Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bidding joint sales method using a computer network, and more particularly, receives bidding information of a seller using a computer network such as the Internet, and presents optimum sales conditions. A seller was selected, a public notice of bidding was made on the Internet, and consumers were to bid, and among the bidders, bid prices and bid volumes within a range that could benefit both the seller and the consumer were presented. Only bidders are decided to be successful bidders to make joint purchases, and only bidders who submit bid prices and bid quantities that meet the shopping mall sales policy decision conditions are decided to be successful bidders and sell goods. The present invention relates to a product bidding-type joint selling method in which a consumer can obtain an effect as if jointly purchased.

[0002]

2. Description of the Related Art At present, auctions that are popularly performed on the Internet are conducted in such a manner that sellers auction goods (types and quantities of goods) and make a bid to the highest bidder. You. Another auction system is a so-called "reverse auction" in which a consumer announces a desired product and quantity, and purchases the product from a seller who has offered the lowest price (or the appropriate price selected by the consumer). It is a method.

[0003] One of the Internet electronic commerce systems that have been widely used recently is joint purchase. Unlike online shopping malls, in which consumers select certain products and then select them, a joint purchase is a process of recruiting purchasers for a particular product and, when the number of purchasers increases, directly connecting to the producer and lowering the cost. This is a method of trading goods at a price. In such joint purchasing, the seller presents joint selling quantity and price, solicits consumers who want to purchase the product through the Internet, and desires to purchase only joint selling quantity (or excess quantity). When people come together, a transaction is made. According to such joint purchasing, the seller can increase the selling price by lowering the sales unit price by selling in large quantities, and the consumer spends a certain amount of time in recruiting purchase applicants, so the point of purchase is delayed. However, since there is an advantage that a commodity can be purchased at a low price, such a joint purchasing method is widely used.

However, since the joint purchase on the Internet is a method in which consumers follow the unilaterally determined quantity and price, there is a limit to the choice of the consumer, and the target order quantity (joint sales quantity) is limited during the bidding period. If not received, the joint purchase may not be made.

In recent years, an initial supply price has been determined, and it is necessary to sell products at a low price to consumers so that the selling price becomes lower as the number of purchasers increases. This has led to the emergence of a co-sales system that increases sales volume by inviting more consumers to participate. Even in such a joint sales system, the consumer can only determine the desired purchase quantity, and cannot directly present the bidding price himself, but the price unilaterally determined by the seller (initial price and price). There is a drawback that it depends only on the bidding quantity (discount price). In addition, from the standpoint of the seller, regardless of the sales policy of the seller, since it is necessary to conduct transactions with the entire bidding consumer according to predetermined criteria, it is not possible to maximize profits (for example, The higher the volume, the lower the price, and as a result, it trades almost at the cost of production, so the increase in the bidding volume is not necessarily proportional to the profit).

[0006] Therefore, the above-mentioned joint purchasing and discount joint purchasing based on quantity increase are seller-led, and more precisely, they are not bidding (or auctioning) in that consumers can select a bidding price. It is merely a matter of recruiting buyers and selling large quantities of goods. In other words, consumers have no right to purchase goods at the price they choose, but only have to follow a price unilaterally determined by the seller depending on the number of buyers, or the consumer's price selection authority or There was no price predictability.

[0007] In addition, the Internet auction is based on a time base (ti
In the sales strategy of mevalue), a fixed number of products are auctioned, and only consumers who offer a price higher than the highest auction price to date can participate in the auction. In this respect, the auction has the disadvantage that the consumer only has the possibility of price selection and the quantity is limited to the range of prices offered by the seller.

[0008]

SUMMARY OF THE INVENTION The present invention focuses on this point. In electronic commerce on the Internet, many buyers select a bidding price and a bidding quantity and bid. Offers a method to select and trade only bidders that meet the conditions presented by the seller and a method to select and trade only bidders that meet the sales policy decision conditions presented by the service operator try to. In other words, a sales system that combines bidding and joint purchasing on the Internet that benefits both sellers and buyers, and that provides consumers with goods at low prices, An attempt is being made to provide a sales system that combines online bidding and joint purchasing so as to satisfy the sales policy of the dealer.

Accordingly, an object of the present invention is to select only bidders who meet the sales conditions presented by the seller in a transaction method on the Internet that announces the bid for the product to be sold and allows the consumer to bid. And provide a way to co-sell.

