Description

Bidirectional Auction Method and Apparatus Using Computer Network {METHOD AND APPARATUS FOR BIDIRECTIONALLY AUCTIONING BETWEEN BUYERS AND SELLERS USING COMPUTER NETWORK}

The present invention relates to a method and apparatus for interactive auction using a computer communication network, and in particular, a small number of sellers can freely participate in a plurality of sellers, a plurality of sellers, and a lower seller with reference to a cumulative sales quantity, The present invention relates to a method and apparatus for interactive auction using a computer communication network capable of selecting a cumulative sales quantity and allowing a completely free market transaction by a bilateral competition.

Recently, various electronic commerce using the Internet has been introduced. There are three types of e-commerce: shopping mall, auction, reverse auction, and matchmaking.

Most e-commerce uses a shopping mall method. The shopping mall method is a method in which a seller opens a virtual store on the Internet and displays a product to be sold in the opened virtual store, where the buyer visits the virtual store and orders the product. Since the shopping mall method is mainly a seller, a buyer purchases a product based on a seller's suggested selling price, the buyer visits the cheapest mall by purchasing a price for the same product of a plurality of shopping malls and purchases the product. Therefore, there is a hassle and inconvenience that the buyer has to remember the shopping mall with the lowest price for each product by doing a price research. In addition, since the payment method, order method, delivery period, shipping fee, etc. are different for each shopping mall, all of these conditions must be arranged by the buyer to make a sensible purchase.

In the auction method, when a seller attaches a product to an auction, a plurality of buyers present various purchase prices and determine the buyer who presented the most expensive purchase price as the final purchaser as the final purchaser and close the transaction. That is, since the auction method is a method of determining the highest price by competing a plurality of buyers, the buyers are required to obtain the auction information and to participate in the auction by finding the auction place and auction time of the related product.

The reverse auction method, as disclosed in US Pat. No. 5,794,207, is that when a buyer presents a purchase condition, a plurality of sellers refer to the proposed purchase condition to determine the first approved seller among the acceptable sellers so that a transaction can be made between the buyer and the seller. . This reverse auction method is convenient for the buyer because it is a buyer-centered transaction because many sellers compete for one purchase condition. However, the seller can not expect a large amount of commodity trading because the deal is made with one buyer in every transaction.

As for the matchmaking method, as disclosed in Korean Patent Laid-Open Publication No. 1999-78767, when a buyer and a seller register both a product, a purchase price, and a product and a sale price together, the middleman concludes the lowest desired selling price from the desired purchase price among the quantity sold less than the purchase quantity. It is determined by the price so that the buyer and seller deal can be made. As a matchmaking method, the buyer and seller are registered at the same time to find the lowest desired selling price from the desired purchase price, and the buyer and seller are connected. Can not. In addition, the buyer could not purchase the quantity of sales of many small quantity sellers at the same time for the same product.

In addition, synergy auctions on the auction site (www.auction.co.kr) operated on the Internet is a kind of joint purchase method for displaying a product / sales quantity / purchase quantity / current price for a predetermined time, and the corresponding product according to the purchase registration. In response to an increase in the number of purchases, the auction method introduces a discounted amount. In this method, the quantity of the sale items is limited in advance, the purchaser cannot present the purchase price, the price is reduced by a certain rate by the registration of the corresponding product of the buyer, and the discountable amount is limited.

However, the conventional electronic commerce method described above has a problem in that a seller or a buyer cannot make a deal of mass purchase at the same time because it is a one-to-one or one-to-many method. That is, since sellers cannot offer various selling prices for the same kind of products, and each sale or purchase is managed for each case, there is a problem that a large quantity of buyers cannot purchase products of a plurality of small sellers at once.

The purpose of the present invention is to solve the problems of the prior art, a large amount of commerce by the competition between a large number and a large number of free market competition between the seller and the buyer is possible for a small amount of sellers easy sales strategy and the buyer can buy a computer communication network It is to provide an interactive auction method and apparatus used.

It is another object of the present invention to present a plurality of small quantity sellers of the same kind of products as lower cumulative sales quantity, so that many buyers can competitively select a variety of purchase quantity interactive interactive auction using a computer communication network that can facilitate commerce A method and apparatus are provided.

