Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a transaction support facility for supporting, via an apparatus system, a commercial transaction between a provider providing goods or services and a buyer receiving the provision of the goods or services.
[0002]
[Prior art]
2. Description of the Related Art With the development of communication systems and devices represented by the Internet, electronic commerce using the data properties and real-time properties of the Internet has recently become popular.
[0003]
As such, there is an auction system in which a buyer presents a purchase price for one product or service using the Internet, and a product that presents the highest price can purchase the product.
[0004]
In a general electronic commerce transaction other than an auction, there is a transaction mode in which a seller presents a selling price for a product or a service, and the buyer presents a buying price using the Internet, and the two parties negotiate the price. (For example, see Patent Document 1)
[0005]
[Patent Document 1] JP-A-2002-259662 (page 11, FIG. 8)
[0006]
[Problems to be solved by the invention]
However, both of them, as a matter of course in the conventional business practice, match in that a transaction is established only when the offered prices of the seller and the buyer match (although brokerage fees may be deducted). In other words, unless the price presented by the buyer is at least equal to or greater than the price presented by the seller, the seller will be damaged and the transaction will not be established.
[0007]
Here, the difference between the price presented by the buyer and the price presented by the seller may be negative in anticipation of the subsequent transaction, in other words, it may be possible to establish a transaction that damages the seller. Determining whether the minute difference can be recouped is very difficult, even for an experienced seller. Furthermore, in the case of automatically closing a transaction on the Internet, etc., it is extremely difficult to determine on what basis a transaction that will result in a negative transaction will be completed, and there is a risk that the transaction will end up in the red. High.
[0008]
Therefore, such a transaction is not completed, and the closing rate cannot be increased.
[0009]
[Means for Solving the Problems]
That is, as shown in FIG. 1, the present invention includes a purchase request data receiving means for receiving purchase request data including at least data relating to price, and a sales request data receiving means for receiving sales request data including at least data relating to price. A difference calculating means for calculating a difference between the desired purchase price specified by the desired purchase data and the desired sales price specified by the desired sales data corresponding to the content of the desired purchase data; and First output means for outputting a contractable signal to the effect that a trade can be made when it is shown, compensation reserve certifying means for certifying the positive difference as a reserve reserve that can be deposited, Replenishment reserve storage means for storing possible replenishment reserves as data, and replenishment reserves deducted from the replenishment reserve storage means Limit management means for managing the limit in the case where the difference is a negative value, and compensation determining means for determining whether or not the amount corresponding to the difference can be compensated within the range of the limit when the difference indicates a negative value. And a second output means for outputting a contractable signal indicating that a trade can be established when the compensation judgment means judges that compensation is possible.
[0010]
In order to realize the present invention as a system, there are cases where the system is configured only with a stand-alone device, and cases where the system is configured with a host device and a terminal device connected thereto via a communication network such as the Internet. is there.
[0011]
Here, the “purchase desired price” includes not only a price having no width, such as 100 yen or 1000 yen, but also includes a price having a width of 100 yen or more and 200 yen or less. The same applies to the "sale price". “Managing the limit amount” includes setting a predetermined limit and calculating or changing the limit amount. Further, "output a contractable signal" here means, for example, outputting to a means for controlling a contract, displaying on a screen such as a display, printing on a printer, fax, Output in various forms, such as sending to a particular device.
[0012]
In such a case, it is possible to close the transaction not only when the desired price is higher than the desired price but also when the desired price is lower than the desired price and the difference is negative. Since it is possible, it is possible to achieve a transaction which cannot be considered in the conventional transaction form and dramatically improve the transaction closing rate. Further, it is possible to avoid a risk that has been a drawback in the case of establishing a transaction showing a negative value in the related art, and to surely perform a positive commercial transaction in the total transaction. In other words, while guaranteeing that the total difference will not be negative at all times, it will also be able to close deals that could not normally be traded, break the difficulties and scarcity of deals, and automatically avoid damages As a result, the speed at which a transaction is completed can be secured.
[0013]
Further, in order to accurately grasp the replenishment reserve and enhance the stability of the transaction, as shown in FIGS. 2 and 4, the contract is executed based on the contractable signal output from the first output means. If it is established, it performs data processing for storing the replenishment reserve recognized by the replenishment reserve recognition means in the replenishment reserve storage means, and executes the contract based on the contractable signal output from the second output means. It is preferable to include compensation data processing means for performing data processing for withdrawing the compensation reserve from the compensation reserve storage means in order to compensate for the difference indicating a negative value when is established.
[0014]
Further, in order to automatically detect a provided product corresponding to the content of the purchase desire data and to quickly and simply execute a transaction, as shown in FIGS. 3 and 4, a database storing provided products is used. It is conceivable to provide a search command means for outputting a search command signal indicating that a search should be performed, and to provide sales request data receiving means for receiving sales request data on provided products returned in response to the search command signal.
[0015]
In addition, the limit for withdrawing the reserve from the reserve reserve storage means is managed based on whether a value determined based on the required replenishment exceeds a threshold calculated from past transaction results, and the replenishment reserve is managed. This avoids the danger that the money will be used up in a short period of time and cannot be compensated for in the next transaction, and it will be possible to determine a reasonable limit for continuing many transactions.
[0016]
In addition, by managing the maximum amount of withdrawal reserves from this replenishment reserve storage means according to the past trading conditions of the customer and the activity of the trading market, it is possible to close transactions in anticipation of future profits It can be.
[0017]
Further, for example, when the balance of the reserve reserve stored in the reserve reserve storage means has decreased below a certain rate or when the balance has shown a rapid decrease rate, the balance of the reserve reserve is determined according to the balance of the reserve reserve. By managing the limit by changing the amount, the continuity of the system can be maintained and stable operation can be realized.
[0018]
In addition, by managing the limit amount in consideration of the reserve for cancellation in order to respond to the case where the execution of the trade is canceled, even if the contract with a positive difference is cancelled, it will be damaged. A supplementary system can be constructed.