[0010] Another object of the present invention is to pay attention to the fact that when the sales volume increases, the price can be reduced from the standpoint of the seller. It is an object of the present invention to provide a bidding joint selling method using a computer network in which bidding is performed by selecting only bidders conforming to the seller's sales policy according to a specific method as successful bidders.

[0011] Still another object of the present invention is to select only a seller who presents the best condition to a consumer in the case of a large number of sellers of the same product in electronic commerce on a computer network such as the Internet. The purpose of the present invention is to provide a bidding-type joint selling method in which a bid is made.

Still another object of the present invention is to provide a bid-type joint selling method in which bidders who are closest to the winning bid are extracted and joint incentives are provided in joint selling by bid / bid on a computer network. It is.

[0013]

According to the present invention, there is provided a commodity bidding type joint selling method using a computer network for achieving the above object of the present invention, comprising: a web server having a member database and a seller / bid information database;
A bid bidding method using a computer network comprising a client computer and a connection channel connecting the client computer and the bid server, wherein the web server receives bid information received from a seller and stored in a seller / bid information database. Determining the bidding information comprising at least one of a maximum supply unit price, a staircase amount as a discount amount due to an increase in the sales volume, a bidding price according to the sales volume, and a maximum supplyable volume. A bidding announcement step of providing bidding product information and the bidding information on a computer network, and a web server receiving bidding information including a bidding price and a bidding quantity transmitted by one or more clients using the connection channel, A bidding stage in which at least one is stored in the database; Determining a successful bid price and a successful bid quantity based on bid information received and stored during the bidding period, and a web server presenting a bid price higher than the successful bid price and selling the successful bidder. And a joint selling phase in which joint transactions are made between the parties.

[0014] The determination of the successful bid price and the successful bid quantity is based on the fact that the total number of bidding quantities for which a price within a range between the highest supply unit price and the closest bidable price below a predetermined bid price is presented at the bid price is determined as the bidable price. Among the bidable prices that are equal to or more than the corresponding sales volume, the lowest bidable price is determined as the successful bid price, and the total number of bids between the highest supply unit price and the successful bid price is determined as the successful bid volume.

The bidding information received from the seller by the web server includes a seller's personal information, a sold product, a maximum supply unit price, a minimum supply unit price, and a minimum unit price supply lower limit which is a lower limit of the number of items that can be supplied at the price. It consists of one or more of the following: staircase price according to quantity, maximum available quantity, and sales quantity. In the case where two or more sellers are bidding on the same product, the web server may further include a seller selection step of selecting the seller with the highest staircase price as the final seller. it can.

The client may arbitrarily select a bidding price and a quantity. The bidding price may be selected from a bidding price according to the sales quantity designated by the web server or the seller. The quantity may be arbitrarily selected by the client.

In order to increase the participation of the client, the prize, cash, securities or cyber money, coupons, gift certificates are provided to the successful bidders who have offered the bid price closest to the successful bid price. A step of providing an incentive, such as discounting and increasing the purchase commodity price, may be further provided.

Further, even after the bidding / bidding is completed, the web server receives an additional purchase intention as to whether the unsuccessful bidders among the bidders and other clients are to purchase products corresponding to the winning bid price. In addition to successful bidders, clients who have indicated their intention to make additional purchases can be subject to joint purchasing.

In order to achieve the object of the present invention, another method of jointly selling goods by computer network using a computer network is to provide a client database and a bidding price (available price) for each step sales quantity (i) for a product to be bid.
A product using a computer network including a web server having a product / bid / bid information database storing bid product information including UPi) and production cost (c), a client computer, and a connection channel connecting the two. A bidding joint sales method,
The web server transmits the bidding information comprising at least one of a bidding available time, information on the bidding product, a maximum supply price (consumer price) of the bidding product, and a bidding price (UPi) according to each sales quantity. A bid notification step of providing a bid to one or more clients via a connection channel, and bidding information comprising a bid price and a bid quantity transmitted by the one or more clients through the connection channel is received by a web server and stored in one or more of the databases. Bidding stage, and the web server checks the sales policy decision conditions entered and stored by the bidding joint sales service operator,
Deciding a final bidding price and a bidding volume based on bidding information received and stored during the bidding period, and the web server sends a bidding bidder having a bidding price higher than the final bidding price to the bidding bidder. And a joint selling stage for performing a predetermined action of jointly selling the product, wherein the sales policy determining condition is that at least one of the profit priority item and the sales amount priority item has a weight value (2 The sum of the weights assigned to the items is determined by assigning 1), and the final successful bid price is determined according to the sales policy determination condition, and the bid price (UP) closest to a predetermined bid price from the highest supply unit price is determined.
The total bid volume (qi) of the bidding volume, which is the bid price that is the amount up to and including i), is equal to or more than the stair sales volume (i) corresponding to the bidding price. One is determined, and the final successful bid quantity is determined as the total bidding cumulative quantity from the highest supply unit price to the final successful bid price.