It is still another object of the present invention to provide an interactive auction method and apparatus using a computer communication network that can activate mass commerce through the Internet.

In order to achieve the above object of the present invention, the method of the present invention simultaneously displays in real time at least one or more sales prices and the cumulative sales quantity below each sale price for the same product, and the at least one seller displays Competitively participate in the desired selling price by referring to the cumulative sales quantity, and at least one purchaser competes to select an acceptable selling price based on each sales price and subordinate displayed by referring to the cumulative sales quantity and selects an appropriate purchase point in the gross concept. First, the selected buyer and the selected sale are characterized by confirming the transaction between all the sellers below.

In addition, the method of the present invention is a two-way auction method using a computer communication network which establishes a transaction by bilateral contention between at least one or more sellers and at least one or more buyers, wherein at least one or more sellers are provided with a product / model, Inputting a selling price, a selling quantity, a selling down payment, and in the computer, for each entered product / model, at least one selling price, selling quantity for each selling price, and own selling value for each selling price. Displaying a cumulative purchase quantity by a sub-sum of sales quantities less than or equal to the selling price; and at least one or more buyers, at least one selling price and cumulative selling quantity and cumulative selling quantity of each product / model displayed on the computer; Competitively selecting the quantity sold, and from the computer, the furthest from the selection step Our buyers selected in the step of determining the purchase of rights to the cumulative sales volume or more selected computer, characterized in that it comprises a step for confirming the transaction between the buyer and the determined selected sales all over the seller.

There may be cases where the lower price is available to the purchaser for all of the cumulative sales quantity and for some quantity. The former is advantageous to the buyer who wants to secure a large quantity of purchases. In the latter case, a buyer who wants to purchase a lower quantity than the cumulative sales quantity can purchase at a lower price and can accommodate various purchase quantities.

In the case of some purchases, some sellers are determined by the sales registration number ranking corresponding to the quantity that can be purchased by the buyer.

In the inputting step, it is preferable to further display the selling period information, the selling price, and the total amount of the multiplied multiplying sales quantity among the seller input information. In addition, it is more preferable to further display analysis information in which the lower level analyzes the change in cumulative sales quantity in order to assist the purchasing strategy. In addition, various analysis graphs, for example, sales volume and cumulative sales volume graphs for each selling price, graphs of changes in the confirmed sales price for the purchase confirmation date and time, and graphs of the confirmed cumulative sales quantity (transaction volume) for the purchase confirmation date and time It is preferable to provide such as. This analysis graph helps the seller to register the selling price and to determine the purchase point and the selling price of the seller.

In the display step, it is preferable to display the selling price in order from high to low.

In the step of determining the purchasing right, after selecting the acceptable selling price and the cumulative selling quantity, the purchasing right is determined in the order of depositing the purchase down payment first to induce competition.

The apparatus of the present invention executes the storage means in which the interactive auction program is stored, and the interactive auction program stored in the storage means, to input a product / model, a selling price, a sales quantity, a sales down payment input by at least one or more sellers, The cumulative sales quantity is displayed by adding the at least one selling price, the selling quantity for each selling price, and the selling quantity below the selling price for each selling price, for each inputted product / model. At least one buyer inputs at least one selling price and a lower selling price of each displayed goods / model, and inputs selection data that competitively selects the selling price and the lower selling cumulative selling quantity that are acceptable to the selected selling quantity, If the first buyer selected in the step has a child above the selected sale price, And a processor for determining a purchasing right and for confirming a transaction between all the sellers whose determined buyer and selected selling price are below.

The storage means includes a member database, a sales registration database, a sales registration display database, a purchase application database, a purchase confirmation database, and a registered product database.

Hereinafter, with reference to the accompanying drawings, it will be described in detail the present invention through an embodiment of the present invention.

Figure 1 shows the configuration of the interactive auction method of the present invention. As shown in FIG. 1, in the two-way auction method of the present invention, the seller 10 and the buyer 20 make a transaction through the two-way auction system 30, and the payment is paid from the buyer to the seller through the two-way auction system. In this case, the seller 10 delivers the purchased goods to the buyer 20.

