Description

  The present invention relates to a bidding data processing system for merchandise, etc. via a network such as the Internet, and more particularly to a bidding data processing method and a bidding data processing system capable of assigning merchandise shares to a plurality of suppliers.

  Conventionally, in commercial transactions such as auctions, the conditions and desired prices of products that buyers want are presented, and multiple suppliers compete for bid prices over the Internet within a set time (this transaction). Hereinafter referred to as “reverse auction”). In this reverse auction, it is not disclosed where other suppliers are participating in the auction during the auction, and on the computer of each supplier, the company's bid ranking and other companies' lowest bid price are in real time. By being performed in a public situation, it is possible to work the principle of competition among suppliers and reduce the winning bid price.

Instead of purchasing procedures where the optimal price could not be found depending on the balance between people and companies, the reverse auction is an effective means of reducing the purchasing price by making the optimal price more likely to occur without any personal feelings.
However, in reverse auctions, only the transaction method based on price input for a single item product is used, and it is realized at a competitive price between suppliers, so the marginal cost is much lower than that of other suppliers. If there is one supplier that can provide the product at the same time, the buyer cannot purchase the product at the marginal cost of that supplier, and can only purchase the product at a competitive price with other suppliers. There was an inconvenience that a large effect could not be obtained.

Further, in commercial transactions, it is often performed to achieve a volume merit in which the winning bid price is reduced by increasing the quantity of commodities to be traded.
However, in the transaction based on the successful bid price input for a single item by the ASP service as described above, if the buyer's order quantity exceeds the quantity that can be provided by the supplier who can provide the goods at an inherently low price, the supplier can deal with the transaction. The inconvenience that the successful bid price could not be reduced due to the failure to participate in the event.
In addition, depending on the quantity and features of the product, in the case of placing an order with one supplier who bids at the lowest price, there is an inconvenience in process management that the delivery date cannot be kept.

  Furthermore, in the reverse auction, price competition of the winning bid price by multiple suppliers is performed, but even though there is a supplier that can sell below the winning bid price, other suppliers cannot compete with the supplier for the winning bid price. There was also the inconvenience that the decline in winning bids stopped falling.

  Therefore, the present invention has a predetermined fluctuation range by dividing the order quantity of the product in order to reduce the winning bid price in the total number of the order quantity of the product and / or to order the product in a distributed manner to a plurality of suppliers.

  Hereinafter, the flow of bid data processing in the share discount auction will be described with reference to FIG. Note that the share discount auction is an auction that is performed to distribute orders for products to suppliers. The procedure of bid data processing is mainly executed by the processing unit according to a predetermined program stored in the storage unit in the server 20.

First, a buyer user inputs auction definition information using an auction registration screen (step 201).
Here, the auction definition information refers to definition information such as the auction date and time, the auction type, the target product information, and the selected supplier.

  An example of the auction registration screen is shown at 310 in FIG. In 310 of FIG. 3, the input auction definition information includes an auction subject 311 (“copy paper set”), an auction opening date 312 (“2006/10/11 22:00”), and an end date 313 (“2006/10”). / 11 23:00 "), end interval 314 (" 5 minutes "), planned order date 315 (" 2006/10/11 to 2007/11/1 ") and the like.

  In addition, a “share percent type” is input to the above-described auction type in order to perform bid data processing for assigning a share of a product to a plurality of suppliers.

  An example of a share discount type auction registration screen is shown at 410 in FIG. In 410 of FIG. 4, the input auction definition information includes auction type 411 (“share percent type”), share percent 412 (three companies share percent, share 1 is 50 to 75%, share 2 is 40 to 20%. , Share 3 is 10-5%), Share Fluctuation Range 413 (Fluctuation Range Allowed for Each Share in Fixed Share Value Calculation. That is, if Share 1 Fluctuation Range is 10%, Fixed Share Value <50% (Acquired) Lowest possible share value) + 10% (share fluctuation range) = 60%)).

  As mentioned above, share split type auctions allow suppliers to present prices that take volume merits into account and place distributed orders at the lowest price in the total number of products (considering costs), or subject items to risk This auction is useful when you want to place orders with multiple suppliers (considering risk) depending on the level of the product and the production capacity of the supplier.

