Description

Reverse auction with two-way call {Method for reverse auction which buyer and seller both can offer a bid price}

The present invention relates to a reverse auction method through the Internet. More specifically, when a purchaser inputs a purchase type, a price, a purchase condition, a change in price, and a change in price through the Internet, the auction server automatically performs the search according to this condition. It is a reverse auction method that enables two-way bidding to gradually increase the price of purchase and find the sale candidate, and to make the price decrease through the reservation of the desired sale price of the seller.

In general, goods are traded using virtual spaces such as the Internet. Particularly, through auctions and reverse auctions, buyers can buy goods at lower prices, and sellers can sell goods at higher prices. To make it work.

Auctions are divided into British auctions and Dutch Auctions, depending on the type of item sold. Generally, auctions are widely used, starting from the lowest price of the item and gradually increasing the price. It is a way to determine the buyer as the buyer.

Dutch Auction starts with the highest price and gradually lowers the price. It is the way that the buyer who decides to purchase is determined as a buyer without setting a deadline.

Alternatively, there is a reverse auction method that exists only online, and when a purchaser of a membership or an article presents a purchase condition, the supplier who selects the lowest price by the deadline is determined as the supplier.

Here, the bidder of the British auction and the Dutch jade ship is the buyer, and the bidder of the reverse auction is the seller.

In a bid-to-price approach, the British auction fluctuates from a low to a high price, while the reverse auction and Dutch auctions start from a high price and fluctuate from a low price.

The auction end time is the British auction, the reverse auction is the auction end time pre-set by the auction client, while the Dutch auction is not determined according to the end time, the buyer's intention to buy means the end of the auction.

If the target of the auction is a commodity, the scope of comparison of the commodity is expanded so that it can be traded at a higher price to the person who needs it. Ensure that services are provided at a lower price.

For counterparties, they should be on equal positions. That is, in the case of British auctions and reverse auctions, the transaction will not be fair if the purchase or sale client presents an exorbitant minimum bid price.

Here, the minimum bid is a price not to be sold when the auction is closed at a price less than the price suggested by the seller at the time of auction request, which is the seller's authority. In addition, since the determination of the minimum bid is not disclosed to the counterparties, the efforts of all the bidders will be in vain if the price of the buyer who bids by the deadline falls below the minimum bid.

If the minimum bid is disclosed, there is no characteristic of the auction and it becomes a general commerce method.

In the case of Dutch jade, it does not require much effort from purchasers to purchase goods.

You just have to express your intention to buy. Even if the seller requested to sell, the auction is getting lower, so if there is no reason to proceed with the auction because there is no desire to purchase the auction, you can cancel the auction.

However, in the case of Dutch auction, time constraints follow. In other words, because the deadline is not fixed, you cannot enter the auction if you miss the time, and it is not developed into a transaction form where the buyer registers and purchases the product to be purchased. The limitations and one-sidedness of trading subjects have the problem of blocking the rapid development of e-commerce and limiting the opportunity to expand the user base.

The present invention is to solve the above-mentioned problems of the prior art, the purpose of the purchaser through the Internet to enter the type and price of the goods purchased, purchase conditions, price fluctuations, price fluctuations when the auction server to this condition As a result, it automatically raises the desired price of the purchase and finds the desired sales person, and the purchaser's reservation register also provides a reverse-auction method that enables the demand-oriented two-way call auction to lower the price through the competitive desired selling price reservation. .

The seller terminal 111 is used to log in through the web server 210. In the case of a registered user, when authentication is requested to the authentication unit 222 through the database interworking unit 220, the user database 231 checks the ID and password for the corresponding user and then authenticates the authentication result to the database interworking unit 220. Send to the web server 210 through.

If the user is not a registered user, the user information is input through the registration unit 221 to complete the user registration in the user database 231, and is authenticated to log in.

After completing the login, the purchaser terminal 111 registers an auction for the corresponding item through the reception unit 223. At this time, a purchase limit price is set and registered according to a purchase condition, a price fluctuation range and a price fluctuation period, or a necessity, such as a desired purchase price and quantity for reception.

The seller wishes to sell the goods through the predetermined seller terminal 121, accesses the web server 210 of the auction server 200 through the Internet, checks the purchased goods list and the goods information, and checks the purchased goods list. If there is an item you want to sell, it will indicate your intention to sell

To this end, the seller is authenticated through the authentication unit 222, and if not a registered user, the seller logs in after registering in the user database 231 through the registration unit 221.

The logged-in seller registers sales through the corresponding seller terminal 211, which registers sales information such as a selling price and a quantity in the auction information database 232 through the receiving unit 223.

Meanwhile, the auction information database 232 is updated by determining whether the auction is successful by comparing the desired selling price with the desired purchase price of the buyer with respect to the auction item registered in the auction information database 232, and updating the database linking unit 220. It transmits to the web server 210 through.

