the purchase application data storage unit 12 or the sales application data storage unit 13.

As a result, the communication between the central market system 1 and the market client system 3 can be reduced, and the operation of gradually lowering the selling price or raising the purchasing price over time is automated. .

Now, the trading application time-series data and the automatic updating of the purchasing application data and the sales application data by the data will be described.

FIG. 9 shows an example of trading application time series data. In the example of FIG. 9, the hourly price of each company is represented in the form of a graph, the horizontal axis represents time, and the vertical axis represents price. The price graph for each opening of the market is created in the form of a table or procedure in each market client system 3 and sent to the central market system 1.

As shown in FIG. 9, generally, the graph on the selling side is in the decreasing direction, and the graph on the purchasing side is in the increasing direction.
By comparing these six graphs at each market opening time, it is possible to determine the success of the sale.

In the case of the example in FIG. 9, the selling side A until 11:00,
The prices of companies B and C are higher than those of companies D, E, and F on the purchasing side, and the transaction cannot be established.

At 12:00, the selling price of Company A and D
The sales prices of company F and company F are the same. Therefore, at this point, a deal is established between Company A and Company D, or Company F. Here, it is assumed that a deal is established between Company A and Company D. After this, the graphs of Company A and Company D are deleted.

The next transaction is concluded between Company C and Company E or Company F at 3 o'clock. Here, it is assumed that it is established between Company F and Company C that offer the highest purchase price and the lowest sale price.

In this way, it is possible to express sales and purchase strategies corresponding to time.

Next, the operation procedure of the central market system 1 of this embodiment will be described with reference to FIG. In addition,
As described above, the electronic market is opened at the scheduled time, but in FIG. 8, the description for the repetition is omitted and only the procedure for one electronic market is shown.

The central market system 1 accepts an application from the market client 3 at any time, and when the trading application time series data is received, it is stored in the trading application time series data storage unit 16.

In the central market system 1, when the opening time comes (or when the set time before the opening time comes), the updating unit 17 prepares for the next electronic market and makes a trade application. Data corresponding to the opening time of the electronic market is read from the series data storage unit 16 (step S21).

Next, if the read data is for the purchasing side (step S22), the updating part 17 stores this in the purchase application data storage part 12 as purchase application data (step S23), and the read data. If is on the sales side (step S22), it is stored in the sales application data storage unit 13 as sales application data (step S22).
24).

The purchase application data and the sales application data transmitted from the market client system are also stored in the purchase application data storage unit 12 and the sales application data storage unit 13.

The above operation is repeated until there is no corresponding data (step S25).

Next, if all the data settings are completed (if the settings are completed before the opening time, the opening time comes), the collating unit 1 as shown in the first embodiment.
The collation process by 4 and the notification process by the notification unit 15 are performed (steps S26 and S27).

In the central market system 1, as post-processing, data is deleted from the purchase application data storage unit 12 and the sales application data storage unit 13, and the sales application time-series data corresponding to the contracted sales application time-series data. Is deleted from the trading application time-series data storage unit 16, and preparations are made for the next market opening.

In the present embodiment, both the application based on the purchase application data and the sales application data and the application based on the trading application time series data are accepted, but all the applications may be accepted based on the trading application time series data. . In this case, when applying only once, purchase application data or sales application data with time information added may be treated as the sales application time-series data.

(Third Embodiment) Next, a third embodiment of the present invention will be described.

In this embodiment, the minimum market price, average price, maximum purchase price, average price, total number of sales applications, and total number of purchase applications are notified from the central market system 1 to each market client system 3 at each time. However, the market client system 3 is provided with a function of automatically determining the selling price or the purchasing price at the next time based on these pieces of information.

FIG. 10 shows the configuration of the electronic market system according to this embodiment. Further, FIG. 11 shows an example of the operation procedure of the market client system according to the present embodiment, and FIG.
An example of the operation procedure of the central market system according to the present embodiment is shown in FIG.

The central market system 1 according to this embodiment is
The configuration is almost the same as that of the first embodiment.

As shown in FIG. 10, the market client system 3 according to this embodiment has a procedure storage unit 31 and an updating unit 32 in addition to the configuration of the first embodiment.

The procedure storage unit 31 stores the procedure for determining the selling price or the purchasing price at the next time.

The updating section 32 activates a preset procedure stored in the procedure storing section 31, and based on the market information sent from the central market system 1, the selling price or the purchase price at the next time. To decide. The application data including the determined price information is sent to the central market system 1 as in the first embodiment.

As a result, the market client system 3 can make an automatic judgment according to the market situation.
Improve automation of market participants' operations.

The automatic price determination function based on the market information will be described.

In the present embodiment, the central market system 1 sends information about the previous market to the market client system 3 before the market opening time. As a result, the market client system 3 can determine the next purchase price or sale price by referring to these pieces of information.

As a concrete example, it is assumed that six companies A to F participate in the market, A and B are on the selling side, and C, D, E, and F are on the purchasing side. At this time, it is assumed that the offer price of each company at the previous market opening time is as shown in FIG. At this point, the lowest selling price is higher than the highest buying price, so the transaction has not been concluded. It is assumed that the central market system 1 informs the market client system 3 of the market information as shown in FIG.

In the present embodiment, each market client system 3 can incorporate a procedure for determining the next application price using these values sent from the central market system 1.

As an example of such a procedure, the procedure of Company A is shown below. (1) If the total number of sales offers is less than the total number of sales offers, the selling price is presented as it is. (2) If the maximum purchase offer price <sales limit price,
I will not show it next time. (3) If the selling price minus the maximum offer price <10, the selling price is reduced by half the difference.

The first condition is that the demand is higher than the supply, and the seller is bullish, and he / she must deal with it without lowering the selling price. The second condition is a case where there is no offer for purchase above the marginal price of sale, and in this case, it is judged that there is no prospect of a transaction, and no offer is offered for the next time. The third condition is when it is judged that the difference between the offered selling price and the highest buying asking price is small,
In this case, it means to lower the selling price and aim to close the transaction.

In this way, the procedure is described in the rule format,
If there are multiple matches, it is possible to set a priority among the rules. The procedure description may be in any format.

As described above, by incorporating the procedure for determining the price to be offered at the next market opening time by using the market information sent from the central market system 1, the market client system 3 responds to the market situation. It becomes possible to judge.

Next, the operation procedure of the electronic market system of this embodiment will be described with reference to FIGS. As described above, the electronic market is opened at a scheduled time, but in FIG. 12, the description for the repetition is omitted and only the procedure for one electronic market is shown.

The market client system 3 on the selling side or the purchasing side who wants to participate in the market creates the purchase and sale application information and transfers it to the central market system 1 (step S31). Then, it waits for a notification from the central market system 1.

On the other hand, the central market system 1 performs processing such as acceptance, storage, collation, and notification of application data as in the first embodiment (step S36). Further, the market information is transmitted (step S37).

By receiving the notification that the transaction has been completed, each market client system 3 participating in the market can know that the purpose of the application has been achieved. Further, since the notification that the transaction has not been established is received and the notification that the transaction has been established has not been sent, it can be known that the purpose of the application has been achieved.

The market client system 3 knows that the transaction has not been established (step S3).
2) The market information transmitted from the central market system 1 is received (step S33), the updating unit 32 activates the procedure, and the selling price or the purchase price at the next time is determined based on the market information (step S34). ). Note that not only the immediately preceding market information but also the history of past market information may be used to generate the next trading application time series data.

If it is decided not to participate in the next market (step S35), the procedure ends.

If the user participates in the next market again (step S35), the process returns to step S31 to transfer the trading application information to the central market system 1 and wait for the notification of the result. When the market client system 3 knows that the transaction has been established (step S32), it ends this procedure. Even in this case, the market information transmitted from the central market system 1 may be received and stored for later reference.

(Fourth Embodiment) Next, a fourth embodiment of the present invention will be described.

In this embodiment, as in the second embodiment, the market client system 3 sends in advance information such as trading prices at a series of market opening times to the central market system 1 as application time series data, The central market system 1 automatically updates the purchase application data or the sales application data for the corresponding market client system 3 as long as there is time series data.
The market client system 3 as in the third embodiment
Generates the next application time series data based on the minimum price, average value, maximum purchase price, average value, total number of sales applications, and total number of purchase applications notified from the central market system 1. The function to do is provided.

FIG. 15 shows the configuration of the electronic market system according to this embodiment. 16 shows an example of the operation procedure of the central market system according to this embodiment, and FIG. 17 shows an example of the operation procedure of the market client system according to this embodiment.

The time-series data storage section 18 stores the trading application time-series data sent from the market client system 3 in advance.