  Here, since the acquirable share has a fluctuation range, it must be changed to an acquisition share value which is a fixed share value within the fluctuation range of the share when actually placing an order. Therefore, it is necessary to calculate a fixed share value according to the bid price from the fluctuation range of the share. In this calculation, it is necessary to use a fixed share value in consideration of an inexpensive price in the total number of products.

However, when calculating the fixed share value, the fixed share desired by the buyer depends on the risk factors such as the product to be bid and the business condition providing the product. By setting a risk rate or the like other than the share fluctuation range as a variable, it is possible to reflect a risk suitable for the target product.
As an example of calculating the fixed share value, the winning bid price for the obtainable share 1 (50 to 75%) is 1000 yen, the winning bid price for the obtainable share 2 (40 to 20%) is 1050 yen, and the obtainable share. An example of calculation when the successful bid price of 3 (10 to 5%) is 1100 yen is shown.

For example, the acquired share value can be calculated by the following formula using the risk rate (r).
Acquireable share (1) Minimum value = 50%
Acquireable share (2) Minimum value = 20%
Acquired share (3) Minimum value = 5%
Acquireable share (1) Fluctuation range = 25%
Acquireable share (2) Fluctuation range = 20%
Acquireable share (3) Fluctuation range = 5%
Acquired share 21 bid price difference = Acquireable share 2 bid price-Acquireable share 1 bid price = 50 yen Acquireable share 32 bid price difference = Acquireable share 3 bid price-Acquireable share 2 bid price = 50 yen Share 31 bid price difference = Acquirable share 3 bid price-Acquirable share 1 bid price = 100 yen Acquired share value (n) = Acquirable share (n) Minimum value + Acquirable share (n) Fluctuation range x Acquired share (N + 1) (n) Bid price difference / (Share (n + 2) (n) Bid price difference) × 1 / (1-r) (Equation 1)
When calculated in this way, when the risk rate (r) = 0,
Acquired share value 1: Acquired share value 2: Acquired share value 3 = 62.5: 30: 7.5 (the average order amount in this case is 1022.5 yen).
If the risk rate (r) = 0.5 and the share is apportioned so that the total share is 100%, the acquired share value 1: acquired share value 2: acquired share value 3 = 60: 32: 8 (average in this case) The order amount is 1024 yen).
When the risk rate (r) is 0.9 and the share is apportioned so that the total share is 100%, the acquired share value 1: the acquired share value 2: the acquired share value 3 = 54: 37: 9 (average in this case) The order amount is 1027.5 yen).

  In the above description, the acquired share value is calculated using the risk rate (r). However, by setting the risk rate (r) and the share fluctuation range 413 to have the same numerical value or relationship, the setting value of the share fluctuation range 413 is obtained. It is also possible to calculate the risk rate (r). For example, when the share fluctuation range 413 is “10%”, the risk rate is set to 0.5, and when the share fluctuation range 413 is “20%”, the risk rate is set to 0.9, etc. It is also possible to calculate the risk rate based on the input of the share fluctuation range 413 without requiring the input of.

As can be seen from Equation 1, the acquired share value (n) and the acquirable share (n) bid price are in a linear equation relationship, so if one of the variables is determined, the other variable is It is possible to calculate.
In other words, if the desired share value (n) is determined, the necessary obtainable share (n) bid price can be calculated, and conversely, the obtainable share (n) bid price necessary for making a successful bid is determined. For example, the acquired share value (n) can be calculated.
Therefore, in the case of share discount auctions, by using these formulas and algorithms, by displaying the available share and the bid price, the incentive of increasing the acquired share value works for the supplier, and a cheaper successful bid price can be obtained. It is possible to obtain.

  In addition, in the share percent 412, a three-company share percent is selected, but in this case, the share that can be acquired is always assigned to three companies and orders are placed. In that case, it is possible to place an order only with the largest share (share 1), with share 2 being the second cheapest bid price and share 3 being the second or third cheapest bid price. .