[0019]
A configuration for calculating a difference between a total desired purchase price for a plurality of products or services and a total desired sell price for a plurality of products or services specified by the desired sales data corresponding to the content of the desired purchase data; It is also possible to do. As a result, whether or not compensation is possible is considered based on the total price without depending on the price of each product or service. For example, if the difference between the desired purchase price and the desired sale price of each product or service is calculated, compensation is not possible. Even if it is impossible to make a contract, it is possible to make a contract by mutually complementing a plurality of products or services, and it is possible to dramatically improve the transaction closing rate.
[0020]

Then, it is connected in a state where it can communicate with the buyer terminal device P1 and circulates through a plurality of predetermined buyer terminal devices P1 to automatically detect schedule data including at least data relating to a date.
[0038]
The schedule data receiving means 21B receives schedule data detected using the automatic detecting means 21A. For example, the schedule data receiving means 21B stores data relating to a date and schedules such as "meeting" and "Fukuoka" described in the date column. Accept the data shown.
[0039]
The arrangement management means 21C has a function of managing whether or not arrangements for commodities necessary for executing the schedule received by the schedule data receiving means 21B have already been made. Specifically, it has a timer or the like (not shown), and executes a schedule included in the schedule data when a predetermined time is reached or when the schedule data is received by the schedule data receiving unit 21B. Check if the necessary products have been arranged above, and if not, start to arrange. For each schedule, there is a function of managing the arrangement state for each schedule by storing data such as whether the arrangement state is an unarranged state or an arrangement completed state. It should be noted that if the purchaser indicates that the arrangement is unnecessary, the arrangement may not be made thereafter.
[0040]
The planning means 21D has a function of creating a plan required to execute the schedule received by the schedule receiving means 21B. In the present embodiment, a plurality of plans are created based on the contents included in the schedule data, the plan data stored in the data storage unit 21G described later, and the purchaser data. Specifically, it is assumed that the purpose is a meeting, the start time of the meeting is 13:00, the end time is about 17:00, and the venue is Fukuoka in the schedule data. Then, first, plan data relating to the movement is read. At this time, it is defined that the travel plan, the departure place, the departure time, the arrival place, and the arrival time must be defined as the travel plan data. Further, when the purpose is a meeting, various conditions, such as arriving 20 minutes before the start and setting the departure place to a company, are set in advance. Therefore, when the meeting start time is received as 13:00, the arrival time is automatically converted from the start time, and a plan to arrive at the venue at 12:40 is created. Further, since a company address or the like is stored in advance as purchaser data, a plan is created by automatically applying the purchaser's company address to the place of departure. Then, a plan is created by filling in other items that are not automatically determined, for example, conditions desired by the buyer, such as transportation means and departure time, by using question data creation means 21F described later.
[0041]
The route search means 21E searches for a route from the departure place to the arrival place, and has a function of converting travel means and required time in addition to various routes.
[0042]
The question data creating means 21F has a function of creating question data for deriving a purchase desired condition of a product required for the schedule based on the condition derived from the schedule data. That is, in order to derive data necessary for planning using the planning means 21D, for example, conditions necessary for arranging transportation and accommodation facilities, "Where is the destination?" Create question data that asks "What is your desired arrival time?""What is your desired departure time?""What is your purpose?""Where is your departure place?" . In addition, if the schedule data contains a character string that seems to be a destination such as “Fukuoka”, create question data that prompts confirmation such as “Is the destination in Fukuoka?” Is also conceivable. It is also conceivable to create question data for presenting a product predicted based on a past purchase history. Note that, in the present embodiment, although it is configured such that it can be selected from the predetermined question data stored in the data storage unit 21G, it may be created sequentially.
[0043]
As shown in FIG. 8, the data storage unit 21G stores the buyer data 211G, the desired purchase condition data 212G, the question data 213G, the plan data 214G, the purchase condition data 215G, etc. in various areas. More specifically, the buyer data 211G stores the buyer's personal information such as a company address, a home address, and a telephone number as name data and location data, as well as the purchase history of the buyer based on the buyer identifier. I do. Further, as the desired purchase condition data 212G, various data that can be the desired purchase conditions, such as a destination, a departure place, a departure time, an arrival time, transportation, a purpose, and a desired purchase price, are stored. Furthermore, as the question data 213G, "Where is the destination?""What is the desired arrival time?""What is the desired departure time?""What is the purpose?""Where is the departure place?" Data for deriving desired purchase conditions, such as "What is the desired purchase price?", Are stored. Further, the plan data 214G is defined to define conditions required for a plan for executing a schedule, for example, a means of transportation, a departure place, a departure time, an arrival place, an arrival time, and the like. Further, when the purpose is a meeting, various conditions, such as arriving 20 minutes before or a departure place as a company, are stored as plan data. The purchase condition data 215G includes conditions necessary for actually arranging products, for example, departure time, departure place, name, age, gender, airline, which are conditions required for purchasing a flight ticket. Necessary items such as destination, arrival time, flight number, desired seat, and payment method are stored for each product. In addition, the purchase condition data 215 stores general contents necessary for purchase from any seller, as well as different contents for each seller (site). It has a configuration that can be used.
[0044]
The question data output means 21H has a function of outputting question data created using the question data creation means 21C to the buyer terminal device P1.
[0045]
The answer data receiving means 21I receives answer data from the buyer for the question data. In the present embodiment, response data is received by receiving response data from the buyer terminal device P1.
[0046]
The purchase desire data creating means 21J creates purchase desire data relating to a product having the purchase desire conditions and the like extracted from the answer data. For example, as the purchase desire conditions, "departure place" is set to "Tokyo", " When the destination is received as "Fukuoka" and the desired purchase price is received as "40000 yen", purchase request data is created by using an airplane ticket that satisfies the desired purchase conditions as a product. If there is a possibility of accommodation, purchase request data that satisfies an accommodation plan for reserving accommodation facilities is created. As shown in FIG. 16 of the present embodiment, when a plurality of products are required to execute the schedule included in the schedule data, a series of product groups are selected, and a plurality of products included in the product group are selected. Create purchase desire data for the product.
[0047]
The desired purchase data output means 21K outputs the desired purchase data created by the use of the desired purchase data creation means 21J to the desired purchase data receiving means 22A of the sales support apparatus SRV2 described later.