At each time when the market is opened, the updating unit 19 extracts the purchase price or the selling price at the corresponding time from the trade application time series data of each market client system 3 in the time series data storage unit 18, respectively. Then, it is set in the purchase application data storage unit 12 or the sales application data storage unit 13.

As a result, the communication between the central market system 1 and the market client system 3 can be reduced, and the operation of gradually lowering the selling price or raising the purchasing price over time is automated. .

As shown in FIG. 15, the market client system 3 according to the present embodiment has a procedure storage unit 33 and an updating unit 34 in addition to the configuration of the first embodiment.

[0187] The procedure storage unit 33 stores the procedure for determining the next trade application time series data. In addition,
In the third embodiment, the procedure is for determining the next trade application data, but in the case of the present embodiment, the procedure is, for example, to increase the price with respect to time or to determine the time series data. It includes rules for setting or modifying the slope of decrease, rules for setting or modifying how to change the price with the passage of time (shape of time-price curve; see FIG. 9), and the like.

The updating unit 34 activates a preset procedure stored in the procedure storing unit 33, and determines the next trading application time series data based on the market information sent from the central market system 1. . In addition, the determined trading application time series data is sent to the central market system 1 in the same manner as in the first embodiment.

The purchase application data and the sales application data transmitted from the market client system are also stored in the purchase application data storage unit 12 and the sales application data storage unit 13.

The above operation is repeated until there is no corresponding data (step S45).

Next, if all the data settings are completed (if the settings are completed before the opening time, the opening time comes), the matching processing / notification unit 15 by the matching unit 14 is executed.
Notification processing is performed (steps S46 and S47).

In the central market system 1, as post-processing, data is deleted from the purchase application data storage unit 12 and the sales application data storage unit 13, and the sales application time series data corresponding to the contracted sales application time series data. Is deleted from the trading application time-series data storage unit 18, and preparations are made for the next market opening.

The operation procedure of the market client system of this embodiment will be described below with reference to FIG.

The market client system 3 on the selling side or the purchasing side who wants to participate in the market creates the trading application time series data and transfers it to the central market system 1 (step S51). Then, it waits for a notification from the central market system 1 (step S52).

Now, each market client system 3 participating in the market can know that the purpose of the application has been achieved by receiving the notification that the transaction has been established. Further, since the notification that the transaction has not been established is received and the notification that the transaction has been established has not been sent, it can be known that the purpose of the application has been achieved.

The market client system 3 knows that the transaction has not been established (step S5).
3) The market information transmitted from the central market system 1 is received (step S54).

If the trading application time series data previously transmitted to the central market system 1 includes the data for the next time (step S55), the process returns to step S52 to notify the result in the next electronic market. wait.

On the other hand, if the trading application time-series data previously transmitted to the central market system 1 does not include the data for the next time (step S55), the updating unit 34 activates the procedure and notifies the market. Based on the information, the next sales application time series data is generated (step S56). Note that not only the immediately preceding market information but also the history of past market information may be used to generate the next trading application time series data.

If it is decided not to participate in the next market (step S57), the procedure is terminated.

If the user participates in the next market again (step S35), the process returns to step S51 to transfer the trading application time series data to the central market system 1 and wait for the notification of the result.

When the market client system 3 learns that the transaction has been established (step S5).
3) End this procedure. Even in this case, the market information transmitted from the central market system 1 may be received and stored for later reference.

In the present embodiment, the next trading application time series data is generated when the trading application time series data previously transmitted to the central market system 1 does not include data for the next time. However, even if the trading application time series data transmitted to the central market system 1 includes the data for the next time, if the user wants to correct this, the next trading application time series data is generated, This may be re-registered in the central market system 1.

The procedure when the market client system 3 makes an application based on the purchase application data or the sales application data is the same as in the first embodiment.

In the present embodiment, both the application based on the purchase application data and the sales application data and the application based on the trading application time series data are accepted, but all the applications may be accepted based on the trading application time series data. . In this case, when applying only once, purchase application data or sales application data with time information added may be treated as the sales application time-series data.

(Fifth Embodiment) Next, a fifth embodiment of the present invention will be described.

This embodiment is such that the central market system 1 has the same functions as those of the third embodiment.

FIG. 18 shows the configuration of the electronic market system according to this embodiment. Further, FIG. 19 shows an example of the operation procedure of the central market system of the present embodiment.

As shown in FIG. 18, the central market system 1 according to the present embodiment has a trading application data generation procedure storage unit 20 and an updating unit 21 in addition to the configuration of the first embodiment.

The transaction application data generation procedure storage unit 20 is
The transaction application data generation procedure for determining the selling price or the purchasing price at the next time, which is sent in advance from the market client system 3, is stored.

The updating unit 21 determines the selling price or the purchase price at the next time by executing the trading application data generation procedure created by the market participant, and stores the purchasing application data storage unit 12 or the sales application data. Set in section 13.

As a result, it is possible to automatically generate trading application data reflecting the market situation without performing communication between the central market system 1 and the market client system 3 at each market opening time. Also, the operation of gradually lowering the selling price or raising the purchase price over time is automated.

Next, the operation procedure of the central market system 1 of this embodiment will be described with reference to FIG. Note that, as described above, the electronic market is opened at a scheduled time, but in FIG. 19, the description for the repetition is omitted and only the procedure for one electronic market is shown.

The central market system 1 receives an application from the market client 3 at any time, and when it receives the trading application time series data, it stores it in the trading application time series data storage unit 16.

In the central market system 1, when the opening time comes (or the set time before the opening time comes), first, the updating unit 21 enters the market from the trading application data generation procedure storage unit 20. The transaction application data generation procedure created by the person is read (step S61).

Next, the updating unit 21 determines the selling price or the purchasing price at the next time based on the notified market information by executing the trade application data generation procedure, or does not apply for the next time. It is determined (step S62).

If it is decided not to participate in the next market (step S63), nothing is stored in the purchase application data storage section 12 and the sales application data storage section 13.

If the market is to be re-entered (step S63), the updating section 17 stores the purchase application data as purchase application data if the generated data is for the purchase side (step S64). If the generated data is for the sales side (step S64), it is stored in the sales application data storage section 13 as sales application data (step S6).
6).

The purchase application data and the sales application data transmitted from the market client system are also stored in the purchase application data storage unit 12 and the sales application data storage unit 13.

The above operation is repeated until there is no corresponding procedure (step S25).

Next, if all the data settings are completed (if the setting is completed before the opening time, the opening time comes), the matching processing / notification unit 15 by the matching unit 14 is executed.
Notification processing is performed (steps S68, S69).

In the central market system 1, as post-processing, data is deleted from the purchase application data storage unit 12 and the sales application data storage unit 13, and the sales application time-series data corresponding to the contracted data is transferred to the sales application time-series. Data storage unit 16
To prepare for the next market opening. In addition,
Here, it is assumed that the trading application time-series data determined not to be applied is deleted from the trading application time-series data storage unit 16 because there is no possibility of application for the next shift.

On the other hand, the market client system 3 on the selling side or the purchasing side who wants to participate in the market creates the trading application time series data and transfers it to the central market system 1.
Then, it waits for a notification from the central market system 1.

Each market client system 3 participating in the market can know that the purpose of the application has been achieved by receiving the notification that the transaction has been established. Further, since the notification that the transaction has not been established is received and the notification that the transaction has been established has not been sent, it can be known that the purpose of the application has been achieved.

Also in this embodiment, the market information may be transmitted from the central market system 1 to the market client system 3, and the market client system 3 may receive the transmitted market information and store it. .

The market client system 3 adds the information of the valid period to the trading application data generation procedure and transmits it to the central market system 1, and the central market system 1 carries out each trading application data generation procedure only during the valid period. You may make it use this.

The procedure when the market client system 3 makes an application using the purchase application data or the sales application data is the same as in the first embodiment.

In the present embodiment, both the application based on the purchase application data and the sales application data and the application based on the sales application time-series data are accepted, but all the applications may be accepted by the transaction application data generation procedure. . In this case, when applying for only once, it suffices to use the transaction application data generation procedure for generating one-time purchase application data or sales application data.

In the present embodiment as well, as in the fourth embodiment, the market client system 3 is provided with a function of creating a trading application data generation procedure based on the market information notified from the central market system 1. The market client system 3 generates or modifies the trading application data generation procedure by a predetermined procedure based on the market information from the central market system 1, and registers or re-registers it in the central market system 1. Is also good.

As described above, the first embodiment having the basic structure, the second embodiment to the fifth embodiment in which the predetermined function relating to the purchase application data and the sales application data is added to the central market system or the market client system. However, the respective embodiments can be implemented in any combination.

For example, the market client system is provided with all the functions of the first to sixth embodiments, and the market client system uses the purchase application data or the sales application data, the trade application time series data, and the trade application data. An application may be made to the central market system also by the generation procedure.

