The purchaser ID in this case may be an ID input by the purchaser when logging in, or may be an ID assigned to each purchaser terminal 10 . As each purchaser inputs purchase conditions, each purchase condition is accumulated in the purchase condition database.

The seller uses the input device 31 of the seller terminal 30 owned by the seller to input desired sales conditions for the product to be sold by the seller. The candidate creation unit 23 receives the sales conditions input by the seller from the seller terminal 30 . The candidate creation unit 23 creates a list of bid candidates from the purchase condition table stored in the purchase condition storage unit 21 according to the received sales conditions. Candidate creation unit 23 transmits the created list to seller terminal 30 . Thereby, the display device 32 displays the list.

FIG. 4 is an example of a seller screen displayed by the display device 32 . As exemplified in FIG. 4, the screen for the seller is set so that (a) item major category, (b) item minor category, (c) place of origin, and (d) delivery date can be selected. Alternatively, on the screen for sellers, (a) large item classification, (b) small item classification, (c) place of origin, and (d) delivery date are set so that numerical values and characters can be entered.

The candidate creation unit 23 refers to the purchase condition database stored in the purchase condition storage unit 21, extracts purchase conditions that match or are similar to the sales conditions input by the seller as bid candidates, and prioritizes them. Create a list with The candidate creation unit 23 may extract all purchase conditions stored in the purchase condition database and give priority to them. The steps 1 to 3 of creating a list of bid candidates will be described in detail below.

Define the terms of sale x(i) as (a(i), b(i), c(i), d(i)) or part thereof. a(i) is a major item category with sales condition ID=i, such as strawberries (for raw consumption). b(i) is an item small classification b(i) with sales condition ID=i, such as Amaou (registered trademark). c(i) is the production area of sales condition ID=i, such as Fukuoka prefecture, for example. d(i) is the delivery date of sales condition ID=i, which is August 3, 2021 as an example.

When the sales conditions x(i) are input, each purchase condition p(j) in the purchase condition database stored in the purchase condition storage unit 21 = (a(j), b(j), c(j) , d(j), e(j), f(j), g(j)) are ranked. "j" corresponds to the purchase condition ID.

(Creation process 1)
First, the candidate creation unit 23 identifies a set of p(j) where a(i)=a(j). That is, the group G whose item major classification is "strawberries (for eating raw)" is specified.

(Creation process 2)
The candidate creation unit 23 defines one week as "seven days from Monday to Sunday". Note that the delivery time d(i) can be a section such as August 3rd to August 5th, but does not span different weeks. That is, the candidate creation unit 23 determines only one week to which any delivery time d(i) belongs. The candidate creating unit 23 represents the week to which d(i) belongs as w(d(i)). This w(d(i)) means that the d(i)-th day counted from the service start date belongs to the w(d(i))-th week.

The candidate creation unit 23 determines the distance between the two delivery times d(i) and d(j) according to the "difference between weeks to which they belong". Specifically, the candidate creation unit 23 calculates the distance dist(d(i), d(j)) as |w(d(i))-w(d(j))|. For example, d(i) = August 3 belongs to w(d(i)) = 10th week of service start, and d(j) = August 17 belongs to w(d(j)) of service start. = belonging to the 12th week, the distance dist(d(i), d(j))=|10−12|=2.

(Creation step 3)
The candidate creation unit 23 divides the group G into a plurality of groups (17 groups, for example), and ranks the prices and transportation costs within each group in order of advantage to the sellers who input the sales conditions x(i). . For example, the candidate creation unit 23 sets x(i)=(a(i), b(i), c(i), d(i))=(Strawberry (for raw consumption), Amaou (registered trademark), Fukuoka Prefecture , August 3, 2021) are grouped as follows.
_1st group G1: Amaou (registered trademark), same week, Fukuoka prefecture _2nd group G2: Amaou (registered trademark), same week, non-Fukuoka prefecture _3rd group G3: Amaou (registered trademark), 1 week different , Fukuoka Prefecture 4th Group G ₄ : Amaou (registered trademark), 1 week different, non-Fukuoka Prefecture 5th Group G ₅ : Amaou (registered trademark), 2 weeks different, Fukuoka Prefecture 6th Group G ₆ : Amaou (registered trademark) ), 2 weeks different, non-Fukuoka prefecture 7th group G ₇ : Amaou (registered trademark), 3 weeks different, Fukuoka prefecture 8th group G ₈ : Amaou (registered trademark), 3 weeks different, non-Fukuoka prefecture 9th group G ₉ : Strawberry (for raw consumption), same week, Fukuoka prefecture 10th group G ₁₀ : Strawberry (for raw consumption), same week, non-Fukuoka prefecture 11th group G ₁₁ : Strawberry (for raw consumption), 1 week different, Fukuoka prefecture No. 12 Group G ₁₂ : Strawberry (for raw eating), 1 week difference, non-Fukuoka Prefecture 13th Group G ₁₃ : Strawberry (for raw eating), 2 weeks difference, Fukuoka Prefecture 14th Group G ₁₄ : Strawberry (for raw eating), 2 weeks No, non-Fukuoka Prefecture 15th Group G ₁₅ : Strawberry (for raw consumption), 3 weeks difference, Fukuoka Prefecture 16th Group G ₁₆ : Strawberry (for raw consumption), 3 weeks difference, Fukuoka Prefecture 17th Group G ₁₇ : 4 weeks or more Wrong

A higher group with a smaller group number has a higher rank of p(j). Also, within each group Gm, _p (j) are ranked in order of price and shipping costs that are advantageous to the seller who entered this sales term x(i).

