Description

  The present invention relates to a merchandise management system and merchandise management method for managing the remaining quantity of merchandise.

  In a mass retailer, etc., if a shopper takes out a product from the product display shelf for purchase and the product disappears from the product display shelf or the remaining quantity of the product decreases, the store clerk Must be replenished and displayed.

  FIG. 7 shows a replenishment display method for commodities according to a conventional example. In this example, the store clerk 71 goes around the store and monitors the presence or absence of the product 73 in each product display shelf 72. When the clerk 71 finds that, for example, the merchandise 73c on the merchandise display shelf 72c is missing or is remaining, the clerk 71 notifies the clerk 75 arranged in the warehouse 74 to that effect. Upon receiving this notification, the store clerk 75 carries out the product 73c from the warehouse 74 and performs a replenishment display on the product display shelf 72c. Alternatively, as shown in FIG. 8, the clerk 71 who has confirmed the remaining quantity of the product 73c in the product display shelf 72c goes directly to the warehouse 74 and carries out the supplementary display by carrying out the product 73c.

  FIG. 9 shows another replenishment display method according to a conventional example (see, for example, Patent Document 1). In this method, the remaining number of products in the product display shelf 72 is determined based on information from the POS terminal 91. That is, when the shopper 92 purchases the product 73 at the cash register, the purchase information is sent from the POS terminal 91 to the control / management unit. Based on the number of items sold in the purchase information, the control / management unit calculates the remaining number of products 93 for each product display shelf 72, and determines whether or not there are no more products. If it is determined that there are no more products or the remaining items are low, the control / management unit sends a notification to the upper device 94 of the warehouse 74 to request replenishment of the products. When this notification is received by the host device 94, the store clerk 75 of the warehouse 74 takes out the product from the warehouse 74 and performs replenishment display on the corresponding product display shelf 72.

  However, according to the method of FIG. 7 and FIG. 8 described above, the store clerk goes around the store and directly checks the remaining quantity of the product on the product display shelf. May remain unfilled in the merchandise display shelf. In addition, when there are product display shelves in the store where there are no or few products due to fast sales, there is a risk that the shop staff will not be able to keep up with the patrol check work and the replenishment display work. In this case, the merchandise display shelf is sold out, and an opportunity for selling merchandise is missed. Increasing the number of shop assistants may avoid these problems, but it will cause another problem such as an increase in personnel costs.

  In addition, according to the system using the POS terminal shown in FIG. 9, the problem such as the above-mentioned check omission of the store clerk is solved, and the product to be replenished can be known without performing the check operation by the store clerk. Can perform replenishment display very efficiently. However, according to this system, the remaining quantity of the product is calculated only when the shopper purchases the product at the cash register. The product remaining quantity is not calculated when the product is taken out from the product display shelf. Therefore, to give an extreme example, as shown in FIG. 9, when the main product 73c, which is a special sale item for that day, exists in the product display shelf 72c, the shoppers 92a and 92b first have the product 73c as another shopper 92c. If the product 73c is first searched and the product 73c can be secured, other shopping may be performed slowly. Then, it takes a considerably long time for the product 73c to be taken out from the product display shelf 72c and purchased at the cash register.

  In this case, even if, for example, six items 73c are taken out and the item 73c disappears in the item display shelf 72c, the shoppers 92a and 92b who have taken away the item 73c eventually do not purchase the item 73c at the cash register. As long as the merchandise 73c is not reflected in the remaining number calculation, it is still recognized that six of the merchandise 73c remain in the merchandise display shelf 72c. That is, a time zone in which the product is sold out occurs. In this case, the shopper 92c determines that the product 73c has been sold by looking at the situation in which the product 73c has disappeared from the product display shelf 72c. Thereby, although the goods 73c are in stock in the warehouse 74, the opportunity to be purchased by the shopper 92c is lost. Therefore, in reality, it does not completely depend on the system using the POS terminal, and a store clerk 71 who visits the store to some extent is also required.

  As described above, the cause of missing the opportunity to sell a product is caused by the shopper determining that the product has been sold out in view of the situation where the product has disappeared from the product display shelf despite the stock in the warehouse. Even if there are no products on the product display shelf, if the store clerk is informed that the store is still in stock and the store clerk is currently carrying the product from the store, it is avoided that the product is sold out. However, such information is not transmitted to the shopper in the system of FIG. In some cases, the shopper checks directly with the store clerk whether the item is completely sold out or is in stock in the warehouse. However, in that case, it is necessary to search for and ask the store clerk in the store, which increases the burden on the shopper.

  FIG. 3 is a flowchart showing the flow of processing in the inventory management system of FIG. As shown in the figure, first, in step 31, the goods are carried out from the warehouse 21, or the goods are carried in from the ordering party. At that time, the remaining quantity of goods in the warehouse 21 fluctuates when the carry-out or carry-in is performed. The merchandise is carried out by the store clerks A and B in order to perform the replenishment display on the merchandise display shelf 11 before the start of business or when a replenishment request is made.