The above explanation corresponds to the case where the merchandise bidding joint sales service operator is a direct manufacturer / seller who directly manufactures and sells the merchandise. Let the weight of the item be a (0 ≦ a
When ≦ 1), the opportunity loss cost OPi (= the highest profit (m
ax (yi))-total profit (yi) at the bid price
Is the highest profit (max (yi)) * (1-weighted value (a))
Among the possible bid prices included in the above, the highest bid price having the largest cumulative bid quantity (sales quantity; qi) is determined as the final successful bid price.

[Equation 1] yi = (UPi-c) * qi [Equation 2] OPi = max (yi) -yi In the above equation, yi is the total profit at each possible bid price, UP
i is the bid price, c is the production cost of the product, qi is the cumulative bid quantity at the bid price, max (yi) is the maximum profit,
OPi means opportunity loss cost.

On the other hand, when the above-mentioned merchandise bidding joint sales service operator is not a direct manufacturer and seller directly manufacturing and selling the product, but an intermediary distributor that mediates transactions between the seller and the consumer. Prior to the above-described bid notification stage, the web server receives the highest bid price (consumer price; consumer price) based on the bid information received from one or more sellers and stored in the product / bid / bid information database. max
P), minimum supply unit price (minP), minimum unit supply minimum quantity (n) that is the lower limit of the quantity that can be provided at the minimum supply unit price,
Staircase amount (s
p), bid price based on sales volume (i) of each stair (UP)
i) and determining bid information comprising one or more of the maximum suppliable quantities.

When the merchandise bidding joint sales service operator according to the present invention is an intermediary distributor, the final successful bid price is determined by the following method. When the weight of the profit priority item is a (0 ≦ a ≦ 1), the opportunity loss cost OPi = (maximum profit (max (yi ))-
The total profit (yi) at the possible bid price is the highest profit (ma
x (yi)) * (1−weighted value (a)), among the possible bid prices included in the bidding price (cumulative bidding quantity (sales quantity; qi)), the highest bid price is determined as the final successful bid price. You.

[Equation 3] yi = UPi * qi * r + (UPi-oi) * qi [Equation 4] OPi = max (yi) -yi In the above equation, yi is the total profit at each possible bid price, UP
i is the bidding price, qi is the cumulative bidding quantity (sales quantity) at the bidding price, r is the profit commission rate for the total sales (UPi * qi), and oi is the unit price of the product when the sales volume is received from the seller. (Order unit price), max (yi) means maximum profit, and OPi means opportunity loss cost.

Further, in both cases where the service operator of the present invention is a direct manufacturer / distributor or an intermediary distributor,
The method may further include the following steps or methods.
In the bidding information of the client, the bidding price is such that one of the bidding prices for the minimum salable quantity determined by the commodity bidding joint sales web server is selected, and the bidding quantity is arbitrarily determined by the client. You can choose. In other words, the bid possible price (UPi) is provided in the bid notice, and one of the prices (UPi) can be selected, or the client can arbitrarily determine. When arbitrarily determined, the web server determines the bid price (UPi) closest to (below) the bid price presented by the client as the bid price of the client.

In the same manner as in the first embodiment, among the successful bidders, a predetermined incentive is provided to the successful bidder who has offered the bid price closest to the final successful bid price, or a client having an additional purchasing intention is further recruited. May include the step of:

As will be described in detail in the following embodiments, the seller or distributor sets a profit-priority sales policy to select the highest bidable price (UPi) based on the result of the bidding of the consumer. It is possible to establish a sales policy that prioritizes sales volume, where sales volume is the highest even if profits decrease somewhat. As described above, the seller or the distributor assigns a value of 0 to 1 to the profit priority item or the sales volume priority item according to the current state of the bidding of the consumer for each stage sales volume (i) and the corresponding bidable price (UPi) stage. Weight (a is given to other items), and the bid price corresponding to the sales policy determined by the seller or distributor is finally determined by the weight. It is determined as the winning bid price.