[0048]
The purchase condition generating means 21L has a function of generating conditions required for actually purchasing a product. Specifically, the conditions listed as the purchase condition data 215G, for example, the conditions required when purchasing an airline ticket, such as departure time, departure place, name, age, gender, airline, destination, Arrival time, flight number, desired seat, payment method, etc. In addition to general contents required for purchase from any seller, different conditions must be satisfied for each seller terminal device P2 (site). The necessary conditions are heard from the purchaser using the above-described question data creating means 21F and the like, and the necessary purchase conditions are generated.
[0049]
The sales support device SRV2 includes a purchase request data receiving unit 22A, a search command unit 22B, a sales request data receiving unit 22C, a difference calculating unit 22D, a first output unit 22E, a supplementary reserve certifying unit 22F, and a supplementary reserve storage unit 22G. It has at least functions as compensation limit management means 22H, compensation determination means 22I, second output means 22J, compensation data processing means 22K, and contract control means 22L.
[0050]
More specifically, the purchase request data receiving means 22A receives purchase request data including at least data on prices. When the purchase desire data is composed of a commodity group having a plurality of commodities, the total amount is received as price-related data. Needless to say, a desired purchase price may be received for each product. In the present embodiment, it receives the desired purchase price data, desired purchase product data, temporary hold data, temporary hold cancel data, purchase confirmation data, purchase cancel data, and the like transmitted from the buyer terminal device P1. The input may be received by receiving data from another device, or may be received by a recording medium such as a CD-ROM or a DVD-ROM. Furthermore, it is also possible to receive the information from the buyer Y by facsimile or mail, and to input the received information directly to the server SRV.
[0051]
The search command unit 22B has a function of outputting a search command signal indicating that a provided product corresponding to the content of the purchase desire data should be searched from a product database storing product data. If a plurality of products to be searched are required to execute the schedule, a search command signal is output for all the products included in the product group. Specifically, sales desire data relating to a product desired by the buyer is searched from a product DB (database) 3B of the various seller-side devices P2 via a product search device SRV3 described later. Although the merchandise DB is provided in the seller terminal device P2 in the present embodiment, it may be provided in the server device SRV.
[0052]
The sales request data receiving means 22C receives sales request data on the provided product returned in response to the search command signal. In the present embodiment, the selling price data, the selling product data, and the like transmitted from the seller terminal device P2 are received. Note that, similarly to the purchase request data receiving unit 22A, the request may be received by a recording medium such as a CD-ROM or a DVD-ROM. Further, it is also possible to receive the information by facsimile or mail from the seller X, and to input the received information directly to the server SRV by the facility operator or the like.
[0053]
The difference calculating means 22D has a function of calculating a difference between the desired purchase price specified by the desired purchase data and the desired sales price specified by the desired sales data corresponding to the content of the desired purchase data. Specifically, the difference is calculated by subtracting the desired selling price from the desired purchasing price. In the case of a product group having a plurality of products, the difference between the total purchase price of each product and the total sale price of each product is calculated.
[0054]
When the difference calculated by the difference calculating means 22D indicates a positive value, that is, when the desired purchase price exceeds the desired sale price, the first output means 22E provides a contractable signal indicating that the trade can be established. Is output.
[0055]
Here, the "executable signal" refers to a signal indicating that a transaction can be established at the desired purchase price and the desired sale price.
[0056]
When the difference calculated by the difference calculation means 22D indicates a positive value, that is, when the desired purchase price exceeds the desired sale price, the replenishment reserve recognition means 22F recognizes the difference as a replenishment reserve that can be accumulated. To do. The approved replenishment reserve is stored as a replenishment reserve in a replenishment reserve storage unit 22G, which will be described later, at a timing according to a predetermined rule. In the present embodiment, when a product is consumed, it is accumulated as a supplementary reserve.
[0057]
The replenishment reserve storage means 22G is for accumulating the replenishable reserves as data.
[0058]
The replenishment limit management means 22H has a function of managing the limit when the replenishment reserve is withdrawn from the replenishment reserve storage means. Specifically, when the result calculated by the difference calculation means 22D indicates a negative value, a rule for withdrawing the replenishment reserve from the replenishment reserve storage means 22G is determined and the limit is managed. . In the present embodiment, the limit is managed based on the priority score of compensation determined according to the compensation formula defined below based on the necessary compensation amount. More specifically, the compensation priority score is calculated by a necessary compensation amount (difference indicating a negative value) / (purchase desired price + sale desired price). For example, if the desired purchase price is 100 yen and the desired sale price is 120 yen, the difference (required replacement amount) is minus 20 yen. Therefore, the priority score is 20/220 ≒ 0.09. This priority score is always larger than 0 and equal to or smaller than 1, and is an index by which the smaller this value is, the higher the priority is. Then, a threshold of the priority score virtually obtained from the past transaction results is derived, and the limit in the current compensation is managed based on whether or not the current priority score exceeds the threshold of the priority score.
[0059]
As a method of calculating the threshold value of the priority value score, first, the priority value score is calculated based on a certain number of transaction results in the past, specifically, transaction results selected based on the number of transactions, the transaction period, the total transaction volume, and the like. This transaction result includes not only contracts that were actually executed but also contracts that were not executed due to a negative margin. In other words, all pairs of the sell data and the buy data in a certain period or the like are once matched, and the difference between each pair is calculated. Then, sorting is performed in the descending order of difference (indicating a positive value).
[0060]
On the other hand, the income (total of commissions + total profit) generated in the matching is calculated. Here, for example, if a certain rule such as not converting 20% of the profit as a reserve for cancellation in order to cope with a case where the execution of the trade is canceled is set, the retained amount according to the rule is set as described above. It could be deducted from the total income. At this time, a limit value that can be compensated by the supplementary reserve stored in the supplementary reserve storage unit 22G is derived, and the priority value score of the trading pair that becomes the limit value is set as the threshold.
[0061]
Further, if it is desired to accurately calculate a priority value score larger than the priority value score which has become the limit value by the above-described calculation method as a threshold value within a range in which compensation is possible, the compensation reserve money storage means 22G is stored. It is conceivable to subtract the compensation amount in the priority value score that has become the limit value from the compensation reserve and derive a priority value score that becomes a limit when the difference is used for compensation.
