Description

  The present invention relates to a technique for grasping the location of a product (particularly, sold) using an information processing technique. Among them, in particular, as a grasp, it relates to a technique for determining or estimating the location or location information of the product.

  In recent years, product recalls have frequently occurred. When a manufacturer finds a defect in its product, it needs to be collected, but because it does not know the location of the product after it reaches the consumer's hand, it uses advertisements such as newspapers. You have to rely on the approach from consumers who own the product, such as working on an unspecified number of people. Therefore, the handling cost becomes enormous, but there is a problem that the recovery rate is bad.

  Against such a background, Patent Document 1 captures the problem that a mechanism for efficiently grasping the location of a product after it reaches the consumer's hand, and collects the user's personal information, A method for registering and managing possession information is disclosed. In other words, there is an possession database that registers and manages the user's personal information and possession information, and the user can register possession information of their possession, batch change, transfer ownership, and recall from the manufacturer You can receive notification of important product information.

  However, when the user moves, the user must distinguish the product that is not moved to the new address and the product that is moved, and register the change of owner information (location) for the moved product. It takes time and effort.

  Therefore, an object of the present invention is to make it possible to specify a hint for grasping the location or the location even if the location of the product (the product itself and the product information management source) is changed due to moving or the like. The purpose is that.

  In the present invention, the presence / absence of disposal and location information are calculated using product information (for example, product traceability data and update history of member information held by each trader). For example, as the update history, the probability of disposal is determined based on whether the latest storage (update) was performed within a predetermined period, and the existing probability calculated according to the movement attribute and update status determined for each product From the location information (information relating to the location of the product / product information), the disposal attribute determined for each product, and the disposal probability calculated according to the update status, the possibility of being discarded is calculated. In particular, location information includes using the location of the product, contact information such as the address of the product owner (may differ from the location of the product) and the service area of each location (sales shop or repair shop). It is.

  More specifically, the following embodiments are also included in the present invention.

  The member information DB 270 is a database for managing personal information such as an address of a member using a store in a retailer. The record field includes at least a member number 270a, member information update date / time 270b, a base ID 270c, an address 270d, and a name 270e.

  The membership number assigned to each member by the retailer is set in the membership number 270a.

  In the member information update date / time 270b, the date / time when the member information is registered / updated in the member information DB is set.

  In the base ID 270c, a base ID that uniquely specifies the base where the member information is registered / updated is set. For example, an ID (r200) that uniquely identifies a retailer, an ID that uniquely identifies a retailer's store, and the like are set.

  Address information is set in the address 270d among the personal information provided by the consumer. In the name 270e, name information among personal information provided by the consumer is set.

  Next, FIG. 4 is a configuration diagram of the storage device 303, which includes at least a traceability data management program 310 and an information providing program 330 as programs, and at least a traceability DB 360 as data.

  The traceability data management program 310 registers the traceability data generated by reading the tag 600 attached to the product with a reader in the waste disposal contractor in the traceability DB 360 or refers to the registered traceability data (search) ) Program.

  The information providing program 330 receives a request for a business history related to disposal from the product location grasping device 400 by the waste disposal contractor, extracts the corresponding data via the traceability data management program 310, and generates a list. And it is a program for responding to it. The flow of information providing processing executed by the information providing program 330 is the same as the processing flow of the information providing program 130 shown in the description of FIG.

  The traceability DB 360 is a database for managing or storing traceability data generated by a waste disposal contractor by reading a tag 600 attached to a product with a reader.

  In the product code 360b, a product code that uniquely specifies the type of product specified by the individual product ID 360a is set. In the case of a configuration in which the product code is included in the individual product ID, the field of the product code 360b can be omitted. In the case of the configuration, the product code is obtained by cutting out from the individual product ID set in the field of the individual product ID 360a. Further, a configuration in which the correspondence relationship between the individual product ID and the product code is managed by a separate table other than the traceability DB 360 and the field of the product code 360b is omitted from the traceability DB 360 is also conceivable. In the case of the configuration, the product code is obtained by reading from the separate table. When setting the product code 360b, it may be necessary to convert the individual product ID 360a to the product code. In that case, the problem can be solved by using a separate table for managing the correspondence between the individual product ID and the product code.