The process of creating a list of bid candidates is not limited to the above. For example, a(i), b(i), c(i), and d(i) in terms of sale x(i) = (a(i), b(i), c(i), d(i)) ) are quantified, and each purchase condition p(j) = (a(j), b(j), c(j), d(j), e(j), f(j), g(j)) Numericalize a(j), b(j), c(j), and d(j), calculate the distance between the sales condition x(i) and each purchase condition p(j), and calculate the distance Each purchase condition may be rearranged in ascending order.

Items used in ranking in order of advantage to sellers in each group of the candidate creation unit 23 are not limited to the unit price per unit weight registered in the purchase condition database. Amount obtained by referring to the purchase condition database and adding costs not included in the unit price entered by the purchaser, such as the burden of transportation expenses in the purchase conditions, transportation expenses and taxes estimated from the delivery destination and the seller's address. may be the unit price obtained by dividing by the delivery quantity. In addition, by referring to the purchase condition database, there are costs other than the product price included in the unit price entered by the purchaser, such as the burden of transportation expenses in the purchase conditions, estimated transportation estimated from the delivery destination and the address of the seller It may be a unit price obtained by dividing the amount after subtracting the cost by the delivery amount.

The display device 32 displays the list created by the candidate creation unit 23 in the bid candidate list area of the screen for the seller in FIG. In the example of FIG. 4, purchase conditions A to G are displayed in descending order of priority. In addition, in the example of FIG. 4, (d) delivery date, (g) delivery quantity, and (f) unit price per unit weight are displayed. The displayed unit price may be the unit price of the purchase condition database plus the transportation cost and the tax, or may be the one from which the transportation cost and the tax are subtracted. Also, a plurality of unit prices may be displayed. This allows the seller to easily make a decision based on the selling price and the take-home price. In the example of the screen for the seller in FIG. 4, it is set so that any one of the purchase conditions can be selected. It means that the bid is determined for the terms of purchase selected by the seller. As in the example of FIG. 4, the candidate creation unit 23 preferably anonymizes each purchase condition. By anonymizing each purchase term, fair competition can be achieved.

If the purchase conditions that satisfy the sales conditions desired by the seller are not displayed on the screen for the seller, the seller can notify each purchaser of its own sales conditions. Specifically, when the seller presses the "notify" button on the seller screen, the notification unit 24 notifies each purchaser terminal 10 of the sales conditions. At the time of notification, some sales conditions may be entered in numerical values or characters. Also, a character message may be input at the time of notification. According to this configuration, each purchaser can present purchase conditions that match or are close to the sales conditions desired by the seller.

Alternatively, the sales conditions may be individually notified to any purchaser of the purchase conditions displayed in the bid candidate list area displayed on the screen for the seller. For example, when the seller selects a purchase condition displayed in the bid candidate list area and presses the "notify" button, the notification unit 24 notifies the purchaser of the selected purchase condition of the sales condition individually. do. According to this configuration, it is possible to request the purchaser whose purchase conditions are close to the sales conditions to reconsider the purchase conditions.

The purchase conditions selected by the seller after bidding are passed to the contract processing unit 25 of the matching device 20 . For example, the purchase conditions for which the "Bid" button is pressed on the screen for the seller are passed to the contract processing unit 25 . The bid quantity may be all or part of the selected purchase terms. The contract processing unit 25 performs processing related to the contract between the seller and the purchaser of the purchase conditions determined by the bid. For example, the contract processing unit 25 notifies the seller terminal 30 of the contracted seller and the purchaser terminal 10 of the contracted purchaser that the contract has been completed. If the notice includes the terms and conditions of sale that have been bid on, it may include a link to a web page containing the terms and conditions of sale that have been bid on. Alternatively, the contract processing unit 25 transmits the contract document related to the contract to the seller terminal 30 of the contracted seller and the purchaser terminal 10 of the contracted purchaser.

Also, the contract information storage unit 22 associates the contract information processed by the contract processing unit 25 with the contract ID and stores the contract information in the contract information database. FIG. 5 is a diagram illustrating a contract information database. As exemplified in FIG. 5, the contract information database stores, in association with the contract ID, a purchase condition ID, a purchaser ID, (a) item major classification, (b) item minor classification, (c) production area, and (d) Delivery date, (e) shipping destination, (f) unit price per unit weight, (g) transportation cost burden, (h) delivery amount, and the like are associated with each other. Each time the contract processing unit 25 performs contract processing, the contract information is accumulated in the contract information database.