In the following, an embodiment in the case of realizing duplicate application to a plurality of markets will be described. The sixth below
In the ninth embodiment, in order to make the description easy to understand, a case where the market client system makes an application based on the purchase application data or the sales application data will be described. Of the first to sixth embodiments, It is possible to apply any combination of the above to the sixth to ninth embodiments.

(Sixth Embodiment) Next, a sixth embodiment of the present invention will be described.

FIG. 20 shows the configuration of the electronic market system according to this embodiment. Further, FIG. 21 shows an example of the operation procedure of the central market system according to the present embodiment.

In the present embodiment, in the configuration of the first embodiment, the central market system 1 is provided with the functions of the two systems of the electronic market, and the first system is dedicated to the purchase application data storage unit 12 ₁ . A sales application data storage unit 13 ₁ and a collation unit 14 ₁ are provided, and a purchase application data storage unit 12 ₂ , a sales application data storage unit 13 _2, and a collation unit 14 ₂ are provided exclusively for the second system, and an input unit 11 and The notification unit 15 is shared by both systems.

Further, the central market system 1 according to the present embodiment, in addition to the configuration of the first embodiment, links the electronic market of the first system and the electronic market of the second system,
It has an interlocking procedure storage unit 22 and an interlocking unit 23 .

In this embodiment, it is assumed that the electronic market is opened for a plurality of products by one central market system 1. In other words, the purchaser wants to participate in one of the multiple product markets that is advantageous.
In such a case, the market client system 3 writes the fact that the application information is duplicated in a plurality of markets and sends it to the central market system 1. In the central market system 1 that accepts this, the interlocking unit 23 controls so that the trading does not overlap. The interlocking unit 23 includes both collating units 14 ₁ ,
14 ₂ are from the verification result is input, the interlocking portion 23 if pre duplicate application is registered in the interlocking procedure storage unit 22 as the interlocking procedure, which was performed to change the other trading application data. As a result, it is possible to link the product markets within the market.

Next, the linking process between the commodity markets will be described using a specific example.

In this example, it is assumed that the markets for "apple" and "mandarin orange" are opened at the same time (the apple market is the first line and the orange market is the second line). Here, the buyer can apply to multiple markets at the same time. In addition, if it is established in one of the markets, it will have an interlocking function that cancels in the other markets.

Here, it is assumed that the application status at a certain time in the apple market is as shown in FIG. 22, and the application status at a certain time in the orange market is as shown in FIG.

Here, it is assumed that Company E needs either "apple" or "mandarin orange" and does not need both. If the two markets are independent, in the apple market, a trade between company A, which offers the lowest selling price, and company E, who offers the highest purchasing price, is concluded, and in the mandarin orange market, a deal between company C and E is also established. Company E must purchase it in duplicate. In order to realize the function of simultaneously applying to a plurality of markets while avoiding such duplication, in the case of applying for duplication, the market client system 3 is informed that it is linked to the central market system 1 in advance, and the central market system 1 Then, we will introduce a method to avoid duplication by holding the linked information and changing the application to the other market if one market is established.

Company E informs the central market system 1 at the time of application that the application to the apple market and the application to the mandarin orange market are duplicated in advance. For example, the following procedure is registered in the linked procedure storage unit 22 as the linked procedure. (1) If company E is established in the apple market, cancel application of company E in the orange market. (2) If company E is established in the mandarin orange market, the application of company E in the mandarin orange market is canceled.

Either the apple market or the mandarin orange market may be opened first, but here, the apple market is the first. In the apple market, a deal is established between the company A that offers the lowest selling price and the company E that offers the highest purchasing price.

[0248] The collating unit 1 of the first system of the central market system 1
In 4 ₁ informs the Closing information on interlocking portion 23. The interlocking unit 23 performs matching with the registered interlocking procedure. In this case, since the first rule matching can be established, by deleting data corresponding from the purchase application data storage unit 12 ₂ of the second system to cancel the E's apply in mandarin market. When the mandarin orange market is opened next time, the application for company E has been canceled, so a transaction is established between companies C and G.

As described above, by simultaneously opening a market for a plurality of products, it is possible to increase the convenience of market participants by eliminating competition.

Next, the operation procedure of the central market system 1 of this embodiment will be described with reference to FIG. Although the electronic market is opened at the scheduled time as described above, the description for the repetition is omitted in FIG. 21, and only the procedure for one electronic market is shown.

The central market system 1 receives the application from the client system 3 (step S71).

If the received application is for the first system market, the application data is stored in the purchase application data storage unit 12 ₁
Or stored in the sales application data storage unit 13 ₁ (step S72-1), as long as for the market of the second system,
The application data is stored in the purchase application data storage unit 12 ₂ or the sales application data storage unit 13 ₂ (step S72-
2).

As described above, in the case of an application for duplicate participation, it is stored in both the purchase application data storage units 12 ₁ and 12 ₂ or the sales application data storage units 13 ₁ and 13 _2. Further, the interlocking procedure as described above is registered in the interlocking procedure storage unit 22.

Incidentally, step S72-1, step S7
2-2 is repeatedly performed according to the reception of the application.

In each system, at the market opening time, the collating units 14 ₁ and 14 ₂ collate the application for sale from the market client system 3 to establish the sale (step S73-1 and step S73-2). ).

Then, as described above, the interlocking process is performed as necessary (steps S74-1 and S74).
-2). For example, to cancel the corresponding application of the second system in accordance with overlapping application for the first system that contracts concluded previously inform the establishment information from the collating unit 14 ₁ to the interlocking portion 23, interlocking procedure in interlocking part 23, as described above Decide,
In the second system, the purchase application data storage unit 12 ₂
Alternatively, the corresponding data is deleted from the sales application data storage unit 13 ₂ .

The above procedure is repeated for each system.
It is repeated until the matching is completed (step S75).
-1 and step S75-2).

As described in the first embodiment,
Notification processing is performed as necessary.

On the other hand, the market client system 3 on the selling side or the purchasing side who wants to participate in the market may find that the applications are duplicated in the application.
Notify 1, 1-2. And the central market system 1-
Wait for notification from 1, 1-2.

Each of the market client systems 3 participating in the market can know that the purpose of the application has been achieved by receiving the notification that the transaction has been established. Further, since the notification that the transaction has not been established is received and the notification that the transaction has been established has not been sent, it can be known that the purpose of the application has been achieved.

In the case where only a part of the application quantity is closed as described in the first embodiment,
You may choose not to close only part of the contract, or if you only close part of it, cancel only the part of the contract for the relevant data in the other system market (update the quantity in the data). Alternatively, when only a part of the contract is closed, all the data may be canceled in the markets of other systems.

In this embodiment, the interlocking of two markets has been described, but it is also possible to interlock three or more markets.

(Seventh Embodiment) Next, a seventh embodiment of the present invention will be described.

FIG. 24 shows the configuration of the electronic market system according to the seventh embodiment of the present invention. Further, FIG. 25 shows an example of an operation procedure of the central market system according to the present embodiment.

In the present embodiment, the electronic market system includes two central market systems 1-1 and 1-1 at the market opening site.
1-2 and a plurality of market client systems 3 at the market participants' sites.

In the sixth embodiment, a plurality of markets opened in one central market system 1 are linked, but in the present embodiment, the same mechanism as that of the sixth embodiment is used. This is a system in which a plurality of markets opened in each central market system 1 are linked.

Central market system 1-1 according to the present embodiment
Is a configuration in which the function of the market interlocking procedure is added to the configuration of the first embodiment. The input unit 11-1, the purchase application data storage unit 12-1, the sales application data storage unit 13-1, the collation unit 14- 1, a notification unit 15-1, a market interlocking procedure storage unit 24-1, and a market interlocking unit 25-1.

The central market system 1-2 has the same configuration as the central market system 1-1, and the input unit 11-
2, a purchase application data storage unit 12-2, a sales application data storage unit 13-2, a collation unit 14-2, a notification unit 15-2, a market interlocking procedure storage unit 24-2, a market interlocking unit 25-2 There is.

The configuration / operation of the market client system 3 is the same as that of the sixth embodiment, and the description thereof is omitted in FIG.

In this embodiment, it is assumed that the electronic markets are distributed and opened simultaneously. That is, the purchaser wants to participate in a plurality of distributed markets at the same time and want to make a transaction on the more advantageous side without duplicate trading in any of the markets. In such a case, the market client system 3 enters the fact that the application information is duplicated in a plurality of markets, and the central market system 1-
Send to 1-2. In the distributed central market systems 1-1 and 1-2 that have received this, the collation results are exchanged between them, and control is performed so that trading does not overlap.
The market interlocking unit 25-1, 25-2 receives the collation result sent from the other central market system 1-2, 1-1, and the duplicate application is previously marketed as the market interlocking procedure storage unit 24- If registered in No. 1, 24-2, this is executed to change the trading application data. This makes it possible to link the markets.

