Thus, business negotiations close to the real world are possible.
[0027]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 3 shows the configuration of the price determination system of the present invention.
[0028]
The system shown in FIG. 1 includes a plurality of terminals 10, a network 20, an interface 30, a price determination device 100, a product management database 40, a customer management database 50, and a sales policy description file 60.
[0029]
The merchandise management database 40 is a database for managing handled merchandise information. As shown in FIG. 4, information on merchandise such as merchandise code, merchandise name, inventory quantity, purchase price, list price, and next arrival date is accumulated. And can be accessed from the interface and the price determining apparatus 100.
[0030]
The customer management database 50 is a database for managing customer information of merchandise purchasers. As shown in FIG. 5, customer information such as customer ID, name, address, date of birth, purchase price, and other purchase history is accumulated. And can be accessed from the interface 30 or the price determination device 100.
[0031]
The sales policy description file 60 is a file describing a sales policy such as negotiation conditions and negotiation break conditions. The sales policy description file 60 includes a usage data table that is a list of data items of customer information and product information to be used, and negotiation results and negotiations. There are three tables: a negotiation table in which conditions for performing are written, and a negotiation breakdown table in which conditions for breaking up the negotiation are written. Further, at least one sales policy description file 60 exists in the present system, and when there are a plurality of sales policy description files 60, they are selected randomly. By selecting at random, the sales strategy can be prevented from being deciphered from the buyer's terminal.
[0032]
The interface 30 accesses the product management database 40, obtains various acquired product information, creates a screen (HTML file) for displaying the acquired information, product purchase buttons, negotiation input windows, etc. The browser of the terminal 10 of the client is updated via 20. In addition, the screen configuration is held in the client terminal 10 as an application, and only the product information is updated via the network 10. In addition, when the buyer inputs the product to be ordered and the negotiation for negotiation in the purchase on the terminal 10 based on the product information, processing such as passing the input to the price determination device 100 is performed.
[0033]
There are two main types of negotiations, one is to enter a specific amount (negotiation amount for negotiations), and the other is an action, such as “Price discount” or “Add bonus”. (Negotiation negotiations) This behavior may be prepared on the interface 30 side, displayed on the screen in advance, and selected by the buyer.
[0034]
The price determination device 100 is a device that determines the sales price of a product with reference to the product management database 40, the customer management database 50, and the sales policy description file 60.
[0035]
FIG. 6 shows the configuration of the price determination apparatus of the present invention.
[0036]
The sales determination device 100 shown in FIG. 1 includes a buyer information input unit 110, a price determination unit 120, and a notification unit 130.
[0037]
The buyer information input unit 110 inputs customer information (customer ID), order list, negotiation details, etc. of the buyer via the interface 30 and passes the information to the price determination unit 120.
[0038]
The price determination unit 120 searches the sales policy description file 60, the product management database 40, and the customer management database 50 based on information input by the buyer, and the price of the product ordered by the buyer according to the search result. To decide. For example, processing such as determining a new product price or proposing a product that can be added free of charge is performed based on the negotiation conditions, and the determined price is sent to the terminal 10 via the interface 30.
[0039]
In the following, an operation in the price determination device 100 for determining the price of a product while exchanging with the buyer's terminal 10 via the network 20 and the interface 30 will be described.
[0040]
FIG. 7 is a flowchart of the commodity price determination process of the present invention.
[0041]
As a premise of the processing shown below, when a buyer purchases a product, the desired product, the number of products, and negotiation negotiation are transmitted to the price determination device 100 together with the customer ID. At this time, the price determination device 100 If the customer does not exist due to the buyer making a first purchase or the like, a customer registration form or the like is output and passed to the buyer's terminal 10 to create customer information.
[0042]
Further, as shown in FIG. 8, the usage data table of the sales policy description file 60 used in the following shows the accumulated purchase amount for the items in the customer management database 50 to be referred to and the items in the product management database 40 to be referred to. , Inventory quantity, purchase value.
[0043]
Further, as shown in FIG. 9, the negotiation table of the sales policy description file 60 includes a negotiation result and conditions corresponding to the negotiation result.
