Here, the weighting value is a numerical value assigned to each menu group depending on the season, climate, time zone, etc. For example, if the season is winter, ingredients related to menus such as “oden” and “nabe” Are sold well, the weighting values corresponding to the menu groups of “oden” and “nabe” are set high and registered in the table. Note that the weighting value is a weighting value suitable for the product or group when the definition of the product or group is different from the present embodiment, for example.

Next, the processing flow of the price management system will be described.
FIG. 6 is a diagram showing a processing flow when changing the price displayed on the wireless electronic shelf label.
From FIG. 6, first, after each process, when the price of a certain product is changed, that is, the price change unit 106 displays the price of the product recorded in the product information storage 103 of the price management apparatus 1. When the price is changed to a changed price based on an instruction or the like, the price changing unit 106 notifies the transmission instructing unit 105 of information indicating the change. Then, the transmission instruction unit 105 reads the identification number of the product whose price has been changed and the price of the product from the product information storage unit 103, and transmits a transmission instruction of information on the combination of the identification number and the price to the wireless transmitter 2. The communication processing unit 101 is notified. Then, the communication processing unit 101 receives the combination information and the transmission instruction information from the price changing unit 106 and transmits them to the wireless transmitter 2 via the communication network (step S1).

  Next, the network processing unit 22 of the wireless transmitter 2 receives the information of the combination of the identification number and the price from the price management device 1 and the information of the transmission instruction, and the control unit 23 identifies based on the received information. The wireless transmission processing unit 21 is notified of a transmission instruction for information on a combination of a number and a price. Then, the radio | wireless transmission process part 21 transmits the radio signal containing the information of the combination of an identification number and a price from the antenna 20 (step S2).

The wireless reception processing unit 31 of the wireless electronic shelf label 3 receives the wireless signal transmitted from the wireless transmitter 2 via the antenna 30 (step S3). Then, the control unit 33 reads the identification number and price information included in the radio signal (step S4). Then, the control unit 33 checks whether or not the read identification number matches the identification number recorded in the identification number storage unit 32 (step S5). If they match, the control unit 33 has already been displayed on the liquid crystal screen 34. The displayed price is changed to the price read from the radio signal and displayed (step S6).
Thereby, in the price management apparatus 1, when the price of a product is changed by the product manager, the information can be immediately reflected on the wireless electronic shelf label 3 provided on the shelf of each product on the sales floor. Therefore, it is possible to reduce the labor such as changing the price tag of the administrator.

Next, processing of the price management device at the time of price change will be described.
First, the price management device 1 is provided with an input unit (keyboard or mouse) that receives an instruction from an administrator, and the price change unit 106 receives a price change request for a specific product based on an input from the input unit. . Then, the price changing unit 106 reads the current price of the received specific product from the product table stored in the product information storage unit 103, and monitors the price change screen displaying the information on the specific product and the price information on the monitor 107. To display. When the administrator inputs a change price and a change instruction using the price change screen, the price change unit 106 rewrites the price of the specific product in the product table with the change price. When the price changing process is completed, the price changing unit 106 starts the process for correcting the display of the wireless electronic shelf label 3 as described above.
When the price change unit 106 receives information on the menu group at the time of the price change request, all the products belonging to the menu group (that is, whether the flag belongs to the menu group is “1”). The price change screen displaying the information on the product and the price thereof may be displayed on the monitor 107.

FIG. 7 is a diagram showing a processing flow when changing the price of another product related to the price-change product.
In addition to the above processing, the price management device 1 performs a process of changing the price of another related product based on the price change of the product when the price of the product is changed.
As shown in FIG. 7, first, when the price of a product is changed, the price changing unit 106 notifies the related product specifying unit 108 of the product code of the product whose price has been changed (hereinafter referred to as “price changed product”). Then, the related product specifying unit 108 reads the product attribution group information (a table indicating whether the food product belongs to the menu group with a flag of “0” or “1”) from the product table, and the information. Based on, a related product specifying matrix M is generated (step S71). Here, the related product specifying matrix M is a menu group in which the flag of the price-changed product is 0 in the matrix directly represented by the arrangement of the “0” and “1” flags of the product attribution group information in the product table. This is a matrix in which all the flags of other products belonging to (that is, the flag is “1”) are changed to “0”. When the number of products is i and the number of menu groups is j, the related product specifying matrix M is an i row and j column matrix.