The "commodity" which is the object of the present invention is not necessarily limited to a specific commodity, but all goods which can be subjected to electronic commerce using the Internet, for example,
Must be understood in a broad concept including fluid goods, intangible information, services such as travel, etc. In particular, it is determined that a commodity that is more likely to be discounted due to an increase in the supply amount is more suitable for the present invention.

The central processing module is linked to each of the modules, and receives, stores and manages the goods to be bid, bid / successful bid information and / or client bidding information. Then, bidding information including the amount of the stairs (sp), the quantity of the stairs sold (i) and the bidding price (UPi) for each is generated and publicized for bidding, and the final bidding price matching the conditions is determined according to the bidding result and the above-mentioned mathematical formula. , Successful bid quantity, successful bidder,
Each module is controlled to determine a winner or the like.
The central processing module, according to a method described below, determines the bidding price (UPi) for each stair sales volume (i) according to the weight (a) given to the profit priority item or the sales volume priority item, which is the core technology of the present invention, and the bidding state. Among them, the amount corresponding to the sales policy condition by the above-mentioned mathematical expression in the bidable price (UPi) in which the total accumulated bid quantity (qi) at the bidable price exceeds the staircase sales quantity (i) at that time. Must be determined as the final successful bid price, and various procedures such as selecting a successful bidder must be performed accordingly. Furthermore, when the service operator of the present invention is an intermediary distributor that receives goods from sellers and sells them to consumers, the web server can provide one or more sellers in addition to the above-described final bid price determination function. , A minimum supply price (maxP), a minimum supply price (minP), a minimum unit price supply minimum quantity (n), which is the lower limit of the supply amount that can be provided at the minimum supply price, according to the bid request information. It must be able to calculate and store the maximum suppliable quantity, the staircase amount (sp), the bidding price (UPi) for each staircase sales quantity (i), etc.

Such a web server is called Dos (Dos).

The following description of FIG. 3 to FIG. 5 corresponds to the case where the service operator according to the present invention is an intermediary distributor, and if the service operator is exactly a manufacturer / seller, the bid request information is sold. Instead of receiving from the seller or selecting the final bidder, the necessary bidding information may be easily generated from the material directly input by the seller, and publicized.

FIG. 3 is a flowchart of a resource (Source) performed between components in the bidding joint selling method on the Internet according to the present invention. First, 1) the web server receives bid request information from one or more sellers, and after selecting the final seller and calculating the bid information, announces the bid. 2) When the client bids according to the notice of the tender, 3) The web server determines the successful bidder from the received bid information. Then, 4) selectively announce the fact of the successful bid or
By sending an e-mail asking the unsuccessful bidder if he / she wants to purchase the product at the successful bid price, recruit additional purchase applicants who have an intention of additional purchase, and final joint buyer (successful bidder + additional purchase applicant) To determine. 5) The web server transmits information on the final buyer to the seller, and 6) delivers the goods to the final buyer after settlement. Of course, in this case, the settlement can be performed through the Internet, and the web server, the seller can use his own payment system or an external payment agent server.

FIG. 4 is a flowchart of a bidding joint selling method on the Internet according to the first embodiment of the present invention in which the sales amount is prioritized without considering the sales policy of the service operator. Bid information received from sellers at (bid product type, maximum supply unit price, minimum supply unit price, minimum supply unit
Store and manage stair price, bid period, etc. (S4)
1). It is determined whether there are two or more bid applicants received in the predetermined period (S42). If there are two or more sellers who wish to bid for the same product, the seller with the highest staircase price is final bid. (S43). The web server calculates the price of the stairs, the bidding price per sales quantity, etc. from the bid information of the final bidder, and announces the bidding via the Internet (S44). The client specifies the bidding price and bid quantity (purchase desired quantity) according to the notice of bidding and bids, and the web server receives the bidding information of the client and stores it in the seller / bidding information database and the member database (S45). After the bidding period has elapsed, the web server determines the winning bidder, the winning bid quantity and the winning bid price among the bidders (S47).
A notice of bid is issued (S50 '), and the process ends. If there is a successful bidder, the unsuccessful bidder who did not make a successful bid and the other members are notified of the fact of the successful bid for the product, and recruit additional purchasers for a predetermined period (S49). When the final purchaser (successful bidder + additional purchaser) is determined, the fact is notified to the seller, and settlement and delivery are performed so that joint sales are performed (S50).

