Description

  The present invention relates to a product purchase appropriate time information distribution system, a product purchase appropriate time information providing server, a product purchase appropriate time information distribution method, a product purchase appropriate time information distribution program, and a program recording medium.

  As a conventional technology for providing information to customers, the conventional point-of-sales (POS) system accumulates and analyzes only the sales results of products, sales trends by product group or similar product groups, and sales trends by season Analyzing information with the product or similar product group as the primary key, etc., or by issuing a membership number with a membership card in addition to the sales results of the product, the customer personal information is accumulated, one rank advanced information In general, analysis (for example, analysis of sales trends by gender, sales trends by age group, etc.) is used for sales expansion activities.

  However, even in the latter type of POS system in which personal information of customers is stored, the information storage and analysis unit is limited to individual customers. For example, in Japanese Patent Application Laid-Open No. 2001-325523, “Product recommendation system, product recommendation method, recording medium, product sales system, product sales method” of Japanese Patent Application Laid-Open No. 2001-325523, information on a purchase appropriate time for a user to purchase a product Has a function to notify. However, it is a dealer-centered system, and it is impossible for each user to obtain information regarding the appropriate purchase date for a certain product at an arbitrary opportunity. It was not a countermeasure for use. For this reason, even if someone in the same group has purchased a product of the same product group, it will provide information on the appropriate purchase period for the product of the same product group to the user of the group. In some cases, products in the same product group are purchased redundantly, and the user is not provided with an appropriate purchase period for the product.

JP 2001-325523 A (pages 7-8)

  In other words, in the conventional POS system of the type that accumulates customer personal information, it is only a store-based one, and the unit of information accumulation and analysis is not the group to which the customer belongs, The customer stayed alone.

  In particular, in the case of commodities such as consumables (for example, general household consumables and general office supplies), they belong to a specific group (for example, family, household, circle, etc.). It is assumed that a situation where a plurality of users commonly use products that are commonly used or purchased separately and used separately is stocking the purchased products. In such a case, even if the conventional mechanism is used, for the store side that analyzes the sales trend of the product, there is a big fluctuation in the extraction of the sales trend by the information accumulation and analysis in the individual user unit. Therefore, there is a problem that the timing of sending advertisements and product information may be missed.

  Further, as described above, there is a problem that the customer side user may purchase the same product in duplicate within a specific customer group (family, household, circle, etc.). .

  The present invention has been made in order to solve such a problem. At any timing desired by the user, the present invention includes not only the user himself / herself but also each member of the group to which the user belongs. Product purchase timeline information distribution system, product purchase timeline information distribution server, product purchase timeline information distribution method, product, which can provide the user with information on the product attributes or the appropriate time for purchase for each product based on the purchase history It is an object of the present invention to provide a purchase appropriate time information distribution program and a program recording medium.

It is. The product attribute DB 129 can use an existing database as it is. The product identification information 129d is product identification code information indicated by a barcode attached to the product or the like.

(Description of operation of embodiment)
Next, an example of the operation of the commodity purchase appropriate time information distribution system 10 shown in FIG. 1 and FIG. 2 shown as an example of the present invention will be described using a flowchart.

  As shown in FIG. 1, a store server 111 and a POS register 112 are installed as the store facility 11, and they are interconnected. Further, it is assumed that the store server 111 is communicable with the product purchase appropriate time information providing server 12 installed at the store headquarters by communication means such as the Internet. In addition, in the product attribute DB 129, as shown in FIG. 2C, information (product attribute 129a, product category 129b, product name 129c, product related to products sold at each store where the store facility 11 is arranged). It is assumed that the identification information 129d and the like are classified by the product attribute 129a and are registered in advance for each product category 129b.

  First, the user (customer) member registration procedure performed as preparation for performing detailed management regarding the purchase timelines of goods (for example, consumables) for each user or for each group to which each user belongs is shown in FIG. It demonstrates using the flowchart of these. FIG. 3 is a flowchart for explaining an example of a procedure for registering a user as a member in the product purchase appropriate time information distribution system 10 shown in FIG. 1. When the member registration is completed, a member card is given to the user. An example of a procedure until it is issued is shown. In the flowchart of FIG. 3, when a user first uses a store where the store facility 11 is installed, the user applies for membership registration using an application form in a predetermined format (step S1).

  In the application form, in addition to personal information (address, name, gender, date of birth, age, contact information, etc.) related to the user, identification information that uniquely identifies a group attribute that is a feature of the present invention, Add to group attributes that have already been registered (for example, group identification information that has already been assigned to any user of the user's family) or new group attributes (for example, anyone whose family is still registered (Identification information of a group to be registered as a new group) is selected. Here, the identification information for uniquely identifying the group attribute is information for identifying the group to which the user belongs, and the group attribute 127b in the user information DB 127 in FIG. 2A and the purchase history in FIG. 2B. The group attribute 128b of the DB 128 exemplifies a case where a 4-digit number string is given as the identification information.