Next, exchange of information between the units will be described. FIG. 6 is a sequence diagram showing an example of the operation of matching system 100. As shown in FIG. As illustrated in FIG. 6, purchase conditions are transmitted from the purchaser terminal 10 to the purchase condition storage unit 21 . The purchase condition storage unit 21 stores the received purchase conditions in the purchase condition database. When the sales conditions are transmitted from the seller terminal 30 to the candidate preparation unit 23, the candidate preparation unit 23 refers to the purchase condition database stored in the purchase condition storage unit 21, and selects bid candidates according to the received sales conditions. create a list of Candidate creation unit 23 transmits the created list to seller terminal 30 . When the purchase conditions selected by the seller are transmitted from the seller terminal 30 to the contract processing section 25, the contract processing section 25 performs contract processing. For example, the contract processing unit 25 notifies the seller terminal 30 and the purchaser terminal 10 that the contract has been completed. The contract information storage unit 22 stores contract information in a contract information table.

FIG. 7 is a flow chart of processing performed between the matching device 20 and the purchaser terminal 10 . FIG. 8 is a flow chart of processing performed between the matching device 20 and the seller terminal 30 .

As illustrated in FIG. 7, the purchase condition storage unit 21 determines whether purchase conditions have been received from any purchaser terminal 10 (step S1). If the determination in step S1 is "No", step S1 is executed again after a predetermined period of time. If it is determined as "Yes" in step S1, the purchase condition storage unit 21 associates the purchase conditions received in step S1 with the purchase condition ID and stores them in the purchase condition database (step S2). After that, the process is executed again from step S1 after a predetermined period of time.

As illustrated in FIG. 8, the candidate creation unit 23 determines whether or not sales conditions have been received from any of the seller terminals 30 (step S11). If the determination in step S11 is "No", step S11 is executed again after a predetermined period of time.

If it is determined as "Yes" in step S11, the candidate creation unit 23 refers to the purchase condition database stored in the purchase condition storage unit 21, and lists bid candidates according to the sales conditions received in step S11. (step S12). Next, the candidate creating unit 23 transmits the list created in step S12 to the seller terminal 30 (step S13). As a result, a list of bid candidates is displayed on the display device 32 of the seller terminal 30 .

Next, the contract processing unit 25 determines whether or not the selected purchase conditions have been received from the seller terminal 30 (step S14). If the determination in step S14 is "No", step S14 is executed again after a predetermined period of time. If the determination in step S14 is "Yes", the contract processing unit 25 performs contract processing (step S15). The contract information storage unit 22 stores the contract information processed in step S15 in the contract information table. Then, after a predetermined period of time, the process is executed again from step S11.

According to this embodiment, purchase conditions for each purchaser can be stored in the purchase condition database in advance. When the seller inputs his or her desired sales terms, candidates corresponding to the sales terms are created and displayed on the display device 32 of the seller terminal 30 . As a result, the seller can easily search for purchase conditions that satisfy his/her desired sales conditions. A contract is processed simply by selecting the purchase conditions for which the seller has decided to bid. As described above, efficient matching can be realized in a short time.

In the above-described embodiment, agricultural products have been described as an example of products, but the present invention is not limited thereto. For example, industrial products and the like may be used as commodities. However, the above embodiment exhibits a particularly remarkable effect when agricultural products are used as products. Details will be described below.

When agricultural products are used as commodities, due to the nature of the commodities, the seller (producer) cannot decide the transaction based only on the price proposed by the purchaser. This is because the seller decides the transaction by taking into account various factors other than the price, such as his/her productivity and delivery date. These merchant-side "factors" are too complex to be entered into the system. For example, the seller has information that "I can ship 100 kg from August 1st to August 5th, but the upper limit for each day is 50 kg, and I would like to take one day off during these five days." is cumbersome to type. Furthermore, in reality, it is considered that the seller does not clearly recognize such information in his or her brain. Therefore, both cognitive cost and input cost become high.

In each of the above-described embodiments, the seller looks at candidates for purchase conditions and selects one of them, which is determined by the seller. A seller's brain can be viewed as a very smart component. This is because among sellers, information on production and delivery is ambiguously pooled without necessarily taking the form of clear language, and based on this information, sellers decide whether or not to comply with the purchase conditions of each purchaser. This is because it is possible to determine whether In order to accurately guide the decision of the brain of the seller, as in each of the above embodiments, the burden on the seller is reduced by giving each purchaser two choices of "comply" or "not comply" with the purchase conditions. It is possible to encourage the seller to make an accurate judgment while reducing the risk. From the above, each of the above-described embodiments exhibits remarkable effects with respect to agricultural products.

In a so-called auction, purchasers submit bids, and the purchaser who submits the highest bid is automatically bid. Since this auction method does not use the judgment of factors other than the price by the seller, it can be said that it is unsuitable for the case where the producer of agricultural products is the seller.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to such specific embodiments, and various modifications and variations can be made within the scope of the gist of the present invention described in the claims. Change is possible.
