  Further, the sales record data D (see FIG. 6) is stored in the HDD 18 as past record data related to discount sales of products. The sales performance data D is statistical data in which the correlation between the discount amount applied to the product in the past and the sales performance of the product when the discount amount is applied is recorded.

  That is, in the sales performance data D, the actual number of items remaining at the time that is a predetermined remaining time with respect to the closing time, the event information of the day such as the weather and holidays, the presence / absence of distribution of the promotional flyer, Other conditions such as special sale date are recorded. In addition, the sales performance data D includes a discount amount (discount rate) applied in the past with respect to these conditions, and the remaining number of products at the sales end time or the sales end time when the discount amount is applied. The sales profit of the product is stored as performance data of the part-time sales.

  The ROM 12 stores various programs executed by the CPU 20 and various data. The RAM 13 functions as a work area for temporarily storing data and programs when the CPU 20 executes various programs.

  The CPU 20 functions as a control unit 21 (see FIG. 9) that controls the management server 2 by reading a program from the ROM 12 and the HDD 18 and developing the program on the RAM 13 and executing it.

  FIG. 9 is a functional block diagram showing a functional configuration of the management server 2. As shown in FIG. 9, the control unit 21 mainly includes a discount condition receiving unit 22, a sales data receiving unit 23, a remaining number management unit 24, a discount amount calculation unit 25, and a display control unit 26. ing.

  The discount condition receiving unit 22 causes the display 17 to display an automatic discount setting screen W (see FIG. 7) for accepting input of various automatic discount conditions such as closing time and weather of the day. The store clerk sets automatic discount conditions from the automatic discount setting screen W before the automatic discount start time or before the store opens.

  FIG. 7 is a diagram showing an automatic discount setting screen W. As shown in FIG. 7, the automatic discount setting screen W includes a field a for selecting or inputting a discount pattern, fields b and c for inputting a product code or a product name, and an automatic discount end time. A column d for entering the closing time and a check box e for selecting whether or not the store is out of stock at the closing time are provided. The automatic discount setting screen W includes a field f for inputting the number of unsold items at the closing time, a field g for inputting a maximum discount rate, a field h for setting automatic discount start conditions, and whether or not a promotional leaflet is distributed. A check box i to be selected and a field j for inputting the weather or event of the day are provided.

  The automatic discount setting screen W is provided with a cancel button k for closing this screen and a setting button m for setting various conditions input on the screen as automatic discount conditions.

  The discount condition accepting unit 22 accepts various conditions related to automatic discount sales entered on the automatic discount setting screen W when the setting button m is clicked on the automatic discount setting screen W (see FIG. 7). The automatic discount condition setting file F (see FIG. 6) of the HDD 18 is stored.

  Here, the closing time is set as the automatic discount end time, but as the automatic discount end time, the sales end time of the product may be input, and the sales end time is set for each product or sales floor. Each may be set.

  In FIG. 7, when the automatic discount start condition is 17:00, or “the value obtained by subtracting the estimated number of products sold at the closing time from the remaining number of products” is 30 or more, that is, the closing time It is set as the case where the remaining number of products at the current time has increased with respect to the predicted number of sales. As described above, by starting the automatic discount with reference to not only the remaining time until the closing time but also the remaining number of products, the automatic discount can be started by appropriately reflecting the sales situation.

  The weather information may be changed by the store clerk from the automatic discount setting screen W when the weather changes, or may be automatically changed. Thereby, the discount amount can be calculated in consideration of changes in weather.

  The sales data receiving unit 23 receives sales data such as the product name and the number of products registered for sale in the POS terminal 4 from the POS terminal 4 via the communication I / F 14.

  The remaining number management unit 24 subtracts the number of sales of the product received by the sales data receiving unit 23 from the remaining number of products stored in the product master M (see FIG. 8), and calculates the remaining number of products at the present time. The calculated remaining number is stored in the product master M to manage the remaining number of products.

  The discount amount calculation unit 25 updates the discount amount or the discount rate by a plurality of discount stages, and automatically sets the discount amount in the part-time sale of the product.