Although not shown, the method may further include the step of selecting, among the successful bidders, the bidder who bids at the price closest to the successful bid price as a winner and providing a predetermined incentive. Bid price, successful bidder, successful bid price,
The successful bid quantity and winner selection will be described in detail below with reference to FIGS.

FIG. 6 shows an example of a website that provides a bidding joint sales service according to the present invention, and particularly shows a web page where a seller can apply for a bid request. The seller enters personal information such as the trader's name, contact information, address, etc., the name of the product to be bid, the highest supply unit price (consumer price), the lowest supply unit price, the minimum supply unit minimum supply quantity, the maximum supply quantity for the bid period ,
Enter or select the bid period. Alternatively, a stair amount, which is a discount amount due to an increase in the sales volume, may be directly input.

The input bidding information is received by the web server and stored and managed in the database. If the seller does not provide the stair price, the web server calculates the stair price and stores it together. If there are two or more bidders, the price of the final bidder selected among them is calculated and stored.

FIG. 7 is a table showing a comparison in a case where the sellers who sell the same product are four dealers (sellers 1 to 4). The maximum supply unit price of 320,000 yen, 290,0
A minimum supply unit price of 00 to 310,000 yen, a minimum unit supply minimum quantity of 5 to 10 pieces, a maximum supply quantity of 50 to 100 pieces, and the like are specified. The staircase amount, which is the discount amount based on the sales amount (that is, the price that is discounted each time the sales amount increases by one), is determined by the following equation.

Stair price = (highest supply unit price-lowest supply unit price) / (lowest unit price supply lower limit quantity-1) According to the above equation, the staircase amounts of sellers 1-4 are 4,000 yen, 3,333 yen, respectively. 2,500 yen, 5,000
Since it is 0 yen, the seller 4 indicating the highest staircase amount is selected as the final bidder.

[0048] Once the final bidder is selected, the supply unit price and the bidable price based on the sales volume of the bidder are determined. The bidable price is determined as a price obtained by multiplying the seller's supply unit price by a certain ratio, and is used for providing an incentive to be paid to a winner described later. However, for example, when the service of the present invention is used free of charge or when the incentive is not provided by winning, the supply unit price and the bidable price can be determined to be the same price (second embodiment; FIG. 9).

In this embodiment, the possible bid price is 1 of the supply unit price.
It is determined to be 01%, and as shown in FIG. 8, the supply unit price and the bidable price according to the sales quantity are shown in the table. FIG. 10 shows a web page that provides information about the bidding product and allows the client to respond to the bidding, where the bidding product name, seller, maximum supply unit price (consumer price), bidding period,
The detailed product information and the like are displayed, and below it, the consumer can select a bidding price and a bidding quantity to bid. At this time, the determined bid price per sales quantity may be provided in a pull down menu, and one of the prices may be determined or may be arbitrarily input. The bidding quantity is arbitrarily determined by the client. The web server receives the bidding information input in this way, stores it in a database, and uses the bidding information as basic data when determining a successful bidder after the bidding period has elapsed.

At this time, the client has previously subscribed as a member, and the web server uses the "cookie" function of the client web browser to connect to the web server and grasp the identity of the member at the same time. It is also possible to recognize the member by logging in after inputting the ID and secret number, so that the client does not need to input personal information every time bidding. To However, it is not always necessary to operate with a membership system in which members are registered in advance, and if operated with a non-member system, input necessary information such as personal information of the bidder, financial information, etc. at the time of bidding. There must be.

FIG. 11 shows a method of selecting the highest bidder, the highest bid price, the highest bid quantity, and / or the winner in the first embodiment of the present invention (priority to sales volume without considering the sales policy). It is a figure for explaining. From the table as shown in FIG. 8, the bidding status (customer name / bidding quantity) is calculated for each sales quantity, and the bidding price in the range between the highest selling price and the predetermined bidding price is presented as the bidding price. Among the bidable prices whose total number is equal to or more than the sales volume corresponding to the bidable price, the lowest bidable price is determined as the successful bid price, and the total cumulative number of bids between the bid prices is determined as the successful bid volume.