  “-” Is set in the member number 360c. However, if you maintain a separate database for member information and manage member numbers, set that value.

  In the base ID 360d, a base ID that uniquely specifies the base where the traceability data is generated is set. For example, an ID (w300) that uniquely identifies a waste disposal contractor, an ID that uniquely identifies a factory of the waste disposal contractor, and the like are set.

  The date and time 360e is set to the date and time when the traceability data is generated.

  In the work type 360f, the work name for which the traceability data is generated is set. For example, “discard” is set for traceability data generated in the discarding operation.

  The base ID 480b indicates the base where the member information is registered / updated in the information processing apparatus 100 and the information processing apparatus 200.

  Next, FIG. 10 is a flowchart of the product location request process and the product location grasp process. According to the flow, the product location request program 140 performs the product location request process, and the product location grasp program 410 performs the product location grasp process. Do. Specifically, the product location grasping program 410 receives a request for location information of a product from the product location request program 140, and the information processing device 100, the information processing device 200, and the information processing device 300 are Requests the business history associated with the product and the user, the business history related to the disposal, the update history of the information related to the user, and determines the location of the product based on the acquired information, or the location of the product in the product location estimation program 420 An estimation result is requested, an estimation result is obtained, and the above result is provided to the product location request program 140.

  First, the flow is started when the product location request program 140 transmits an individual product ID to the product location grasping program 410 (S1401). In the following description, the case where the individual product ID is “001” (the individual product is not discarded) and “002” (the individual product is discarded) will be described as an example.

  When the flow is started, the product location grasping program 410 receives the individual product ID (S4101), the business history associated with the product and the user, the consumer related history that is the business history related to the disposal, and the user In order to request a member information update history, which is an update history of information on the information, the individual product ID is notified to the information providing program 130, the information providing program 230, and the information providing program 330 (S4102), and the result is received (S4102). S4103). As to which information providing program 130, information providing program 230, and information providing program 330 should be issued in step S4102, for example, the access destinations of all information processing apparatuses are registered and managed in advance. This can be realized by issuing a request to the access destination. In the consumer-related history received in step S4103, the member number field is deleted in the information providing program 130, the information providing program 230, and the information providing program 330. Similarly, in the member information update history received in step S4103, the member number, address, and name fields are deleted in the information providing program 130, the information providing program 230, and the information providing program 330. As described above, it is possible to prevent the risk that a supplier who has requested the consumer-related history and the member information update history leaks the user's personal information to the product location grasping device 400, and thus the manufacturer's information processing device 100. The processing performed by the information providing program 130, the information providing program 230, and the information providing program 330 here will be described in the description of FIG. When the individual product ID transmitted in step S1401 is “001”, the content of the consumer related history received in step S4103 is a combination of (individual product ID, product code, base ID, date and time, work type). Derived from the traceability DB 160 (001, 100001, m100, 2007/04/10 10:00:30, user registration), derived from the traceability DB 260 (001, 100001, r200, 2007/04/01 15:00:30, Sales), (001, 100001, r200, 2007/10/05 10:20:30, repair reception) in total, the contents of the member information update history received in step S4103 are (member information update date, (Base ID) is derived from the member information DB 170 (2007/04/10 10:00:30, m100), derived from the member information DB 270 (2007/04/01 15:00:30, r200), (2007 / 10/01 13:21:20, r200), (2007/12/26 14:00:00, r200), (2013/04/01 15:00:00, r200), (201 8/05/04 12:00:00, r200), a total of 6 records. In addition, when the individual product ID is “002”, the content of the consumer-related history received in step S4103 is derived from the traceability DB 160 with a combination of (individual product ID, product code, site ID, date / time, work type). Yes (002, 100002, m100, 2007/05/15 12:20:10, user registration), (002, 100002, m100, 2007/09/17 10:40:10, user registration), derived from the traceability DB 260 (002, 100002, r200, 2007/05/05 17:35:30, sales), derived from the traceability DB 360 (002, 100002, w300, 2007/03/17 10:40:10, discarded), total 4 records The content of the member information update history received in step S4103 is that the combination of (member information update date and time, base ID) is derived from the member information DB 170 (2007/05/15 12:20:10, m100), 2007/09/17 10:40:10, m100), derived from the member information DB 270 (2007/05/05 17:35:30, r200) A total of 3, which is a record.