Therefore, if you do not place an order with 3 companies and the bid price difference in each share that can be acquired widens widely, priority is given to the cost of the total number of products. In some cases.
Therefore, in order to reduce the number of distributed ordering companies in consideration of cost, it is possible to use the set value of the share fluctuation range 413.
For example, as described above, when the risk rate (r) = 0, the acquired share value 1: the acquired share value 2: the acquired share value 3 = 62.5: 30: 7.5 (in this case, the average order amount is However, in this case, the fluctuation range of the acquired share 1 exceeds 10% set in the share fluctuation range 413 (62.5% -50% (the lowest shareable value)) )> 10% (share fluctuation range)) Therefore, it may be calculated that the distributed order is changed from 3 companies to the top 2 companies and the acquisition share value of the obtainable share 1 is set to the maximum (75%).
In this case, by setting the acquisition share value of the acquireable share 1 to 75% and the acquisition share value of the acquireable share 2 to 25%, the average order amount per product in the total number of products is 1000 × 0.75 + 1050. × 0.25 = 1012.5 yen, which is cheaper than the above 1022.5 yen.
As described above, in the share discount auction according to the present invention, a plurality of prices considering volume merits are bid for each of a plurality of acquirable shares decided in advance, and a target item is shared with a plurality of suppliers according to risks. It is possible to place an order in consideration of costs.

Product information is also defined as auction definition information.
An example of a product information registration screen in the share discount auction is shown at 510 in FIG. In 510 of FIG. 5, the input product information includes product name 511 (“copy paper A4”), quantity 512 (“100”), unit 513 (“case”), start price 514 (supplier is “500000” yen). Bid below), target price 515 (“400,000” yen that can only be displayed on the buyer screen), minimum reduction unit 516 (previous bid price-can only be bid below “10,000” yen), bid possible unit 517 (can be bid at an integer multiple of “5000” yen), specifications 518 (“vertical”), delivery address 519 (“2-5-5 Hitotsubashi, Chiyoda-ku, Tokyo”), delivery date specification 520 (blank ), Lead time 521 of delivery date (“within 3 days after ordering”).
When the product addition button 522 is pressed, an input similar to that described above is made for the second product, and an auction for a plurality of items is possible.

  Next, the auction definition information input by the buyer is transmitted from the buyer-side computer 30 to the server 20 (step 202). The definition information (step 203) received by the server 20 is stored in the storage unit, and the supplier user accesses the auction screen generated by the bid data processing system on the supplier computer 40, thereby providing the supplier computer. 40 (step 204). On the screen displayed on the display of the supplier-side computer 40, other supplier information and the target price cannot be seen.

  Next, the supplier receives the auction definition information (step 205), and confirms the auction definition information using the auction screen (step 206).

  Next, it is determined whether or not the auction opening date entered in the auction definition information is reached. When the auction opening date is reached, a holding mail is transmitted from the server 20 (step 207), and the holding mail is received by the supplier computer 40. (Step 208). In step 207, the hosting mail may be transmitted at an arbitrary timing by the buyer operating the hosting mail.

Next, the supplier uses the auction screen to input bid information on the supplier side computer 40 (step 209).
Bidding information is input based on a number of shares that can be obtained in advance, and bidding is performed at a bid price for each share.

  An example of the auction bidding screen viewed from the supplier side of the share auction is shown at 610 in FIG. In 610 of FIG. 6, the share split status 611 (share 1 = 60%, share 2 = 30%, share 3 = 10%), price rank 612 (acquireable share 50% to 70%, top price “993,000 yen” "The final bid price is" 995,000 yen "and the price ranking is" 3rd. "30% to 50% share available, leading price" 1,0966,000 yen ", final bid price" 1,0097,000 yen The price ranking is “2nd.” The market share is 10% to 20%, the top price is “1,197,000 yen”, the final bid price is “1,197,000 yen”, and the price ranking is “1st place”. ), Situation 614 ((> _ <), crown display) Next time share fluctuation price 613 (50% to 70% share available, “992,000 yen bidding will make 60% share”. 30% share available) 50%, leading price “1,096, 00 yen ", will be 35 percent share in the" 1,018,000 yen bid. "), And the like is shown.