  That is, the discount calculation unit 25 is set in the automatic discount condition setting file F when the remaining time until the closing time reaches a predetermined time (for example, remaining 3 hours, remaining 2 hours, remaining 1 hour). Using the automatic discount conditions, the product information (remaining number, discount amount, etc.) of the current product 7 stored in the product master M, and the sales performance data D, these data are subjected to multiple regression analysis and correlation By applying a statistical method such as analysis, the predicted number of sales of the product 7 at the closing time is calculated.

  Then, the discount amount calculation unit 25 calculates the discount amount data when the remaining number of products at the closing time is statistically minimum from the sales performance data D with respect to the calculated predicted sales number, or at the closing time Extract discount data when the product sales profit is statistically maximum. The discount calculation unit 25 calculates the discount (optimum discount) of the product 7 based on the extracted discount data and the remaining time until the closing time.

  The discount calculation unit 25 calculates an optimal discount based on the automatic discount conditions set in the automatic discount condition setting file F. For example, when the discount amount calculated using the predicted sales volume is larger than the maximum discount rate set on the automatic discount setting screen W as described above, the maximum discount rate is set as the optimum discount rate.

  Furthermore, the discount calculation unit 25 calculates the predicted sales number of the product up to the closing time when the optimal discount calculated as described above is applied.

  Further, the discount calculation unit 25 calculates a discount when selling the next day for the product 7 (see FIG. 8) that has not been sold that day after the closing time. As an example, the discount calculation unit 25 applies the maximum discount rate (three discounts in FIG. 7) input on the automatic discount setting screen W as the discount rate at the next day sale.

  The display control unit 26 displays the optimum discount amount calculated by the discount amount calculation unit 25 on the display device 3 as shown in FIGS. 2 and 3 and functions as a notification unit that notifies the customer of the current discount amount. .

  Further, the display control unit 26 shows an instruction to affix the discount label L of the discount of the next day calculated by the discount calculation unit 25 to the unsold item 7 after the closing time in FIG. As shown in FIG. Thereby, the store clerk can affix the discount label L of the optimal discount rate to the unsold product 7 after the store is closed, so that the work efficiency after the store is closed can be improved.

  In addition, since the maximum discount rate set in the automatic discount condition setting file F is applied to the unsold product 7, the product 8 processed on the day (see FIG. 11) and the previous day's product were processed at the next day of sale. Even when the unsold product 7 is displayed on the product display shelf 6, the cheaper one-day processed product (product 7) can be easily purchased. Therefore, it becomes possible to quickly sell the processed product (product 7) on the previous day and reduce the number of products discarded due to expiration of the expiration date.

  In addition, as shown in FIG. 11, the display control unit 26 causes the display device 3 to display display information other than the discount display such as a sales promotion message when automatic discount is not performed such as immediately after opening a store. Thereby, the display apparatus 3 can be utilized for multiple purposes over the whole business hours.

  The discount amount registration unit 27 registers the discount amount calculated by the discount amount calculation unit 25 in the product master M (see FIG. 8). As a result, the POS terminal 4 can register the sale of the product by reflecting the discount amount. When automatically discounting the product, the clerk's clerk automatically performs the value without performing a new operation. You can pull out.

  Next, a discount display process performed by the management server 2 will be described with reference to FIG. FIG. 12 is a flowchart for explaining the procedure of the discount display process performed by the management server 2.

  First, the sales data receiving unit 23 determines whether or not sales data such as a product name and a sales quantity of a product registered for sale has been received from the POS terminal 4 (step S1). If not received (step S1: No), the process proceeds to step S3. When the sales data is received (step S1: Yes), the remaining number management unit 24 calculates the remaining number of products based on the received sales data, and stores the calculated remaining number in the product master M (step S2). ).

  Then, the discount calculation unit 25 determines whether or not the predetermined remaining time has been reached with respect to the closing time (step S3), and when the predetermined remaining time is not reached (step S3: No), step S1. Return to. On the other hand, when the predetermined remaining time is reached (step S3: Yes), the discount calculation unit 25, the automatic discount condition set in the automatic discount condition setting file F, the product master M, the sales record An optimal discount rate is calculated using data D and the like (step S4). The display control unit 26 displays the optimum discount rate calculated in step S4 on the display device 3 (step S5). Further, the discount amount registration unit 27 registers the optimum discount rate calculated in step S4 in the product master M (step S6).

