Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for conducting a transaction on a telecommunication line, and more particularly, to a bidding system for providing and intermediating a transaction place to a purchaser and a seller of various commodities, and a bidding system therefor. The present invention relates to a bid control method and a recording medium on which a bid management program is recorded.

[0002]

2. Description of the Related Art As a system for trading various commodities on a telecommunication line, there is a bidding (auction) system which provides a place of transaction between a merchandise selling side and a purchasing side and mediates.

[0003] In such a bidding system, a server device that manages bids is connected to a terminal device of each user such as a purchaser or a seller through a communication line to operate the device. You are bidding on the network. Conventionally, the seller registers goods and services to be sold to the consumer, and the bidding system publishes them on a communication line using an Internet web page or the like, and in response, purchases the goods or the like. The side wishing was to bid. In addition, the successful bid of the product is determined by determining the bidder who has bid the highest bid price as the successful bidder, and this successful bid is determined at the end of the bidding period.

In a bidding system, a server device automatically performs a series of processes from the start of a bid to a successful bid, such as a process of registering a product to be bid, a bid process, and determining a successful bidder, in response to an operation from each user. Can be processed. In addition, since such automatic processing can be performed, an extremely large number of bids can be registered, and the bids can be processed simultaneously in parallel.

[0005] Recently, there is also a "reverse auction" (reverse auction) system in which a bid is made in a direction opposite to the above-mentioned ordinary bid system.

[0006] In reverse auction, a purchaser of a product registers a product to be purchased in a bidding system, and the seller bids on the registered product, so that the lowest selling price to be a successful bidder is obtained. The purchaser purchases the product from the seller who bid for.

[0007]

As described above, the conventional bidding system has the following problems.

In the conventional bidding system, only the bid price can be designated at the time of bidding, and the system determines the successful bidder only based on the bid price.

[0037]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a block diagram showing a configuration of a bidding system 100 according to the first embodiment of the present invention.

Referring to FIG. 1, a bidding system 100 according to the present embodiment includes a bid management server 10 for managing bids for commodities, terminals 20 and 30 of a purchaser or seller of commodities, and a bid management server 10. Communicates with the terminals 20 and 30 via the communication line 40.

FIG. 2 shows a bidding system 10 according to the present embodiment.
It is a figure for explaining a bid using 0.

As shown in FIG. 2, the bidding system 100 according to the present embodiment is configured such that a seller 3 who sells a product for a product registered by a purchase candidate 2 who is a person who wants to purchase the product is registered. The seller 3 who has made a bid and bid on the cheapest selling price or the best selling conditions makes a successful bid, and the buyer 3 purchases the product from the winning seller 3.

The bidding system 100 of the present embodiment is for conducting an open bidding, and the purchasers 2 and sellers 3 who are users are irrespective of whether they are individuals, companies or organizations, respectively. The user can connect to the bidding server 10 via the communication line 40 and freely participate in bidding. The seller 3 only needs to be able to sell the bid product and provide the service, and the purchase applicant 2 only needs to be able to pay the price or the like as the price.

FIG. 3 is a flowchart for explaining the bidding process of the bidding system 100 according to the present embodiment.

Referring to FIG. 3, first, the purchaser 2
The merchandise desired to be purchased (or the service desired to be provided) is registered in the bidding server 10 by designating the price thereof (step 301). Upon receiving this registration, the bid server 10 publishes the data of the registered product on the communication line 40 such as the Internet (Step 302). As a result, for the product that the purchaser 2 wishes to purchase,
A bid from the seller 3 can be received.

The seller 3 makes a bid for a product that has been disclosed as a bid object, transmits the product to the bidding server 10 by designating the price of the product and the like (step 30).
4). The bidding server 10 similarly publishes a list of bidding data (amount and the like) by each seller 3 via the communication line 40.

Then, for reasons such as the end of the bidding period,
When the bidding has been completed (step 303), the successful bidder is determined (step 306), and the purchaser 2 of the product purchases the product from the seller 3 who is the successful bidder and conducts a transaction (step 307). Is completed.