Next, the inter-market linkage process will be described using a specific example.

In this example, the central market system # 1 (1-
1) is in Tokyo, the central market system # 2 (1-2) is in Osaka, the Tokyo market and the Osaka market are held alternately, and the contract results are sent to each other.

Here, the application situation in the Tokyo market is shown in FIG.
In addition, it is assumed that the application status in the Osaka market is as shown in FIG. 27.

In this example, Company E makes duplicate purchase applications in both markets. In order to duplicate in advance, for example, the following procedure is registered in the market interlocking procedure storage units 24-1 and 24-2 of both markets. (1) If company E is established in the Tokyo market, cancel application for company E in the Osaka market. (2) If company E is established in the Osaka market, cancel application for company E in the Tokyo market.

The first procedure is stored in the market-linked procedure storage section 24-2 of the Osaka market, and the second procedure is stored in the market-linked procedure storage section 24-1 of the Tokyo market.

First, it is assumed that the Tokyo market is held. In this case, the company A and the company E collate and the transaction is established. This result is sent from the Tokyo market to the Osaka market.

In the Osaka market, the above procedure 1 is started from the market interlocking unit 25-2, and the purchase application data storage unit 12-
Delete the corresponding data from 2 and cancel the application of Company E in the Osaka market. As a result, there will be no duplication because it will not be the target of verification in the Osaka market.

Next, the operation procedure of the central market system 1 of this embodiment will be described with reference to FIG. Figure 2
5 (a) is the procedure of the central market system 1-1,
(B) is the procedure of the central market system 1-2, and the procedure is the same in all cases. As mentioned above, the electronic market is repeatedly opened at scheduled times,
In FIG. 25, the description for repetition is omitted and only the procedure for one electronic market is shown.

The central market systems 1-1 and 1-2 respectively accept the application from the client system 3 (steps S81-1 and S81-2).

[0280] If the received data is purchase application data,
This is stored in the purchase application data storage unit 12-1, and if the received data is sales application data, it is stored in the sales application data storage unit 13-1 (steps S82-1 and S8).
82-2).

In the case of duplicate application as described above, the interlocking procedure as described above is registered in the market interlocking procedure storage unit 24-1.

[0282] Steps S82-1, S8
2-2 is repeatedly performed according to the reception of the application.

In each system, the collation is started at the market opening time.

[0284] First, prior to the verification, if there is a notification of the closing of a duplicate application from the other central market systems 1-2 and 1-1 (steps S83-1 and S83-).
2) The interlocking process is performed based on the notification as described above (steps S84-1 and S84-2). For example, cancel data corresponding to contracts closed in other markets.

Next, the collation units 14-1 and 14-2 collate the application for sale from the market client system 3 to establish the sale (step S85-1 and step S85-2).

As a result of the collation, if the closed contract is related to the duplicate application, the other central market systems 1-2 and 1-1 related to the overlap are notified of the closed contract (step S).
86-1 and step S86-2).

The above procedure is performed in each market.
It is repeated until the collation is completed (step S87).
-1 and step S87-2).

As described in the first embodiment,
Notification processing is performed as necessary.

On the other hand, the market client system 3 on the selling side or the purchasing side, which is going to participate in the market, also receives the information on the duplicate application in the central market system 1-.
Notify 1, 1-2. And the central market system 1-
Wait for notification from 1, 1-2.

Each market client system 3 participating in the market can know that the purpose of the application has been achieved by receiving the notification that the transaction has been established. Further, since the notification that the transaction has not been established is received and the notification that the transaction has been established has not been sent, it can be known that the purpose of the application has been achieved.

In the case where only a part of the application quantity is closed as described in the first embodiment,
The contract may not be closed only in part, or other central market systems may be notified of the fact that only part of the contract has been closed and the quantity thereof, and the other central market system that has received the notification will receive part of the contract regarding the data. It may be possible to cancel only the quantity of (the quantity in the data is updated), or to notify the other central market system of the fact that only part of the contract has been closed and the quantity, and the other central market system that has received the notification All the data may be canceled.

In this embodiment, the interlocking of two markets has been described, but it is also possible to interlock three or more markets.

(Eighth Embodiment) Next, an eighth embodiment of the present invention will be described.

FIG. 28 shows the configuration of the electronic market system according to the eighth embodiment of the present invention. Further, FIG. 29 shows an example of an operation procedure of the central market system according to the present embodiment.

In this embodiment, the electronic market system includes two central market systems 1-1 and 1-1 at the market opening site.
1-2 and a plurality of market client systems 3 at the market participants' sites.

The present embodiment is the second method of controlling duplicate applications in the distributed electronic market. That is, in the seventh embodiment, interlocking processing for interlocking a plurality of overlapping markets is performed by, for example, notifying the markets of overlapping applications to a plurality of markets, but in the present embodiment, interlocking processing is performed. Instead, the market client system 3 is inquired about the contract to be made, and the contract is made only when the approval response is received from both the purchasing side and the selling side.

Central market system 1-1 according to the present embodiment
Is a configuration in which a confirmation processing function for the market client system 3 is added to the configuration of the first embodiment.
Input unit 11-1, purchase application data storage unit 12-1, sales application data storage unit 13-1, collation unit 14-1, notification unit 1
5-1 and the confirmation part 26-1 are provided.

The central market system 1-2 has the same configuration as the central market system 1-1, and the input unit 11-
2, a purchase application data storage unit 12-2, a sales application data storage unit 13-2, a collation unit 14-2, a notification unit 15-2, a confirmation unit 26-2.

Although the market client system 3 according to the present embodiment has the response unit 35, the other configuration / operation is the same as that of the seventh embodiment.

In this embodiment, the central market system 1-
When the sales application and the purchase application are collated, 1 and 1-2 confirm with the target market client system 3, respectively. The confirmation units 26-1 and 26-2 in the central market systems 1-1 and 1-2 respectively issue confirmation request messages to both of the market client systems 3 for which the trading has been verified, and reply from the market client systems. wait. The market client system 3 can avoid duplicate sales by issuing an approval response to duplicate sales only once and rejecting other sales.

Next, the inter-market linkage process will be described using a specific example. Here, the same example as that used in the seventh embodiment is used (FIGS. 26 and 27).

As described above, in the present embodiment, the central market systems 1-1 and 1-2 make inquiries to both market client systems 3 with respect to the collated result, and a transaction is established with respect to the confirmed result. .

Here, it is assumed that the Tokyo market and the Osaka market are opened almost at the same time and collation is performed. As a result, Company A and Company E collate in the Tokyo market, and Company C and Company E collate in the Osaka market.

In this case, the central market system 1-1 for opening the Tokyo market sends a confirmation request message to the corresponding market client system 3 (company A and company E) to open the Osaka market. At 2, the confirmation request message is sent to the corresponding market client system 3 (Company C and Company E).

As a result, the confirmation request message arrives at company E from both the Tokyo market and the Osaka market. In the market client system 3, when a plurality of confirmation request messages arrive, it is arbitrary as to which determination method determines which one responds to the approval. However, here, E company arrives earlier. Approval will be returned to those who did, and denial will be returned to those who arrived late. In this case, the confirmation request message from the Osaka market arrives earlier and the approval is returned to the Osaka market. In addition to this, as another determination method, for example, in the case where only a part of the application quantity is closed as described in the first embodiment, the approval response is given to the one with a larger quantity. A method of notifying is also possible.

In the central market system 1-1 and 1-2, since the transaction is established only when the approval response is received from both the market client system 3 on the purchase side and the market side on the sales side, in this example, the company E in the Tokyo market is Since the denial reply was received, the transaction between Company A and Company E was canceled, while in the Osaka market, the transaction was completed with the approval response from both Company C and Company E. It should be noted that the Tokyo market and the Osaka market are successively checked, but since there is nothing else to check, the check ends.

As described above, the market client system 3
You can avoid duplication by contacting.

Next, the operation procedure of the central market system 1 of this embodiment will be described with reference to FIG. Figure 2
9 (a) is the procedure of the central market system 1-1,
(B) is the procedure of the central market system 1-2, and the procedure is the same in all cases. As mentioned above, the electronic market is repeatedly opened at scheduled times,
In FIG. 25, the description for repetition is omitted and only the procedure for one electronic market is shown.

The central market systems 1-1 and 1-2 respectively accept the application from the client system 3 (steps S91-1 and S91-2).

