Description

  The present invention relates to a transaction management server for determining the purchase and sale conditions of goods via a network.

  As a technique for evaluating a product or service using an evaluation index and determining whether or not the content of an estimate is appropriate, Patent Document 1 is known. There is also a system for listing products produced by individuals or the like in online shopping malls.

JP 2004-326477 A

  However, in the prior art, the price of the exhibit is determined by the exhibitor. In particular, sellers with relatively low market research capabilities, such as individuals, who handle a small number of products, are difficult to set an appropriate price, and the seller's desired selling price and the price that the buyer can purchase. Deviation tends to occur. As a result, the buyer could not judge the purchase and missed the opportunity to trade.

  In view of such a situation, the present invention aims to provide a technology that enables a buyer to determine a transaction price after acquiring a product when the buyer wishes to determine the transaction price after acquiring the product. .

  The transaction management server of the present invention is connected to an exhibitor computer and a buyer computer via a network. The transaction management server of the present invention includes a product DB, an exhibitor DB, an exhibition information acquisition unit, a selection information acquisition unit, an evaluation information acquisition unit, a price calculation unit, and a price determination unit. The product DB records the identifier of the exhibitor, the desired sales price, the evaluation information, and the price with evaluation conditions for each product. The exhibitor DB records evaluation information for each exhibitor. The exhibition information acquisition unit acquires the identifier of the exhibitor, the desired sales price of the product, and the price with the evaluation condition of the product from the exhibitor computer. The selection information acquisition unit transmits the price desired for sale of the product and the price with evaluation conditions for the product to the buyer computer, and determines the method for determining the transaction price from the buyer computer as the desired price for sale, and the price with evaluation conditions. Is used to obtain information indicating which method to select based on the evaluation is selected. “Select the method to determine the desired sales price” is expressed as “Select the desired sales price method”, and “Select the method to be determined based on the evaluation using the price with evaluation condition” is “Evaluation variable price method” May be expressed as “select”. When the buyer computer selects the evaluation variable price method, the evaluation information acquisition unit requests evaluation from the buyer computer and acquires evaluation information from the buyer computer. The price calculation unit calculates the adjusted purchase price based on the evaluation information when the buyer computer selects the evaluation variable price method. The price determination unit sets the desired sales price as the transaction price when the buyer computer selects the desired sales price method, and sets the adjusted purchase price as the transaction price when the buyer computer selects the evaluation variable price method. However, the desired sales price is higher than the price with an evaluation condition. The adjusted purchase price increases as the evaluation indicated by the evaluation information increases, and decreases as the evaluation indicated by the evaluation information decreases.

  According to the transaction management server of the present invention, since the transaction price can be determined after the product is acquired by evaluating the seller or the product by the buyer, the buyer can purchase the product even from an individual who does not have credit such as an individual. It becomes easy to do. In addition, the exhibitor is less likely to miss the opportunity to trade.

  Hereinafter, embodiments of the present invention will be described in detail. In addition, the same number is attached | subjected to the structure part which has the same function, and duplication description is abbreviate | omitted.

  FIG. 1 is a diagram illustrating a configuration example of a transaction price adjustment system. 2 is a processing flow example of the transaction price adjustment system, FIG. 3 is a detailed processing flow example of the selection information registration step, and FIG. 4 is a detailed processing flow example of the evaluation information registration step. FIG. 5 shows an example of a product DB (product database), and FIG. 6 shows an example of an exhibitor DB (exhibitor database).

  The transaction price adjustment system includes a transaction management server 100, an exhibitor computer 200, and a buyer computer 300 connected via a network 900. The exhibitor computer 200 and the buyer computer 300 may exist for each exhibitor and each buyer. The transaction management server 100 includes at least a product DB 191, an exhibitor DB 192, an exhibition information acquisition unit 110, a selection information acquisition unit 120, an evaluation information acquisition unit 130, a price calculation unit 140, and a price determination unit 150.