In particular, the present invention is different from the general auction or reverse auction, as shown in the following <Table 1>, it is possible to register a variety of selling price for one product, by displaying the cumulative sales quantity at the same time for each sale price, The buyer can choose the selling price competitively according to the seller's own decision considering the total purchase amount by multiplying the cumulative selling quantity and selling price.

Table 1 shows the principle of interactive auctions for a particular product

Sales price (KRW) Quantity sold Child Cumulative Quantity () Total purchase amount (KRW) Purchase down payment (KRW) General selling price 50,000 5 625 31,250,000 3,125,000 48,000 35 620 29,760,000 2,976,000 45,000 165 585 26,325,000 2,632,500 40,000 200 420 16,800,000 1,680,000 35,000 150 220 7,700,000 770,000 cost 30,000 50 70 2,100,000 210,000 28,000 20 20 560,000 56,000

In other words, it is expected that a small amount of sellers can sell a small amount of goods at a reasonable price by inducing the sellers to register their sales competitively at a selling price with a high possibility of selecting buyers based on the cumulative sales quantity, thereby allowing a large deal to be concluded at a reasonable price. Draw up a hearing. In addition, the buyer can secure a desired quantity in large quantities by making a competitive selection at a purchase down payment, eg 10%, which is part of the purchase price.

For example, it is useful for commerce between small producers, such as agricultural products and seafood, and wholesalers who buy large quantities of these products and hand them over to retailers. It is also useful for commerce between small sellers who own small amounts of unlisted securities or over-the-counter securities, bonds, etc., and government or institutional buyers to buy large quantities from them.

In Table 1, if a small amount of sellers openly open a sales intention on the interactive auction site (www.biaution.com) for a product with a cost of 30,000 won and a general sale of 50,000 won, the buyer will be able to buy the interactive auction site. For example, if you decide on a purchasing strategy based on the concept of total purchases at www.biaution.com and subordinates multiplying the cumulative sales volume, you will select a sale price of 40,000 won, for example.

If the purchase is confirmed, the subordinates of 20,000 won to 35,000 won are also collectively purchased at the confirmed sale price, for example, 40,000 won for the sales quantity. Therefore, the sellers registered at the lower selling price are sold at a selling price of 40,000 won, which is higher than the selling price registered by them.

This type of transaction can be expected to increase the profits of small sellers, especially farmers and smallholder securities traders. Thus, more small amount of sellers leads to competitive sales registration.

In addition, when the purchase is confirmed, it is also possible for the purchaser to purchase at a selling price registered by the seller with respect to the lower quantity sold. This approach is advantageous to the buyer over the approach described above.

Sellers with capital margin will register at selling prices of more than 45,000 won for high returns, and sellers who are in urgent need of capital due to lack of capital will register at lower selling prices of less than 40,000 in anticipation of prompt sales.

That is, a large number of buyers can apply for a competitive purchase in accordance with a purchasing strategy that is advantageous to them in order to secure large quantities.

On the other hand, the seller sees the contents publicly and competitively participates in the sale price that is most likely to make a purchase decision at the highest value in the shortest time, so that the cumulative sales volume of the sale price that is more likely to make a purchase decision is higher than other selling prices. The increase rate is shown. This phenomenon is a natural free market competition principle, which leads the seller's selling price to the highest selling price.

2 shows the configuration of the interactive auction apparatus of the present invention.

The interactive auction apparatus includes a server 100 on which a processor for executing an interactive auction program is mounted and a storage means 110 in which a database is stored. The server 100 executes the interactive auction program while referring to or updating various databases stored in the storage means 110.

The database includes a purchasing member database (BMDB: BUYER MEMBER DATA BASE) (111), a sales member database (SMDB: SELLER MEMBER DATA BASE) (112), and a sales registration database (SRDB: SELLING REGISTRATION DATA BASE) (113). , SELLING REGISTRATION DISPLAY DATA BASE (SRDDB) (114), PURCHASE OFFER DATA BASE (PODB) (115), PURCHASE DECISION DATA BASE (PDDB) (116) REGDBED REGISTED GOODS DATA BASE (RGDB) 117 and the like.

The interactive auction apparatus includes terminals 130 and 140 connected to the server 100 through a computer communication network such as the Internet 120, such as a personal computer, a notebook computer, a hand computer, an Internet mobile phone, an Internet television, and the like. In the embodiment of the present invention, an example of a personal computer is shown.