  In accordance with the change in the remaining product quantity in the warehouse 21, in step 32, the remaining product quantity detection device 24 notifies the inventory management control unit 22 of the remaining product quantity after the change in the warehouse 21. Based on this notification, the inventory management control unit 22 updates the warehouse product remaining quantity in the management table for the product in which the remaining product quantity has changed in step 33. Thereby, the remaining product quantity at the time of starting business is also determined. At that time, for products that do not require replenishment display and there is no change in the remaining product quantity, the remaining product quantity is not updated, and the final product remaining quantity of the previous day is used as it is as the remaining product quantity at the start of business. Value.

  Next, in steps 34 and 35, the inventory management control unit 22 determines whether or not ordering is necessary for each product based on the remaining product quantity at that time, and performs ordering processing for the product determined to be necessary.

  Next, in step 36, when the store clerk replenishes the product on the product display shelf 11 or the shopper takes out the product to be purchased from the product display shelf 11 after the start of business, the remaining product quantity on the product display shelf 11 changes. To do. In response to this, in step 37, the remaining product quantity detection device 23 notifies the inventory management control unit 22 of the remaining product quantity for the product whose remaining product quantity has changed. Based on this notification, in step 38, the inventory management control unit 22 updates the display shelf product remaining quantity in the management table for the product whose remaining product quantity has changed.

  Next, in step 39, the inventory management control unit 22 determines whether the updated display shelf product remaining quantity of the product is below a predetermined amount. If it is determined that the product has fallen below, in order to perform the product replenishment process for the product, the inventory management control unit 22 in step 40 only finds that the product on the product display shelf 11 is not yet on the display shelf product remaining quantity. Determine if a small amount is present. If it is determined that there is a small amount, it is not necessary to particularly notify the shopper of the stock status and the replenishment status of the product, so the knowledge inventory management control unit 22 proceeds directly to step 41 and the mobile radio of the clerk A and B A product replenishment request for the product is transmitted to the machine. Thereafter, in steps 31 to 38, a replenishment process for the product is performed.

  If it is determined in step 40 that the product does not exist, it corresponds to a case where the product is sold too quickly or a predetermined amount based on the determination in step 39 is set to 0 (zero) At this time, since the product does not exist on the product display shelf 11, a process for notifying the shopper of the stock and replenishment status of the product is performed. That is, the inventory management control unit 22 first determines in step 42 whether or not there is an inventory in the warehouse 21 for the product. This determination can be made based on the number of remaining warehouse items in the management table. If it is determined that the product is in stock, the process proceeds to step 43, and a message display request is made to the liquid crystal display device 25 of the product display shelf 11 of the product, such as “I will bring it now”. In response to this request, the liquid crystal display device 25 displays the message in step 44. Thereafter, in step 45, the inventory management control unit 22 transmits a merchandise replenishment request for the merchandise to the clerk A and B portable wireless devices. Thereafter, in step 31, the store clerk A or B carries out the product from the warehouse 21 in order to replenish the product.

  If it is determined in step 42 that the product is not in stock, the inventory management control unit 22 proceeds to step 46 and sends a message to the liquid crystal display device 25 indicating that the product has been sold out. Make a display request. In response to this request, the liquid crystal display device 25 displays the message in step 47. After that, since there is no stock of the product in the warehouse 21, the replenishment request for the product to the clerk A and B is not performed until the product is newly delivered. That is, for the product, the process of FIG. 3 is finished, and the product is in a standby state. When the product arrives and is carried into the warehouse 21, the process for the product starts from step 31.

  On the other hand, if the inventory management control unit 22 determines in step 39 that the updated display shelf product remaining quantity of the product does not fall below the predetermined amount, it is not necessary to replenish the product. In 48, it is determined whether or not “I will bring it now” is displayed for the product in the process of step 44. If it is determined that this display has been made, the inventory management control unit 22 in step 49 determines that the product has just been replenished in step 36 in response to the product request in step 45. It requests the liquid crystal display device 25 to clear the display. In response, the liquid crystal display device 25 clears the display in step 50. Thereafter, when the shopper takes out the product, the processing from step 36 is performed on the product. If it is determined in step 44 that “I will bring it now” is not displayed, it is not necessary to clear the display on the liquid crystal display device 25, so that the shopper takes out the product as it is in step 36. Will wait to do.