  The store clerk who has received the application form takes out one new membership card prepared in advance in the store (step S2). In the new member card, only identification information (that is, a member number) uniquely assigned at the store head office to which the store belongs is recorded in advance. As a new member registration operation from the console of the store server 111 by the store clerk of the store, the personal information described in the received application form and the member number information recorded on one member card previously taken out Is entered, the user's personal information and information regarding the membership number are transmitted from the store server 111 to the product purchase appropriate time information providing server 12 side (step S3).

  Upon receiving the user's personal information and information regarding the membership number from the store server 111 as new user information, the merchandise purchase appropriate time information providing server 12 receives the user related to the user information DB 127 from the customer management unit 121. Instructs registration of information. Upon receiving the registration instruction, the customer management unit 121 registers the user information included in the received registration instruction in the user information DB 127. In the user information DB 127 in FIG. 2A, only the member number 127a, the group attribute 127b, and the user name 127c are shown as user information, but other user information (address, Gender, date of birth, age, contact information, etc.) are also registered in the user information DB 127.

  At this time, it is confirmed whether there is no problem in the registration of the group attribute of the user (step S4). That is, when a group attribute is newly registered as a member registration application form by the user, it is checked whether or not the identification information indicating the group attribute input to be registered is not yet registered in the user information DB 127. Check that the same group attribute (group identification information) is not used twice. In addition, when adding to the already registered group attribute, it is checked whether or not the identification information indicating the registered group attribute is already registered in the user information DB 127, and the identification information indicating the group attribute is incorrect. Confirm that it is not entered.

  If there is no problem in group attribute registration (YES in step S4), the user information included in the registration instruction is registered in the user information DB 127 (step S5). When registration in the user information DB 127 is completed, the customer management unit 121 in the product purchase appropriate time information providing server 12 notifies the registration request source store server 111 of “registration complete” (step S6). On the other hand, when there is a problem in the registration of the group attribute (NO in step S4), that is, when the identification information indicating the group attribute that has been input when newly registering the group attribute has already been registered, or If the identification information indicating the group attribute is unregistered despite the addition to the already registered group attribute, the customer management unit 121 in the product purchase appropriate time information providing server 12 The “registration error” is notified to the store server 111 (step S8). When the “registration error” is returned to the store server 111, the store clerk requests the user to review the identification information regarding the group attribute, changes the identification information regarding the group attribute (step S9), and then returns to step S3. Then, the user information registration procedure is repeated again.

  Through the above procedure, when the registration of the user information in the user information DB 127 is completed successfully and “registration complete” is returned to the store server 111, the user member registration is completed, and the newly prepared member The card becomes a member card 113 dedicated to the user, and the member card 113 is handed over to the user (step S7).

  Next, when a user who has completed membership registration purchases a product at a store where the store facility 11 is installed, the purchase information related to the product purchased by the user is provided as a new purchase history record. The flow of additional registration in the purchase history DB 128 of the server 12 will be described using the flowchart of FIG. FIG. 4 is a flowchart for explaining an example of a state in which the recorded content of the purchase history DB 128 in the product purchase appropriate time information providing server 12 is updated in the product purchase appropriate time information distribution system 10 shown in FIG. It shows a state where a new purchase history record is additionally registered in the purchase history DB 128 in the product purchase appropriate time information providing server 12 every time a product is purchased at a store where the store equipment 11 is installed.

  When a user purchases a product at a store where the store equipment 11 is installed, the member card 113 carried by the user is scanned by means such as a card reader attached to the POS register 112 to obtain the member number of the user. At the same time (step S11), the product identification information (barcode) affixed to the purchased product is read by means such as a barcode reader attached to the POS register 112, and the POS register 112 generates settlement information and (Step S12). Further, the POS register 112 transmits a membership number and settlement information including product identification information to the store server 111. The store server 111 stores settlement information including a member number, product identification information, and the like from the POS register 112, and stores the membership number, product identification information, and purchase date as purchase record information in the product purchase appropriate time information providing server 12. Transmit (step S13).

  Upon receiving the purchase record information from the store server 111, the product purchase appropriate time information providing server 12 delivers the product identification information included in the purchase record information to the product management unit 122, and the product attribute corresponding to the product identification information Instructs the extraction of information. The product management unit 122 searches the product attribute DB 129 based on the delivered product identification information, extracts product attribute information (product attribute, product category, product name, etc.) corresponding to the product identification information, It returns (step S14).