The purchase application terminal 130 and the sale registration terminal 140 are equipped with a purchase application and sale registration program. The purchase application and sales registration program are downloaded from the server 100 via the Internet or installed on the hard disks of the terminals 130 and 140 from a recording medium such as a distributed compact disc (CD).

Referring to Figure 3, the purchase member database 111 is ID / password / name or company name / resident registration number or business registration number / postal code / address / contact / E-MAIL / new sales registration list / bonus points / purchase performance It includes fields such as list / bonus points / credit.

The address may include a home address or a recipient address. The contact information includes a phone number / cell phone / call number.

The new sales registration list includes a case in which the buyer registers a new product that is not registered on the server 100 or registers a new sale price that is not included in the ongoing sales price in the case of the already registered product. For example, if a sale price registered for a product A is 10,000 won and 9,000 won, a new sale price 9,500 won may be registered as a new sale price. Bonus points for new sales registration can be earned and replaced with electronic money.

In the purchase record list, the purchase price selected by the buyer and the lower purchase price, the contents of the purchase confirmation, the product, the quantity, and the total purchase amount related to the cumulative sales quantity are listed.

Purchasing member management is managed by credit rating automatically considering the number of new sales registration, bonus point accumulation and purchase results, return rate, seller complaints, and delivery accidents.

Referring to FIG. 4, the sales member database 112 includes ID / password / name or corporation (company) name / resident registration number or business registration number / zip code / address / contact number / E-MAIL / new sales registration list / bonus points. Includes: Ongoing Sales Registration List, Sales Performance List, Bonus Points, and Credit.

The progress sales registration list is a list of ongoing sales registrations in which the sales period is not completed and the purchase is not confirmed. Therefore, the seller can look at the ongoing sales registration status with reference to the progress sales registration list.

In addition, the sales performance list lists the overall sales registration status including the invalid sales registration status that participated but not purchased, the valid sales registration status where the purchase is confirmed and sold, and the total accumulated sales amount. Therefore, it is possible to confirm the sales closing rate according to the sales registration frequency of each seller. Therefore, the operator side of the server 100 may provide an electronic money or a bonus product by accumulating bonus points according to the sales results in consideration of the total number of registrations, sales hit ratio, cumulative sales total amount, and the like.

The credit rating is automatically used to manage the seller by giving the seller's credit rating automatically, reflecting the number of cancellations, returns, and sales after the seller's sales registration.

Referring to Figure 5, the sales registration database 113 is a sales registration number / product and model name / sales price / sales quantity / sales period / seller ID / sales contract amount / credit card number / card expiration date / name on the card / other Includes matters.

The sales registration number is automatically assigned by the system according to the sales registration order. The selling period is determined arbitrarily by the seller in consideration of the time required.

The sales contract amount is automatically calculated as part of the selling price, for example 10%. The sales contract amount will not be returned when the sales registration is canceled and will be returned to the settlement account of the credit card at the end of the sales period.

Upon confirmation of purchase, the payment will be automatically deposited to the credit card settlement account.

Referring to FIG. 6, the sales registration display database 114 is the day of the product registration number / product and model name / general selling price / brief description / selling price / sales quantity / subordinate cumulative sales quantity / total purchase amount / total cumulative sales quantity Includes% of period closing quantity and more.

The sales registration indication data is provided to the terminals 130 and 140 in real time so that the buyer and seller can see the sales registration status in real time.

The selling quantity is the total selling quantity registered at the selling price, and the lower selling cumulative selling quantity represents the selling quantity that accumulated the total selling quantity of the lower selling price below the selling price.

The distribution of sales registration for a commodity is widely distributed between the general selling price and zero, which is likely to close, and greatly decreases as the general selling price approaches. Will decrease. Therefore, the sales volume for each selling price as a whole is a bell-shaped curve.

However, as the selling price of the lower selling price accumulates toward the higher selling price, the cumulative selling quantity draws an S-shaped curve with the largest slope near the cost.

The total purchase amount is automatically calculated by multiplying the cumulative sales quantity by the selling price, and helps the buyer to decide whether to buy from this total purchase concept. In addition, after the same day, the amount of sales at the end of the sales period is displayed as a percentage of the total cumulative sales, thereby helping the purchaser to determine the purchase time.