Further, the bidding system 100 of the present embodiment
In bidding, instead of bidding only at the selling price, various other selling conditions (support, delivery date, quantity of goods, unit price, degree of scratches and dirt, warranty period, etc.) and these multiple conditions Can be performed by designating the sales conditions indicated by using a combination of

In this case, at the time of bidding in step 304, the seller bids by presenting not only the amount to be sold but also the sales conditions indicated by these various other sales conditions. 10 registers the bidding sales conditions and publishes a list of sales conditions of each seller on the communication line 40.

In the display of this list (in addition to simply displaying the list in the order of the bidding time), the sales conditions of the latest (ie, currently valid) bids of each seller are arranged in a form arranged for each seller. Display is also performed. Each seller who has made a bid can update the sales conditions displayed in this list to a new one by their own bid. This ensures that old listings of the same seller do not remain in this list for each seller (instead of being displayed in bid order).

In the determination of the successful bidder in step 306, not only the seller who bid for the lowest selling price is automatically determined as the successful bidder, but also the seller who wishes to purchase the product receives the sales presented by each seller. With reference to the conditions, a seller who presents the best conditions among the sellers is freely selected to determine a successful bidder.

Further, the side of the purchase applicant 2 also determines in step 30
At the time of registration of one product, the purchase condition indicated by using these various conditions (price, support, delivery date, quantity of the product, unit price, degree of scratches and dirt, warranty period, etc.) for the product desired to be purchased can be specified. . The bidding server 10 discloses the registered purchase conditions on the communication line 40, and each seller 3 can receive a bid satisfying the purchase conditions by referring to the purchase conditions.

FIG. 4 is a view showing an example of a screen for displaying information on a bid according to the present embodiment. In the example of FIG.
The bidding information shown in the form of a web page is displayed using a web browser provided in the user's terminal.

In this example, a back number of a certain monthly magazine for one year last year is registered as a product desired to be purchased, and a bid for this monthly magazine is made.

For this product, "A secondhand bookstore"
Three sellers, "Books B" and an individual "Mr. C", are bidding. The purchase applicant compares the conditions presented by the sellers and freely selects the successful bidder.

Although the bid amount of "Books B" is considerably higher than that of other bidders, a purchaser can designate "Books B" as a successful bidder especially if he / she wants to obtain a new one.

The bid amount of “Mr. C” is the same as the “A secondhand bookstore”. "Mr. C" has a comment stating that if a successful bid is made, the back number of this year will be given free of charge, so if the purchaser wants to obtain this as well, the conditions are more favorable than "A old head office" It is. However, in the case where this is unnecessary, such as when the purchaser has already obtained this year's portion, the condition presented in the bid is the same as that of "A secondhand bookstore".

In the case where it is known whether the seller is a trader or an individual as in the example of the drawing, this can also be used as a judgment target for selecting the successful bidder.

As described above, the purchaser selects the successful bidder by comparing the sales conditions and the like presented by the bidder. Also,
Bidders bid on and update their bidding records, submitting sales terms and conditions in favor of other bidders.

Processing such as bidding is performed on a page linked from the screen of this HP or on this HP.

Next, the bidding system 100 of the present embodiment

It is not necessary to use different devices, and the same terminal device may be used for both the bidding by the seller and the presentation of the product desired by the buyer.

The communication line 40 is a communication line for transmitting and receiving data such as commands for various operations in bids and amounts.
For example, an Internet line, a telephone line, a wireless telephone line, and various other information communication lines can be used.

Referring to FIG. 1, the bidding server 10 includes a communication unit 11 for communicating with the purchase terminal 20 and the sales terminal 30 via a communication line 40, and a product registration unit 12 for receiving registration of a product from a purchaser. A bid receiving unit 13 for receiving a bid from a seller, a product information storage unit 14 for recording information about the bid, a display control unit 14 for controlling display of information about the bid to be disclosed on the communication line 40, and use. An authentication unit 16 for confirming the identity of the person is provided.

The communication unit 11 notifies the purchase terminal 20 or the sales terminal 30 which is the user's terminal of the product to be bid and the status of the bid via the communication line 40, Is received, and a bid operation for the registered product is accepted.