  The product DB 191 records, for each product (for each product ID), at least an exhibitor identifier (exhibitor ID), a desired sales price, evaluation information, and a price with an evaluation condition. As shown in FIG. 5, the product DB 191 may also record information such as product type, product name, product description, product image information, delivery method, product time limit, and the like. The exhibitor DB 192 records evaluation information for each exhibitor (for each exhibitor ID).

  The exhibition information acquisition unit 110 acquires at least the identifier of the exhibitor (exhibitor ID), the desired sales price of the product, and the price with the evaluation condition of the product from the exhibitor computer 200, and records them in the product DB 191 (S110). The desired sales price is higher than the price with an evaluation condition. In addition, other information described above may be acquired, and such information may be recorded in the product DB 191. FIG. 7 is an example of a product registration screen on the exhibitor computer, and FIG. 8 is an example of a product registration confirmation screen on the exhibitor computer.

  The selection information acquisition unit 120 transmits a desired sale price of the product and a price with an evaluation condition of the product to the buyer computer 300, and determines a transaction price determination method from the buyer computer 300 to the desired sale price, and an evaluation. Information indicating which method to select based on the evaluation using the conditional price is selected (S120). More specifically, the processing may be performed as shown in FIG. The buyer computer 300 opens a product purchase screen (S121), designates a product desired to be purchased, and sends the information to the transaction management server 100 (S122). The selection information acquisition unit 120 of the transaction management server 100 sends product information (information recorded in the product ID) including the desired sale price of the product and the price with the evaluation condition of the product to the buyer computer 300 (S123). The buyer computer 300 displays the acquired product information on the screen (S124). FIG. 9 is an example of a screen of the buyer computer at the time of purchase displayed in step S124. The buyer computer 300 selects a method for determining the transaction price from a method for determining the desired sales price and a method for determining based on the evaluation using the price with an evaluation condition, and transmits the information to the transaction management server (S125). ). In the following, “Select the method to determine the desired sales price” is expressed as “Select the desired sales price method”, and “Select the method to be determined based on the evaluation using the price with evaluation condition” is set to “Evaluation”. It may be expressed as “select a variable price method”.

  The transaction management server 100 confirms whether the buyer has selected the evaluation variable price method (S105). In the case of No (when the desired sales price method is selected), the price determination unit 150 of the transaction management server 100 determines the transaction price as the desired sales price, and notifies the seller computer 200 of the transaction price and the instruction for shipping the product. To finish the processing for this transaction (S151). In the case of Yes, the price determination unit 150 of the transaction management server 100 sends an instruction to ship goods to the exhibitor computer 200 without determining the transaction price (S152), and proceeds to step S130.

  When the buyer computer 300 selects the evaluation variable price method, the evaluation information acquisition unit 130 requests evaluation from the buyer computer 300 (S131), acquires evaluation information from the buyer computer (S132), and records it in the product DB 191. (S133). Step S130 is composed of steps S131 to S133. FIG. 10 is an example of a request mail sent to the buyer computer in step S131, and FIG. 11 is an example of an evaluation Web screen displayed on the buyer computer in step S132. In the example of FIG. 11, the evaluation is performed in five stages, but it is not necessary to limit to this.

When the buyer computer 300 selects the evaluation variable price method, the price calculation unit 140 calculates the adjusted purchase price based on the evaluation information (S140). However, the adjusted purchase price is calculated to be higher as the evaluation indicated by the evaluation information is higher and lower as the evaluation indicated by the evaluation information is lower. For example, N is a positive integer, the highest evaluation in N-stage evaluation is N, and the lowest evaluation is 1. Then, the adjusted purchase price P3 is obtained by using the desired sales price P1, the price with evaluation condition P2, and the evaluation value RA (RA is an integer of 1 to N) P3 = P2 + (P1-P2) × (RA-1) / (N-1)
Calculate as follows. By calculating in this way, it is possible to adjust the desired selling price to be the adjusted purchase price when the evaluation value RA is the highest N, and to adjust the price with the evaluation condition to the adjusted purchase price when the evaluation value RA is the lowest one. . In the example shown in FIG. 5, P1 = 3000, P2 = 2000, RA = 3, and N = 5, so P3 = 2500. However, the method for determining the adjusted purchase price need not be limited to this formula. If the purchaser determines that the value is more valuable than the desired sales price, the adjusted purchase price can be set higher than the desired sales price. May be.

