Embodiments of the present invention will be described below with reference to the drawings.

First, a 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 the present embodiment.

This electronic market system comprises 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 (sales side and purchase side).

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 part in each of the central market system 1 and the individual market client systems 3 is omitted. 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 has an input unit 11 for receiving an application from the market client system 3, a purchase application data storage unit 12 for storing purchase application data, a sales application data storage unit 13 for storing sales application data, and these storages. A matching unit 14 for matching the purchased purchase application data with the sales application data, and a notifying unit 15 for notifying the matching result to the market client system 3 are provided.

The market client system 3 transmits the application information for trading to the market client system 3 and receives a notice of the contract etc. from the market client system 3.

Next, the basic operation of the central market system 1 and the electronic market opened by the central market system 1 will be described with reference to the basic operation procedure of the central market system 1 and the market client system 3 in FIG. And the basic content of
The basic method of the market client system 3 participating 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, it is conceivable that the electronic market is opened at a certain time, for example, every hour from 9:00 am to 3:00 pm.

The central market system 1 notifies the market client system 3 of market opening information such as market contents and market opening time from the notification unit 15 in advance. This notification may be made in response to a request from the market client system 3 or may be periodically made to the market client system 3 registered in advance. Further, the advertisement may be performed for the market client system 3 having no request.

Now, the market client system 3 on the selling side or the purchasing side that intends to participate in the market creates and transmits the application information for buying and selling to the central market system 1 (step S4).

That is, by the market opening time (or the application closing time before that), the market application information is sent from each market client system 3 to the central market system 1.

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

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

In general, verification is established if the lowest selling price is equal to or less than the highest purchase price. When there are a plurality of such combinations, there are several possible combinations to select, but it is necessary to guarantee market equality. For example, there is a method in which a product with a low selling price and a product with a high purchase price are combined in order, and if they are the same, a selection is made randomly. There are several methods for determining the contract price. For example, there is a method of calculating an intermediate value between the selling price and the purchase price.

The central market system 1 notifies the market client system 3 on both the selling side and the purchasing side from the notifying section 15 of the fact that the transaction has been established (step S3). In the case where the transaction has not been established, the market client system 3
May be notified, or the fact that the transaction has not been established may be notified by not receiving the notification that the transaction has been established.

The central market system 1 is provided for all market client systems 3 participating in the market.
It is preferable that the notification unit 15 notify the market information on the market such as the market situation such as the contract price.

Further, it is preferable that the central market system 1 transfers necessary information to a related system in order to cooperate with contract creation, settlement, physical distribution and the like in connection with a successful transaction.

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. In addition, by receiving the notification that the transaction has not been completed, it is possible to know that the purpose of the application has been achieved by not receiving the notification that the transaction has been completed.

When the market client system 3 learns that the transaction has not been established, the market client system 3 refers to the market information notified from the central market system 1, for example, and obtains the sales application information for the next market opening time. To create
Send to the central market system 3 to participate in the market. Alternatively, for example, as a result of examining by referring to the market information notified from the central market system 1, it is determined not to participate in the next market.

Next, the collation processing will be described with some specific examples.

Here, one central market system 1 and 6
It is assumed that the system comprises one market client system 3.

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

In this case, the minimum selling price is 100
Since the yen and the maximum purchase price are the same at 100 yen of F company, a transaction is established between A company and F company. of course,
The transaction price will be 100 yen.

As a second example, Company A sets the desired selling price to 1
It is assumed that 00 yen, Company B is 150 yen, Company C is 180 yen, and the desired purchase price is 80 yen for Company D, 90 yen for Company E, and 120 yen for Company F.

In this case, the minimum selling price is 100
The company and the maximum purchase price are 120 yen for company F, and the minimum selling price is lower, so that the conditions for establishing a transaction between company A and company F are satisfied.

There are various methods for determining the transaction price at this time, and a method of taking an appropriate value between 100 yen and 120 yen is considered. Here, it is assumed that an intermediate value between the two is determined to be 110 yen.

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

In this case, there are a plurality of 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, the company A with the lowest selling price, the company F with the highest purchasing price, the company B with the second lowest selling price, and the company E with the second highest selling price And a transaction shall be established between. Alternatively, a transaction may be established between the company A with the lowest selling price, the company E with the second highest purchasing price, the company B with the second lowest selling price, and the company F with the highest purchasing price.

In the above examples, the unit of transaction is the same for the selling side and the purchasing side. However, as a fourth example, the case where the transaction amount is added will be described.

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

In this case as well, a plurality of possible combinations can be made in the same manner as in the third example. For example, as described above, collation is performed in ascending order of the selling price and descending order of the purchasing price, and the quantity of both is checked The smaller one may be used as the transaction quantity.

In this example, first, a transaction is established between Company A, which has presented the lowest selling price, and Company F, which has presented the highest purchase price. The transaction price is an intermediate value of 115 yen and the quantity is 10 yen of Company A. And 5 which is the smaller of the 5 of Company F is determined. As a result, all the purchase applications of Company F are completed, and are deleted from the purchase company list (purchase application data storage unit 12). However, the remaining sales application of Company A becomes 5, and the seller list (sales application data storage unit 12) 13) Reduce the quantity and continue collation.

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, since all the sales applications of the company A are completed, they are deleted from the sales company list. However, the purchase application of the company E has the remaining amount of 10, and the number of the purchaser list is reduced to continue the collation.

Subsequently, a transaction is established between the companies B and E, and the transaction price is 120 yen and the quantity is 5. As a result, all the sales applications of Company B are completed, and are deleted from the list of sales companies.
Continue matching by reducing the quantity on the buyer list.

Thereafter, since the selling price exceeds the purchase price, no transaction is established.

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

In the present embodiment, the market client system 3 prepares purchase application data or sales application data as trading application information for each market and sends it to the central market system 1. In the present embodiment,
In determining the trading price in the market client system 3, for example, support software for price determination based on market information obtained from the central market system 1 may be used, or the judgment of the user may be involved. .

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

The central market system 1 accepts, from time to time, an application for trading in the next electronic market from the market client 3 (steps S12 and S13) until the time of opening the next electronic market (step S11).

When an application for trading to 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), it is stored in the sales application data storage unit 13
(Step S16), and returns to Step S11.

The above operation is repeated, and when the opening time comes in step S11, the collating unit 14 performs collation processing (step S17).

Then, the notifying unit 15 notifies the matching result to the market client system (step S18).

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

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 wait for reception of the application in preparation for the next registration.

As for the market client systems 3 that have participated in the current market and for which no transaction has been established, as described above, the price or the like for participating in the next market is determined as appropriate, or If the user 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 the present 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, and after the purchase application data storage unit 12 and the sales application data storage unit 13 are initialized in step S19, the next time. In the procedure of FIG. 6, the application reception start time and the application deadline time are also set in advance. The other points are the same as the procedure in FIG.

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

When the reception start time has come (step S11-1), the central market system 1 accepts the current application for trading from the market client 3 to the electronic market 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 as in the procedure of FIG.

When the opening time has come in step S11-3, a collation process / notification process 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 to wait for the next reception start time in preparation for the next registration.