At this time, if the client arbitrarily inputs the bidding price, the bidding price of the customer is set to the closest price (sales quantity) among the bidding prices that are equal to or less than the input bidding price. Will be included. For example, 310,
The bid of the customer who presented 000 yen at the bidding price is included in 308,050 yen (sale quantity of 4) in the bidding price.

The method for determining the winning bid price and the winning bid quantity will be described with reference to FIG. 11. The bidable price having a cumulative bidder equal to or greater than the corresponding sales quantity is 308,050 yen (cumulative bid quantity 5> the selling quantity 4). , 303,000 yen (cumulative bidding quantity 6> the relevant sales quantity 5), 297,950 yen (cumulative bidding quantity 8> the relevant sales quantity 6), 292,900 yen (cumulative bidding quantity 8> the relevant sales quantity 7), 287 , 850 yen (cumulative bidding quantity 8 ≧ the sales quantity 8), and the lowest price of 287,850 yen is determined as the final successful bid price, and the total cumulative bidding quantity at this time, 8 pieces, is determined as the bidding quantity. Is done.

When determined in this way, the consumer can purchase at the lowest price among the prices that can be offered by the seller, and the seller can sell the goods in large quantities.
Both benefit.

FIG. 12 shows successful bid information when the final successful bid is made. The successful bid quantity (eight pieces) and the successful bid price (287,
850 yen), the customer B who has presented the bid price closest to the successful bid price is selected as the winner, and a predetermined incentive is provided. In the present embodiment, the difference between the seller's total supply price and the total successful bid price, that is, (287,850-
285,000) x 8 = 22,800 yen will be provided to the winners as an incentive. As a method of providing the prize money, a method such as cash payment, provision of cyber money, discount of commodity price, and the like can be used, but is not limited thereto.

When such a method of providing incentives by winning is introduced, compared with the conventional joint purchase or the bidding joint purchase of the system of the present invention without providing incentives,
Consumer interest or participation can be dramatically increased, and as a result more bidding for consumers can be induced. This allows consumers to co-purchase goods at lower prices, and if this fact is widely known, it can further increase the participation of consumers and increase the visibility of such services → consumption The synergistic effect of increasing participant participation → falling prices is expected to eventually enable joint sales in a much larger quantity than the conventional joint purchasing method.

In addition, as described above, in order to recruit additional purchase applicants other than the successful bidder, the web server notifies the website of the successful bid items or sends a mail or the like to the unsuccessful bidder to determine the fact of the successful bid. Informing, it is possible to recruit additional purchasers who purchase the product at the successful bid price.

When the final buyer including the successful bidder and the additional purchaser is determined, the web server transmits information on the final buyer and successful bid information (successful bid price, successful bid quantity per buyer, etc.) to the seller, The seller receiving this collectively delivers the merchandise to the buyer. For the security of the transaction of the consumer, the web server can receive the delivery confirmation information of the consumer and transmit it to the seller again so that the settlement between the seller and the consumer can be made. In addition, the web server can provide a direct payment (agent) service. In such a case, the payment is received from the confirmed consumer (credit card settlement, electronic fund transfer, online deposit, etc.). (In a way). In other words, any conventional electronic commerce system can be applied to the transaction between the seller (intermediary distributor) and the consumer after the successful bidder is determined.

FIG. 5 is a flowchart of a bid-type joint selling method on the Internet according to the second embodiment of the present invention using a sales policy (a weight given to a profit priority or a sales volume priority item) designated by a service operator. , The web server stores bidding information received from one or more sellers (bid type, maximum supply unit, minimum supply unit, minimum supply unit quantity that can be sold at minimum supply unit, staircase amount, bid period, etc.) It is managed (S51). It is determined whether there are two or more bid applicants received during the predetermined period (S5).
2) If there are two or more sellers who wish to bid for the same product, the seller with the highest staircase price is selected as the final bidder (S53). The web server calculates the amount of the stairs (sp), the amount of the stairs sold (i) and the possible bid price (UPi) from the bid information of the final bidder and announces the bid through the Internet (S54). The client specifies the bidding price and the bidding quantity (the desired quantity to be purchased) according to the notice of bidding, and the web server receives the bidding information of the client and stores the bidding information in the merchandise / bid / bidding information database and the client database (S5).
5). After the bidding period has elapsed, the web server determines the final successful bid price, the successful bidder, the successful bid end, etc. according to the sales policy (the weight given to the profit priority or the sales volume priority item) input by the service operator (S57). If there is no successful bidder, a bid notice is issued (S61) and the process ends. If there is a successful bidder, the unsuccessful bidder who has not been awarded the bid and the other members are notified of the fact of the successful bid for the product, and recruiting additional purchasers for a predetermined period (S59). When the final purchaser (successful bidder + additional purchaser) is determined, the fact is notified to the seller, and settlement and delivery are performed so that joint sales can be performed (S60).