The communication unit 11 can be realized by, for example, having a function of a web server of the Internet. In this case, by displaying the above-mentioned information on the bid on the web page, the information of the bid can be provided to each user, and various operations from each user can be performed by CGI or various scripts. Alternatively, it can be accepted using an e-mail or the like.

The merchandise registration section 12 and the bid accepting section 13 receive the operation of merchandise registration and bidding from the user terminal received by the communication section 11 and register them in the merchandise information storage section 14.
A web page or the like for displaying new information is generated or updated, and this information is made public on the communication line 40.

The method of receiving an operation from the user is, for example, in the case of performing communication via the Internet, in order to input necessary information such as a description of a product to be registered and an amount to be bid, and transmit the information to the bidding server 10. By displaying the form.

This form displays an object such as a text area for inputting characters and a submit button for transmitting data to the server side in a web page by using an HTML sentence tag or various scripts. realizable.

In the product registration form, data such as the type, name and description of the product, the bidding period and the upper limit of the bid price are entered, and in the bid form, the product price and the description of the product to be sold are entered. And so on. An object for inputting (or selecting or specifying) other necessary information is displayed on the form.

When the user inputs necessary information in the form and transmits it to the bidding server 10, the merchandise registration unit 12 and the bidding reception unit 13 register the information and update the display of a web page or the like, thereby registering the merchandise. And bid operation is accepted.

The information on the bidding recorded and registered by the merchandise information storage unit 14 is, for example, information on a bidding target product.

Further, image data or the like of a product exhibited by each bidder may be recorded.

As the product information storage unit 14, a recording device such as a hard disk or a semiconductor memory can be used.

The display control unit 15 extracts the information to be disclosed to the user from the information on the above-mentioned bids from the product information storage unit 14, edits the information into an appropriate display form set in advance, and communicates from the communication unit 11. This is disclosed to each user via the line 40.

For example, when publishing information by using a web page on the Internet, the above-mentioned information on a bid is converted into an HTML sentence or the like to create a web page, and the user performs an operation (purchase request). When a new bid target product is registered by a seller or a bid operation is performed by a seller, the related web page data is updated to the latest one.

The authentication unit 16 confirms the identity of the user by using a password or the like. By verifying the identity, the purchaser who registered the product or the seller who made the bid is proved to be a properly registered purchaser or seller, thereby increasing the credibility of the bid transaction. be able to.

For example, the registration of the product shown in FIG. 3 (step 30)

Only in such a case, it can be performed by a method such as accepting an operation from the user.

With the bidding system 100 of the present embodiment described above, an open bid for a purchaser of a product to select a seller to purchase the product is provided to the purchaser or the seller. be able to. In addition, since a bid can be made by designating not only the price to be sold but also various other sales conditions, a more flexible and detailed bidding service can be realized.

Next, a second embodiment of the present invention will be described.

In the above-described first embodiment, various conditions such as the number of products, unit price, and delivery date other than the amount of money can be specified in the bidding. However, in the example of FIG. Are registered and displayed as comments or product descriptions.

In the present embodiment, the types of items to be individually displayed in this list are set in accordance with the operation by the purchaser or the seller.

For example, in response to the user's instruction, the display control unit 15 newly displays a column for displaying the data of each designated condition in the list and displays the column.
And the bid receiving unit 13 can individually input these designated types of conditions in a form for performing a bid or the like.
Processing such as adding an object such as a text area for inputting data is performed.

FIG. 5 is a view showing an example of a screen for displaying information about a bid according to the second embodiment of the present invention. In the example of FIG. 5, similarly to the example of FIG. 4, the information of the bid shown in the form of the web page is displayed using the web browser provided in the user terminal.

In this example, a ticket for a certain concert is registered as a product desired to be purchased, a bid is issued for this monthly magazine, and a large number of tickets are desired to be purchased.

For this product, "D"
Three sellers, "Mr. E" and "Mr. F" are bidding. The purchase applicant compares the conditions presented by the sellers and freely selects the successful bidder. Also, since the purchaser in this example wants to purchase a large number of copies,
More than one bidder may be selected as the winning bidder.