Further, the evaluation value RA may be determined only by the evaluation value of the product, or may be determined by a combination with the evaluation value of the exhibitor. For example, when the evaluation value of the product is R1, the evaluation value of the seller is R2 (R1 and R2 are both integers of 1 to N), w1 and w2 are coefficients representing weights, and w1 + w2 = 1.
RA = w1 × R1 + w2 × R2
You can ask as follows. For example, if w1 = 1 and w2 = 0, the evaluation value RA is determined only by the evaluation of the product. If w1 = 0.5 and w2 = 0.5, the two evaluations are treated equally.

  When the buyer computer selects the evaluation variable price method, the price determination unit 150 records the adjusted purchase price as a transaction price in the product DB 191, notifies the seller computer 200 and the buyer computer 300 of the transaction price, and ends the processing. (S153). FIG. 12 is an example of the transaction price determination notification email sent to the buyer computer in step S153.

  According to the transaction management server of the first embodiment, the transaction price can be determined after the product is acquired by evaluating the seller or the product by the buyer. Therefore, the buyer can purchase the product even from an individual who has no credit such as an individual. It becomes easy to purchase. In addition, the exhibitor is less likely to miss the opportunity to trade. Furthermore, if the adjusted purchase price is calculated as described above, the exhibitor can secure the minimum value of the transaction price, so that the seller can feel at ease.

[Modification 1]
In Example 1, the buyer was able to select the valuation variable price method every time. In the first modification, the evaluation variable price method can be selected only for the first transaction for each combination of buyer and exhibitor. The figure which shows the structural example of the transaction price adjustment system of the modification 1 is the same as FIG. 1, and the processing flow is the same as FIG. The transaction management server 100 ′ of the first modification is different from the configuration of the transaction management server 100 of the first embodiment in that it includes a buyer DB 194 and a selection information acquisition unit 220. Others are the same as in the first embodiment. FIG. 13 is a diagram illustrating an example of a processing flow in the selection information acquisition unit 220. The buyer DB 194 records the identifier of the seller of the purchased product for each buyer (for each buyer ID). FIG. 14 is a diagram illustrating an example of a buyer DB (buyer database).

  After Steps S121 and S122, the selection information acquisition unit 220 confirms whether or not the buyer DB 194 has a record purchased by the processing target buyer from the processing target seller (S221). That is, it is confirmed whether or not the buyer who is the subject of the transaction purchases from the seller who is the subject of the transaction for the first time. When step S221 is No, the selection information acquisition unit 220 determines that the buyer computer 300 has selected the desired sales price method (S222), and transmits only the desired sales price of the product to the buyer computer 300 (S223). On the buyer computer 300, only the desired sales price is displayed as the price information of the product (S224). Since it is processed in this way, Step S105 is No, and the desired sales price is determined as the transaction price. If step S221 is Yes, the subsequent processing is the same as in the first embodiment.

  According to the transaction management server of the first modification, the seller can have the authority to determine the price in the second and subsequent transactions of the same seller / buyer combination, so that the seller's position can be reflected.

[Modification 2]
In Example 1, the adjusted purchase price was determined by one evaluation. Therefore, buyers with severe evaluations always buy cheaply, and buyers with poor evaluations always buy high. Thus, in the second modification, the adjusted purchase price is determined in consideration of the buyer's evaluation tendency (history).

  The figure which shows the structural example of the transaction price adjustment system of the modification 2 is the same as FIG. 1, and the processing flow is the same as FIG. The transaction management server 100 ″ of the second modification is different from the first embodiment in that it includes an evaluation history DB 193 in addition to the configuration of the transaction management server 100 of the first embodiment and the calculation method of the price calculation unit 140. The rest is the same as the first embodiment. The evaluation history DB 193 records, for each buyer (for each buyer ID), a history of evaluation information for the purchased product and the seller, and is a diagram illustrating an example of the evaluation history DB (evaluation history database). .