Referring to Figure 7, the purchase application database 115, the purchase application number / product registration number / product and model name / sales price / subordinate cumulative sales quantity / total purchase amount / buyer ID / purchase contract amount / credit card number / card validity Include period / name on card.

The purchase application database 115 is composed of data inputted by the purchaser when purchasing a purchase through the terminal. The purchase contract amount is automatically calculated and processed as 10% of the total amount, and the purchase contract money is withdrawn from the payment account of the entered credit card number and deposited into the operator's account, and the right depositor is given a purchase right. The down payment will not be returned when the purchase is canceled, but will be distributed to the relevant sellers as compensation for the accident.

Referring to Figure 8, the purchase confirmation database includes a purchase confirmation number / product registration number / product and model name / selling price / child cumulative sales quantity / total purchase amount / buyer ID / related total seller IDs / other items.

The purchase confirmation database is automatically created by referring to the purchase request database and the sales registration database since the purchase price of the selected sales price and subordinate are all confirmed by the sellers related to the cumulative sales quantity. do.

9, the registered product database is a product registration number / product and model name / general selling price / brief description / detailed description / large category / middle classification / small category / cumulative sales quantity / manufacturer website link information (URL: UNIFORM RESOURCE LOCATORS) And the like.

A brief description of the registered product database includes a picture of the product, typical specifications, a brief product description, the manufacturer, and so on. The detailed description includes a detailed description of the product, a structure, various pictures, and the like, and the reliability and findings of the product surveyed by the interactive auction operator.

10 is a flowchart for explaining a server operation of the interactive auction apparatus according to the present invention.

When the server 100 checks a specific time, for example, 24 hours every day (1002), the server 100 deletes the sales registrations for which the sale period ends on the same day with reference to the SRDB 113, and displays the sales quantity of the sales registrations for which the sales period ends the next day. Investigate (1004). Regarding the deleted sales registration, the sales quantity / child of the SRDDB of each product updates the cumulative sales quantity / total purchase amount. The SRDDB is updated (1006) by calculating the percentage of the closing amount of the same-day sales period out of the total cumulative sales quantity of each product by referring to the sales quantity investigated in relation to the sales registration expired the next day (1006). It then registers with the associated BMDB and SMDB (1008).

If it is not the check time in step 1002, it is checked whether there is a member registration request from the terminals (130, 140) (1010).

If there is an application for membership in step 1010, it is checked whether it is a purchase membership or a sales membership (1012). If it is a purchase member subscription in step 1012, the purchase member data is input (1014) and the entered purchase member data is registered in the BMDB (1016). If the sales member is registered in step 1012, the sales member data is input (1018), and the input sales member data is registered in the SMDB (1020).

In step 1010, if the membership is not registered, it is checked whether there is a sales registration request from the terminals (130, 140) (1022).

If there is a sales registration in step 1022, it is checked whether it is a new registration (1024). If it is a new registration in step 1024, it is checked whether a new product is registered (1026). If the new product is registered in step 1026, enter the product and model name / sales price / sales quantity / sales period / seller ID / credit card number / card expiration date / name on the card (1028). The input product and the model are registered in the DGDB (1030).

In step 1026, if the new product is not registered, the selling price / selling quantity / selling period / seller ID / credit card number / card expiration date / name on the card is input (1032).

If it is not a new registration in step 1024, since the ongoing sale is a participant, input the sales quantity / sale period / seller ID / credit card number / card expiration date / name on the card (1034).

1010, 1032, or 1034 by requesting a sales deposit from the payment account of the credit card number entered in step 1036 to check whether the deposit is confirmed. If the payment is not made in step 1036, error processing is performed (1038). If the sales deposit is received in step 1036, the sales registration details entered in the SRDB are registered (1040), the relevant contents of the SRDDB are updated (1042), and the sales registration details are registered in the BMDB or SMDB of the associated ID (1044). ).

If it is not a sales registration request in step 1022, it is checked whether there is a purchase request (1046). If there is a purchase request from the terminals in step 1046, enter the buyer ID / credit card number / card expiration date / name on the card (1048). The input purchase application data is registered in the PODB (1050).

