Description

  The present invention is a product that is individually assigned an in-store code in each retail chain, and a code management server that performs code management for a product that is newly assigned a product identification code every time the material used is updated, And a code management method.

  Conventionally, in a store such as a supermarket, there has been a POS system that collects information for grasping the sales status of each product by reading a POS code such as a barcode attached to a product desired to be purchased. Widely used (see, for example, Patent Document 1-2).

JP 2005-165629 A Japanese Patent Laid-Open No. 2005-228021

  In the conventional POS system described above, the information obtained by the POS code is an in-store code unique to each store. In the chain store, an international standard code format called JAN (EAN) code is generally used. However, in-store codes with different registered corresponding products are used.

  On the other hand, a product master is created for each product sold in each chain store, and a product master number is assigned to each product master. This merchandise master number can uniquely identify the merchandise sold at each chain store.

  Therefore, if the in-store code and the product master number used in each chain store are associated with each other on a one-to-one basis, it is possible to accurately obtain information on the corresponding product from the in-store code in each chain store.

  However, in practice, for example, if some ingredients in a product such as side dish or canned food are changed, the product master number is assigned separately, but the in-store code continues without being changed. Therefore, there is a problem that accurate information about the corresponding product cannot be obtained from the in-store code.

  This invention solves the problem mentioned above, and makes it possible to accurately confirm information of each product indicated by an in-store code that is separately assigned and used between a plurality of stores without being unified. Objective.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing an example of the configuration of a code management system 100 according to an embodiment of the present invention. As shown in FIG. 1, the code management system 100 includes a code management server 10, a merchandise master server 20, and retail store servers 31 to 3N (N: any positive integer). The code management server 10, the product master server 20, and the retail store servers 31 to 3N are each connected to a communication network 40 such as the Internet, for example.

  The code management server 10, the merchandise master server 20, and the retail store servers 31 to 3N are each configured by an information processing device such as a WWW server.

  The code management server 10 is a server managed by a system administrator of the code management system 100, for example, and is used at a manufacturing code given to a product when the product is produced or manufactured, or at each retail store. It manages in-store code.

  The code management server 10 includes a code management DB 11 that stores code management information and a manufacturer production management DB 12 that stores manufacturer production management information. The code management information is information for managing the relationship between the manufacturing code and the in-store code used at each retail store. The manufacturer production management information includes the manufacturing code given to the product by the manufacturer when the product is produced or manufactured, the product name of the product indicated by the manufacturing code, and the name of the manufacturer that produced or manufactured the product. Including. The code management DB 11 and the manufacturer production management DB 12 may be inside or outside the code management server 10. The manufacturer production management information is transmitted, for example, periodically from the manufacturer terminal (not shown) managed by each manufacturer to the code management server 10 via the communication network 40 and accumulated in the manufacturer production management DB 12. .

  The merchandise master server 20 includes a merchandise master DB 21 in which a merchandise master (product chart) including various information related to the merchandise such as merchandise history information including merchandise production history and distribution history is stored. The merchandise master includes a merchandise master number (an example of a merchandise chart code) for uniquely identifying the merchandise and a manufacturing code assigned to the merchandise (see FIG. 4). The product master DB 21 may be inside or outside the product master server 20.

  Each of the retail store servers 31 to 3N is managed by, for example, a retail chain manager who manages each of the retail chains A to N, and stores the POS information used in each of the retail chains A to N. 3Na is provided. The retail store servers 31 to 3N are installed in the retail chains A to N, for example. Although not shown in the retail store servers 31 to 3N, a POS register used in each retail chain A to N (a register installed at a purchase amount payment place, for example, for a POS system attached to a product) Various functions such as reading a bar code (an example of a POS code: hereinafter referred to as a POS bar code) and printing purchase contents on a receipt using a product name and a product price specified based on the POS bar code Or a computer that performs POS data intra processing before the processing of the retail store servers 31 to 3N.

  FIG. 2 is an explanatory diagram illustrating an example of POS information stored in the retail chain product master DB 31a included in the retail store server 31 installed in the retail chain A. As shown in FIG. 2, the POS information includes a product name, an in-store code, a manufacturing code, and a product price. The in-store code may be a specific standard format such as a JAN format, or may have a store-specific format. The in-store code is a POS code that is currently used in association with a predetermined product in the POS system in the corresponding retail chain A.