  As shown in the first embodiment, the price calculation unit 140 calculates the adjusted purchase price such that the higher the evaluation indicated by the evaluation information about the transaction is, the higher the evaluation is, and the lower the evaluation indicated by the evaluation information is. Then, in addition to the calculation method, the adjusted purchase price becomes higher as the evaluation indicated by the evaluation information of the processing target buyer recorded in the evaluation history DB becomes lower, and the evaluation information of the processing target buyer recorded in the evaluation history DB. It is calculated so that the higher the evaluation is, the lower it is.

  For example, it may be calculated as follows. This example is a calculation method corresponding to a buyer whose evaluation is always strict, and a five-level evaluation (5 is the highest value), the average value is m, and the standard deviation is σ. As a tendency of buyers who are always strict in evaluation, there is a tendency that the average value of evaluation values is low and the standard deviation of evaluation values is small (variation of evaluation is small). Therefore, the correction value S is set to S = (3-m) / 2 when the conditions of m ≦ 2, 2σ ≦ 1.5 are satisfied, and S = 0 when the conditions are not satisfied. Then, the value obtained by adding S to the evaluation value RA in the transaction is used as the corrected evaluation value RA, and the adjusted purchase price shown in the first embodiment is calculated using the corrected evaluation value RA. As a specific example, the past product evaluation of the buyer B1 in FIG. Therefore, the average m = 1.33 and the standard deviation σ = 0.47. FIG. 16 is an example of a distribution that provides such a statistical value. It can be seen that the evaluation is biased. The average value and the standard deviation satisfy the condition of m ≦ 2, 2σ ≦ 1.5. Therefore, when the correction value S is calculated, S = 0.835. Therefore, if the evaluation value in this transaction is RA = 2, the corrected evaluation value is RA = 2.835. By correcting the evaluation value in this way, the adjusted purchase price can be calculated in consideration of the tendency of buyers who always give strict evaluation.

  According to the transaction management server of the modified example 2, since the adjusted purchase price can be determined in consideration of the buyer's evaluation tendency, the evaluation bias by the buyer can be corrected. Note that Modification 2 and Modification 1 may be combined.

[Program, recording medium]
The various processes described above are not only executed in time series according to the description, but may also be executed in parallel or individually as required by the processing capability of the apparatus that executes the processes. Needless to say, other modifications are possible without departing from the spirit of the present invention.

  Further, when the above-described configuration is realized by a computer, processing contents of functions that each device should have are described by a program. The processing functions are realized on the computer by executing the program on the computer.

  The program describing the processing contents can be recorded on a computer-readable recording medium. As the computer-readable recording medium, for example, any recording medium such as a magnetic recording device, an optical disk, a magneto-optical recording medium, and a semiconductor memory may be used.

  The program is distributed by selling, transferring, or lending a portable recording medium such as a DVD or CD-ROM in which the program is recorded. Furthermore, the program may be distributed by storing the program in a storage device of the server computer and transferring the program from the server computer to another computer via a network.

  A computer that executes such a program first stores, for example, a program recorded on a portable recording medium or a program transferred from a server computer in its own storage device. When executing the process, the computer reads a program stored in its own recording medium and executes a process according to the read program. As another execution form of the program, the computer may directly read the program from a portable recording medium and execute processing according to the program, and the program is transferred from the server computer to the computer. Each time, the processing according to the received program may be executed sequentially. Also, the program is not transferred from the server computer to the computer, and the above-described processing is executed by a so-called ASP (Application Service Provider) type service that realizes the processing function only by the execution instruction and result acquisition. It is good. Note that the program in this embodiment includes information that is used for processing by an electronic computer and that conforms to the program (data that is not a direct command to the computer but has a property that defines the processing of the computer).

  In this embodiment, the present apparatus is configured by executing a predetermined program on a computer. However, at least a part of these processing contents may be realized by hardware.