  FIG. 4 shows an example of the product replenishment display work performed in accordance with the process flow of FIG. As shown in the figure, when a shopper takes out a desired product from the product display shelf 11, the product remaining amount detection device 23 of the product display shelf 11 sends the remaining product quantity of the product to the inventory management control unit 22. (Step S1 in FIG. 4; step 37 in FIG. 3). Based on this notification, the inventory management control unit 22 updates the display shelf product remaining quantity in the management table for the product (step S2; step 38). At this time, if the inventory management control unit 22 determines that the product display shelf 11 needs to be replenished for the product (step S3; step 39), if the product is in stock in the warehouse 21, each clerk A And B are notified of a replenishment request for the product (procedures S4 and S5; steps 41 and 45). Based on this notification, the clerk A in a state where the replenishment display work is possible responds to the inventory management control unit 22 with a message of “replenishment approval” (step S6). Note that the clerk B who is in a state where the replenishment display work cannot be performed does not respond to the replenishment request. Upon receipt of the “replenishment approval” message from the store clerk A, the inventory management control unit 22 notifies the store clerk A that the store clerk A is in charge of the replenishment display of the product (step S7). Further, in order not to perform the replenishment display work twice, since the current replenishment display is handled by the clerk A, the other clerk B is notified that the replenishment display request is withdrawn (step S8).

  When the clerk A carries the product out of the warehouse 21 for replenishment display (S9; Step 31), the calculated product quantity of the product in the warehouse 21 fluctuates. Is notified to the inventory management control unit 22 (S10; step 32). Based on this notification, the inventory management control unit 22 updates the warehouse product remaining quantity in the management table for the product (S11; step 33).

  When the store clerk A carries the product carried out from the warehouse 21 into the store 10 and performs replenishment display on the corresponding product display shelf 11 (S12; step 36), the remaining product quantity on the product display shelf 11 changes. . In response to this, the remaining product quantity detection device 23 of the product display shelf 11 notifies the inventory management control unit 22 of the remaining product quantity after the change (S13; step 37). Based on this notification, the product remaining quantity detection device 23 updates the display shelf product remaining quantity in the management table for the product (S14; step 38). Thereby, the basic replenishment display work is completed.

  In addition, when the remaining product quantity in the product display shelf 11 immediately before the product replenishment display is performed is 0 (zero), the liquid crystal display device 25 of the product display shelf 11 “have it now”. Is displayed (step 44), and after the completion of the supplementary display for the product, when the remaining product quantity exceeds a predetermined amount that is a criterion for determining whether or not the commodity supplementary display is necessary (step 39). The inventory management control unit 22 issues a command to clear the display to the liquid crystal display device 25 (steps 48 to 49), and when the liquid crystal display device 25 clears the display accordingly (step 50), The replenishment display work for the product has been completed.

  According to the present embodiment, the product remaining quantity in the product display shelf 11 is detected by the product remaining quantity detection device 23, and the inventory management control unit 22 determines whether or not the product replenishment is necessary based on the detection result. It is possible to determine whether or not the product needs to be replenished without having to visually grasp the status of the product display shelf 11 while the store clerk goes around. Based on the determination result, the store clerk is notified of the product replenishment request as necessary. This eliminates the situation where the store clerk is left without being replenished with the necessary product due to omission of confirmation from the store clerk. it can. Further, since there is no need for the patrol work, even if the product display shelves 11 that require the product replenishment display are generated in various places, the replenishment display work can be performed efficiently. In addition, it becomes possible to allocate the time of the traveling work that is no longer necessary to other work. Since the replenishment display work is performed efficiently, it is not necessary to introduce a large number of salesclerks and labor costs can be reduced.

  Further, since the product replenishment request is made based on the product remaining quantity notified by the product remaining quantity detection device 23 at the timing when the product is removed from the product display shelf 11, the product replenishment is performed at the timing when the product is liquidated. Compared to a system using a conventional POS terminal that makes a request, the time for the product to be sold out in the product display shelf 11 can be greatly reduced.

Further, when the liquid crystal display device 25 is provided on the product display shelf 11 and the remaining product quantity in the product display shelf 11 becomes zero, the product is being replenished, or the product is completely sold out. Since this is displayed, the shopper can know the replenishment status and stock status of the product based on this display. Therefore, it is possible to prevent the shopper from erroneously determining that the product is sold out even though the product is still in stock. Therefore, it is possible to prevent the opportunity for selling products from being lost. Moreover, it is possible to prevent the shopper from being burdened with the trouble of inquiring the store clerk about the stock status of the product.

  Furthermore, since the remaining product quantity detection devices 23 and 24 are provided, inventory management, product ordering, a product replenishment request, and notification of stock / replenishment status to a shopper can be performed without the need to introduce a POS system. . In addition, since the communication between the inventory management control unit 22 and the remaining product quantity detection devices 23 and 24, the liquid crystal display device 25, and the portable wireless device 26 is performed wirelessly, the product is changed by changing the layout in the store 10 or the like. Even when the arrangement of the display shelves 11 is changed, the product management system can be easily installed and introduced.