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 be mainly given to each implementation. It is assumed that the embodiment differs 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 the present embodiment, the market client system 3 sends information such as the purchase price at a series of market opening times to the central market system 1 in advance as time-series data. As far as possible, the purchase application data or sales application data is automatically updated for the corresponding market client system 3.

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

As shown in FIG. 7, the central market system 1 according to the present embodiment has a structure similar to that of the first embodiment, and additionally includes a trading application time-series data storage unit 16 and an updating unit 17.
Having.

The time series data storage section 16 stores the sales application time series data previously sent from the market client system 3.

The updating unit 17 extracts the purchase price or the selling price at the corresponding time from the sales application time series data of each market client system 3 in the time series data storage unit 16 at each time when the market is opened. 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 decreasing the sales price or increasing the purchase price over time is automated. .

Here, a description will be given of the sales application time-series data and the automatic update of the purchase application data and the sales application data based on the time series data.

FIG. 9 shows an example of the sales 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 market opening 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, the graph on the selling side generally has a decreasing direction, and the graph on the purchasing side generally has an increasing direction.
By comparing these six graphs at each market opening time, it is possible to determine the establishment of a trade.

In the case of the example of FIG. 9, the selling side A,
The prices of companies B and C are higher than the prices of companies D, E and F on the purchasing side, and the transaction is not established.

At 12 o'clock, the selling price of company A and D
Company and Company F have the same selling price. Therefore, at this point, a transaction is established between Company A and Company D or Company F. Here, it is assumed that a transaction is established between Company A and Company D. Thereafter, the graphs of Company A and Company D are deleted.

Next, the transaction is established between Company C and Company E or Company F at 3:00. Here, it is assumed that the relationship is established between Company F and Company C that present the highest purchase price and the lowest sales price.

As described above, a sales and purchase strategy corresponding to time can be expressed.

Next, an operation procedure of the central market system 1 of the present embodiment will be described with reference to FIG. In addition,
As described above, the electronic market is opened at the scheduled time for repetition. However, 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 receives an application from the market client 3 at any time, and upon receiving the sales application time-series data, stores it in the sales application time-series data storage unit 16.

In the central market system 1, if the opening time has come (or if the set time before the opening time has come), the updating unit 17 sends a trading application to open the next electronic market. The data corresponding to the opening time of the electronic market is read from the series data storage 16 (step S21).

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

The purchase application data and 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 setting is completed (if the setting is completed before the opening time, the opening time is reached), the collating unit 1 as described in the first embodiment is used.
4 and the notification processing by the notification unit 15 is 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. Is deleted from the trading application time-series data storage unit 16, and the process proceeds to preparation for the next market opening.

In the present embodiment, both the application using the purchase application data or the sales application data and the application using the sales application time-series data are accepted, but the application may be entirely accepted using the sales application time-series data. . In this case, when applying only once, data obtained by adding time information to purchase application data or sales application data may be handled as purchase application time-series data.

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

In this embodiment, the central market system 1 notifies each market client system 3 of the minimum value, average value, maximum value of purchase price, average value, total number of sales applications, and total number of purchase applications at each time. The market client system 3 has a function of automatically determining a selling price or a purchasing price at the next time based on the information.

FIG. 10 shows the configuration of the electronic market system according to the present embodiment. FIG. 11 shows an example of an operation procedure of the market client system according to the present embodiment.
FIG. 1 shows an example of an operation procedure of the central market system according to the present embodiment.

The central market system 1 according to the present embodiment comprises:
This is almost the same as the configuration in the first embodiment.

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

The procedure storage section 31 stores procedures for determining a selling price or a purchase price at the next time.

The update unit 32 activates a preset procedure stored in the procedure storage unit 31 and, based on the market information sent from the central market system 1, sells or purchases the price at the next time. To determine. The application data including information on the determined price is sent to the central market system 1 in the same manner as in the first embodiment.

As a result, the market client system 3 can make an automatic judgment according to the market situation.
Automated operation of market participants is improved.

Here, a function of automatically determining a price based on market information will be described.

In this embodiment, it is assumed that the central market system 1 sends information on the previous market to the market client system 3 before the market opening time. Thus, the market client system 3 can determine the next purchase price or sales price by referring to the information.

As a specific example, it is assumed that six companies A to F participate in the market, A and B are sales sides, and C, D, E and F are purchase sides. At this time, it is assumed that the offer prices of the respective companies at the previous market opening time are as shown in FIG. At this point, the minimum sale price was higher than the maximum purchase price, so the deal was not completed. It is assumed that the central market system 1 notifies 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 offer 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 presentations <the total number of purchase presentations, the sales prices are presented as they are. (2) If the maximum purchase offer price <the sales limit price,
I will not show it next time. (3) If the selling price-the maximum offer price <10, the selling price is reduced by half of the difference.

The first condition is a case where the demand exceeds the supply, which means that the seller is bullish and takes measures without lowering the selling price. The second condition is a case where there is no purchase offer beyond the sales margin price. In this case, it is determined that there is no prospect of a transaction, and this means that it will not be presented next time. The third condition is when it is determined that the difference between the offered selling price and the maximum purchase offer price is small,
In this case, it is intended to lower the selling price and aim at closing the transaction.

As described above, a procedure is described in the form of a rule.
If there is a plurality of matches, a method of setting priorities between rules can be considered. The description of the procedure may be in any format.

As described above, by incorporating the procedure for determining the price to be presented at the next market opening time using the market information sent from the central market system 1, the market client system 3 can respond to market conditions. Judgment can be made.

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

The market client system 3 on the selling side or the purchasing side, which intends to participate in the market, prepares the application information for buying and selling 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, in the central market system 1, as in the first embodiment, processing such as acceptance, storage, collation, and notification of application data is performed (step S36). Further, market information is transmitted (step S37).

Now, each market client system 3 that has participated in the market can know that the purpose of the application has been achieved by receiving the notification that the transaction has been established. In addition, by receiving the notification that the transaction has not been completed, it is possible to know that the purpose of the application has been achieved by not receiving the notification that the transaction has been completed.

When 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 procedure is started by the updating unit 32, and the selling price or purchase price at the next time is determined based on the market information (step S34). ). In addition, you may make it generate | occur | produce the next sales application time series data based on not only the market information immediately before but also the history of past market information.

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

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

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

In the present embodiment, as in the second embodiment, the market client system 3 sends information such as the selling price at a series of market opening times to the central market system 1 as application time-series data in advance. 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 the time-series data exists,
As in the third embodiment, the market client system 3
Generates the following 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. This function is provided.

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

9

[0183] The time series data storage unit 18 stores the sales application time series data previously sent from the market client system 3.

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

Thus, the communication between the central market system 1 and the market client system 3 can be reduced, and the operation of gradually decreasing the selling price or increasing 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 update unit 34 in addition to the configuration in the first embodiment.

[0187] The procedure storage unit 33 stores procedures for deciding the next trade application time-series data. In addition,
In the third embodiment, the procedure is for determining the next trading application data. However, in the case of this embodiment, in order to determine the time-series data, as a procedure, for example, an increase in price over time or Rules for setting or modifying the slope of the decrease, rules for setting or modifying the manner in which the price changes over time (the shape of the time-price curve; see FIG. 9), and the like are included.