  In the price rank 612, even if the price rank is “2nd place”, the supplier obtains an acquired share value of 30% with an acquirable share of 30% to 50% (in the situation 613, the crown (successful company) is displayed). This is because the share discount auction cannot be made with a plurality of obtainable shares. In other words, even if the supplier accessing this screen is “2nd place” with 30% to 50% share, the other suppliers are bidding at the top price with 50% to 70% share. In addition, since other suppliers are bidding for the top price with 30% to 50% of the share that can be acquired, even if the price rank is “2nd place”, the share is acquired with 30% to 50%. The emoticon (> _ <) shown in the situation 613 is unable to acquire a share because other companies are bidding at a lower price even though they are bidding with an acquirable share of 50% to 70%. Is shown.

Next, the input bid information is transmitted from the supplier-side computer 40 to the server 20 (step 210), and the bid information is received by the server 20 (step 211).
Next, in order to change the calculated share from the received bid information, each supplier is required to make a successful bid in each obtainable share, and even when the share has already been acquired. Calculate the bid price at the time of share change necessary to further increase the share. Then, the bid price at the time of share change and the share at the bid price at the time of share change are transmitted to the supplier computer (step 212).

For example, in the next share fluctuation price 614, “992,000 yen bidding makes the share 60%” is indicated as information necessary for making a successful bid with an acquirable share of 50% to 70%. This indicates a bid price “992,000 yen” necessary for this share and a calculated share “60%” when the price is bid.
Further, in the next share fluctuation price 614, information necessary for further acquiring a share in this share is shown as “35% share with a 1,018,000 yen bid”. This indicates the bid amount necessary to improve the current share of 30% and the calculated share in that case.

  The share change bid price and the share transmitted from the server 20 are received by the supplier computer 40 (step 213). When the buyer wants to change the share, he follows the instruction of the next share change price 614 or inputs bid information based on an inexpensive bid price (step 214). Then, the supplier-side computer 40 transmits bid information to the server 20 (step 215).

  The bid information (step 216) received by the server 20 is transmitted to the buyer computer 30 (step 217), and the bid information is received by accessing the auction screen on the buyer computer 30 computer (step 218). ) And confirm the bid information (step 219). The bid information may be received and confirmed at any stage after the auction is held.

  An example of an auction status monitoring screen viewed from the buyer side of the share auction is shown at 710 in FIG. In 710 of FIG. 7, the bid situation 711 of seller 1 (acquired share value “60%”, successful bid “bid price 980,000 (1st place)” with share 1), and bid situation 712 of seller 2 (acquired share value “25 % ”, Successful bid with share 2 (bid price 1,020,000 (1st place)), bid status of seller 3 (acquired share value“ 15% ”, successful bid with share 3“ bid price 1,063,000 (1 ))), Share share status 714, etc. are shown.

Next, the server 20 determines whether or not the auction end date / time entered in the auction definition information has come (step 220). The bid information can be input (step 214) until the auction end date and time.
When the auction end date / time is reached, the auction ends.

  Hereinafter, the flow of bid data processing in the auction auction will be described with reference to FIG. The procedure of bid data processing is mainly executed by the processing unit according to a predetermined program stored in the storage unit in the server 20.

First, a user who is a buyer inputs auction definition information using the auction registration screen (step 801).
Here, the auction definition information refers to definition information such as the auction date and time, the auction type, the target product information, and the selected supplier. Definition information similar to the auction definition information described with reference to FIG. 3 is set.

  An example of the registration screen for the auction type auction is shown at 910 in FIG. In 910 of FIG. 9, the inputted auction definition information includes auction type 911 (auction type), auction interval 912 (first time: 300 seconds, and thereafter: 60 seconds), and the like. The auction interval 912 is an auction type (escalator type auction), and the time until the next set price is raised is set. “First time” is the time from the start of the auction to the first price rise in seconds. Set in units. “After” sets the time at the next set price after the second time in seconds.

An example of a product information registration screen in the auction type auction is shown at 1010 in FIG. In 1010 of FIG. 10, the input product information includes a product name 1011 (“copy paper A4”), a quantity unit 1012 (quantity “1”, unit “case”), a target price 1013 (“3500” yen), a bid There are a lower price entry field 1014 (“4100” yen), a detailed auction price 1015 (designated prices to be auctioned are 4000 yen, 3900 yen,..., 3400 yen) and the like.
Although not shown, on the auction registration screen, a supplier or the like as an auction inquiry target is input.