[0044]
Furthermore, the negotiation breakdown table of the sales policy description file 60 describes conditions that serve as negotiation breakdown conditions (for example, when the total amount of purchase values is greater than the presented amount).
[0045]
Based on the above assumption, the operation of the price determining apparatus 100 will be described.
[0046]
First, the price determination apparatus 100 operates using a buyer input transmitted from the interface 30 as a trigger. Information input from the interface 30 to the buyer information input unit 110 includes a customer ID, a desired product code, the number of items, and negotiation negotiation information. From these pieces of information, the price determination unit 120 accesses the product management database 40 and obtains the sales price of the product (step 201). If there are orders for a plurality of products, all the sales prices are acquired, and the total price of the ordered products is calculated (step 202). Note that the price determination unit 120 holds the number of negotiations and the previous presented amount until the end of the negotiation.
[0047]
Next, the price determination unit 120 reads the sales policy description file 60. In the sales policy description file 60, as shown in FIG. 8, a list of data items of customer information and product information to be used (usage data table), and as shown in FIG. 3): a negotiation table in which conditions for conducting negotiations are written, and a negotiation breakdown table in which conditions for breaking negotiations are written as shown in FIG. Has two tables. Further, the negotiation table may be automatically interpreted to find out the data items of customer information and product information to be used. If there are a plurality of sales policy description files 60 (step 203), the sales strategy from the buyer's terminal 10 can be prevented from being decoded by selecting at random (step 204). By performing these processes, the price determination unit 120 reads the sales policy description file 60 (step 205). Further, the price determining unit 120 accesses the corresponding database from the usage data table of the read sales policy description file 60 and reads the data (step 206).
[0048]
The price determination unit 120 may prepare several methods when determining the negotiation table or the negotiation breakdown table. For example, when the purchase amount is read, a method for defining the total value of the purchase amount as a description can be prepared by describing the total (purchase amount) in the negotiation table or the negotiation breakdown table. That is good. Similarly, the minimum (purchase amount), average (gross margin), etc. can be considered.
[0049]
The price determination unit 120 retrieves a negotiation result that matches the condition written in the negotiation table of the read sales policy description file 60 from the contents of the negotiation negotiation of the buyer, the product information of the ordered product, and the customer information of the buyer (step) 207).
[0050]
If the searched negotiation result is not found, the negotiation is broken, and the fact is transmitted to the interface 30, and the negotiation is completed (step 208, step 213).
[0051]
When one or more search results are found, the notification unit 130 calculates a new price or proposes a product (addition) that can be added free of charge based on the result.
[0052]
Based on the above negotiation, the formula for calculating the new price is as follows.
[0053]
New offer amount = max (previous offer amount x discount rate, negotiation price)
Also, if the buyer enters negotiation negotiation behavior and the negotiation negotiation amount is reached,
New offer amount = previous offer amount x discount rate
It is.
[0054]
Proposal of products that can be added free of charge
SQL formulas etc. are issued to the product management database 40 and proposed at random. For example, if the negotiation condition is to attach a product whose selling price is 500 yen or less,
Where ((Product Management Database. Sales Price) <= 500);
And randomly select from the product list. When the product management database 40 is categorized, products may be selected by narrowing down the conditions. In addition, when there are a plurality of negotiation results, they are selected at random. By selecting at random, it is possible to prevent the buyer from deciphering the sales strategy. Note that the sales price is used as the first presentation amount (steps 208, 209, and 210).
[0055]
The price determination unit 120 reads the negotiation breakdown table of the sales policy description file 60, and when the negotiation breakdown condition is satisfied, the negotiation determination is broken, and the notification unit 130 transmits the fact to the interface 30 and the negotiation is finished (step 211).
[0056]
If the negotiation breakdown condition is not satisfied, the notification unit 130 transmits the new sales amount to the interface 30. The interface 30 merges the result with new product information and a screen (HTML file) that displays a product purchase button, a negotiation input window, and the like, and presents the merged result to the buyer's terminal 10 (step 212).
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0057]
In the following embodiment, an electronic mall operated on a homepage will be described as an example.