The update unit 34 activates a preset procedure stored in the procedure storage unit 33, and determines the next sales application time-series data based on the market information sent from the central market system 1. . Note that the determined trade application time-series data is sent to the central market system 1 in the same manner as in the first embodiment.

As a result, the market client system 3 can make an automatic decision according to the market situation,
Automated operation of market participants is improved.

Next, an operation procedure of the central market system 1 of the present embodiment will be described with reference to FIG. As described above, the electronic market is opened at the scheduled time of repetition. However, in FIG. 16, 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 upon receiving the trading application time series data, stores it in the trading application time series data storage unit 16.

In the central market system 1, if the opening time has come (or if the set time before the opening time has come), the updating unit 19 sends a trading application to open the next electronic market. The data corresponding to the opening time of the electronic market is read from the series data storage unit 18 (step S41).

Next, if the read data is for the purchaser (step S42), the updating unit 19 stores this as purchase application data in the purchase application data storage unit 12 (step S43), and reads the read data. Is the sales side (step S42), this is stored in the sales application data storage unit 13 as sales application data (step S42).
44).

The purchase application data and 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 have been completed (if the setting has been completed before the opening time, the opening time has come), the verification processing / notification section 15 by the verification section 14 is performed.
(Steps S46 and S47).

In the central market system 1, as post-processing, the 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 completed sales application time series data is deleted. Is deleted from the trading application time-series data storage unit 18 and the process proceeds to preparation for the next market opening.

Next, the operation procedure of the market client system according to the present embodiment will be described with reference to FIG.

The market client system 3 on the selling side or the purchasing side that wants to participate in the market creates and sells the time series data of the sales application 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).

[0200] 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. In addition, by receiving the notification that the transaction has not been completed, it is possible to know that the purpose of the application has been achieved by not receiving the notification that the transaction has been completed.

When 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 sales application time-series data previously transmitted to the central market system 1 includes the next data (step S55), the flow returns to step S52 to notify the result of the next electronic market. wait.

On the other hand, if the sales application time-series data previously transmitted to the central market system 1 does not include the data for the next time (step S55), the update unit 34 starts the procedure and notifies the market. The next sales application time-series data is generated based on the information (step S56). In addition, you may make it generate | occur | produce the next sales application time series data based on not only the market information immediately before but also the history of past market information.

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

If the user again participates in the next market (step S35), the flow returns to step S51, where the time series data of the trading application is transferred to the central market system 1, and the notification of the result is awaited.

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

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

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

In the present embodiment, both the application using the purchase application data or the sales application data and the application using the sales application time-series data are accepted, but the application may be entirely accepted using the sales application time-series data. . In this case, when applying only once, data obtained by adding time information to purchase application data or sales application data may be handled as purchase application time-series data.

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

In the present embodiment, the same functions as those of the third embodiment are included in the central market system 1.

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

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

[0214] The trading application data generation procedure storage unit 20 includes:
Stores a sales application data generation procedure for determining a selling price or a purchasing price at the next time, which is sent in advance from the market client system 3.

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

As a result, it is possible to automatically generate trading application data reflecting market conditions without performing communication between the central market system 1 and the market client system 3 at each market opening time. Further, the operation of gradually decreasing the selling price or increasing the purchasing price over time is automated.

Next, an operation procedure of the central market system 1 of the present embodiment will be described with reference to FIG. As described above, the electronic market is opened at the scheduled time, but the description for the repetition is omitted in FIG. 19, 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 upon receiving the sales application time series data, stores it in the sales application time series data storage unit 16.

In the central market system 1, if the opening time has come (or if the set time before the opening time has come), the updating unit 21 first enters the market entry from the trading application data generation procedure storage unit 20 into the market. The sales application data generation procedure created by the user is read (step S61).

[0220] Next, the updating unit 21 determines the sales price or purchase price at the next time based on the notified market information by executing the sales application data generation procedure, or does not apply next time. It is determined (step S62).

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

If the user re-enters the next market (step S63), if the generated data is for the purchasing side (step S64), the updating unit 17 stores this data as purchasing application data. If the generated data is for the sales side (step S64), it is stored in the sales application data storage unit 13 as sales application data (step S6).
6).

The purchase application data and 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 is reached), the matching processing / notification unit 15 by the matching unit 14 is performed.
(Steps S68, S69).

In the central market system 1, as post-processing, data is deleted from the purchase application data storage section 12 and the sales application data storage section 13, and the sales application time series data corresponding to the contracted one is replaced with the sales application time series data. Data storage unit 16
And move on to preparation for the next market opening. In addition,
Here, it is assumed that the purchase / request time-series data that has been decided not to be applied is also deleted from the purchase / request time-series data storage unit 16 as there is no possibility of applying for the next transition.

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

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. In addition, by receiving the notification that the transaction has not been completed, it is possible to know that the purpose of the application has been achieved by not receiving the notification that the transaction has been completed.

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 accumulate the market information. .

The market client system 3 adds the information of the validity period to the sales application data generation procedure and transmits the information to the central market system 1, and the central market system 1 applies only to the sales application data generation procedure during the validity period. This may be used.

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

In this embodiment, both the application based on the purchase application data or the sales application data and the application based on the time series data of the sales application are accepted. However, the application may be accepted entirely by the procedure for generating the sales application data. . In this case, when applying only once, a purchase application data generation procedure for generating purchase application data or sales application data for one time may be used.

In this embodiment, similarly to the fourth embodiment, the market client system 3 is provided with a function of creating a sales 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 sales 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 configuration, the second to fifth embodiments in which predetermined functions relating to purchase application data and sales application data are added to the central market system and the market client system However, these embodiments can be implemented in any combination.

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

In the following, an embodiment will be described in which overlapping applications to a plurality of markets are realized. The sixth below
In the ninth to ninth embodiments, in order to make the description easy to understand, a case will be described in which the market client system makes an application using purchase application data or sales application data, but among the first to sixth embodiments, Arbitrarily can be applied to each of 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 the present embodiment. FIG. 21 shows an example of an operation procedure of the central market system according to the present embodiment.

[0239] In this embodiment, in the configuration of the first embodiment, the central market system 1 having thereon a function of the electronic marketplace of two systems, and purchasing application data storage unit 12 ₁ dedicated to the first system sales application data storage unit 13 ₁ and the collating unit 14 ₁ is provided, the purchase application data storage unit 12 ₂ and the sales application data storage unit 13 ₂ and the matching unit 14 ₂ is provided exclusively in the second system, an input unit 11 The notification unit 15 is shared by both systems.

The central market system 1 according to the present embodiment has, in addition to the configuration of the first embodiment, a link between the first system electronic market and the second system electronic market.
An interlocking procedure storage unit 22 and an interlocking unit updating unit 23 are provided.

In the present embodiment, it is assumed that one central market system 1 opens an electronic market for a plurality of products. That is, the purchaser wants to participate in an advantageous one of the multiple commodity markets.
In such a case, the market client system 3 fills in 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 which has received this, the interlocking unit 23 performs control so that sales and purchases do not overlap. The interlocking unit 23 includes both matching 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. Thereby, it is possible to link the commodity markets in the market.