  As shown in FIG. 2, the names of products such as canned foods A and seasonings A and / or supplier names (manufacturer names) are set as the product names. Moreover, the price of the sales unit for every number and weight is set to the price.

  The POS information is stored in each retail chain product master DB 31a to 3Na provided in each retail store server 31 to 3N. Also, different in-store codes may be set for the POS information even for the same product depending on the POS system employed in each store.

  FIG. 3 is an explanatory diagram illustrating an example of code management information stored in the code management DB 11. As shown in FIG. 3, the code management information is information in which a product name, a manufacturing code, a retail chain name, an in-store code, and an application period are associated with each other. The application period means the period applied to the product with the corresponding manufacturing code (or the product chart code associated with the manufacturing code). If it is still applied, the period end date is fixed. Because it is not possible, “Continuing use (applicable)” is set. The application period may be managed not in units of days but in units of months, weeks, hours, minutes, and seconds. In this example, even if the material used for a product is updated and a new manufacturing code is assigned, products with the same name produced with the material used before the update are shipped and sold in duplicate. It may be done. Specifically, in the canned food A shown in FIG. 3, the product before use material renewal and the product after use material renewal are in the same period (August 16, 2006 to October 15, 2006). It is supposed to be shipped and sold.

  FIG. 4 is an explanatory diagram illustrating an example of a product chart stored in the product master DB 21. As shown in FIG. 4, the product chart includes the product name of the product, the manufacturing code uniquely assigned to the product, the product chart code uniquely assigned to the product, and the product. This is information in which used materials are associated with used material history information indicating production and distribution history of each used material.

Next, the operation of the code management system 100 of this example will be described.
FIG. 5 is a flowchart illustrating an example of code management information registration processing executed by the code management server 10 in the code management system 100 of the present example. The code management information registration process is executed, for example, when instructed by an operator of the code management server 10 or periodically (for example, once a day in the early morning or late at night).

  In the code management information registration process, the code management server 10 firstly, among the manufacturer production management information stored in the manufacturer production management DB 12, the manufacturer production management information newly registered (registered since the last acquisition). Is read (step S101).

  Next, the code management server 10 newly registers the product name and the production code included in the acquired manufacturer production management information in the corresponding items of the code management information stored in the code management DB 11, and uses correspondingly. The use start period of the manufacturing code (the start period of the application period) is registered in the period item (step S102).

  Next, the code management server 10 acquires POS information newly registered (registered after the previous acquisition) from each of the retail store servers 31 to 3N (step S103). In step S103, only the manufacturing code and the in-store code may be acquired from the POS information.

  Next, the code management server 10 registers the in-store code and the retail chain name in association with the code management information including the manufacturing code included in the POS information acquired in step S103 (step S104). If the in-store code is already associated with the code management information including the manufacturing code included in the POS information, the code management information including the manufacturing code included in the POS information is copied, and then the in-store code or retail The in-store code and retail chain name are registered by updating the chain name to that included in the POS information.

  In this example, when there is a change in the material used for the corresponding product, the manufacturer production management information with the updated manufacturing code is newly registered in the manufacturer production management DB 12. In this example, the manufacturer production management information including the pre-update manufacturing code remains in the manufacturer production management DB 12 without being deleted, and is deleted when the product is no longer generated by the corresponding material used. In this example, the updated new manufacturing code and the previous manufacturing code before the update are included in the manufacturer production management information.

  When the manufacturing code is updated, a new product chart for the corresponding product is created and stored in the product master DB 21. This product chart includes a newly added product chart code. The product chart including the product chart code associated with the previous production code and the product chart including the product chart code associated with the new production code are used for, for example, products (e.g. side dish such as croquettes, canned foods, etc.) The material and the history information of the material are different. Note that the product chart including the product chart code associated with the previous manufacturing code is stored in the product master DB 21 without being deleted until a product is not generated depending on the corresponding material used.

  Then, when the manufacturing code is updated, this is notified to the retail store servers 31 to 3N, and the manufacturing code in the POS information is updated. In this example, since the product names are the same (for example, as the product, XX croquette, xx canned food, etc. do not change), the in-store code is not updated in the retail store servers 31 to 3N.

  FIG. 6 is a flowchart illustrating an example of code management information update processing executed by the code management server 10 in the code management system 100 of the present example. The code management information update process is executed, for example, when instructed by an operator of the code management server 10 or periodically (for example, once a day early in the morning or late at night).