[0062]
Specifically, it is assumed that the compensation amount at the priority value score 0.5 is 10500 yen. At that time, the replenishment reserve stored in the replenishment reserve storage unit 22G is 10700 yen, and if the next transaction is to be established, the priority score is 0.7 and the replenishment amount is required to be 10750 yen. Then, the priority value score serving as the limit value is 0.5. However, in this case, when the compensation amount in the priority value score which has become the limit value is subtracted from the compensation reserve stored in the compensation reserve storage means 22G, the balance of the compensation reserve becomes 200 yen. Here, assuming a provisional transaction, a priority value score (for example, a priority value score of 0.6) that uses up the balance is calculated, and a threshold value is determined.
[0063]
Here, when determining the limit, the limit is fluctuated and managed according to the balance of the reserve fund stored in the reserve fund storage means 22G stored in the reserve fund storage means 22G. Is also good. Specifically, the management may be performed in accordance with the balance of the supplementary reserve or the rate of change of the balance of the reserve.
[0064]
In addition, marketing data, past bidding data, and the like may be statistically processed, and the limit may be changed according to the activity.
[0065]
Further, depending on the past transaction status of the customer and the activity of the market, for example, it is conceivable to compensate preferentially for a good customer or a customer who is likely to be improved based on marketing data.
[0066]
In addition, a priority value score serving as a threshold may be determined in advance, and the necessary supplemental amount having a priority score lower than the threshold may be set as the limit. It is also conceivable to set a predetermined amount as the limit.
[0067]
When the difference indicates a negative value, the compensation determining means 22I determines whether or not the amount corresponding to the difference can be compensated within the limit. Specifically, it is determined whether or not the replenishment reserve stored in the replenishment reserve storage unit 22G exceeds a negative difference that requires replenishment.
[0068]
The second output means 22J outputs a contractable signal indicating that a trade can be established when the compensation determining means 22I determines that compensation is possible.
[0069]
The compensation data processing means 22K, when the contract is established due to the contractable signal output from the first output means 22E, replaces the compensation reserve recognized by the compensation reserve recognition means 22F with the compensation reserve. In addition to performing data processing for accumulating in the storage means 22G, when the contract is established due to the contractable signal output from the second output means 22J, the compensation is performed to compensate for the difference indicating a negative value. It has a function of performing data processing for withdrawing a supplementary reserve from the reserve storage unit 22G.
[0070]
The timing at which this supplementary data processing is performed can be determined according to the characteristics of the product or the administrator's needs, such as at the time of matching, at the time of execution, at the time of product consumption, or at the time of cancellation. In the present embodiment, the processing is performed when the product is consumed, that is, when a signal indicating that the travel ticket or the like has been used and the product has been consumed is transmitted from the contract control unit 22L described later to the compensation data processing unit 22K. In addition, when this positive difference is accumulated, it may be possible to accumulate it separately from the replenishment reserve, for example, for guaranteeing cancellation damage.
[0071]
The contract control means 22L controls confirmation and cancellation of the contract, provisional holding of the product, cancellation of the provisional holding, consumption of the product, and the like, and the status of the transaction (the contract confirmation state Or temporary holding state). Further, it instructs the supplementary data processing means 22K to perform supplementary data processing based on the contract data and the like. Specifically, the control is performed based on the contractable signal from the first output means 22E and the second output means 22J and various data transmitted from the buyer terminal device P1 or the seller terminal device P2. Do.
[0072]
The commodity retrieval device SRV3 is for retrieving a commodity desired by the purchaser, and upon receiving a retrieval command signal from the retrieval command means 22B, a function of retrieving desired sales data relating to the provided commodity according to the desired purchasing data. And has a function of exchanging data with the seller terminal device P2 such as confirmation and cancellation of a contract, provisional holding of a product, and cancellation of provisional holding.
[0073]
More specifically, the product search device SRV3 searches for a purchase desired product of a purchaser by using search condition data receiving means 23A, purchase intention data receiving means 23B, product search means 23C, and search result output means 23D. At least.
[0074]
The search condition data receiving means 23A receives search condition data including data on search conditions for a product desired by the buyer. In the present embodiment, the search condition data receiving means 23A receives purchase desired data as a search condition. Specifically, the product shown in FIG. 11 is received as a search condition.
[0075]
The purchase intention data receiving means 23B relates to the purchase decision of the buyer such as the finalized decision data indicating the final purchase decision transmitted from the purchaser side terminal device P1 and the temporary hold data for provisional reservation. It accepts data. The present embodiment also has a function of receiving data such as confirmation and cancellation of a contract, provisional holding of a product, and cancellation of provisional holding, and exchange of such data with the seller-side terminal device P2. I have.
[0076]
The product search means 23C searches for a product matching the search condition of the search condition data from a product DB 3B provided in a plurality of seller-side terminal devices P2 communicably connected to the product search device SRV3. It is. Then, it is set that the search is repeatedly performed at predetermined intervals until the purchase intention data, in this embodiment, the temporary hold data is received. It should be noted that a search target includes a search for a product group including a single product and a plurality of products.
[0077]
The search result output unit 23D functions to output the search result searched by using the product search unit 23C to the sales request data receiving unit 22C of the sales support device SRV2 as provided product data.
[0078]
The seller-side terminal device P2 functions as a transmission / reception unit 3A, a product DB 3B, and an input unit 3C.
[0079]
The transmitting / receiving means 3A is for transmitting / receiving various data to / from the server SRV, and is mainly constituted by a communication interface or the like.

[0081]
The input means 3C is for the seller to input the data of the desired purchase price and the desired goods stored in the commodity DB 3B, and receives the data mainly by the input means 106 such as a keyboard.
[0082]
3. Operation example
Next, an operation example of the system of the present embodiment will be described with reference to FIGS.
[0083]
For example, when a schedule for a meeting or the like is entered, the purchaser Y starts application software for schedule management as shown in FIG. 11, and inputs schedule data on the date when the schedule is entered. In the present embodiment, a case where 13:00, conference, and Fukuoka are entered in the column on July 2 will be described.