Next, an interlocking process between commodity markets will be described using a specific example.

In this example, it is assumed that the markets for “apple” and “orange” are opened at the same time (the apple market is opened in the first system and the orange market is opened in the second system). Here, it is assumed that the buyer can apply for multiple markets at the same time. Also, if it is established in any market, it will have an interlocking function to cancel in other markets.

Here, 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 "orange" and does not need both. If the two markets are independent, in the apple market, a transaction between Company A, which has offered the lowest selling price, and Company E, which has offered the highest purchasing price, has been established. Similarly, a transaction between Company C and Company E has been established in the orange market, Company E has to make duplicate purchases. In order to realize the function of simultaneously applying to a plurality of markets while avoiding such duplication, in the case of overlapping applications, the market client system 3 informs in advance that it is linked to the central market system 1, In this section, we will introduce a method of keeping the linked information and avoiding duplication by changing the application to the other market if one market is established.

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

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

The first-system collation unit 1 of the central market system 1
In 4 ₁ informs the Closing information on interlocking portion 23. The interlocking unit 23 performs matching with a 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. Next, when the orange market is opened, the application for Company E has been canceled, so that a transaction is established between Company C and Company G.

As described above, in the simultaneous opening of markets for a plurality of commodities, it is possible to increase the convenience of market participants by eliminating competition.

Next, the operation procedure of the central market system 1 of the present embodiment will be described with reference to FIG. As described above, the electronic market is set up at the scheduled time, but 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 accepts an 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,
Storing application data in the purchase application data storage unit 12 _2, or sold application data storage unit 13 ₂ (step S72-
2).

[0253] Incidentally, in the case of application of overlapping participation as described above, to be stored in both the both the purchase application data storage unit 12 ₁ and 12 ₂ or sales application data storage unit 13 ₁ and 13 ₂ In addition, the linked procedure as described above is registered in the linked procedure storage unit 22.

Steps S72-1, S7
Step 2-2 is repeatedly performed in response to receiving the application.

[0255] In each system, when it comes to the market opening time, the matching unit 14 _1, 14 ₂ by measuring the establishment of trading by matching application for trading market client system 3 (step S73-1 and step S73-2 ).

As described above, interlocking processing 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
Or the corresponding data is deleted from the sales application data storage unit 13 _2.

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

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

On the other hand, the market client system 3 on the selling side or the purchasing side that wants to participate in the market can also use the central market system 1-
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. In addition, by receiving the notification that the transaction has not been completed, it is possible to know that the purpose of the application has been achieved by not receiving the notification that the transaction has been completed.

As described in the first embodiment, when only a part of the number of applications is closed,
Partial contracts may not be closed, or only partial contracts may be canceled (updated in the data) in the market of another system for only a part of the contract that has been concluded. Alternatively, if only a part is closed, all the data may be canceled in the market of another system.

In the present embodiment, the interlocking of two markets has been described. However, 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 an electronic market system according to the seventh embodiment of the present invention. FIG. 25 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 participant's site.

In the sixth embodiment, a plurality of markets opened in one central market system 1 are linked, but in the present embodiment, two different markets are operated by the same mechanism as in the sixth embodiment. A plurality of markets respectively opened in one central market system 1 are linked.

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

The central market system 1-2 has the same configuration as that of the central market system 1-1.
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 interlock procedure storage unit 24-2, and a market interlock unit 25-2 are provided. I have.

The configuration and operation of the market client system 3 are the same as those of the sixth embodiment, and their description is omitted in FIG.

In the present embodiment, it is assumed that the electronic markets are simultaneously opened in a distributed manner. In other words, the purchaser wants to simultaneously participate in a plurality of dispersed markets and to trade in an advantageous one without duplication of sales in any of the markets. In such a case, the market client system 3 fills in the fact that the application information is duplicated in a plurality of markets, and enters information from both central market systems 1-
1, 1-2. The distributed central market systems 1-1 and 1-2 that have received this exchange the collation results between them, and perform control so that sales and purchases do not overlap.
The market interlocking units 25-1 and 25-2 receive the collation results sent from the other central market systems 1-2 and 1-1, and the duplicated application is preliminarily converted into a market interlocking procedure as a market interlocking procedure storing unit 24-2. If registered in 1,24-2, this is executed to change the trading application data. This enables linkage between markets.

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

In this example, the central market system # 1 (1-
1) is located in Tokyo, Central Market System # 2 (1-2) is located in Osaka, and the Tokyo market and the Osaka market are held alternately and mutually transmit the contract results.

Here, the application status in the Tokyo market is shown in FIG.
It is assumed that the application status in the Osaka market is as shown in FIG.

In this example, Company E has applied for purchase in both markets in duplicate. In order to avoid duplication in advance, for example, the following procedure is registered in the market-linked procedure storage units 24-1 and 24-2 of both markets. (1) If Company E is established in the Tokyo market, the application for Company E in the Osaka market is canceled. (2) If Company E is established in the Osaka market, the application for Company E in the Tokyo market will be canceled.

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, it is assumed that the company A and the company E collate, and the transaction is established. The results are sent from the Tokyo market to the Osaka market.

In the Osaka market, the above procedure 1 is started by the market interlocking unit 25-2, and the purchase application data storage unit 12-
Delete the applicable data from 2 and cancel the application of E company in the Osaka market. As a result, there is no duplication in the Osaka market, since it is not a target of collation.

Next, an operation procedure of the central market system 1 of the present embodiment will be described with reference to FIG. FIG.
5 (a) is a procedure of the central market system 1-1,
(B) is a procedure of the central market system 1-2, and all procedures are the same. In addition, as mentioned above, the electronic market is repeatedly opened at the scheduled time,
In FIG. 25, the description for repetition is omitted, and only the procedure for one electronic market is shown.

Each of the central market systems 1-1 and 1-2 accepts an application from the client system 3 (steps S81-1 and S81-2).

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 S82-1).
82-2).

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

Steps S82-1, S8
Step 2-2 is repeatedly performed in response to receiving the application.

In each system, collation starts when the market opening time comes.

First, prior to the collation, if there is a notice of a contract for a duplicate application from other central market systems 1-2, 1-1 (steps S83-1 and S83-).
2) As described above, an interlocking process is performed based on the notification (steps S84-1 and S84-2). For example, cancel data corresponding to a contract made in another market.

[0285] Next, the matching sections 14-1 and 14-2 check the application for sale from the market client system 3 to determine the conclusion of the sale (steps S85-1 and S85-2).

As a result of the collation, if the contracted one is related to the duplicate application, a notice of the contract is sent to the other central market systems 1-2 and 1-1 related to the duplication (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 needed.

On the other hand, the market client system 3 on the selling side or the purchasing side, which intends to participate in the market, also transmits the information on the duplicate application to the central market system 1-
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. In addition, by receiving the notification that the transaction has not been completed, it is possible to know that the purpose of the application has been achieved by not receiving the notification that the transaction has been completed.

[0291] As described in the first embodiment, in the case where only a part of the application quantity may be closed,
Partial contracts may not be closed, or only partial contracts may be notified to other central market systems of the number of contracts that have been concluded, and other central market systems that have been notified may not be able to conclude contracts for the data. May be canceled (update the amount in the data), or only a part of the contract is notified and the number is notified to the other central market system. All the data may be cancelled.