[0310] If the received data is purchase application data,
This is stored in the purchase application data storage unit 12-1, and if the received data is sales application data, it is stored in the sales application data storage unit 13-1 (steps S92-1 and S9).
92-2).

Note that steps S92-1 and S9 are performed.
2-2 is repeatedly performed according to the reception of the application.

In each system, when the market opening time comes, the collating units 14-1 and 14-2 collate the application for sale from the market client system 3 to establish the sale (step S93-1 and step S93). −
2).

Next, as described above, the market client systems 3 on both the purchase side and the sales side, which are targets, are confirmed about what can be closed, and there is an approval response from both market client systems 3. Only if this occurs, the contract is closed, and in other cases, the transaction is not established (step S94-1 and step S94-).
2).

Then, information such as the fact that the contract has been concluded or the fact that the contract has not been concluded is transmitted to the market client system 3 (steps S95-1 and S95-2).

The above collation processing and confirmation processing are repeated in each market until the collation is completed (step S87-1 and step S87-2).

Incidentally, as described in the first embodiment,
Notification processing is performed as necessary.

On the other hand, the market client system 3 on the selling side or the purchasing side, which is going to participate in the market, also receives information about duplicate applications in the central market system 1-.
Notify 1, 1-2. And the central market system 1-
Wait for notification from 1, 1-2.

Each market client system 3 participating in the market can know that the purpose of the application has been achieved by receiving the notification that the transaction has been established. Further, since the notification that the transaction has not been established is received and the notification that the transaction has been established has not been sent, it can be known that the purpose of the application has been achieved.

It should be noted that although all the applications are confirmed in the above, if there are duplicate applications as in the seventh embodiment, that effect is indicated by the market client system 3.
From each of the central market systems 1-1 and 1-2 to which the duplicate application is applied, and in each of the central market systems 1-1 and 1-2, the duplicate information is registered, and the confirmation process is related to the duplicate application. You may do it only.

In the present embodiment, the interlocking of two markets has been described, but interlocking of three or more markets is also possible.

(Ninth Embodiment) Next, a ninth embodiment of the present invention will be described.

FIG. 30 shows the configuration of an electronic market system according to the ninth embodiment of the present invention. Further, FIG. 31 shows an example of an operation procedure of the central market system according to the present embodiment.

In this embodiment, the electronic market system includes two central market systems 1-1 and 1-1 at the market opening site.
1-2 and a plurality of market client systems 3 at the market participants' sites.

The present embodiment is the third method for controlling duplicate applications in the distributed electronic market. In this embodiment, the market client system 3 side that participates in multiple markets redundantly creates a time-dependent procedure that is set to participate in one market at the same time and sends it to the central market systems 1-1 and 1-2. Central Market System 1-1, 1
In No. 2, the application data is updated according to the received time-dependent procedure.

Central market system 1-1 according to the present embodiment
Is a configuration in which the function of the time-dependent procedure is added to the configuration of the first embodiment. The input unit 11-1, the purchase application data storage unit 12-1, the sales application data storage unit 13-1, and the collation unit 14- 1, a notification unit 15-1, a time-dependent procedure storage unit 27-1, and a time updating unit 28-1.

The central market system 1-2 has the same structure as the central market system 1-1, and the input unit 11-
2, a purchase application data storage unit 12-2, a sales application data storage unit 13-2, a collation unit 14-2, a notification unit 15-2, a time-dependent procedure storage unit 27-2, a time update unit 28-2 There is.

In this embodiment, the market client system 3 that simultaneously participates in a plurality of markets registers the participation time in a time-dependent procedure in advance. Central market system 1-1,
In 1-2, the time update unit 2 is set for each market opening time.
8-1 and 28-2 are activated and a time-dependent procedure is executed to switch duplicate applications every hour, thereby controlling duplication.

Next, the time update by the time-dependent procedure will be described using a specific example.

Here, each central market system 1-1, 1
It is assumed that the matching start time and the matching end time at -2 have been disclosed in advance. It is assumed that the central market systems 1-1 and 1-2 collate the trading application submitted by the collation start time and send the result to the market client system 3 by the collation end time.

In this example, the Tokyo market is the central market system 1
-1 opened, Osaka market is the central market system 1-
2 shall be established. Further, the matching start time and the matching end time of the Tokyo market are as shown in FIG. 32,
It is assumed that the collation start time and collation end time of the Osaka market are as shown in FIG.

The market client system 3 that intends to participate in both the Tokyo market and the Osaka market determines the optimum market participation method by checking the overlap of the market opening times of both markets. For example, when the matching start time and the matching end time are as shown in FIG. 32 and FIG. 33, if scheduling is performed as shown in FIG. 34, there is no overlap at the same time.

The market client system 3 obtains a market participation time without duplication in advance, expresses it as a time-dependent procedure, and sends it to the central market systems 1-1 and 1-2. The expression of this procedure may be a simple list of participation times or a procedure expression using regularity. In addition,
The application data may be transmitted each time as in the first embodiment, may be transmitted as time series data in the second embodiment, or may be transmitted as a procedure in the fifth embodiment. It may be transmitted, or may be added during the time-dependent procedure and transmitted.

In the central market systems 1-1 and 1-2, whether or not each market client system 3 participates by activating a time-dependent procedure by the time updating units 28-1 and 28-2 at each market opening time. In the case of participation, the application data is stored in the purchase application data storage units 12-1 and 12-2 or the sales application data storage units 13-1 and 13-2, and collation is performed. In this way, overlap between decentralized markets can be achieved.

Next, the operation procedure of the central market systems 1-1 and 1-2 of this embodiment will be described with reference to FIG. It should be noted that in FIG. 31, description for repetition is omitted, and only the procedure for one electronic market is shown.

The central market system 1-1 receives an application from the market client 3 at any time, and when a time-dependent procedure is received, this is received by the time-dependent procedure storage unit 27-.
It shall be stored in 1.

In the central market system 1, when the opening time comes (or the set time before the opening time comes), first, the time updating unit 28-1 causes the time-dependent procedure storage unit 27-1. The time-dependent procedure created by the market participant is read from (step S101).

Next, the updating unit 27-1 determines whether or not to participate in the market at the next time by executing the time-dependent procedure, and obtains application data for participation (step S102). .

If it is decided not to participate in the next market (step S103), nothing is stored in the purchase application data storage unit 12 and the sales application data storage unit 13.

If the market is to be rejoined (step S103), the updating unit 27-1 determines that the requested application data is for the purchasing side (step S104), and the purchasing application data storage unit stores it. 12-1 (step S105), and if the requested application data is for the sales side (step S104), it is stored in the sales application data storage unit 13-1 (step S106).

The above operation is repeated until there is no corresponding procedure (step S25).

If the purchase application data and the sales application data are accepted without notifying the time-dependent procedure, the purchase application data and the sales application data transmitted from the market client system are also stored in the purchase application data storage unit 12-1. Stored in the sales application data storage unit 13-1.

Next, if all the data settings have been completed (if the settings have been completed before the opening time, the opening time has come), then the matching processing / notification unit 15-1 by the matching unit 14-1. Notification processing is performed (steps S108, S
109).

Here, regarding the contracts that have been closed, the central market system 1-2 corresponding to the other market described in the time-dependent procedure is notified of the information, and the other central market that has received the notification. In the system 1-2, all corresponding information is deleted.

In addition, as described in the first embodiment, in the case where only a part of the application quantity is closed,
The contract may not be closed only in part, or other central market systems may be notified of the fact that only part of the contract has been closed and the quantity thereof, and the other central market system that has received the notification will receive part of the contract regarding the data. It may be possible to cancel only the part of the data corresponding to the quantity (update the quantity in the data), or notify the other central market system of the fact that only a part was closed and the quantity and received the notification. Other central market systems may cancel all corresponding information.

In the central market system 1-1, as post-processing, data is deleted from the purchase application data storage unit 12-1 and the sales application data storage unit 13-1 and a time-dependent procedure corresponding to the contracted product is executed. Time-dependent procedure storage unit 16
Delete from -1 and move to the preparation for the next market opening.

Note that, as described in the first embodiment,
Notification processing is performed as necessary.

The same applies to the central market system 1-2.

On the other hand, the market client system 3 on the selling side or the purchasing side who wants to participate in the market has a time-dependent procedure when applying for the central market system 1-1, 1-
Notify 2. And the central market system 1-1,1-
Wait for notification from 2.

Each market client system 3 participating in the market can know that the purpose of the application has been achieved by receiving the notification that the transaction has been established. Further, since the notification that the transaction has not been established is received and the notification that the transaction has been established has not been sent, it can be known that the purpose of the application has been achieved.

In this embodiment, the interlocking of two markets has been described, but it is also possible to interlock three or more markets in the same manner.