When the price change unit 225 reaches a desired purchase price change time set through the purchaser terminal 111, the price change unit automatically raises the desired purchase price width and registers it in the auction information database 232 as well as the database linkage unit ((220). ) Is transmitted to the web server 210. The web server 210 provides the updated desired purchase price to the buyer or seller terminal on the Internet.

The auction canceling unit 226 cancels the auction when the buyer cancels the auction for the auction items registered in the auction information database 232 and registers the cancellation in the auction information database 232 and announces and auctions them through a web server. It will be deleted from the list.

3 is a flowchart of a reverse auction process capable of a two-way call according to an embodiment of the present invention, and provides purchase or sale information to a terminal connected to the auction server 200 through the Internet. (S102)

If the connected terminal is a predetermined purchaser terminal 111, the auction information is inquired and the purchase is registered. (S104 to S112)

At this time, if necessary, the purchaser authenticates whether the purchaser is a user authenticated as a member through the user database 231, and enables purchase registration.

In the purchase registration, the purchaser terminal 111 sets the information and quantity of the desired purchase item, the desired purchase price, the desired price change time, and the desired price change width through the reception unit 223. (S114)

If necessary, the purchaser sets an upper limit of the item to be purchased so that when the desired price is automatically changed, if the upper limit exceeds the upper limit, it is automatically canceled. (S116) (S118).

As such, when the buyer inputs all the information for purchase, the reception unit 223 assigns an auction number and registers the database in the auction information database 232 (S122).

The auction information registered in the auction information database 232 is auction notice in real time on the home page through the web server 210 (S124).

If the price change time set by the purchaser is reached in the absence of a sales hopeless person, the price change unit 225 may be used to adjust the price up to the first set price change range (S130 to S134).

If the purchase price of the automatic raise is higher than the auction upper limit set by the buyer, the auction is automatically canceled and the auction is registered in the auction information database 232 (S140).

On the other hand, it is possible to cancel the auction by the buyer, if the auction cancellation request is received from the buyer terminal 111 by the auction cancellation unit 226 to proceed with the auction cancellation registration for the auction item in the auction information database 232 (S138)

If the seller wishes to connect using the predetermined seller terminal 121 (S130) (S142), if the auction information is inquired, the corresponding purchase item list is provided in real time through the web server 210 (S144).

After checking the purchase goods list displayed on the seller terminal 121, when the bidding or reservation registration proceeds for a predetermined item, the corresponding bidding result and reservation information are registered in the auction information database 232 (S146) ( S148) (S160) (S162)

When the sales bid data is received for the corresponding item in the seller terminal 121, after receiving the bid through the reception unit 223 and transmits the bid result to the buyer and the seller (S150).

If the successful bid is received by the buyer who has received the bidding result, the successful bidding result is stored in the auction information database 232, and then the bidding result is transmitted to the buyer and the seller (S156).

If the reservation registration is received by the seller terminal 121, the reservation registration information such as the sale reservation price and quantity is registered in the auction information database 232 and then the reservation registration result is transmitted to the buyer and the seller. (S164)

If the buyer selects an immediate purchase by satisfying the conditions such as the selling price of the seller who has pre-registered, the successful bid is made through the above-described auction process (S152 to S156).

On the other hand, the processing verification unit 224 compares the desired purchase price and the reservation registration price registered by the seller, if the desired sale price registered for purchase is higher than the desired purchase price to proceed with the successful bidding process (S152 ~ 156) do.

If the desired sale price registered in advance is lower than the desired purchase price, wait until the purchase price is automatically raised. That is, when the desired purchase price, which is increased according to the price fluctuation period and the price fluctuation set by the user, is equal to the desired sale price registered in the reservation, the successful bidding process (S152 to S156) is performed.

In addition, when a seller who has registered a sales reservation wants to change information such as a desired sale price, which he / she reserves, he / she checks the reservation registration status registered in the auction information database 232 through the reception unit 223 (S170) ( S172)

The seller who has received the reservation registration status data through the reception unit 223 enables the user to re-register by modifying the price registered in the reservation as necessary (S174).

As described above, since the seller can change the reservation registration information at any time, it is possible to implement a reverse auction capable of a two-way call that can be quoted by not only the buyer but also the seller.

Although a preferred embodiment according to the present invention has been described above, it is possible to modify it in various forms such as a purchasing agent for a joint purchase according to the shape of the buyer, if the person skilled in the art It is understood that various modifications and variations can be made without departing from the scope of the claims.

As described above, in the reverse auction method capable of two-way calls according to the present invention, when the purchaser inputs a purchase type, price, purchase condition, price fluctuation range, and price fluctuation period through the Internet, the auction server automatically performs the condition. It is possible to find a sales candidate by gradually increasing the purchase price.

In addition, by lowering the price through the reservation of the desired sales price competitive sellers, buyers can effectively purchase the desired goods at a lower price, and sellers can sell to buyers at their desired price It works.