In the present embodiment, the interlocking of two markets has been described. However, 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 an electronic market system according to the eighth embodiment of the present invention. FIG. 29 shows an example of the operation procedure of the central market system according to the present embodiment.

In the present embodiment, the electronic market system is composed of 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 participant's site.

[0296] This embodiment is a second system for controlling duplicate applications in a distributed electronic market. That is, in the seventh embodiment, the interlocking process for interlocking the plurality of overlapping markets by performing notification between the markets for the overlapping application to a plurality of markets is performed, but the interlocking process is performed in the present embodiment. Instead, an inquiry is made to the market client system 3 for a contract to be concluded, and the contract is concluded only when there is an approval response from both the purchasing side and the selling side.

[0297] Central market system 1-1 according to this embodiment.
Is a configuration in which a confirmation processing function for the market client system 3 is added to the configuration in 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 a confirmation unit 26-1.

The central market system 1-2 has the same configuration as that of the central market system 1-1.
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, and a confirmation unit 26-2.

Although the market client system 3 according to the present embodiment has a response unit 35, other configurations and operations are the same as those of the seventh embodiment.

In this embodiment, the central market system 1-
Each of 1, 1-2 checks with the target market client system 3 when checking the sales application and the purchase application. 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 whose sales have been collated, and respond to the market client systems. wait. The market client system 3 issues an approval response only once for a duplicate transaction, and sends a denial response for another transaction, thereby avoiding duplicate transactions.

Next, the interlocking process between markets 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 inquire of both market client systems 3 with respect to the result of the collation, and a transaction is established with respect to the confirmed one. .

[0303] 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), and the central market system 1-1 for opening the Osaka market. In step 2, a confirmation request message is sent to the corresponding market client system 3 (company C and company E).

As a result, a 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, any decision method may be used to determine which method of responding to the approval, but here, the company E arrives earlier. Acknowledgment shall be returned to those who have arrived, and a denial will be returned to those who arrive late. In this case, the confirmation request message from the Osaka market arrives earlier and returns approval to the Osaka market. In addition, as another determination method, for example, as described in the first embodiment, when there is a case where only a part of the application quantity is closed, an approval response is sent to the person who has made a larger quantity. Notification methods are also conceivable.

In the central market systems 1-1 and 1-2, a transaction is established only when an approval reply is obtained from both the purchasing side and the selling side market client system 3. Therefore, in this example, the E company in the Tokyo market Upon receiving the rejection, the transactions between Company A and Company E are cancelled. On the other hand, in the Osaka market, both companies C and E obtain approval responses and the transaction is completed. The matching is continuously performed in both the Tokyo market and the Osaka market. However, since there is no other matching unit, the matching is completed.

As described above, the market client system 3
Can avoid duplication.

Next, an operation procedure of the central market system 1 of the present embodiment will be described with reference to FIG. FIG.
9 (a) is a procedure of the central market system 1-1,
(B) is a procedure of the central market system 1-2, and all procedures are the same. In addition, as mentioned above, the electronic market is repeatedly opened at the scheduled time,
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 each receive an 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 S92-1).
92-2).

[0311] Steps S92-1, S9
Step 2-2 is repeatedly performed in response to receiving the application.

In each system, when the market opening time comes, the matching units 14-1 and 14-2 check the application for sale from the market client system 3 to determine the success of the sale (steps S93-1 and S93). −
2).

[0313] Next, as described above, the contracted products are confirmed with the target market client systems 3 on both the purchase side and the sales side, and a response of approval is received from both market client systems 3. Only when this is the case, the contract is concluded, otherwise the transaction is not established (steps S94-1 and S94-
2).

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

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

[0316] As described in the first embodiment,
Notification processing is performed as needed.

On the other hand, the market client system 3 on the selling side or the purchasing side that wants to participate in the market also sends information on the duplicate application to the central market system 1-
1, 1-2. And the central market system 1-
Wait for notification from 1, 1-2.

[0318] Each market client system 3 that has participated in the market can know that the purpose of the application has been achieved by receiving the notification that the transaction has been established. In addition, by receiving the notification that the transaction has not been completed, it is possible to know that the purpose of the application has been achieved by not receiving the notification that the transaction has been completed.

In the above description, all applications are checked. However, in the case of a duplicate application as in the seventh embodiment, this is indicated by the market client system 3.
From each of the central market systems 1-1 and 1-2 that make duplicate applications, and duplicate information is registered in each of the central market systems 1-1 and 1-2. Only the operation may be performed.

[0320] In this embodiment, the interlocking of two markets has been described, but it is also possible to interlock three or more markets.

(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. 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 participant's site.

[0324] In the present embodiment, a third method for controlling duplicate subscriptions in a distributed electronic market is provided. In the present embodiment, the market client system 3 that repeatedly participates in a plurality of markets creates a time-dependent procedure set to participate in one market at the same time, and transmits it to the central market systems 1-1 and 1-2. And the central market system 1-1, 1

The central market system 1-2 has the same configuration as that of the central market system 1-1.
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, and a time update unit 28-2. I have.

In the present embodiment, the market client system 3 that simultaneously participates in a plurality of markets registers the participation time in advance in a time-dependent procedure. 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 the time-dependent procedure is executed, thereby controlling the overlap by switching the overlapped applications every time.

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 collation start time and the collation end time in -2 are disclosed in advance. The central market systems 1-1 and 1-2 collate the sales applications applied 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 by the Osaka Market
2 shall be established. The comparison start time and the comparison end time of the Tokyo market are as shown in FIG. 32,
It is assumed that the collation start time and collation end time in the Osaka market are as shown in FIG.

[0331] The market client system 3 that intends to participate in both the Tokyo market and the Osaka market determines the optimal market participation method by examining the overlap of the market opening times of both markets. For example, when the respective collation start time and collation end time are as shown in FIGS. 32 and 33, there is no overlap at the same time if scheduling is performed as shown in FIG.

[0332] The market client system 3 obtains the 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 may be a procedural expression utilizing regularity. In addition,
The application data may be transmitted each time as in the first embodiment, may be transmitted as time-series data as in the second embodiment, or may be transmitted as a procedure as 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, the time update units 28-1 and 28-2 activate time-dependent procedures at each market opening time, and determine whether each market client system 3 participates. Is determined, and when participating, 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 dispersed markets can be obtained.

Next, an operation procedure of the central market systems 1-1 and 1-2 according to the present embodiment will be described with reference to FIG. In FIG. 31, description for repetition is omitted, and only a 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 upon receiving a time-dependent procedure, stores it in the time-dependent procedure storage unit 27-.
1 shall be stored.

In the central market system 1, if the opening time has come (or if the set time before the opening time has come), first, the time updating unit 28-1 will use 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 executes a time-dependent procedure to determine whether or not to participate in the market at the next time and obtain application data for participation (step S102). .

If it is determined 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 user re-enters the next market (step S103), if the obtained application data is for the purchaser (step S104), the updating unit 27-1 stores this in the purchase application data storage unit. 12-1 (step S105). If the obtained 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).

When the purchase application data and the sales application data are received without the notification of 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 or the like. It is stored in the sales application data storage unit 13-1.