  In the code management information update processing, first, the code management server 10 includes the manufacturer production management in which the manufacturing code has been updated (updated since the last update) in the manufacturer production management information stored in the manufacturer production management DB 12. Information is read (step S201). Whether or not the manufacturing code has been updated is determined by whether or not the previous manufacturing code is included in the manufacturer production management information. After reading out the manufacturer production management information whose manufacturing code has been updated, the code management server 10 determines that the manufacturer production management information stored in the manufacturer production management DB 12 includes the previous manufacturing code. Delete the previous production code.

  Next, the code management server 10 searches the code management information including the previous manufacturing code acquired in step S201, and updates the manufacturing code in the searched code management information to the new manufacturing code. It is generated separately from the included code management information (step S202). That is, the code management information in which the manufacturing code is updated to the new manufacturing code is generated separately while the code management information including the previous manufacturing code remains.

  Then, the code management server 10 registers the use start date (the start period of the application period) of the production code in the use period item corresponding to the new production code (step S203). The application period information indicating the start of the application period is associated with the manufacturer production management information acquired in step S201, for example, and is read in step S201. For example, when the code management information is updated every day, a predetermined date (the current day, the next day, etc.) is the start of the application period.

  Furthermore, if the code management server 10 has received a use code end notification from the manufacturer's server, the use end date of the manufacture code (the end of the applicable period) is added to the use period item corresponding to the corresponding manufacture code. Is registered (step S204).

  FIG. 7 is a flowchart illustrating an example of a product search process executed by the code management server 10 in the code management system 100 of the present example. Here, a case will be described as an example in which product information such as materials used when the instore code specified by the operator of the retail store server 31 is assigned is retrieved.

  In the product search process, the code management server 10 receives an in-store code (for example, A00000023) from the retail store server 31 via the communication network 40 (step S301). Further, the code management server 10 receives a search target date (for example, October 15, 2006) input by the operator by operating the input device provided therein (step S302).

  Next, the code management server 10 refers to the code management DB 11 and associates code management information associated with the in-store code received in step S301 and including the date received in step S302 during the application period. Search and extract (step S303).

  Next, the code management server 10 selects the manufacturing code included in the code management information extracted in step S303, so that the product for which the in-store code received in step S301 is used is used in step S302. The manufacturing code used on the received date is specified (step S304). Here, two of the manufacturing code “000123” and the manufacturing code “000125” are specified.

  Next, the code management server 10 presents the production code specified in step S304 to the product master server 20, and the product chart code associated with the production code presented from the product master server 20 is given. The merchandise medical record that is stored is acquired (step S305).

  Then, the code management server 10 generates search result screen information for displaying a search result screen provided with a display area for product search result information including the product name and used material indicated by the acquired product chart, It transmits to the server 31 (step S306). The retail store server 31 displays the search result screen indicated by the received search result screen information on the display screen of the display device provided in itself. For example, as shown in FIG. 8, the search result screen includes a search condition display area 201 for displaying search conditions and a search result display area 202 for displaying search results.

  FIG. 8 shows an example of a search result when the in-store code “A0000025” and the date “October 15, 2006” are designated as the search conditions. As shown in FIG. 8, as a search result, the product indicated by the in-store code “A00000023” is the product name “canned A”, and on the designated date “October 15”, the manufacturing code “000123” and the product chart The code “KA00045”, the production code “000125”, and the product chart code “KA00048” are used, and the material used for the “canned A” is “Taraba rice cake” or “ It is indicated that the product with the production code “000125” was “taraba rice cake”, “seasoning γ”, and the like. At the time of the search (day), the product with the in-store code “A00000023” is given the production code “000123” or the production code “000125” (see FIG. 2), so the designated date “October 2006” The material used for the merchandise may be different from “15 days”. In this example, even if the manufacturing code (commodity chart code) is updated without updating the in-store code, it is possible to search for the material used for the corresponding commodity on the specified date.

  Further, when the code management server 10 receives the material selection information indicating the material selected by the operator on the search result screen of FIG. 8 from the retail store server 31, the code management server 10 applies the material usage history information indicated by the received material selection information. The search result screen information for displaying the search result screen provided with the display area for the extracted used material history information is generated from the product chart and transmitted to the retail store server 31 (step S307). The retail store server 31 displays the search result screen indicated by the received search result screen information on the display screen of the display device provided in itself. For example, as shown in FIG. 9, the search result screen includes a search condition display area 201 for displaying search conditions, a search result display area 202 for displaying search results, and a used material history display area for displaying used material history information. 203.