(Tenth Embodiment) Next, the first embodiment of the present invention will be described.
No. 0 embodiment will be described.

FIG. 35 shows the configuration of the electronic market system according to this embodiment.

This electronic market system includes a central market system 101 for operating the market, a plurality of seller-side terminals 103 installed on the sites of sellers participating in the market, and a plurality of terminals installed on the sites of buyers participating in the market. Of the buyer side terminal 102.

As the basic function of the central market system 101, at least one of two functions of providing information about the market and matching is provided. Providing information about the market is a function of obtaining information about a product that the buyer wants to buy from the seller and returning the information to the buyer. With the matching function, the buyer side obtains information about the product that the buyer wants to buy from the seller side, and the central market system 101 collates with the specifications of the buyer side, selects the most suitable one and makes a tentative reservation. It is a function to notify both the buyer side.

Regarding the function of providing information on the market, the buyer side terminal collates the specifications on the buyer side with the information on the seller side. In order to purchase the selected product, the buyer issues a purchase request based on the matching result (however, there is a time difference between the information provision and the issue of the purchase request, and the most suitable product is There is a possibility that the item cannot be purchased due to the product being out of stock). The central market system 101 relays the purchase request form to the seller side, and when the acceptance message comes from the seller side, transmits the transaction establishment notification to the buyer side.

In the matching function, the buyer side clearly describes the specifications. In this case, since there is no time difference between information acquisition and verification, the most suitable product can be reserved in advance.

(Eleventh Embodiment) Next, the first embodiment of the present invention will be described.
The first embodiment will be described.

FIG. 36 shows the configuration of the electronic market system according to this embodiment. The electronic market system includes a central market system 101 that operates a market, a plurality of seller-side terminals 103 installed on sites of sellers participating in the market, and a plurality of buyer-sides installed on sites of buyers participating in the market. It is composed of the terminal 102. The present embodiment provides a function of providing information regarding the market.

Prior to the opening of the electronic market in the electronic market system 101, the seller side product information is stored in advance in the seller product file 114 in the central market system 101.

[0360] The opening of the market is performed on demand when the access on the buyer side occurs.

The central market system 101 sends the request for quotation sent from the buyer side terminal 102 to the buyer side receiving unit 1.
The seller selecting unit 112 retrieves and selects the seller who sells the corresponding product from the seller product file 114. Subsequently, the seller side transmission unit 113 transmits an estimate request to the selected seller and waits for a reply from the seller terminal 103.

On the seller's side, a quote stored for the corresponding product is prepared by a program stored in the terminal 103 or by manual intervention, and is returned to the central market system.

In the central market system 101, when the seller side receiving unit 115 receives the quotes returned from the seller, the seller side receiving unit 115 activates the buyer side transmitting unit 116 and sends them back to the corresponding buyer side.

The above processing is performed within a predetermined time. That is, if there is no reply from the seller within a fixed time, it is considered that there is no reply and the processing is continued. As a result, the buyer side is guaranteed to receive the reply within a fixed time after issuing the quotation request form, and the work efficiency can be greatly improved compared to the market opened at a predetermined time.

The buyer side issues a purchase request form from the returned quotation and sends it to the central market system 101.

In the central market system 101, when the buyer side reception unit 111 receives the purchase request form, the seller side transmission unit 113 transmits it to the corresponding seller terminal.

When the purchase request form is received, the seller side terminal 103 checks the stock / delivery date, etc.
Return any of the rejects to the central market system 101.

The central market system 101 regards the transaction as successful by receiving the accept from the seller side terminal 103, notifies both of the corresponding buyer side terminal 102 and seller side terminal 103, and lights up the transaction. Keep a record.

Central market system 101 is seller terminal 10
If the reject is received from 3, the transaction is unsuccessful,
Buyer-side terminal 10 supported by buyer-side transmitter 116

The present embodiment will be described below using a specific example.

Here, three buyer side terminals (A, B,
C) and three seller-side terminals (X, Y, Z) will be described. The products handled in this market are "apples" and "mandarin oranges". The selling price and inventory of "apples" of companies X, Y, and Z are assumed as shown in FIG. 37, and the selling price and inventory of "mandarin oranges" are assumed as shown in FIG.

From the buyer side terminal 102 of Company A, mandarin orange 1
It is assumed that 00 quotation requests have been sent to the central market system 101.

The buyer side receiving section 111 passes this information to the seller selecting section 112. The seller selection unit 112 searches the seller product file 114 to obtain the seller. Here, it is assumed that the seller product file 114 stores information as shown in FIG.

From this, the seller transmitter 113 knows that there are three sellers of mandarin oranges, X, Y, and Z.
Send the request for quotation of company A to companies X, Y, and Z and wait for a reply.

In the case of this example, company X does not reply because the inventory is insufficient. Company Y replies with an estimate of 120 yen and company Z 100 yen within a fixed time.

The central market system 101 puts these results together and causes the buyer side transmitter 116 to send the result to the company A.
Company Y replies 120 yen and company Z 100 yen within a fixed time.

Upon receipt of the request, the buyer side terminal 102 of the company A selects the company Z, for example, because the company Z is cheaper, for example, or automatically by human intervention, and selects the purchase request form for the company Z within a fixed time. Send to the central market system 101.

Upon receiving the purchase request form from the company A, the central market system 101 refers to the estimate recording file (not shown) and transfers the purchase request form to the corresponding company Z.

Upon receipt of the purchase request form, Company Z checks the stock, determines accept / reject, and returns it to the central market system 101.

The central market system 101 is ac from Company Z.
When accepting the transaction, the transaction is regarded as successful and the company A is notified and a record for certifying the transaction is saved.

FIG. 40 shows the flow of information between Company A, the central market system, and Company Z in the above processing.

(Twelfth Embodiment) Next, the first embodiment of the present invention will be described.
The second embodiment will be described.

FIG. 41 shows the configuration of the electronic market system according to this embodiment. The electronic market system includes a central market system 101 that operates a market, a plurality of seller-side terminals 103 installed on sites of sellers participating in the market, and a plurality of buyer-sides installed on sites of buyers participating in the market. It is composed of the terminal 102. This embodiment provides a matching function.

Prior to the opening of the electronic market in the electronic market system 101, product information on the seller side is stored in advance in the seller product file 114 in the central market system 101.

[0385] The opening of the market is performed on demand when the access on the buyer side occurs. However, it is possible to handle a plurality of buyer-side accesses that arrive within a fixed time all at once. By collectively handling as described above, it becomes possible for the seller side to incorporate a function of selecting a buyer.

The central market system 101 sends the request for quotation sent from the buyer-side terminal 102 to the buyer-side receiving unit 1.
11, and transmits them collectively to the seller selection unit 112 within a fixed time, and searches and selects the seller who sells the corresponding product from the seller product file 114. Subsequently, the seller side transmission unit 113 transmits an estimate request to the selected seller and waits for a reply from the seller terminal.

[0387] On the seller side, a program stored in the terminal 103 or manual intervention creates a quote for the corresponding product and sends it back to the central market system 101.

In the central market system 101, when the seller side receiving unit 115 receives the quotation returned from the seller, the collating unit 117 performs matching. The matching unit 117 registers the most suitable seller-buyer pair as a tentative reservation as a result of matching, and the buyer-side transmitting unit 1
At 15, the items are returned to the corresponding buyers.

When the buyer side receives the returned temporary reservation form, it issues a purchase request form within a fixed time and sends it to the central market system 101.

[0390] In the central market system 101, if the purchase request is received by the buyer side reception unit 111, it is considered that the transaction has been completed, and the corresponding buyer side terminal 102 and seller side terminal 1
Both parties will be notified and a record will be kept for lighting the transaction. If the purchase request form is not sent from the buyer-side terminal 103 within a fixed time, it is considered that the transaction has not been completed, and the temporary reservation is canceled.

The present embodiment will be described below using a specific example.

As for the products to be handled and the products of the seller, the eleventh embodiment, that is, FIGS. 37, 38 and 39.
Same as. In the present embodiment, the buyer side specifies purchase conditions for verification in the estimate request form.

A quotation request form is transmitted from the buyer side terminal 102 of Company A. In this quotation request form, 50 apples,
It is assumed that the purchase condition that the price is 100 yen or less is presented. Similarly, from company B, 50 apples are priced at 120.
It is assumed that the purchase condition of less than a yen is presented.

In the central market system 101, the buyer side receiving section 111 passes this information to the collating section 118. The collating unit 118 knows from the seller's merchandise file 114 that the apples are handled by companies X and Y, sends the purchase conditions of the companies A and B to the companies X and Y, and waits for a reply.