Next, if all the data settings have been completed (if the setting has been completed before the opening time, the opening time has come), the matching processing / notification section 15-1 by the matching section 14-1 A notification process is performed (steps S108 and S108).
109).

[0343] Here, for a contract that has been concluded, the information is notified to the central market system 1-2 corresponding to another market described in the time-dependent procedure, and other central markets that have been notified are notified. The system 1-2 deletes all the corresponding information.

[0344] As described in the first embodiment, when only a part of the application quantity may be closed,
Partial contracts may not be closed, or only partial contracts may be notified to other central market systems of the number of contracts that have been concluded, and other central market systems that have been notified may not be able to conclude contracts for the data. May be canceled (update the quantity in the data) only for the part of the data corresponding to the quantity, or notified to other central market systems that only a part has been closed and the quantity is notified 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 contract is executed. Time-dependent procedure storage unit 16
-1 and move on to preparation for the next market opening.

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

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 also has a time-dependent procedure for making an application, and the central market system 1-1,1-
Notify 2. Then, the central market system 1-1,1-
Wait for notification from 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. In addition, by receiving the notification that the transaction has not been completed, it is possible to know that the purpose of the application has been achieved by not receiving the notification that the transaction has been completed.

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

(Tenth Embodiment) Next, a tenth embodiment of the present invention will be described.
Embodiment 0 will be described.

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

The electronic market system includes a central market system 101 that operates a market, a plurality of seller terminals 103 installed at sites of sellers participating in the market, and a plurality of terminals 103 installed at sites of buyers participating in the market. From the buyer-side terminal 102.

As a basic function of the central market system 101, at least one of two functions of providing information on a market and matching is provided. The provision of information on the market is a function of obtaining information on goods that the buyer wants to purchase from the seller and returning the information to the buyer. The matching function means that the buyer obtains information on the product that the buyer wants to purchase from the seller, and the central market system 101 performs matching with the buyer's specifications, selects the most suitable one and provisionally reserves it, This function notifies both buyers.

With regard to the information providing function relating to the market, the buyer's terminal verifies the buyer's specifications with the seller's information. In order to purchase the selected product, the buyer issues a purchase request based on the verification result (however, there is a time difference between providing information and issuing the purchase request, and the most suitable product is You may be unable to purchase due to lack of stock.) The central market system 101 relays the purchase request form to the seller side, and transmits a transaction completion notice to the buyer side when an acceptance message is received from the seller side.

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

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

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

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

The opening of the market is carried out on demand when the buyer accesses.

The central market system 101 transmits the quote request sent from the buyer terminal 102 to the buyer receiving unit 1.
11, the seller selection unit 112 searches and selects the seller who sells the corresponding product from the seller product file 114. Subsequently, the seller-side transmitting unit 113 transmits an estimate request to the selected seller and waits for a reply from the seller terminal 103.

The seller creates a quote for the corresponding product by a program stored in the terminal 103 or by manual intervention, and returns the quote to the central market system.

In the central market system 101, upon receiving the quotations returned from the seller by the seller-side receiving unit 115, the buyers activate the buyer-side transmitting unit 116 and return them to the corresponding buyer.

The above processing is performed within a predetermined time. That is, if there is no reply from the seller within a certain period of time, it is assumed that there is no reply and the process is continued. This guarantees that the buyer will always receive a response within a certain period of time after issuing the quote request form, greatly improving the work efficiency as compared to a market opened at a predetermined time.

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

In the central market system 101, when a purchase request is received by the buyer-side receiving unit 111, the purchase request is transmitted to the corresponding seller terminal by the seller-side transmitting unit 113.

When the seller terminal 103 receives the purchase request form, it checks the stock / delivery date, etc.
return any of the rejects to the central market system 101.

The central market system 101 considers that the transaction has been established by receiving the accept from the seller terminal 103, notifies both the corresponding buyer terminal 102 and the seller terminal 103 of the corresponding transaction, and also performs the lighting for the transaction. Keep a record.

[0369] The central market system 101 is the seller terminal 10
If reject is received from 3, the transaction is not established,
Buyer-side terminal 10 corresponding to buyer-side transmitting section 116
2 is rejected.

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

Here, three buyer terminals (A, B,
C) and three seller terminals (X, Y, Z) will be described. The products handled by this market are "apples" and "oranges". Assume that the selling price and stock of “apple” of companies X, Y, and Z are as shown in FIG. 37, and that the selling price and stock of “orange” are as shown in FIG.

From the buyer's terminal 102 of Company A, tangerines 1
Assume that 00 quote requests have been transmitted 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 commodity file 114 and obtains the corresponding seller. Here, it is assumed that information is stored in the seller commodity file 114 as shown in FIG.

From this, the seller transmitting section 113 knows that the sellers handling oranges are three companies X, Y, and Z.
Send the quote request form of company A to companies X, Y and Z and wait for a reply.

In the case of this example, the company X does not reply because the stock is insufficient. Company Y returns a quote of 120 yen and Company Z returns a quote of 100 yen within a certain period of time.

The central market system 101 summarizes the result, and sends the result to the company A by the buyer-side transmitting unit 116.
Company Y replies information of 120 yen and company Z 100 yen within a certain time.

[0377] Upon receipt of the request, the terminal 102 on the buyer side of company A selects company Z automatically or manually, for example, because company Z is cheaper, and issues a purchase request form to company Z within a certain period of time. It is sent to the central market system 101.

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

Upon receiving the purchase request form, Company Z checks the inventory, determines accept / reject, and responds to central market system 101.

The central market system 101 was obtained from Company Z by ac
Upon receipt of the cept, the transaction is considered to be completed, the company A is notified, and a record for certifying the transaction is stored.

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.
A second embodiment will be described.

FIG. 41 shows the configuration of the electronic market system according to the present embodiment. The electronic market system includes a central market system 101 that operates a market, a plurality of seller terminals 103 installed at sites of sellers participating in the market, and a plurality of buyers installed at sites of buyers participating in the market. It comprises a terminal 102. This embodiment provides a matching function.

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

The opening of the market is carried out on demand when the buyer accesses. However, it is also possible to collectively handle a plurality of buyer-side accesses arriving within a certain time. When handled collectively in this way, it becomes possible to incorporate a function of selecting a buyer on the seller side.

The central market system 101 receives the quote request sent from the buyer's terminal 102, and
11 and collectively transmit them to the seller selection unit 112 within a predetermined time, and search and select the seller who sells the corresponding product from the seller product file 114. Subsequently, the seller-side transmitting unit 113 transmits an estimate request to the selected seller and waits for a reply from the seller terminal.

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

In the central market system 101, when the seller receiving section 115 receives the quote returned from the seller, the matching section 117 performs matching. The matching unit 117 registers a pair of the seller and the buyer most suitable as a result of the matching as a tentative reservation, and
At 15, each is returned to the corresponding buyer.

[0389] Upon receiving the returned temporary reservation form, the buyer issues a purchase request form within a predetermined time and transmits it to the central market system 101.