Subsequently, the payment request is made from the inputted credit card payment account of the purchase applicant and the payment is checked (1052). If the deposit is not made in step 1052, an error process is performed (1054). If the purchase down payment is received in step 1052, the first buyer is determined (1056).

Once the purchaser is decided, it registers in the PDDB by referring to SRDB and PODB, updates the confirmed sale registration in the SRDDB, deletes the sale registration in the SRDB, and confirms the purchase confirmation of the confirmed buyer and the confirmed seller. It registers with BMDB and SMDB (1058). Subsequently, the payment for the purchase price is processed by depositing the balance of the total purchase amount other than the down payment of the purchase price from the credit card settlement accounts of the purchaser (1060).

The purchaser confirms the purchaser's delivery information from the BMDB and provides the seller's delivery information to all confirmed sellers via e-mail, and simultaneously prepares and provides the buyer with a list of IDs of all sellers with reference to SMDB (1062).

If it is not a purchase request in step 1046, it is checked whether there is a data output request (1064), and if there is, it outputs related data with reference to the database (1066).

In step 1064, if there is no data output request, it is checked whether there is a delivery completion report (1068), and upon receipt of the delivery completion report, the seller pays the selling price and the down payment of the related sellers through the settlement account of the seller.

14 is a flowchart illustrating the operation of the terminal of the interactive auction apparatus according to the present invention, and FIGS. 15 to 24 show screen state diagrams.

Referring to the drawing, in the terminal 130, 140, when the interactive auction icon is clicked on the window start screen, the interactive auction program is executed. 1110 is connected to the interactive auction site (www.biauction.com) via the Internet by a telephone connection on a web browser. When accessing the interactive auction site in step 1102, the server 100 and the terminals 130 and 140 are interconnected through the Internet 120.

At the request of the terminal, the server 100 provides the interactive auction homepage of FIG. 15 and displays the homepage screen on the terminal (1104).

On the homepage screen of Fig. 15, there are home / membership / sales registration / purchase application / sales registration list / registered product list / purchase confirmation list, which are main menus, and a product search tool on the left side of the screen. The product search tool can search by product classification and search by inputting letters and numbers such as product name, product registration number, sales registration number, purchase confirmation number, and sales price. In the center of the screen, the name of the major category for the product search and the numerical information indicating the number of sales registrations of each major category are displayed. The illustrated large classification name is one embodiment, and various major classifications and their names may be selected in screen design.

When the member registration menu is clicked on the homepage screen (1106), the member registration screen shown in FIG. 16 is displayed (1108). When a purchase member is clicked on the member registration screen of FIG. 16, a purchase member input window as shown is displayed. When the sales member is clicked, a sales member input window similar to the purchase member input window is displayed. When the member information is input to the input window of FIG. 16 and the member registration button is clicked on the screen, the input member information is transmitted to the server 100 and registered in BMDB or SMDB of the database 110 (1110).

In step 1106, if it is not a member registration, it is checked whether there is a product search command (1112). The product search command is inputted by clicking a category of the major categories of products on the screen or by using a search tool on the left side of the screen. In FIG. 15, when " 1. Furniture / household goods " is clicked, the small and medium classification screen of FIG. 17 is displayed. When the "lighting apparatus" is selected on the small and medium classification screen of FIG. 17, the registered product list screen of FIG. 18 is displayed (1114).

When a desired product, for example, an “inverter stand” is clicked on the screen displayed in step 1114 (1116), a sales registration list screen of the inverter stand of FIG. 19 is displayed (1118).

In the screen of FIG. 19, when the seller or buyer clicks "view graph", the graphs of FIGS. 25 to 27 can be viewed. For example, a graph of sales quantity and cumulative sales quantity for each selling price of FIG. 25, a graph of variation of the firm selling price with respect to the purchase confirmation date and time of FIG. 26, and the confirmed cumulative purchase quantity with respect to the purchase confirmation date and time of FIG. 27 (transaction volume) ), You can see a graph of variation. The seller or the buyer refers to such an analysis graph to determine the desired selling price registration or selling price of the purchase application.

In the screen of FIG. 19, when a seller determines a selling price (1120), a selection window for selecting a purchase and a sale is displayed on the screen. If sales are selected from the displayed selection window, the sales registration screen of FIG. 20 is displayed (1126).