  The product purchase appropriate time information provision server 12 takes over the extracted product attribute information, the membership number and purchase date included in the purchase record information to the customer management unit 121, and instructs the purchase history DB 128 to register the purchase record information. I do. Upon receiving the registration instruction, the customer management unit 121 searches the user information DB 127 based on the membership number included in the received registration instruction, and extracts a group attribute corresponding to the membership number (step S15). ).

  Further, the customer management unit 121 extracts the product name and / or product attribute from the product attribute information related to the purchased product inherited from the product management unit 122, and the member number included in the registration instruction and the extracted product name and / or Or, using two pieces of information on product attributes as keys, someone in the group to which the user with the member number belongs (someone in the group that includes the user) previously purchased the product with the product name and / or the product attribute. The purchase history DB 128 is searched so that the purchase history record is traced back from the new date to the old date. As a search result, with respect to the user of the member number or the group to which the user belongs, the last purchase date information on the purchase of the product with the product name and / or the product attribute in the past is acquired. The customer management unit 121 obtains the difference in the number of days between the acquired past purchase date in the past and the purchase date included in the received registration instruction, so that the product related to the user of the member number or the group to which the user belongs The purchase interval of the product with the name and / or the product attribute is calculated (step S16).

  After that, the customer management unit 121 receives the purchase history record including the membership number 128a, group attribute 128b, product attribute 128c, product name 128d, purchase date 128e, and purchase interval 128f as shown in FIG. The membership number included in the registration instruction, the group attribute extracted from the user information DB 127, the product attribute information (product attribute, product category, product name, etc.) notified from the product management unit 122, and the purchase obtained by calculation A new record including the interval is generated and registered in the purchase history DB 128 (step S17).

  As described above, the additional registration operation of a new purchase history record in the purchase history DB 128 is terminated. However, the additional registration operation of the purchase history record is repeated every time the user purchases a product, and the purchase history record in the purchase history DB 128 is stored. Are accumulated from time to time.

  Next, an operation example in the case where there is a distribution request for information related to the appropriate purchase period of the product from the user will be described using the flowchart of FIG. FIG. 5 is a flowchart for explaining an example of an operation for distributing information related to a product purchase time period from the product purchase time limit information providing server 12 to the user terminal 13 in the product purchase time limit information distribution system 10 shown in FIG. When a request for delivery of purchase timing information regarding a product from the user terminal 13 including the mobile terminal 132 (in this embodiment, a case where a consumable is designated as a product field) is generated, in response to the delivery request, An operation of distributing information related to the purchase appropriate time for the product group of each product attribute belonging to the product field “consumables” from the information distribution unit 126 of the product purchase appropriate time information providing server 12 to the requesting user terminal 13 is shown. FIG. 6 is a screen diagram showing an example of specific contents displayed on the screen of the user terminal 13 of the product purchase appropriate time information distribution system 10 shown in FIG. 1 as information on the purchase appropriate time as a “product purchase appropriate time list screen”. In this example, information on the appropriate purchase period of a product group having a product attribute belonging to the product field “consumables” is shown as an example.

  In the flowchart of FIG. 5, when a user inputs a distribution request for a list of items appropriate for purchase related to products and product fields such as consumables to the user terminal 13 such as the PC 131 and the portable terminal 132, the user terminal 13 can communicate with the communication means such as the Internet. Accordingly, a distribution request for the list information of the purchase appropriate time regarding the product and the product field, for example, consumables, instructed by the user is transmitted to the information distribution unit 126 of the product purchase appropriate time information providing server 12 (step S21).

  The information distribution unit 126 that has received the distribution request inquires of the requesting user terminal 13 whether the group attribute should be reflected. Upon receiving the inquiry, the user terminal 13 (PC 131 or portable terminal 132) displays an inquiry screen as to whether to reflect the group attribute on the screen and prompts the user to select. When an operation is performed to select whether or not to reflect the group attribute in the purchase time period related to the product or product field designated by the user, for example, consumables, the selection result is obtained from the information distribution unit of the inquiry source product purchase time period information providing server 12 126 is returned. Whether the group attribute is reflected or not is determined immediately by the user terminal 13 from the user terminal 13 when the user inputs a distribution request for a list of items suitable for purchase, such as consumables, to the user terminal 13. By making an inquiry and allowing the user to make a selection, when a distribution request is transmitted to the information distribution unit 126, the selection result regarding the group attribute may be transmitted in a format attached to the distribution request.

  The information distribution unit 126 that has received the selection result related to the group attribute refers to the selection result and determines whether or not the selection result reflects the group attribute (step S22).

  If the selection result reflects the group attribute (YES in step S22), the information distribution unit 126 sends the membership number attached to the distribution request from the requesting user to the customer management unit 121. , Request the return of each purchase history record regarding the group attribute of the group to which the user of the member number belongs.