Although not shown, the method may further include a step of selecting a bidder who has bid at a price closest to the successful bid price among the successful bidders as a winner, and providing a predetermined incentive. .

The possible bid price, successful bidder, final successful bid price, successful bid quantity, and selection of the winner will be described in detail below with reference to FIGS. 13 and 14. FIG. 6 shows an example of a website for providing a bidding joint sale service according to the present invention, which is used in the same manner as in the first embodiment, and a detailed description thereof will be omitted.

The bidding information entered by the seller is received and received by the web server, and is stored and managed in a database.
If the seller does not provide the stair price, the web server calculates the stair price and stores it together. When there are two or more bid applicants, the stair price of the last bidder selected among them, the stair sales volume (i) and the bidable price (UPi) for each stair are calculated and stored.

As in the first embodiment, FIG. 7 is a table showing a comparison in a case where the sellers who sell the same product are four dealers (sellers 1 to 4). Supply unit price, minimum supply unit price of 290,000 to 310,000 yen, minimum unit supply quantity of 5 to 10 units and 50 to 1
The maximum supply quantity of 00 pieces and the like are specified. The stair price (sp), which is a discount amount based on the sales quantity (that is, a price discounted when the sales quantity increases by one), is determined by the following equation.

[Mathematical formula 5] Stair price (sp) = (maximum supply unit price maxP−minimum supply unit price minP) / (minimum unit price supply lower limit quantity n−1) According to the above equation, the stair price of sellers 1-4 is 4,000 yen, 3,333 yen, 2,500 yen, 5,000 yen respectively
Since it is 0 yen, the seller 4 showing the highest staircase amount is selected as the final bidder.

Once the final bidder is selected, the bidderable price (UPi) based on the staircase sales quantity (i) of the bidder
Is determined step by step. The bidable price (UPi) is determined as the maximum supply price (maxP)-(stair sales volume (i) -1) * stair price (sp). As shown in FIG. Given. As in the first embodiment, a price obtained by multiplying a supply price by a certain ratio for providing incentives may be used as UPi.

A web page for providing information on a bid product and allowing a client to respond to a bid and a bidding process using the web page are the same as those described in the first embodiment with reference to FIG.

FIG. 13 is a view for explaining a method of selecting core elements, ie, a successful bidder, a successful bid price, a successful bid quantity, and / or a winner in the second embodiment of the present invention, and FIG. 13 shows a service of the present invention. FIG. 14 corresponds to the case where the operator is a manufacturer / seller, and FIG. 14 corresponds to the case where the service operator is an intermediary distributor.

As shown in FIG. 13, the maximum supply unit price (maxP) of the product is 1,000,000 yen, the minimum supply unit price (minP) is 600,000 yen, the production cost (c) is 500,000 yen, A minimum unit price supply lower limit quantity (n), which is a lower limit quantity that can be provided at the minimum supply unit price, is given by 16. From such product information, the web server calculates a staircase amount (sp) of 26,666 yen according to the above-described formula, and calculates a bidding price (UPi) for each stair sales volume (i).
Calculate and store. The bidable price (UPi) is obtained by the following equation.

[Equation 6] Bidable price (UPi) = Maximum supply unit price (maxP) −
(Sales volume of stairs-1) * Amount of stairs (sp) The results of the bidding are displayed in columns 4 and 5 of the table shown in Fig. 13, the bidding status of each stage (4 columns) and the cumulative bidding up to each stage It is represented by the quantity (5 columns, qi). Based on such bidding results, the total revenue (yi) for each stage is UPi
* Calculated by qi. In this embodiment, when the stair sales volume (i) is 11, the highest profit (max (y)
i)) is determined to be 22,000,200 yen, and the opportunity loss cost (OPi) is calculated for each stage by the following formula.