In the central market system 101, if a purchase request is received by the buyer-side receiving unit 111, it is regarded that a transaction has been established, and the corresponding buyer-side terminal 102 and seller-side terminal 1
03 and keep a record for the lighting of the transaction. If the purchase request is not transmitted from the buyer terminal 103 within a certain period of time, it is regarded that the transaction has not been completed, and the provisional reservation is canceled.

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

With regard to the products to be handled and the products of the seller, the eleventh embodiment, that is, FIGS.
Same as In this embodiment, it is assumed that the buyer specifies the purchase conditions for verification in the quote request form.

A request for quote is transmitted from the buyer's terminal 102 of Company A. In this request for quote, 50 apples,
It is assumed that a purchase condition that the price is 100 yen or less is presented. Similarly, from Company B, 50 apples and the price is 120
Suppose that a purchase condition of less than yen is presented.

In the central market system 101, this information is passed to the matching unit 118 by the buyer-side receiving unit 111. The collating unit 118 learns from the seller commodity file 114 that the handling of the apple is X, Y company, sends the purchase conditions of A company and B company to X, Y company, and waits for a reply.

It is assumed that Company X and Company Y prepare the following responses to the purchase conditions of Company A and Company B. However, it is assumed that the selling price of the apple of Y company is 120 yen, and since the purchase condition of A company is not satisfied, there is no reply from Y company to A company. Reply from Company X to Company A: Price 100 yen, 50 pieces Reply from Company X to Company B: Price 100 yen, 50 pieces Reply from Company Y to Company A: reject Response from Company Y to Company B : Price 120 yen, 50 pieces The seller-side receiving unit 115 of the central market system 101 has X
When this information is received from the company Y and the company Y, the information is passed to the collation unit 117 and collation is started. In this case, since the stock of Company X is 50 pieces, it cannot be sold to both Company A and Company B.

The collation method in the collation unit 117 may be various, but here, a method is adopted in which sellers are randomly arranged and matching is performed in that order as long as stock is available. FIG. 42 shows an example of the procedure of the collation processing.

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

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

At step S112, buyers are arranged in order. As the first case, b (1) is Company A, b (2)
Is described as B company.

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

In step S114, since the answer to company A is only company X, step S115 is passed and company A and company X are collated by matching in step S116, and this is registered as a temporary reservation.

Next, the stock of company X is adjusted in step S117. Since the stock of Company X is 50 pieces, the sale to Company A causes the stock of Company X to be out of stock, and the sale to Company X → Company B becomes impossible.
Is removed from p.

The processing of Company A is completed as described above, and then b (2)
Move to the processing of Company B.

Since the answer of (Company X, Company B) has been removed from p, the answer to Company B is Y in Step S114.
Company only.

[0405] In step S116, Company B and Company Y match and register this as a provisional reservation. Similarly Y
Company has 100 units in stock, so 50 units sold to Company B
The number is reduced to 50.

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

On the other hand, if the order in b is B company and A company (b (1) is B company and b (2) is A company),
In step S114, the answer to company B is both company X and company Y. In step S116, company X and company X collate because the company X is lower in the matching, and this is registered as a tentative reservation.

[0408] In step S117, the stock of Company X is adjusted. Company X is sold out to Company B, and becomes out of stock.
Company A) is removed from p.

Next, the process moves to the company A.
In step 4, the answer to company A is empty, and the check in step S115 ends for company A without matching.

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

FIG. 43 shows the configuration of the electronic market system according to the present embodiment. The electronic market system includes a central market system 101 that operates a market, a plurality of seller terminals 103 installed at sites of sellers participating in the market, and a plurality of buyers installed at sites of buyers participating in the market. It comprises a terminal 102.

[0412] In the eleventh and twelfth embodiments, each time there is an access to the quote request from the buyer terminal, communication regarding the quote or purchase request is performed with the corresponding seller terminal. So, Central Market System 1
01, and stores information on sales such as price, stock, delivery date, etc. of each merchandise in the merchandise file 114 in the central market system without communication with each seller terminal 103 each time. 101.

As in the twelfth embodiment, the central market system 101 receives the quote request sent from the buyer terminal within a certain period of time by the buyer receiving unit 111 and collectively sends them to the matching unit 118. introduce. The matching unit 118 searches the seller product file 114 and obtains sales information of the corresponding product.
Matching with the specification of the buyer-side quote request form received is performed in a procedure as in the twelfth embodiment, for example.
The matching unit 118 registers the pair of the seller and the buyer most suitable as a result of the matching as a tentative reservation, and the buyer-side transmitting unit 113 returns the pair to the corresponding buyer.

[0414] Upon receiving the returned temporary reservation form, the buyer issues a purchase request form within a predetermined time and transmits it to the central market system 101. In the central market system 101, if a purchase request is received by the buyer-side receiving unit 111, it is regarded that the transaction has been completed, and the corresponding buyer terminal 102 and seller terminal 103 are notified to both, and a record for certifying the transaction is provided. Save. If the purchase request is not transmitted from the buyer terminal 102 within a certain period of time, it is regarded that the transaction has failed, and the provisional reservation is canceled.

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

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

FIG. 44 shows the configuration of the electronic market system according to the present embodiment. The electronic market system includes a central market system 101 that operates a market, a plurality of seller terminals 103 installed at sites of sellers participating in the market, and a plurality of buyers installed at sites of buyers participating in the market. It comprises a terminal 102. This embodiment provides a matching function.

[0418] First, the seller registers a purchase quantity-unit price correspondence table 1140 in the seller product file 114 of the product handled by the seller. The purchase number-unit price correspondence table records the number of products sold and the unit price at that time. Normally, the unit price is often set low for a party who purchases a large amount of products, so the purchase quantity-unit price correspondence table 1140
May have multiple entries. Also, unit prices and units sold may change depending on the seller's inventory,
In this case, the purchase quantity-unit price correspondence table 1140 is updated each time. The information in the seller product file 114 and the purchase quantity-unit price correspondence table 1140 are corrected through the correction unit 119.

[0419] Upon receiving an estimate request from the buyer, the estimate request division unit 120 refers to the purchase quantity-unit price correspondence table 1140 of each seller who sells an individual product so that the overall purchase price is the lowest. Next, determine which sellers and how many orders to place. Accordingly, the estimate request dividing unit 120 divides the estimate request and transmits the divided estimate request to each seller.
The estimation request splitting unit 120 waits until the estimate request is received for all of the split estimation requests, and returns them all together to the buyer.

Hereinafter, the present embodiment will be described using a specific example.

[0421] Assume that buyer A wants to purchase 100 melons. Two sellers X on "Melon"
Company and company Y, and the seller product file 114 includes FIG.
It is assumed that a purchase quantity-unit price correspondence table for Company X as shown in FIG. 5 and a purchase quantity-unit price correspondence table for Company Y as shown in FIG. 46 are registered. It should be noted that the company Y has limited stock and cannot sell more than 80 pieces.

The case with the lowest unit price is a case where 40 or more pieces are purchased from Company Y. However, Buyer A tries to purchase 100 pieces, while Company Y can only sell up to 80 pieces. You need to buy it separately.