Company X and company Y make the following responses to the purchase conditions of company A and company B. However, since the selling price of apples of company Y is 120 yen and the purchase conditions of company A are not satisfied, it is assumed that there is no reply from company Y to company A. Reply from company X to company A: Price 100 yen, number of 50 replies from company X to company B: Price 100 yen, number of 50 replies from company Y to company A: reply Reply from company Y to company B : Price 120 yen, quantity 50 The seller side receiver 115 of the central market system 101 is X
When this information is received from the company Y and the company Y, it is passed to the collation unit 117 and the collation is started. In this case, since the stock of company X is 50, it cannot be sold to both company A and company B.

Various collating methods in the collating unit 117 are conceivable, but here, the sellers are arranged randomly, and matching is performed as long as there is stock in that order. FIG. 42 shows an example of the procedure of this matching process.

An example of matching will be described below with reference to the flowchart of FIG.

First, in step S111, a pair of seller and buyer is created. In this example, p is the following three. (Company X, Company A), (Company X, Company B), (Y Company, Company B) In addition, the left element in the parentheses is the seller, and the right element is the buyer.

In step S112, the buyers are arranged in order. In the first case, b (1) is company A, b (2)
The case where the company B is described will be described.

In step S113, b (1) is e
Since it is not mpty, the process proceeds to step S114.

At step S114, the answer to company A is only company X, so step S115 is passed, and at step S116, company A and company X collate by matching, and this is registered as a temporary reservation.

Next, in step S117, the stock of company X is adjusted. Since the stock of X company is 50 pieces, the stock of X company becomes out of stock due to the sales to A company, and it becomes impossible to sell from X company to B company. Therefore, in step S118, (X company, B
Company) is removed from p.

With the above, the processing of company A is completed, and then b (2)
Move to company B's processing.

Since the answers (company X, company B) have been removed from p, the answer to company B is Y in step S114.
Only company.

At step S116, company B and company Y match and register this as a temporary reservation. Similarly Y
Company's inventory is 100, so 50 sold to Company B
Reduce the number of items to 50.

Returning to step S113, b (3) is em
Since it is pty, the process ends. By performing matching of company A in this way first (company X, company A),
Two provisional reservations (Company Y and Company B) are established.

On the other hand, if the order of b is B company, then A company (b (1) is B company and b (2) is A company),
In step S114, the answers to company B are both company X and company Y. In step S116, since company X has a lower price in matching, company B and company X collate and register this as a temporary reservation.

In step S117, the stock of company X is adjusted, and the company X is out of stock due to the sales to company B.
Company, A company) is removed from p.

[0409] Next, the process of company A is moved to, but step S11
In step 4, the answer to the company A becomes empty, and the company A ends without matching by the check in step S115.

(Thirteenth Embodiment) Next, the first embodiment of the present invention will be described.
The third embodiment will be described.

FIG. 43 shows the configuration of the electronic market system according to this embodiment. The electronic market system includes a central market system 101 that operates a market, a plurality of seller-side terminals 103 installed on sites of sellers participating in the market, and a plurality of buyer-sides installed on sites of buyers participating in the market. It is composed of the terminal 102.

In the eleventh and twelfth embodiments, each time a request for quotation is accessed from the buyer side terminal, communication relating to the quote and purchase request is performed with the corresponding seller side terminal. Then, the central market system 1
By holding information about sales such as price, stock, and delivery date of the product for each seller in the seller product file 114 in 01, information provision and matching can be performed by the central market system without communicating with each seller terminal 103 each time. This can be realized within 101.

As in the twelfth embodiment, the central market system 101 receives the quotation request form sent from the buyer side terminal within a fixed time by the buyer side receiving section 111, and collectively receives it in the collating section 118. introduce. In the collation unit 118, when the seller product file 114 is searched and the sales information of the corresponding product is obtained, the buyer side reception unit 113.
The matching with the specification of the buyer's request for quotation received further is performed by the procedure of the twelfth embodiment, for example.
The matching unit 118 registers the most suitable seller-buyer pair as a tentative reservation as a result of matching, and the buyer-side transmitting unit 113 returns the pair to the corresponding buyer side.

When the buyer receives the returned temporary reservation, the buyer issues a purchase request within a fixed time and sends it to the central market system 101. In the central market system 101, if the purchase request is received by the buyer-side receiving unit 111, it is considered that the transaction has been established, and both the corresponding buyer-side terminal 102 and seller-side terminal 103 are notified and a record for certifying the transaction. To save. If the purchase request form is not sent from the buyer-side terminal 102 within a fixed time, it is considered that the transaction has not been completed, and the temporary reservation is canceled.

[0415] It should be noted that the correction of information regarding sales such as the price, stock, and delivery date of the seller's product in the seller product file 114 is performed through the correction unit 119.

(Fourteenth Embodiment) Next, the first embodiment of the present invention will be described.
The fourth embodiment will be described.

FIG. 44 shows the configuration of the electronic market system according to this embodiment. The electronic market system includes a central market system 101 that operates a market, a plurality of seller-side terminals 103 installed on sites of sellers participating in the market, and a plurality of buyer-sides installed on sites of buyers participating in the market. It is composed of the terminal 102. This embodiment provides a matching function.

First, the seller registers the purchase quantity-unit price correspondence table 1140 in the seller goods file 114 of the goods handled by the seller. The purchase quantity-unit price correspondence table records the number of products sold and the unit price at that time. Usually, a unit price is often set low for a person who purchases a large amount of products. Therefore, the purchase number-unit price correspondence table 1140
May have multiple entries. Also, the unit price and the number of units sold may change depending on the inventory of the seller,
In that case, the purchase quantity-unit price correspondence table 1140 is updated each time. The information of the seller product file 114 and the purchase quantity-unit price correspondence table 1140 are corrected through the correction unit 119.

When the quotation request division unit 120 receives the quotation request from the buyer, the quotation request dividing unit 120 refers to the purchase quantity-unit price correspondence table 1140 of each seller who sells each product so that the overall purchase price becomes the lowest. First, decide which seller and how many to order. Accordingly, the estimation request dividing unit 120 divides the estimation request and transmits the divided estimation request to each seller.
The quotation request dividing unit 120 waits until the quotation request is received for all the divided quotation requests, and returns them to the buyer together.

This embodiment will be described below using a specific example.

It is assumed that Buyer A wants to purchase 100 melons. Regarding "melon", two sellers X
Company and company Y, and the seller product file 114 is shown in FIG.
It is assumed that a purchase quantity-unit price correspondence table for company X such as No. 5 and a purchase quantity-unit price correspondence table for company Y as shown in FIG. 46 are registered. Note that Company Y has a limited inventory and cannot sell more than 80 pieces.

The case where the unit price is the lowest is the case of purchasing 40 or more pieces from the Y company, but the buyer A tries to purchase 100 pieces, whereas the Y company can sell only 80 pieces. It is necessary to divide into companies and purchase.

Here, FIG. 47 shows how the purchase price changes when the purchase quantity of 100 pieces is distributed to X company and Y company. The vertical axis shows the purchase amount and the horizontal axis shows the number of items purchased from company Y. In other words, the left end is melon 100
When all the pieces are purchased from company X, the right end shows the case where all 100 melons are purchased from company Y (however, this can not be realized because only 80 pieces can be purchased from company Y). The part shown in bold is the purchase price, but company X,
Since the purchase price changes discontinuously depending on the number of sales in which the unit price of the melon of Company Y is discontinuous, the purchase price may be the lowest at these positions.

FIG. 48 shows an example of the processing procedure of the estimate request dividing unit 120.

First, the quotation request dividing unit 120 checks all the purchase quantity-unit price correspondence tables 1140 for selling melons, and lists the optimum combination of sales quantity (step S121). Seller X in this example
Since the number of purchases whose unit price changes is 50 and the number of purchases of the seller Y whose unit price changes is 80, a candidate for the optimum purchase number is extracted as follows. (X, Y) = (100, 0), (60, 40), (5
0, 50), (20, 80) Subsequently, the estimation request dividing unit 120 calculates the total purchase cost for each candidate (step S).
122). In this example, the result is as follows. (100, 0): 100 * 70 + 0 * 80 = 7,000 (60, 40): 60 * 70 + 40 * 60 = 6,600 (50, 50): 50 * 70 + 50 * 60 = 6, 500 (20,80): 20 * 100 + 80 * 60 = 6,800 As a result, it can be seen that purchasing 50 pieces from each of X company and Y company has the lowest cost. Therefore, in the case of this example, the combination of (X, Y) = (50, 50) is determined (step S123).

Therefore, the estimate request dividing unit 120
The quoting request for 100 melons from is divided into a quoting request for 50 melons for X and a quoting request for 50 melons for Y company, and each is sent to X company and Y company (step S124).