  In addition, the related product specifying unit 108 reads the weight values recorded in the weighting table of the product information storage unit 103, and generates a weighting matrix W (step S72). The weighting matrix W is a matrix that is expressed as it is in the sequence of weight values recorded in the weighting table, and is a matrix of j rows and 1 column.

Here, if the set of menu groups to which the price-change product belongs is N, the relevance R _i of the other product i with respect to the price-change product is expressed by Expression (1).

M _ij in the equation (1) indicates one matrix element (value of i rows and J columns) in the related product specifying matrix M. Then, the related product identification unit 108 calculates “M ₁₁ × W ₁ + M ₁₂ × W ₂ + M ₁₃ × W ₃ +... + M _ij × W _j ” by this formula, and the price of the product of i = 1 The degree of association with the changed product is calculated, and similarly, the degree of association with the price-changed product of each product is calculated (step S73). That is, the matrix of m rows and 1 column calculated by the equation (1) represents the degree of relevance of each product to the price-change product, and among them, the value of the price-change product is a value indicating the highest value. The other products that are closer to the value are products that have a higher relevance to the price-change product.
FIG. 8 is a diagram showing an outline of the processing of the related product specifying unit.

As shown in FIG. 8, the related product specifying unit 108 first generates a related product specifying matrix M from the matrix of the product attribution group information obtained from the product table, and the related product specifying matrix M and the weight matrix W And the degree of relevance for the price-changed product is calculated according to the equation (1). Then, the related product specifying unit 108 specifies a product other than the price-change product with the highest value from the calculated relevance value (step S74).
Note that the specification of other products having a high degree of association with the price-change product may be other than a method for specifying a plurality of products having a high degree of association, and this process is arbitrarily set. Then, the related product specifying unit 108 notifies the loss distribution unit 110 of the product codes of the three specified products.

  Next, when the related product specifying unit 108 completes specifying the product highly relevant to the price-changed product, the loss amount calculating unit 109 is based on the price before the change of the price-changed product, the changed price, and the number of purchases. Then, the loss amount P is calculated (step S75). The loss amount P is calculated by equation (2). In Formula (2), the price-change product is “potato”, the price before the change is “y” in FIG. 4, the purchased quantity is “β” in FIG. 4, and the change price is “Y”. Is a formula for calculating the loss amount P.

  Next, the loss amount distribution unit 110 performs a process of adding the loss amount to the price of the product specified by the related product specifying unit 108 (step S76). Here, in the loss amount distribution unit 110, the product specified by the related product specification unit 108 is “onion”, the selling price of the “onion” is “z” in FIG. 4, and the purchased quantity is in FIG. In the case of “γ”, the price K of “onion” is calculated using Expression (3) <Allocation calculation expression>.

As a result, it is possible to calculate a price obtained by adding the amount of loss when the price of potato is changed to the price of onion.
Then, the loss amount distribution unit 110 notifies the price change unit 106 of the calculation result as a change price of “onion”. That is, the onion product code and the value of the change price are notified. As a result, the price changing unit 106 starts processing for rewriting the onion price recorded in the product table of the product information storage unit 103 with the changed price, and processing for correcting the display of the wireless electronic shelf label 3 of the onion. (Step S77).

With the above processing, the loss due to the price change can be added to the price of the other product highly related to the product whose price has been changed. For example, when the price is reduced with potato as a special sale item, the potato You can raise the price of highly relevant products used in the same dish (menu). So, for example, if you look at a special product called potatoes and the purchaser wants to use the dinner menu as curry rice, if you purchase the potato and other ingredients used for curry rice, the total will be reflected in potatoes. Since the loss due to the special sale price can be added to other products, it is possible to reduce the loss of sales.
In addition, according to the present invention, the product manager can appropriately set the weighting for each menu group, so that the product whose price is changed and the product having a high degree of relevance can be appropriately changed. Each product can be promoted.
In addition, when a menu group is specified, the price of the ingredients related to the menu group can be changed, and the price of the wireless electronic shelf label 3 of each ingredient can be changed at a time. Thus, it is possible to promote sales of each product to consumers efficiently.

  Each of the above devices has a computer system inside. The process described above is stored in a computer-readable recording medium in the form of a program, and the above process is performed by the computer reading and executing this program. Here, the computer-readable recording medium means a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like.