  FIG. 9 shows an example of a search result in the case where the material “Taraba rice cake” in the product with the production code “000123” is selected on the screen of FIG. As shown in FIG. 9, as a search result, in addition to the information shown in FIG. 8, production history information and distribution history information of the material “Taraba rice cake” used for the product “canned food A” on the designated date. It is shown. From this search result, the material used for the trade name “canned food A” and the history information of the material can be confirmed.

  In the above example, the date is accepted in step S302. However, the search target date range may be accepted. In this case, the code management server 10 refers to the code management DB 11 and is associated with the in-store code received in step S301 and includes the date range received in step S302 during the application period. May be retrieved and extracted.

  In the above example, a part of the product chart is extracted and displayed on the search result screen. However, the entire contents of the product chart may be extracted and displayed on the search result screen. In the above example, the search result screen is displayed. However, the search result screen may be printed, or the search result may be output by voice.

  As described above, in the above-described embodiment, each time the code management server 10 is given to a product when the product is produced or manufactured and the used material is updated, the used material is updated. Product identification code (manufacturing code, product chart code) that is given to subsequent products separately from the product before updating the materials used, and materials used after each product is given to the product indicated by the product identification code in each retail chain A code management DB 11 that stores code management information including in-store codes that are not updated depending on the update of the code, accepts designation of the in-store code given to the search target product, and codes the code management information including the received in-store code Search with reference to the management DB 11, specify the product identification code included in the searched code management information, specify The product identification code is used to obtain the product chart of the product to which the product identification code is assigned, and the product information indicated by the acquired product chart is output. Information of each product indicated by the in-store code that is separately assigned and used can be confirmed accurately. That is, when the product identification code (manufacturing code, product chart code) is updated by updating the material used for the product, the information of each product indicated by the in-store code that is not updated by the update of the material used for the product is accurately Confirmation (when only one item information is searched) or narrowing down (when only two or more items information is searched) can be performed.

  In the above-described embodiment, the code management server 10 accepts designation of the date to be searched, and among the in-store codes accepted from the retail store server 31, the application period including the date accepted from the retail store server 31 is associated. Since the code management information including the stored in-store code is searched, the product information of the product indicated by the corresponding in-store code can be searched on the specified date. Specifically, for example, it can be easily confirmed that “the product A indicated by the in-store code was produced using the materials A, B, and C on the designated day”.

  In the above-described embodiment, the code management server 10 acquires manufacturer management information including a product identification code given to the product by the manufacturer that manufactured or manufactured the product, and the acquired manufacturer management information is stored in the code management DB 11. Therefore, when a new product identification code is assigned, the new product identification code and product name can be registered in the code management DB 11.

  In the embodiment described above, the code management server 10 includes the in-store code and the product identification code of the product to which the in-store code is assigned from each retail chain server 31 to 3N managed in each retail chain. Since the retail store information is acquired and the acquired in-store code is registered in association with the acquired product identification code among the product identification codes registered in the code management DB 11, a new installation is performed in each retail chain. When an accord is given, the in-store code can be registered in the code management DB 11 as code management information in which a retail chain name or the like is associated with an appropriate product identification code.

  In the above-described embodiment, when the code management server 10 updates the use material of the product and separately assigns a product identification code, the code identification server 10 Acquires the manufacturer management information including the product identification code assigned to the product after updating the material used, and the product identification code assigned to the product before the use material update included in the acquired manufacturer management information In addition to the code management information that contains the product identification code assigned to the product before the update of the material used, the product assigned to the product after the update of the material used included in the acquired manufacturer management information Since the code management information updated to the identification code is generated and registered in the code management DB 11, when the product identification code is updated for a certain product, the product identifier before the update is updated. While leaving the code management information including a code, it is possible to register the code management information including the updated product identification code to code management DB 11.

  Further, in the above-described embodiment, the code management server 10 receives the selection of the material used included in the product information output (output as search result display screen information) to the retail chain server 31, and the received use Since the history information of the material is searched and the searched history information is output (output as search result display screen information), the history information of the material used for a certain product can be easily searched and presented.

  In the above-described embodiment, the in-store code is used. However, the code management information is a figure that is given to the product indicated by the product identification code in each retail chain instead of the in-store code or together with the in-store code. The code may be included. That is, a graphic code that is used privately in each retail chain may be used instead of or together with the in-store code.