[0084]
On the other hand, the purchase desire condition extraction device SRV1 automatically starts a schedule data automatic detection program when a predetermined time is counted by a timer (not shown) using the automatic detection means 21A. Then, a step of connecting to the buyer-side terminal device P1 in a communicable state and circulating through a plurality of predetermined buyer-side terminal devices P1 to automatically detect schedule data including at least data relating to a date. Repeat.
[0085]
Then, as shown in FIG. 12, when new schedule data is detected (Step S1: Yes), the schedule data received by the schedule data receiving means 21B using the automatic detection means 21A is received (Step S2). Specifically, it receives data relating to the date of July 2 and data indicating a schedule such as “meeting” or “Fukuoka” described in the date column.
[0086]
Receiving such schedule data, purchase desire condition extraction apparatus SRV1 determines whether or not a product required for execution of the schedule has already been arranged (step S3), and confirms that it is in an unarranged state. Then, planning is started (step S4).
[0087]
Here, the planning step will be described in detail with reference to FIG.
[0088]
First, the purchase desired condition extraction device SRV1 reads out plan data and the like stored in the data storage unit 21G to create a plan required to execute the schedule received by the schedule reception unit 21B (step S1). S101), a plan is created based on the contents included in the schedule data and the purchaser data stored in the data storage unit 21G.
[0089]
Specifically, it is assumed that the purpose is a meeting, the start time of the meeting is 13:00, and the venue is Fukuoka. Then, first, plan data relating to the movement is read. At this time, it is defined that the travel plan, the departure place, the departure time, the arrival place, and the arrival time must be defined as the travel plan data. Further, when the purpose is a meeting, various conditions such as arriving 20 minutes before the start and setting the departure place to a company are predetermined as plan data. Therefore, when the meeting start time is received as 13:00, the arrival time is automatically converted from the start time, and a plan to arrive at the venue at 12:40 is created. Further, since a company address or the like is stored in advance as purchaser data, a plan is created by automatically applying the purchaser's company address to the place of departure. In addition, the route search means 21E is used to create a plurality of patterns of routes to reach the destination, create a plurality of plans based on a plurality of route patterns, and execute schedules such as day plans and lodging plans. Create multiple plans. Note that a plan may be created with a single product, or a plan may be created with a product group composed of a plurality of products.
[0090]
Then, items that are not automatically determined in the above steps, for example, conditions desired by the purchaser, such as transportation means and departure time, are filled by using the question data creation means 21F and the like.
[0091]
Specifically, based on the conditions derived from the schedule data, question data for deriving desired purchase conditions of the product required for the schedule is created (step S102). In other words, in order to derive the necessary conditions for arranging transportation and accommodation facilities, "Where is the destination?""What is the desired arrival time?""What is the desired departure time?" Create question data that asks "Where is the place?", "What is your desired transportation mode?", "What is your desired purchase price?" Further, when creating question data, question data is created by predicting required products based on various types of purchaser data stored in the data storage unit 21G. Specifically, for example, when the purpose is a meeting and the destination is Fukuoka, the distance to the destination is determined based on the purchaser's position data stored as the company address, and the distance between the two is determined. If it is far away, and there is a need for transportation such as an airplane or a bullet train, question data for arranging such transportation is created. In addition, if the schedule data contains a character string that seems to be a destination such as “Fukuoka”, create question data that prompts confirmation such as “Is the destination in Fukuoka?” Is also conceivable. Furthermore, it is conceivable to create question data for presenting a product predicted based on a past purchase history. Although the present embodiment is configured so that it can be selected from predetermined question data stored in the data storage means, it may be created sequentially. When the question data is created in the above step, the question data is transmitted to the buyer terminal device P1 in a displayable state as shown in FIG. 14 (step S103).
[0092]
Next, when the answer data for the question data is received (step S104), the purchase request conditions extracted from the schedule data and the answer data are stored, and the purchase request conditions required for creating the purchase request data are stored. It is determined whether the condition is satisfied (step S105).
[0093]
If it is not satisfied (step S105: No), question data is created and transmitted again in order to obtain the missing purchase desired conditions. On the other hand, if the desired purchase conditions required to generate the desired purchase data are satisfied (step S105: Yes), the desired purchase data relating to the product satisfying the desired purchase conditions is generated (step S106). . That is, the purchase desire data creation means 21J creates purchase desire data relating to a product having purchase desire conditions extracted from the answer data. For example, as the purchase desired conditions, “departure place” is accepted as “Tokyo”, “destination” is “Fukuoka”, “desired arrival time” is “12:00”, and “desired purchase price” is received as “40000 yen”. In this case, the purchase request data is created by using the airplane ticket satisfying the purchase request condition as a product. If there is a possibility of accommodation, purchase request data that satisfies an accommodation plan for reserving accommodation facilities is created. As shown in FIG. 15 of the present embodiment, when a plurality of products are required to execute the schedule included in the schedule data, purchase desire data for a series of product groups is created.
[0094]
Then, the purchase request data created in this way is output to the purchase request data receiving means 22A of the sales support device SRV2 (step S107).
[0095]
On the other hand, referring to FIG. 16, the sales support apparatus SRV2 that has received the purchase request data having at least the purchase request amount (step S201) searches for a product combination that matches the purchase request data, and searches the product search apparatus SRV3. Is transmitted (step S202). That is, as shown in FIG. 15, first, a combination such as a basket frame 1 which is a product group composed of a plurality of products such as air tickets and accommodation facilities is provided as an accommodation plan that matches the purchase desire data. A combination such as basket frame 2 is set as a day plan. The search condition of each desired product to be purchased is, for example, an airplane arriving from Fukuoka to Tokyo, with a departure time such as a flight departing from 18:00 on July 1, 2002 and arriving before 20:00. It is also possible to set product conditions having a certain width with respect to the arrival time or airline. Further, it is also possible to set conditions that specify the airline and flight number.
[0096]
Here, the search process for the purchase desired product will be described in detail with reference to FIG.