  Upon receiving the return request, the customer management unit 121 first searches the user information DB 127 based on the sent membership number, extracts the group attribute of the group to which the user with the membership number belongs, and then Based on the extracted group attribute, the purchase history DB 128 is searched, a purchase history record related to the group attribute is extracted, and returned to the requesting information distribution unit 126 (step S23).

  On the other hand, if the selection result indicates that the group attribute is not reflected (NO in step S22), the information distribution unit 126 sends the membership number attached to the distribution request from the requesting user to the customer management unit 121. Send and request the return of each purchase history record for the user with that membership number.

  Upon receiving the return request, the customer management unit 121 searches the purchase history DB 128 based on the sent member number, extracts a purchase history record related to the member number, and returns it to the information distribution unit 126 of the request source. (Step S30).

  The information distribution unit 126 that has received the purchase history record from the customer management unit 121 in step S23 or step S30 is that the request from the user relates to the appropriate purchase period of the product group of the product attribute belonging to the product field, for example, consumables. In this case, the purchase history records returned from the customer management unit 121 are first sorted by product attribute (step S24).

  Thereafter, the purchase history records rearranged for each product attribute are sent to the group last purchase date calculation unit 125b to instruct the calculation of the last purchase date for each product attribute. The group last purchase date calculation unit 125b calculates the last purchase date for each product attribute by referring to the purchase date of the sent purchase history record (step S25). In other words, if the group attribute is reflected, the last purchase date for each product attribute in the group attribute of the group to which the user belongs is calculated. If the group attribute is not reflected, the last purchase for each product attribute for the user is calculated. Calculate the day.

  Next, the information distribution unit 126 confirms whether or not the calculated last purchase date for each product attribute is the latest date determined in advance, for example, today or yesterday (step S26). If there is a product with the product attribute (consumable item) that has the latest purchase date (YES in step S26), a request for distribution of list information on the product field, for example, expiring time for the consumable item is issued. Display indicating that the user who made the purchase or someone in the group to which the user belongs is purchasing the product on the most recent day (for example, “Recently purchased by Mr. and Mrs.” as indicated by reference numeral B6 in FIG. 6) Is added so as to be added to the product purchase appropriate time list screen (step S31).

  On the other hand, when each product (consumable item) having a certain product attribute is not the latest purchase date (NO in step S26), based on the purchase interval of each product belonging to the product attribute. The purchase interval of the product attribute in the past is calculated (step S27). For example, among the purchase intervals of each product set as purchase history records sorted by product attribute, the average purchase interval of each product belonging to the corresponding product attribute is calculated, and the purchase of the product attribute in the past is calculated. Interval. If the group attribute is not reflected, the purchase history record related to the user is extracted in step S30, but the purchase interval set in the purchase history record sorted for each product attribute is within the group. There may be a case where only the purchase interval is set and the purchase interval cannot be used. In such a case, after sorting by the purchase date of each product belonging to the corresponding product attribute, first the process of calculating the purchase interval of each product by calculating the difference from the purchase date of the previous product. Then, the purchase interval in the past of the product attribute is calculated by calculating the average of the purchase intervals of each product.

  Next, the information distribution unit 126 calculates the number of days from the last purchase date related to the product attribute calculated in step S25 to the present (today), and purchase of the product attribute in the past calculated in step S27. The number of days indicated by the interval is compared (step S28). When the calculated number of days to date has exceeded a predetermined number of days threshold n (for example, 7 days) compared to the number of days indicated by the purchase interval in the past of the product attribute (YES in step S28) Therefore, it is determined that the product with the product attribute has reached the appropriate time for purchase, and the product list of the product attribute is displayed (for example, the product category as shown by reference numeral B3 in FIG. 6 is “shampoo” and “shampoo”. Each product as shown in FIG. 6 that belongs to the product category is edited as a product purchase appropriate time list screen (step S29).

  On the other hand, the number of days from the last purchase date related to the product attribute to the present (today) is greater than or equal to a predetermined number of days threshold n (for example, 7 days) compared to the number of days indicated by the purchase interval of the product attribute in the past. If it has not elapsed (NO in step S28), it is determined that the product attribute has not yet reached the appropriate purchase date, and the process proceeds to a determination process relating to another product attribute. After that, when the processing of steps S28 and S29 is finished for all the product attributes, the information distribution unit 126 returns the edited product purchase appropriate time list screen to the requesting user terminal 13.

  The requesting user terminal 13 presents the returned merchandise purchase appropriate time list screen to the user by displaying it on the user terminal 13 (for example, the PC 131 or the portable terminal 132).