The quotation request division unit waits for the quotation from company X and company Y (step S125), and returns them together to A (step S126).

The function relating to this quotation request division can be implemented in combination with any of the tenth to thirteenth embodiments.

(Fifteenth Embodiment) Next, the first embodiment of the present invention will be described.
The fifth embodiment will be described.

The present embodiment relates to the function of recording the transaction establishment process in the tenth to twelfth embodiments.

In the present embodiment, first, the basic transaction number is added to the quotation request form on the buyer side for management. Two forms are shown as an example of this processing.

FIG. 49 shows the first form. In this form, the buyer's terminal 102 sends a request for quotation to the buyer's receiver 111 of the central market system 101. Upon receiving the quotation request form 160, the buyer side receiving unit 111 acquires the transaction basic number from the transaction basic number assigning unit 151, adds the transaction basic number to the quotation request document, and advances the processing as a transaction basic number-added quotation request 161.

A second form is shown in FIG. In this mode, the buyer side terminal 102 sends a transaction basic number issuance request to the buyer side receiving unit 111 of the central market system 101. The buyer-side receiving unit 111 acquires the transaction basic number from the transaction basic information assigning unit 151, and transmits the transaction basic number to the buyer-side terminal 102 through the buyer-side transmitting unit 116. At the buyer's terminal 102, the transaction basic number is added to the quotation request, and the quotation request 162 with the transaction basic number is added again to the central market system 10.
Send to 1.

[0434] The difference between the first form and the second form is that in the second form, the basic transaction number can be recorded when the buyer-side terminal 102 issues a request for quotation.

Next, FIG. 51 shows an example of the configuration in which the record of the transaction process is recorded in the market log file in the central market system 101. Here, it is assumed that the transaction basic number is attached to the estimate request form, the estimate form, and the purchase request form according to the first or second mode.

When the central market system 101 receives a request for quotation from the buyer-side terminal 102, it sends them to the first order.
According to the procedures of the 0th to 12th embodiments, the seller side terminal 1
Send to 03. At that time, in the transaction process recording unit 152, a copy of the quotation request form is connected to the link corresponding to the transaction basic number in the market log file 153.

In the central market system 101, when the quotation is received from the seller side terminal 103, the market log file 1 based on the basic transaction number added to the quotation.
The corresponding quotation request form is retrieved from 53. Then, it is checked whether the description items such as the product name, the number of pieces, the price, and the delivery date in the estimate match the conditions of the items described in the estimate request form.

If they do not match, a predetermined process such as invalidating the quotation or sending a warning message to the seller side terminal 103 and returning the quotation is performed.

When the items described in the quotation and the items requested in the quotation match, the quotation is sent to the terminal on the buyer side according to the procedures of the tenth to twelfth embodiments. At that time, in the transaction process recording unit 152, a copy of the quotation may be connected to the link corresponding to the transaction basic number in the market log file 153.

In the central market system 101, when receiving the purchase request form from the buyer side terminal 102, a corresponding estimate form is obtained from the market log file 152 based on the transaction basic number added to the estimate form and the seller's company name. Search for. Then, it is checked whether the description items such as the product name, the number of products, the price, the delivery date, and the seller company in the purchase request form match the conditions of the description items in the quotation.

If they do not match, a predetermined process such as invalidating the purchase request form or sending a warning message to the buyer side terminal 102 and sending back the purchase request form is performed.

If the items stated in the purchase request form and the items stated in the quotation match, the purchase request form is sent to the terminal 103 on the seller side in accordance with the procedures of the tenth to twelfth embodiments. At that time, in the transaction process recording unit 152, a copy of the purchase request may be connected to the link corresponding to the transaction basic number in the market log file 153.

Here, FIG. 52 shows an example of the structure of the market log file 153, and FIG. 53 shows an example of the procedure for the central market system 101 to create the market log file 153.

Then, the contents described in the corresponding quotation and the quotation request are compared, and if the contents match (step S140), a message is sent to the buyer side terminal (step S144). On the other hand, if the contents of description do not match (step S140), a predetermined exception process is performed (step S141).

If the message received in step S131 is a purchase request form (step S134), first, the corresponding quote is searched from the market log file (step S136). Then, the contents described in the corresponding quotation and the quotation request are compared, and if the contents match (step S137), a message is sent to the seller side terminal (step S143). On the other hand, if the described contents do not match (step S137), a specified exception process is performed (step S138).

If the message received in step S131 does not correspond to any of the estimate request form, the estimate form, and the purchase request form (steps S132 to S134),
The specified exception processing is performed (step S135).

The market log file 153 according to this embodiment can also be used as evidence of a contract in an activity related to the transaction outside the electronic market system 101 (delivery of an actual product, etc.). Further, after the transaction is established, it is possible to secure the area of the market log file 101 by erasing all the logs relating to the transaction or the logs for which only the estimation has been performed.

(Eighteenth Embodiment) Next, the first embodiment of the present invention will be described.
8th Embodiment is described.

This embodiment relates to security between the central market system and terminals on the seller side and the buyer side, and can be implemented in combination with each of the first to seventeenth embodiments.

FIG. 62 shows the configuration of the electronic market system according to this embodiment. The seller-side terminal 102 and the buyer-side terminal 103 are called clients for convenience. The client side comprises a terminal 1002 and a device 1020. The terminal 1002 has a user interface with a seller or a buyer.

When information is sent to the central market system 1001 on the client side, the transmission data created by the terminal 1002 is first sent to the device 1020.

In the device 1020, a clock 1025, a device-specific ID 1024 and a serial number 1029 are added and encrypted by the encoder 1023. The encrypted data is stored in the storage device 1026, and the encrypted data is passed to the terminal 1002 and transmitted.

Whether or not the transmission is successful is also determined by the device 10
It is stored in the recording device 1026 in the storage unit 20. This information is also encoded and stored together with the time information of the clock 1025.

The serial number is incremented by one each time it is referenced, has a sufficient bit width, and becomes 0 again if the serial number overflows.

When the client side receives the information from the central market system 1001, the data received by the terminal 1002 is first sent to the device 1020. Since this data is encrypted, the terminal 1002 cannot know its contents.

The device 1020 stores the data in the storage device 1026 together with the time information of the clock 1025 and the serial number 9. Further, the received data is decoder 1
It is decrypted in 028 and returned to the terminal 1002. The terminal 1002 uses the plain text that is obtained by the decoding of the decoder 1028.

The central market system 1001 also encrypts / decrypts the transmission / reception of information and records the time information together with the same procedure as above.

Here, it is conceivable that the clock 1015 of the central market system 1001 and the clock 1025 in the device 1020 on the client side do not always match or there is a deviation. So, the central market system 1
Clock 1 from 001 to client device 1020
025 is set to enable time adjustment. Alternatively, the time of the clock 1025 in the device 1020 of the client is read from the central market system 1001 and the time difference between both clocks is recorded, and the clock of the other party and the own clock are logically synchronized. At this time, the client side also reads the time of the clock 1025 of the central market system 1001 and shifts the clocks (or the central market system 100).
The time itself of the first clock 1025) is recorded in the storage device 1026 in the device 1020.

[0493] Further, the time is adjusted or the time of the other party's clock is read to synchronize the time physically or logically at regular or random time or immediately before or after communication.

[0494] By doing so, it is possible to monitor whether the client side or the central market system 1001 side is in a state where the time is abnormal due to intention or accident. For example, an abnormality is detected when the time difference between the two clocks rapidly increases.

It is preferable to use different keys for the encoder 1023 and the decoder 1028. By doing so, the encoder 1023 cannot restore the encoded data by the decoder 1028. In addition, it is not possible for the encoder 1023 to restore the original decoded by the decoder 1028.

Information in the storage device 1026 in the device 1020 has a function of writing in the storage device in the terminal 1002 before overflow. The written data cannot be deciphered or modified for the above reasons. Moreover, since this encrypted data includes the serial number, it is not possible to delete the data without leaving a trace.

[0497] Neither the client side terminal 1002 nor the central market system 1001 can decrypt this data by itself. This information is the password managed by the central market system and its IC under the witness of a public such as a court.
The contents can be read only by using both the password managed by the side using the card. Furthermore, an electronic notary or certificate authority password may be required as the third password.

It is conceivable that the device 1020 is composed of an IC card. Further, it may have a PCMCIA specification widely used in personal computers and the like. Further, it may be an apparatus of any form having an interface with any computer system such as a personal computer type terminal system.

The above functions can also be realized as software. It is also possible to implement it as a machine-readable medium in which a program for causing a computer to execute the above-mentioned procedures or means is recorded.

The present invention is not limited to the above-described embodiments, but can be implemented with various modifications within the technical scope thereof.