  Next, the auction definition information input by the buyer is transmitted from the buyer-side computer 30 to the server 20 (step 802). The definition information (step 803) received by the server 20 is stored in the storage unit, and the user as a supplier accesses the auction screen generated by the bid data processing system on the supplier side computer 40, whereby the supplier side computer 40 (step 804).

  Next, the supplier receives the auction definition information (step 805), and confirms the auction definition information using the auction screen (step 806).

  Next, it is determined whether or not the auction opening date entered in the auction definition information is reached. When the auction opening date is reached, a holding mail is transmitted from the server 20 (step 807), and the holding mail is received by the supplier computer 40. (Step 808). In step 807, the hosting mail may be transmitted at an arbitrary timing by the buyer operating the hosting mail.

  Next, the supplier uses the auction screen to input bid information on the supplier computer 40 (step 809).

In the case of auction, the winning bid price decreases according to the time set at the auction interval.
The bid information by the supplier is information indicating that a bid is made at a bid price displayed on the web page. The information is transmitted from the supplier side computer 40 to the server 20 by pressing a “bid button” on the web page when the set price that the supplier wants to bid is displayed on the web page of the supplier side computer screen. .

  Next, the input bid information is transmitted from the supplier-side computer 40 to the server 20 (step 810), and the bid information is received by the server 20 (step 811). Then, the bid information received by the server 20 is further auctioned according to the time set at the auction-off interval. The bid price is further transmitted from the server 20 to the buyer computer 30 (step 812). The buyer-side computer 30 receives the bid information by accessing the auction screen (step 813), and the buyer confirms the price that has been further lowered.

  When the buyer bids again at the lower price, the bid information is information indicating that the bid will be offered at the displayed lower price by pressing the “bid button” on the web page as described above. (Step 814), the bid information is transmitted from the supplier computer 40 to the server 20 (step 815).

  Then, the bid information (step 816) received by the server 20 is transmitted to the buyer computer 30 (step 817), and the bid information is received by accessing the auction screen on the buyer computer 30 (step 818). The bid information is confirmed (step 819). The bid information may be received and confirmed at any stage after the auction is held.

  An example of an auction status monitoring screen viewed from the buyer side of the auction auction is shown at 1110 in FIG. In 1210 of FIG. 11, a status bar 1111, a set price 1112 (“89000 yen”), a bid price 1113 (seller 1 is “92000” yen, 1st place, seller 2 is “93000 yen”, 2nd place, and seller 3 is “ "93,000 yen" and the second place.) Etc. are shown.

Next, the server 20 determines whether or not the auction end date / time entered in the auction definition information has come (step 820). The bid information can be input (step 814) until the auction end date and time.
When the auction end date / time is reached, the auction ends.

  Hereinafter, the flow of the bid data processing for the auction will be described with reference to FIG. The procedure of bid data processing is mainly executed by the processing unit according to a predetermined program stored in the storage unit in the server 20.

First, a user who is a buyer inputs auction definition information using an auction registration screen (step 1201).
Here, the auction definition information refers to definition information such as the auction date and time, the auction type, the target product information, and the selected supplier. Definition information similar to the auction definition information described with reference to FIG. 3 is set.

  An example of the registration screen of the auction type auction is shown at 1310 in FIG. In 1310 of FIG. 13, the inputted auction definition information includes an auction type 1311 (auction type), auction interval 1312 (first time: 300 seconds, and thereafter: 60 seconds), and the like. Auction interval 1312 is a bid type, and the time until the price is increased to the next set price is set. “First time” is the time from the start of the auction to the first price increase in seconds. “After” sets the time at the next set price after the second time in seconds.

An example of a product information registration screen in the auction type auction is shown at 1410 in FIG. In 1410 of FIG. 14, the input product information includes a product name 1411 (“copy paper A4”), a quantity unit 1412 (quantity “1”, unit “case”), a target price 1413 (“3500” yen), a bid There are an increase price input field 1414 (“4100” yen), a detailed bid amount 1415 (designated prices to be auctioned are 4000 yen, 3900 yen,..., 3400 yen) and the like.
Although not shown, on the auction registration screen, a supplier or the like as an auction inquiry target is input.