[0058]
A buyer who uses the electronic mall for the first time has user registration. User authentication is performed on the start page of the homepage. For example, it is assumed that “Taro Yamada” (customer ID = 1) in FIG. 5 logs in. After authentication, the home page automatically includes a product code, a price, and a list with a number input field as shown in FIG. Move to the homepage where radio buttons for "Purchase more" and "Add bonus", a field for entering the negotiation price, a purchase button, and a negotiation button are displayed. The buyer's information specified as the personal authentication is retained by the electronic mall until the buyer finishes using the electronic mall.
[0059]
The buyer presses the purchase button after entering the number of items to be ordered on the day of obtaining the item to order by looking at a list of prices and the like. For example, enter 1 in each number field of a low-priced personal computer, a 17-inch display, and a color printer, select “More Price” and press the Negotiate button. When the purchase button is pressed, information on the product code and the number of products is posted to the price determination unit 130. In the case of the previous example,
Product code 10001: Number 1;
Product code 20002: Number 1;
Product code 30002: Quantity 1:
Information is posted. In the price determination unit 120 of the price determination apparatus 100, the product management database 40 is accessed, and from the example of FIG.
Product code 10001: Price ¥ 80,000
Product code 20002: Price ¥ 40,000
Product code 30002: Price ¥ 20,000
And the sales price of ¥ 140,000 is calculated.
[0060]
Next, the usage data table of the sales policy description file 60 is read from the customer management database 50.
Customer ID1: Cumulative purchase price ¥ 1,000,000
From the product management database 40,
Product code 10001: Stock number 25: Purchase price ¥ 45,000
Product code 20002: Quantity in stock 20: Purchase value ¥ 28,000
Product code 30002: Stock quantity 50: Purchase price ¥ 15,000
Get each.
[0061]
Next, the search unit 110 reads and matches the negotiation table in the sales policy description file 60. For example, if the date of negotiation is January 1st,
5% discount on sales price
15% discount on sales price
20% discount on sales price
It is.
[0062]
If you choose a 15% discount on the selling price at random, the suggested price is
¥ 140,000 × (10015) / 100 = ¥ 111,000
become.
[0063]
Next, matching of negotiation break conditions is performed. Since there is no one that satisfies the condition, this offer price is transmitted to the interface 30.
[0064]
The interface 30 uses the presented price as a negotiation negotiation action, and displays a radio button for “More discount” and “Add bonus”, a column for entering the negotiation negotiation price, a purchase button, and a homepage on which the negotiation button is displayed. It is displayed on the terminal 10.
[0065]
The buyer “Taro Yamada” next inputs the negotiation price “¥ 100,000” and presses the negotiation button.
[0066]
Assume that the price determining apparatus 100 performs the same processing as described above, and selects a negotiating condition with a 20% discount on the selling price and a Dandam.
[0067]
At this time, the offer price is
max (119,000 x (100-20) / 100, 100,000) = max (95,200, 100.000)
= ¥ 100,000
become.
[0068]
Since this value does not satisfy the negotiation breaking condition, this offer price is transmitted to the interface 30. The interface 30 displays the purchase price and the negotiation negotiation action as the buyer's homepage on which radio buttons “price more” and “add bonus”, a field for entering the negotiation negotiation amount, a purchase button, and a negotiation button are displayed. It is displayed on the terminal 10.
[0069]
The buyer “Taro Yamada” presses a purchase button to close a business negotiation.
[0070]
In the above embodiment, the flowchart shown in FIG. 7 is constructed as a program, and a disk device, floppy disk, CD-ROM, etc. connected to a computer used as a price determination device when implementing the present invention. The present invention can be easily realized by storing it in a portable storage medium and installing it when implementing the present invention.
[0071]
The present invention is not limited to the above-described embodiments, and various modifications and applications are possible within the scope of the claims.
[0072]
【The invention's effect】
As described above, according to the present invention, it is possible to set a price under a condition that is matched to the negotiation by performing the negotiation that matches the purchase condition of the buyer and the sale condition of the seller as electronic commerce on the network. it can. This is because sales conditions can be set flexibly in consideration of not only the price but also the purchase history of the buyer, the status of inventory, etc., making it possible to conduct business negotiations close to the real world.