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 indicates the purchase amount, and the horizontal axis indicates the number of purchases from Y company. In other words, the left end is melon 100
The case where all the melons are purchased from the company X, the right end shows the case where the whole 100 melons are purchased from the company Y (however, this cannot be realized because only 80 can be purchased from the company Y). The part shown in bold practice is the purchase price,
Since the purchase price varies discontinuously with the sales quantity at 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 estimation request division unit 120.

First, the estimation request division unit 120 checks the correspondence table 1140 of the purchase quantity-unit price of all sold melons, and lists the candidates of the optimal combination of the sales quantity (step S121). In this example, seller X
Is 50, and the number of purchases at which the unit price of the seller Y changes is 80. Therefore, the optimal purchase number candidates are 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 following result is obtained. (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 is understood that the cost is lowest when 50 pieces are respectively purchased from X company and Y company. Therefore, in the case of the present example, a combination of (X, Y) = (50, 50) is determined (step S123).

[0426] Therefore, the estimation request dividing unit 120
Is divided into a request for estimating 50 melons for X and a request for estimating 50 melons for Y, and transmitting the request to companies X and Y (step S124).

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

The function related to the estimation request division can be implemented in combination with any of the tenth to thirteenth embodiments.

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

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

In the present embodiment, first, a transaction basic number is added to a quote request form on the buyer side and managed. Two forms are shown as examples of this processing.

FIG. 49 shows the first mode. In this embodiment, an estimate request form is sent from the buyer-side terminal 102 to the buyer-side receiver 111 of the central market system 101. Upon receiving the quote request form 160, the buyer-side receiving section 111 acquires the transaction basic number from the transaction basic number assignment section 151, adds the transaction basic number to the quote request form, and proceeds as a quote basic request-added quote request 161.

FIG. 50 shows a second mode. In this embodiment, a transaction basic number issuance request is sent from the buyer terminal 102 to the buyer receiver 111 of the central market system 101. The buyer-side receiving section 111 acquires the basic transaction number from the basic transaction information allocating section 151, and transmits the basic transaction number to the buyer-side terminal 102 via the buyer-side transmitting section 116. The buyer's terminal 102 adds the transaction basic number to the quote request and returns it to the central market system 10 as a transaction basic numbered quote request 162.
Send to 1.

The difference between the first mode and the second mode is that in the second mode, the basic transaction number can be recorded at the time when the buyer terminal 102 issues an estimate request.

Next, FIG. 51 shows a configuration example in the case where the record of the transaction process is recorded in the market log file by the central market system 101. Here, it is assumed that, in the first or second embodiment, the quote request, the quote, and the purchase request have a basic transaction number.

In the central market system 101, upon receiving the quote request form from the buyer terminal 102, the
0 to the twelfth embodiment, the seller-side terminal 1
Send to 03. At that time, the transaction process recording unit 152 connects the copy of the quote request form to the link corresponding to the transaction basic number in the market log file 153.

[0437] In the central market system 101, upon receiving the quote from the seller terminal 103, the market log file 1 is created based on the transaction basic number added to the quote.
A corresponding estimate request form is searched from 53. Then, it is checked whether the items described in the quote, such as the product name, the number, the price, the delivery date, and the like, match the conditions of the items described in the quote request.

[0438] If they do not match, predetermined processing such as invalidating the quote or sending a warning message to the seller terminal 103 and returning the quote is performed.

[0439] If the items described in the quote match the items described in the quote request, the quote is sent to the terminal of the buyer according to the procedures of the tenth to twelfth embodiments. At that time, the transaction process recording unit 152 may link a copy of the quote to the link corresponding to the transaction basic number in the market log file 153.

[0440] In the central market system 101, upon receiving the purchase request form from the buyer terminal 102, the corresponding quote from the market log file 152 is obtained based on the transaction basic number added to the quote and the seller's company name. Search for.

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

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

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

[0485] When transmitting information to the central market system 1001 on the client side, first, transmission data created by the terminal 1002 is transmitted to the device 1020.

[0486] In the device 1020, a clock 1025, an ID 1024 unique to the device, 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 transferred to the terminal 1002 and transmitted.

The device 10 also determines whether the transmission was successful.
20 is stored in the recording device 1026. 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 referred to, has a sufficient bit width, and becomes 0 again if the serial number overflows.

When information is received from the central market system 1001 on the client side, the data received by the terminal 1002 is first sent to the device 1020. Since this data is encrypted, the terminal 1002 cannot know the 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 transmitted to the decoder 1
028 and return it to terminal 1002. The terminal 1002 uses the data that has been plaintext by the decoding of the decoder 1028.

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

Here, it is conceivable that the clock 1015 of the central market system 1001 and the clock 1025 of the device 1020 on the client side do not always match or a deviation occurs. Therefore, Central Market System 1
001 to the clock 1 in the client device 1020
025 is set so that the time can be set. Alternatively, the time of the clock 1025 in the client device 1020 is read from the central market system 1001 and the time difference between the two clocks is recorded, and the clock of the other party and the own clock are logically synchronized. At this time, the client also reads the time of the clock 1025 of the central market system 1001 and shifts both clocks (or the central market system 1001).
The time of the first clock 1025) is recorded in the storage device 1026 in the device 1020.

Also, the clock is adjusted or the time of the other party's clock is read at regular or random time or immediately before or after the communication, and the time is physically or logically synchronized.

By doing so, it is possible to monitor that the time on the client side or the central market system 1001 side is not normal due to intentional or accident. For example, an abnormality is detected when the time difference between the two clocks suddenly increases.

It is preferable that the encoder 1023 and the decoder 1028 use different keys. In this case, the data encoded by the encoder 1023 cannot be restored by the decoder 1028. Further, the data decoded by the decoder 1028 cannot be restored by the encoder 1023.

[0496] The information in the storage device 1026 in the device 1020 has a function of being written to the storage device in the terminal 1002 before overflowing. The written data cannot be decrypted or modified for the above reasons. Further, since the encrypted data includes the serial number, the data cannot be deleted without leaving any trace.

[0497] Neither the client terminal 1002 nor the central market system 1001 alone can decode this data. This information can be obtained from public information such as courts and passwords managed by the Central Market System and their ICs.
The contents can be read out for the first time by using both the password managed by the side using the card and the password. Further, a password of an electronic notary or a certificate authority may be required as the third password.

It is conceivable that the device 1020 is constituted by an IC card. Moreover, the PCMCIA specification widely used in personal computers and the like may be used. In addition, any type of device having an interface with any computer system such as a personal computer type terminal system may be used.

[0499] Each of the above functions can also be realized as software. Further, the present invention can be embodied as a machine-readable medium storing a program for causing a computer to execute the above-described procedures or means.

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

[0501]

According to the present invention, by digitizing the market mechanism, it is possible to realize an effective electronic market which enables smooth operation and can flexibly respond to the demands of participants. In particular, market participants can participate in the market even if they are geographically distant, and by incorporating strategies according to market conditions as procedures, labor savings can be made. And participate in a decentralized market at the same time, thereby increasing the convenience of transactions.

[0502] Further, according to the present invention, by devising the computerization of the market mechanism, market participants can participate in the market even if they are geographically distant, and on-demand acquisition of market information and automation of verification can be performed. It becomes possible.

[0503] In addition, the market operator can open a market electronically, and thus can quickly and efficiently operate an equal market.