  Next, the auction definition information input by the buyer is transmitted from the buyer-side computer 30 to the server 20 (step 1402). The definition information (step 1403) received by the server 20 is stored in the storage unit, and the user as a supplier accesses the auction screen generated by the bid data processing system on the supplier side computer 40, whereby the supplier side computer 40 (step 1404).

  Next, the supplier receives the auction definition information (step 1405), and confirms the auction definition information using the auction screen (step 1406).

  Next, it is determined whether or not the auction opening date entered in the auction definition information is reached. When the auction opening date is reached, a holding mail is transmitted from the server 20 (step 1407), and the holding mail is received by the supplier computer 40. (Step 1408). In step 1407, the hosting mail may be transmitted at an arbitrary timing by the buyer operating the hosting mail.

  Next, the supplier uses the auction screen to input bid information on the supplier computer 40 (step 1409).

In the case of auction, the winning bid price increases according to the time set at the auction interval.
The bid information by the supplier is information indicating that a bid is made at the bid price displayed on the web page. The information is transmitted from the supplier side computer 40 to the server 20 by pressing a “bid button” on the web page when the set price that the supplier wants to bid is displayed on the web page of the supplier side computer screen. .

  Next, the input bid information is transmitted from the supplier-side computer 40 to the server 20 (step 1210), and the bid information is received by the server 20 (step 1211). Then, the bid information received by the server 20 is further auctioned according to the time set at the auction interval. The auctioned price is further transmitted from the server 20 to the buyer computer 30 (step 1212). The buyer-side computer 30 receives the bid information by accessing the auction screen (step 1213), and the buyer further confirms the bid price.

  When the buyer bids again at the auctioned price, he / she presses the “bid button” on the web page as described above to bid information at the bid price displayed. (Step 1214), and the bid information is transmitted from the supplier computer 40 to the server 20 (step 1215).

  The bid information (step 1216) received by the server 20 is transmitted to the buyer computer 30 (step 1217), and the bid information is received by accessing the auction screen on the buyer computer 30 (step 1218). The bid information is confirmed (step 1219). The bid information may be received and confirmed at any stage after the auction is held.

  An example of an auction status monitoring screen viewed from the buyer side of the auction is shown in FIG. In 1510 of FIG. 15, there is no display in the status bar 1511, the set price 1512 (“89000 yen”), and the bid price 1513. This indicates that there is no bid at the set price “1512 (16,000 yen)” displayed because the initial bid price is the winning bid price in the auction.

Next, the server 20 determines whether or not the auction end date / time entered in the auction definition information has come (step 1220). The bid information can be input (step 1214) until the auction end date and time.
When the auction end date / time is reached, the auction ends.

Hereinafter, the flow of bid data processing in a multi-auction will be described with reference to FIG.
The multi-auction is an auction in which a plurality of items and a plurality of items are bid. As a multi-auction, three types of auctions can be set: a detail bid type, a multi-item bid type, a distributed or a batch competitive bid type.
The detail bid type is used when the target item is one item and the price information of the detail and a plurality of price information are bid together. This makes it possible for each supplier to confirm which details are competitive during bidding.
The multi-item bidding type is used when there are a plurality of target items and bids for the plurality of items are performed simultaneously.
The distributed or batch competitive bidding type is used when there are a plurality of target items and a plurality of items are distributed and ordered to one company or a plurality of companies.
The procedure of bid data processing is mainly executed by the processing unit according to a predetermined program stored in the storage unit in the server 20.

First, a user who is a buyer inputs auction definition information using an auction registration screen (step 1601).
The auction definition information refers to definition information such as auction opening date and time, auction type, target product information, and selected supplier. Although not shown, it is possible to input a multi-auction, or a detailed bid type, a multi-item bid type, a distributed or a collective competitive bid type, etc., which are more detailed as an auction type.

  An example of a registration screen for a multi-item type auction is shown at 1710 in FIG. In 1710 of FIG. 17, the product information 1711 of the second item is added in addition to the product information shown in FIG. The product information added here is the same as the input item of the product information shown in FIG.

  Next, the auction definition information input by the buyer is transmitted from the buyer-side computer 30 to the server 20 (step 1602). The definition information (step 1603) received by the server 20 is stored in the storage unit, and the supplier user accesses the auction screen generated by the bid data processing system on the supplier computer 40, thereby providing the supplier computer. 40 (step 1604).