[0097]
When the search condition data receiving unit 23A receives search condition data from the search instruction unit 22C and search condition data relating to the search condition of the product included in the purchase desire data (step S301), the product search device SRV3 determines that the search condition has been satisfied. A search for a suitable product is started (step S302). That is, a product that matches the search condition data is searched from the product DB 3B provided in the plurality of seller-side terminal devices P2 communicably connected to the product search device SRV3. At this time, if a product group including a plurality of products is to be searched, the search is performed using the total price as a guide. It is also conceivable to create a product group composed of the products included in the plan data in advance so that a product group composed of a plurality of products can be selected from the products possessed by the seller-side terminal device P2. Can be Also, individual products may be searched using the approximate amount of money allocated to each product as a guide.
[0098]
Then, upon receiving the sales request data on the merchandise that matches the search condition from the seller terminal device P2 (step S303), the sales request data is output to the sales request data receiving means 22C of the sales support device SRV2 as a search result. (Step S303).
[0099]
The product search device SRV3 includes a timer (not shown), and repeats the product search at a predetermined timing such as 10 hours or 1 day (step S304: Yes). Then, the search is terminated upon receiving the provisional hold data transmitted from the buyer terminal device P1 (step S305).
[0100]
Then, as shown in FIG. 18, the merchandise search device SRV3 searches the merchandise DB 3B of the seller terminal device P2 for a merchandise item corresponding to the content of the purchase request data, and the sales support device SRV2 determines The data accepting unit 22C accepts sales desire data on the provided product returned in response to the search command signal (step S203). More specifically, for a plurality of products included in the basket frame, provided products that match the sales desire data (for example, in the case of an outbound flight ticket between Tokyo and Fukuoka of the basket frame 1, airline company A, Tokyo July 1) 19:00 departure on the day, 20,000 yen, airline company B, departure at 20:00 on July 1, Tokyo
22,000 yen).
[0101]
Next, a difference is calculated by subtracting a desired selling price from a desired purchasing price of a plurality of products included in each basket frame. Note that the desired purchase price and the desired sale price are the total amount of a plurality of products. If the difference is a positive value (step S204: Yes), no damage is caused, and the contractable signal is output from the first output means 22E (step S207). If the difference calculated by the difference calculation means 22D indicates a positive value, that is, if the desired purchase price is higher than the desired sale price, the difference can be accumulated using the replenishment reserve recognition means 22F. It is recognized as a replenishment reserve.
[0102]
On the other hand, if the difference indicates a negative value (step S204: No), a compensation plan is acquired as to whether the negative value can be compensated (step S205). More specifically, a limit for withdrawing the replenishment reserve from the replenishment reserve storage unit 22G is managed using the replenishment limit management unit 22H, and if the replenishment reserve is not exceeded, it is determined that replenishment is possible.
[0103]
In the present embodiment, the limit is managed based on the compensation priority score calculated according to the compensation formula defined below. Specifically, the compensation priority score is calculated by a necessary compensation amount (a difference indicating a negative value) / (purchase desired price + sale desired price). For example, if the desired purchase price is 100 yen and the desired sale price is 120 yen, the difference (required replacement amount) is minus 20 yen. Therefore, the priority score is 20/220 ≒ 0.09. This priority score is always larger than 0 and equal to or smaller than 1, and is an index by which the smaller this value is, the higher the priority is.
[0104]
Then, a threshold value of the priority score virtually obtained from the past transaction is derived, and the limit amount in the current compensation is managed based on whether the current priority value score exceeds the threshold value of the priority value score. As a method of calculating the threshold value of the priority value score, first, the priority value score is calculated based on a certain number of transaction results in the past, specifically, transaction results selected based on the number of transactions, the transaction period, the total transaction volume, and the like. This transaction result, that is, all pairs of the sell data and the buy data are once matched, and the difference between each pair is calculated. Then, sorting is performed in the descending order of difference (indicating a positive value).
[0105]
On the other hand, the income (total of commissions + total profit) generated in the matching is calculated. At this time, a limit value that can be compensated by the compensation reserve stored in the compensation reserve storage unit 22G is derived. Further, in order to accurately calculate, as a threshold, a priority value score larger than the priority value score which has become the limit value by the above-described calculation method within a range in which compensation is possible, the compensation value is stored in the compensation reserve storage means 22G. The amount of compensation in the priority value score that has become the limit value is subtracted from the compensation reserve that is present, and a priority value score that becomes a limit when the difference is used for compensation is derived. Specifically, it is assumed that the compensation amount at the priority value score 0.5 is 10500 yen. At that time, the replenishment reserve stored in the replenishment reserve storage unit 22G is 10700 yen, and if the next transaction is to be established, the priority score is 0.7 and the replenishment amount is required to be 10750 yen. Then, the priority value score serving as the limit value is 0.5. However, in this case, when the compensation amount in the priority value score which has become the limit value is subtracted from the compensation reserve stored in the compensation reserve storage means 22G, the balance of the compensation reserve becomes 200 yen. Here, assuming a provisional transaction, a priority value score (for example, a priority value score of 0.6) that uses up the balance is calculated, and a threshold value is determined.
[0106]
If the priority value score exceeds the threshold, the compensation determining means 22I is used to determine whether the amount corresponding to the difference can be compensated within the limit.
[0107]
Next, when it is determined that the compensation can be made (step S206: Yes), a contractable signal indicating that the trade can be established is output to the contract control means 22L using the second output means 22J (step S206: Yes). Step S207).
[0108]
As described above, when the contract control unit 22L receives the contractable signal, the server SRV transmits contractable plan information to the buyer-side terminal device P2 as shown in FIG. 12 (step S5). . Further, when it is possible to execute a plurality of products, the plan information is transmitted to the buyer terminal device P2 in a state where the various products can be selected.
[0109]
On the other hand, the purchaser's terminal device P1 that has received the contractable data displays the contractable commodities on the display means 1C in a selectable manner as shown in FIG. Then, when the purchaser selects a desired product from the displayed product data and presses a “temporary holding” button on the screen, the plan selection information is stored in the server SRV. The holding data is transmitted in a state of being associated with the purchaser identifier.