  The discount calculation unit 25 determines whether or not the store closing time has come (step S7). If it is not the closing time (step S7: No), the process returns to step S1, and the processing of steps S1 to S7 is continued until the closing time is reached, and the discount rate is set according to the remaining time and the remaining number of products. The process of updating in stages and displaying on the display device 3 is continued.

  Here, when the discount rate is updated step by step by the management server 2 from the first discount stage to the fifth discount stage, an example of the predicted sales number and the optimal discount rate calculated by the discount amount calculation unit 25 Show. As the automatic discount condition, the automatic discount is updated every 1 hour from 17:00 for the closing time 21:00 using the conditions set on the automatic discount setting screen W of FIG. Shall.

First discount stage start time 17:00
Remaining time 4 hours Product remaining number 124 Estimated number of sales until closing time 100 ± 10 Estimated number of sales at the first discount stage 40 ± 10 Optimal discount rate Until closing time when 1 discount optimal discount rate is applied Expected sales of 120 ± 10

Second discount stage start time 18:00
Remaining time 3 hours Remaining product number 107 Estimated number of sales until closing time 80 ± 10 Estimated number of sales at the second discount stage 50 ± 10 Optimal discount rate Until the closing time when 2 discount optimal discount rate is applied Expected sales of 100 ± 10

3rd discount stage start time 19:00
Remaining time 2 hours Product remaining 43 Estimated sales until closing time 40 ± 5 Estimated sales at third discount stage 20 ± 5 Optimum discount rate Until closing time when 2 discount optimal discount rate is applied Expected sales of 40 ± 5

4th discount stage start time 20:00
Remaining time 1 hour Product remaining 29 Estimated number of sales until closing time 20 ± 5 Estimated number of sales at 4th discount stage 20 ± 5 Optimal discount rate Up to closing time when 2.5 discount optimal discount rate is applied Estimated number of sales 25 ± 5

5th discount stage start time 20:30
Remaining time 30 minutes Product remaining 20 Estimated sales up to closing time 20 ± 2.5 Estimated sales in 5th stage 20 ± 2.5 Optimum discount rate Predicted until closing time when 3 discount optimal discount rate is applied Number of sales 20 ± 2.5

  As a result, at the closing time 21:00, for example, the remaining number of products 7 can be two. Accordingly, it is possible to achieve the condition of “the number of remaining unsold at the closing time of 4 or less” set on the automatic discount setting screen W.

  When the store closing time is reached in step 7 (step S7: Yes), the discount amount calculation unit 25 calculates the discount rate when selling the next day for the unsold item 7 (see FIG. 10). Then, the display control unit 26 displays a work instruction to affix the discount label L of the calculated discount rate on the product 7 on the display device 3 (step S8), and ends the process.

  As described above, according to the management server 2 according to the present embodiment, the remaining time with respect to the closing time, the remaining number of products, and the like are collated with the sales result data D of past discount sales, and are statistically optimal. Calculate the discount amount. Therefore, there is an effect that it is possible to easily determine the discount amount that maximizes the sales profit or the discount amount that minimizes the remaining number of the products 7 without determining the discount amount depending on the intuition of the store clerk.

  Further, since the optimum discount amount is displayed on the display device 3 immediately after the calculation, it is possible to omit the work of attaching the discount label by the store clerk, and the work load of the store clerk for the part-time sale is reduced, and the value of the product is reduced. It is easy to carry out pull sales.

  In the above description, the display control unit 26 displays the discount amount of the product on the display device 3 to notify the customer of the discount amount. However, the discount amount notification method is not limited to this. As another example, a speaker may be provided in the vicinity of the merchandise display shelf 6 to notify the customer of the discount amount by voice.

  In the above description, the discount start time and the start time of each discount stage are, for example, 4 hours before the closing time (360 minutes before), but the discount start time may be determined randomly. desirable. Therefore, the discount start time may be set 355 minutes before the store closing time or 364 minutes before the closing time using random numbers.

  In the above description, an example in which a discount rate is displayed as the discount information displayed on the display device 3 is shown, but the example of the discount information is not limited to this. The management server 2 may update the discount amount in stages, for example, “100 yen discount”, “50 yen discount”, etc., and display it on the display device 3.