  Next, the supplier receives the auction definition information (step 1605), and confirms the auction definition information using the auction screen (step 1606).

  Next, it is determined whether or not the auction opening date entered in the auction definition information is reached. When the auction opening date is reached, a holding mail is transmitted from the server 20 (step 1607), and the holding mail is received by the supplier computer 40. (Step 1608). In step 1607, the hosting mail may be transmitted at an arbitrary timing by the buyer operating the hosting mail.

  Next, the supplier uses the auction screen to input bid information on the supplier computer 40 (step 1609).

Next, the input bid information is transmitted from the supplier-side computer 40 to the server 20 (step 1610), and the bid information is received by the server 20 (step 1611).
Based on the bid information, the server 20 compares the sum of the minimum bid prices for each of the plurality of items (or details) with the price of the collective bid (or single item bid in the case of detailed bids), and Calculate the price needed to make a successful bid.
For example, for the target items A, B, and C, supplier 1 inputs a bid price of A = 50 yen, B = 100 yen, and C = 150 yen, and supplier 2 applies to A, B, and C. When a bid price of 250 yen is input as a collective price, the supplier 1 calculates a successful bid price of 249 yen for A, B, and C as a whole in order for the supplier 1 to make a successful bid.
Further, when the supplier 1 inputs bid prices of A = 50 yen, B = 100 yen, and C = 90 yen, the server 20 sends A, B, C to the supplier 2 in order for the supplier 2 to make a successful bid. The total successful bid price of 239 yen is calculated.

  The calculated successful bid price is further transmitted from the server 20 to the buyer computer 30 (step 1612). The buyer side computer 30 receives the bid information by accessing the auction screen (step 1613), and the buyer further confirms the bid price.

  When the buyer bids again, the buyer inputs new bid information (step 1614), and transmits the bid information from the supplier computer 40 to the server 20 (step 1615).

  Then, the bid information (step 1616) received by the server 20 is transmitted to the buyer computer 30 (step 1617), and the buyer computer 30 receives the bid information by accessing the auction screen (step 1618). The bid information is confirmed (step 1619). The bid information may be received and confirmed at any stage after the auction is held.

Next, the server 20 determines whether or not the auction end date / time entered in the auction definition information has come (step 1620). The bid information can be input (step 1614) until the auction end date and time.
When the auction end date / time is reached, the auction ends.

Note that the buyer or server 20 may execute a step of reducing the number of suppliers in Step 1611. In this case, when the server 20 automatically performs processing, the buyer determines the selected supplier from the lowest bid price for each target item by setting the maximum number of suppliers in the auction definition information in advance. Suppliers that exceed the maximum number of suppliers according to price ranking can be excluded from the auction.
When the distributed order type is selected, it is also possible to select the minimum number of suppliers in the auction definition information in advance and place a distributed order with a predetermined minimum number of suppliers by the processing of the server 20. In this case, even if there is only one supplier who bids at the lowest price for all items, if the minimum number of suppliers is 2, the supplier who offered the bid price of the second tag is selected as the winning supplier for any item You may do it.

Further, in step 1609, the supplier may make a bid by combining any of the plurality of items when performing the detailed bidding or the multi-item bidding. That is, when the target items are A, B, and C, the supplier 1 bids by combining A and B with one item (or details), or combines A and C as one item (or details). It is possible to bid.
By enabling bidding through such arbitrary combinations, suppliers can bid on items that can maximize their cost merit, and buyers can lower their prices at lower cost. Ordering is possible.

  In the multiple item bid type and the detailed bid type, the multiple item bid type term “all items”, the detailed bid type term “single item”, and the multiple item bid type term “item” Each type of term “detail” corresponds. Therefore, when there is an explanation of the above-mentioned terms of the multi-item bid type in the above, the same applies to the corresponding terms of the detailed bid type.

  As described in detail above, in the bid data processing system according to the present invention, it is possible to place a distributed order in consideration of the volume merit and risk by the share split auction, and further, it is less than the competitive price between suppliers by the carry-down / advance auction. Bidding on items that tend to offer low prices to suppliers has become possible through ordering at multiple bid prices and multi-auctions.