[0110]
The server SRV that has received the plan selection information including the temporary hold data (step S6) arranges for the products included in the selected plan as shown in FIG. 19 (step S7). Specifically, referring to the flowchart shown in FIG. 20, first, purchase condition data necessary for arrangement is obtained (step S401).
[0111]
The purchase condition data 215G includes, for example, conditions required when purchasing an air ticket, specifically, departure time, departure place, name, age, gender, airline, destination, arrival time, flight number, In addition to the general content required for purchase from any seller, such as the desired seat and payment method, the content that differs for each seller (site) is included. This purchase condition data acquisition step is performed using the purchase condition generation means 21L, and reads out purchaser information such as a name from the purchaser data, or uses the question data creation means 21F or the like to obtain necessary information from the purchaser. This is done by collecting different data.
[0112]
When the acquisition of the purchase condition data is completed, the product data and the temporary hold data are transmitted to the seller terminal device P2 together with the purchase condition data in order to temporarily hold the selected product (step S402). If the temporarily held product is judged to be negative by the difference calculating means 22D and needs to be compensated (step S403: Yes), the difference is stored in the compensation reserve storage means 22G. Data processing for securing a lump sum is performed to secure a replenishment reserve (step S404). Then, the status of the transaction is updated to the temporary holding state (step S405). Here, the “status” refers to a state representing a transaction state such as a temporary holding state or a product cancellation state.
[0113]
As described above, when the commodity arrangement is completed, the arrangement state is updated to the arrangement completed state using the arrangement state management means 21C (step S8).
[0114]
Next, the stage at which purchase is determined for a temporarily pressed product will be described with reference to FIGS.
[0115]
When the server device SRV receives the purchase decision data transmitted from the buyer terminal device P2 (step S501), the server device SRV automatically notifies the seller that the temporary hold state has changed to the purchase decision state to the seller. The purchase decision data is transmitted to the terminal device P2 (step S502).
[0116]
Then, for example, when the delivery and the settlement of the ticket are completed, the seller side terminal device P2 notifies the server device SRV to that effect. Then, when the server SRV receives the settlement data of the brokerage commission, which is stored as the compensation reserve, here (step S503), the server SRV stores the commission in the compensation reserve storage unit 22G (step S504), and Is updated to the purchase state (step S505).
[0117]
Next, a case where the temporarily pressed product is temporarily canceled will be described with reference to FIGS.
[0118]
When the server SRV receives the temporary hold cancel data transmitted from the buyer terminal P2 (step S601), the server SRV notifies the seller that the temporary hold has been canceled from the purchaser to the seller terminal P2. The temporary hold cancel data is automatically transmitted to (step S602).
[0119]
Then, the server SRV performs data processing for canceling the reserving of the replenishment reserved as the lump-sum of the replenishing reserve to the replenishment reserve storage means (step S603), and updates the status to the temporary hold cancel state. (Step S604). Note that a setting may be made such that a temporary holding fee is collected depending on the temporary holding cancellation period.
[0120]
Next, a case where the purchased product is consumed (in the present embodiment, a case where an airline ticket is used, for example) will be described with reference to FIG.
[0121]
When the server SRV receives the notification from the buyer terminal device P2 or the digest data notifying that the product has been digested by the pseudo push, the server SRV performs compensation data processing. Specifically, when the contract is established using the compensation data processing means 22K due to the contractable signal output from the first output means 22E, the compensation is made by the compensation reserve certification means 22F. Data processing for accumulating the replenishment reserve in the replenishment reserve storage means 22G, and when a contract is established due to a contractable signal output from the second output means 22J, a negative value is set. In order to compensate for the difference shown, data processing for withdrawing the compensation reserve from the compensation reserve storage means 22G is performed.
[0122]
Next, a case where a product after a product purchase is canceled will be described with reference to FIG.
[0123]
Upon receiving the temporary hold cancel data transmitted from the purchaser's terminal device P2, the server SRV performs a data process for canceling the reserving as a lump sum of the refilling reserve to the refilling reserve storage means. Do it.
[0124]
In the above system, not only when the desired purchase price is higher than the desired sale price, but also when the desired purchase price is lower than the desired sales price and the difference shows a negative value, the transaction can be completed. Further, it is possible to achieve a transaction which cannot be considered in the conventional transaction form, and to dramatically improve the transaction closing rate. Further, it is possible to avoid a risk that has been a drawback in the case of establishing a transaction showing a negative value in the related art, and to surely perform a positive commercial transaction in the total transaction. In other words, while guaranteeing that the total difference will not be negative at all times, it will also be able to close deals that could not normally be traded, break the difficulties and scarcity of deals, and automatically avoid damages As a result, the speed at which a transaction is completed can be secured.
[0125]
Further, when the contract is established by the transaction support device SRV2 based on the contractable signal output from the first output means, the compensation reserve recognized by the compensation reserve recognition means 22F is stored in the compensation reserve money. Means for performing data processing for reserving the means, and storing the compensation reserve to compensate for a negative difference when the contract is established due to the contractable signal output from the second output means. The provision of the compensation data processing means 22K for performing data processing for withdrawing the compensation reserve from the means 22G makes it possible to accurately grasp the compensation reserve and enhance the stability of transactions.
[0126]
Further, a search command means 22B for outputting a search command signal indicating that a search should be performed from a database storing the provided products, and a sales request for receiving sales desired data on the provided products returned in response to the search command signal. The provision of the data receiving means 22C makes it possible to automatically detect a provided product corresponding to the content of the purchase desire data, and to quickly and simply complete the transaction.
[0127]
In addition, the limit for withdrawing the reserve from the reserve reserve storage means is managed based on whether a value determined based on the required replenishment exceeds a threshold calculated from past transaction results, and the replenishment reserve is managed. This avoids the danger that the money will be used up in a short period of time and cannot be compensated for in the next transaction, and it will be possible to determine a reasonable limit for continuing many transactions.
[0128]
In addition, by managing the maximum amount of withdrawal reserves from this replenishment reserve storage means according to the past trading conditions of the customer and the activity of the trading market, it is possible to close transactions in anticipation of future profits It can be.