[Equation 7] Opportunity loss cost (OPi) = maximum profit (max (yi))
-Total profit at each stage (yi) As can be seen from the above, the cumulative bidding volume for each stage (qi)
Is the bid-available price (UPi) at which the stair sales volume (i) is equal to or greater than that at that time. In the above embodiment, all the stages where the stair sales volume (i) is 7 or more are determined as the bid-available prices. You.

If the seller sets the weighting value (a) given to the profit priority item to 1 and inputs a profit priority sales policy that considers only profit to the web server, the above table is used. To maximize revenue (i
= 11) 73 is the possible amount of bid (successful bid) (UPi)
3,340 yen is selected as the final successful bid price, and the bidding quantity is 30 pieces in total. Conversely, when the seller sets the weighting value (a) given to the profit priority item to 0, the sales amount priority sales policy considering only the sales amount is input to the web server, Like, the possible bid price (i>
6), the final stage (i =
16) The amount of money of 600,000 yen is the final successful bid price,
34 pieces are determined as the successful bid quantity.

If the seller has input the mixed sales policy condition in which the weight (a) given to the profit priority item is 0.93, as described above, the opportunity loss cost (OPi) Is the maximum return (max (yi)) * weight (a), 22,000,200 * (1-0.
93) Among the stages included within 1,540,014 yen, the stage having the maximum accumulated bidding quantity, i = 15, is awarded, so that the final successful bid price is 626,676 yen.
The successful bid quantity is determined to be 33.

FIG. 14 shows a second embodiment of the present invention.
A table corresponding to the case where the service operator is an intermediary distributor, after receiving bid request information for the same product from one or more sellers and determining the seller who presented the highest staircase price among them as the bidder After calculating the bidding price (UPi) for each stair sales volume (i) through the steps shown in FIG. 13, the bidding status and the accumulated bidding quantity (qi) for each step are stored.
The order unit price (oi) is the price to be paid when an order is received from the seller for only the cumulative bidding quantity (qi) at each stage. For example, at the i = 6 level, the total cumulative bidding quantity is 4, so 4 It is 920,002 yen, which is the amount when the unit price to be paid when ordering the individual is i = 4. Therefore, if the cumulative bidding quantity exceeds 16 and i = 9 or more, the same order price is determined to be 600,000 yen.
The total sales amount is calculated as bidable price (UPi) * cumulative bidding volume (qi) at each stage, and commission income received from the seller to the intermediary distributor as the service operator of the present invention is total sales amount * commission rate ( r). Of course, there may be no commission income received from the seller, and in this case, only transaction income, which is a distribution margin described later, is income.

The transaction profit of the distributor is the profit obtained when only the cumulative bidding quantity (qi) is sold at the bidding price (UPi) by receiving the goods at the order unit price (oi) for each stage,
Calculated by (UPi-oi) * qi. The total profit (yi) for each stage of the intermediary distributor is determined by the sum of the commission profit and the transaction profit. In this embodiment, the total profit of 4,000,200 yen at the stage i = 11 is the maximum profit (max).
(Yi)). Further, the opportunity loss cost (OPi) at each stage is calculated in the same manner as in FIG.

Similarly to FIG. 13, when the profit-priority sales policy condition (the weight value (a) of the profit-priority item is 1) is input, 733,400 yen at stage i = 11 is determined as the final successful bid stage. If it is determined and the sales volume priority sales policy condition (the weight value (a) of the profit priority item is 0) is input, 600,000 yen at stage i = 16 is determined as the final successful bid stage, and the profit is determined. If the weight given to the priority item is given as 0.4, the opportunity loss cost is 4,220,202.
Of the stages within * (1-0.4) = 2,532,121 yen, the lowest stage, i = 14, is selected as the final successful bid stage.

When the final successful bid conditions are determined in this manner, the consumer who has offered the bid price closest to the successful bid price is selected as the incentive providing winner, and the predetermined incentive is determined, as in the first embodiment. Provide. Incentives can be provided by cash payments, cyber money, product price discounts, etc.
It is not limited to these.

Further, as in the first embodiment, it is possible to recruit additional purchasers.