[0129]
Further, for example, when the balance of the reserve reserve stored in the reserve reserve storage means has decreased below a certain rate or when the balance has shown a rapid decrease rate, the balance of the reserve reserve is determined according to the balance of the reserve reserve. By managing the limit by changing the amount, the continuity of the system can be maintained and stable operation can be realized.
[0130]
In addition, by managing the limit amount in consideration of the reserve for cancellation in order to respond to the case where the execution of the trade is canceled, even if the contract with a positive difference is cancelled, it will be damaged. A supplementary system can be constructed.
[0131]
In addition, as a configuration for calculating a difference between a total desired purchase price for a plurality of products or services and a total desired sell price for a plurality of products or services specified by the sales request data corresponding to the content of the purchase desired data. Because of this, this does not depend on the price of each individual product or service, and the possibility of compensation is considered based on the total price.For example, when calculating the difference between the desired purchase price and the desired sale price of each product or service, Even if it is impossible to make up a contract and a contract cannot be made, the contract can be made by mutually supplementing a plurality of products or services, and the transaction closing rate can be dramatically improved.
[0132]
Note that the present invention is not limited to the above embodiment. For example, a price having a predetermined width may be received as the desired sale price and the desired purchase price. In this case, however, the difference calculation means 22D is used to compare the desired sales data with the desired purchase data and calculate at least the difference between the minimum purchase price and the maximum offer price. It may be determined whether the contract is possible based on the difference.
[0133]
Further, in the present embodiment, the compensation limit is managed between one market, but the compensation limit may be managed across a plurality of markets. Furthermore, application to an auction-type market is also conceivable. Further, in the present embodiment, the management entity of the server SRV and the seller terminal device P2 is configured separately, but a sales support system that manages the stock status of each branch of the company by using both as the same entity. It may be used as a system.
[0134]
In addition, for example, in the present embodiment, the configuration is such that schedule data can be automatically detected. However, for example, when a schedule such as a meeting is entered, the purchaser Y receives a request from his / her own purchaser side terminal device P1. You may be comprised so that it may log in to the server apparatus SRV and transmit schedule data. Further, in the present embodiment, the schedule data can be input by free text, but the schedule data can be input by selecting a destination or a departure place from predetermined options. You may. The functions of the purchase condition extraction device SRV1, the sales support device SRV2, and the product search device SRV3 may be provided in the purchaser terminal device P1 or the seller terminal device P2, or may be provided separately. Of course, it is good.
[0135]
Further, for example, it is also conceivable to provide a cancel data receiving unit so that when a product whose purchase has been previously decided is canceled, the substitute product is searched for and presented to the canceled purchaser. As a result, it is possible not only to obtain an opportunity to sell a substitute product of the canceled product, but also to present a product that is attractive and necessary to the buyer based on the information of the canceled product. For example, when a rental car at a travel destination is canceled, it is conceivable to search for and present an optional tour to be held during that time.
[0136]
Further, in the present embodiment, the search is terminated when the temporary hold data is received. However, the search is terminated when the final purchase decision data is received or when a certain period such as one month has elapsed. May be.
[0137]
【The invention's effect】
As described above, according to the present invention, a transaction is established not only when the desired purchase price is higher than the desired sale price but also when the desired purchase price is lower than the desired sale price and the difference is a negative value. Therefore, it is possible to achieve a transaction that cannot be considered in the conventional transaction form and dramatically improve the transaction closing rate. Further, it is possible to avoid a risk that has been a drawback in the case of establishing a transaction showing a negative value in the related art, and to surely perform a positive commercial transaction in the total transaction. In other words, while guaranteeing that the total difference will not be negative at all times, it will also be able to close deals that could not normally be traded, break the difficulties and scarcity of deals, and automatically avoid damages As a result, the speed at which a transaction is completed can be secured.
[0138]
Further, when the contract is established due to the contractable signal output from the first output means, the transaction support apparatus stores the compensation reserve recognized by the compensation reserve recognition means in the compensation reserve storage means. When the contract is established due to the contractable signal output from the second output means and the data is processed for the accumulation, the compensation reserve money storage means is provided to compensate for the difference indicating a negative value.

Further, the apparatus further includes search command means for outputting a search command signal indicating that a search should be performed from a database storing the provided product, and sales request data for receiving sales request data on the provided product returned in response to the search command signal. The provision of the receiving means makes it possible to automatically detect a provided product corresponding to the content of the purchase desire data, and to quickly and simply complete the transaction.
[0140]
In addition, the limit for withdrawing the reserve from the reserve reserve storage means is managed based on whether a value determined based on the required replenishment exceeds a threshold calculated from past transaction results, and the replenishment reserve is managed. This avoids the danger that the money will be used up in a short period of time and cannot be compensated for in the next transaction, and it will be possible to determine a reasonable limit for continuing many transactions.
[0141]
In addition, by managing the maximum amount of withdrawal reserves from this replenishment reserve storage means according to the past trading conditions of the customer and the activity of the trading market, it is possible to close transactions in anticipation of future profits It can be.
[0142]
Further, for example, when the balance of the reserve reserve stored in the reserve reserve storage means has decreased below a certain rate or when the balance has shown a rapid decrease rate, the balance of the reserve reserve is determined according to the balance of the reserve reserve. By managing the limit by changing the amount, the continuity of the system can be maintained and stable operation can be realized.
In addition, by managing the limit amount in consideration of the reserve for cancellation in order to respond to the case where the execution of the trade is canceled, even if the contract with a positive difference is cancelled, it will be damaged. A supplementary system can be constructed.
[0143]
A configuration for calculating a difference between a total desired purchase price for a plurality of products or services and a total desired sell price for a plurality of products or services specified by the desired sales data corresponding to the content of the desired purchase data; It is also possible to do. As a result, whether or not compensation is possible is considered based on the total price without depending on the price of each product or service. For example, if the difference between the desired purchase price and the desired sale price of each product or service is calculated, compensation is not possible. Even if it is impossible to make a contract, it is possible to make a contract by mutually complementing a plurality of products or services, and it is possible to dramatically improve the transaction closing rate.