  Then, the product location grasping program 410 merges the consumer related history (individual product ID, product code, base ID, date and time, work type) into the consumer related history 470 which is a table on the memory, that is, each value is stored. Each column (individual product ID 470a, product code 470b, base ID 470c, date 470d, work type 470e) is set (S4104).

  Then, the product location grasping program 410 merges the member information update history (member information update date and time, base ID) into the member information update history 480 which is a table on the memory, that is, each value is stored in each column (member information update date and time). 480a, base ID 480b) (S4105).

  Then, the product location grasping program 410 checks whether there is a “discard” item in the work type 470e of the consumer related history 470, and if it exists, the process proceeds to step S4107, and if not, the process proceeds to step S4108. (S4106). When the individual item ID transmitted in step S1401 is “001”, since there is no “discarded” work type 470e in the consumer related history 470 of FIG. 6, the process proceeds to step S4108, and the individual item ID is If it is “002”, since there is “discard” in the work type 470e of the consumer related history 470 in FIG. 7, the process advances to step S4107.

  In step S4107, the product location grasping program 410 transmits to the product location request program 140 the individual product ID notified in step S4101 and the fact that the product has been discarded.

  The product location request program 140 receives the message and interprets that the product corresponding to the individual product ID notified in step S1401 does not exist (S1402). That is, information indicating that it does not exist or has been discarded is stored in the corresponding record.

  On the other hand, in step S4108, the product location grasping program 410 extracts the latest record of the consumer related history 470 (record with the latest date and time 470d) (S4108). When the individual item ID transmitted in step S1401 is “001”, the combination of (individual item ID 470a, product code 470b, base ID 470c, date 470d, work type 470e) in FIG. 6 is (001, 100001, r200, 2007/10/05 10:20:30, repair record) is extracted.

  Then, the product location grasping program 410, from the member information update history 480, among the records having the same base ID 470c as the base ID 470c of the latest record acquired in step S4108, the member information update date and time 480a is the date and time of the latest record acquired in step S4108. The member information update history (hereinafter, estimated start member information update history) of the nearest record before 470d is specified (S4109). When the individual product ID transmitted in step S1401 is “001”, the combination of (member information update date / time 480a, base ID 480b) in FIG. 8 is (2007/10/01) as the corresponding estimated start member information update history. 13:21:20, r200) record is specified.

  Then, the product location grasping program 410 confirms whether there is a record in the member information update history 480 that has a member information update date and time 480a later than that of the estimated start member information update history specified in step S4109. The process moves to step S4111, and if it exists, the process moves to step S4112 (S4110). When the individual product ID transmitted in step S1401 is “001”, since there is a record whose member information update date and time 480a is after “2007/10/01 13:21:20”, the process proceeds to step S4112.

  In step S4111, the product location grasping program 410 identifies the product location request program 140 in step S4109 as information including the individual product ID notified in step S4101 and the location of the product corresponding to the individual product ID. The estimated start member information update history is transmitted.

  The product location request program 140 receives the message. As a result, it is possible to identify the location of the product corresponding to the individual item ID notified in step S1401 via the supplier corresponding to the base ID of the estimated start member information update history included in the message (S1403). .

  On the other hand, in step S4112, the product location grasping program 410 obtains a record in which the member information update date and time 480a of the member information update history 480 existed in step S4110 is later than that of the estimated start member information update history specified in step S4109. Then, the estimated start member information update history acquired in step S4109 is merged. The result of merging here is the update history of the estimation target member information. When the individual product ID transmitted in step S1401 is “001”, the estimation target member information update history has a combination of (member information update date / time 480a, base ID 480b) in FIG. 8 (2007/10/01 13: 21:20, r200), (2007/12/26 14:00:00, r200), (2013/04/01 15:00:00, r200), (2018/05/04 12:00:00, r200 ) Record.

  Then, the product location grasping program 410 acquires the product code 470b and the date / time 470d of the record whose work type 470e is “sales” from the consumer related history 470 (S4113). Hereinafter, this date and time will be referred to as sales date and time. When the individual product ID transmitted in step S1401 is “001”, the product code 470b acquired from the consumer related history 470 in FIG. 6 is “100001”, and the date and time 470e is “2007/04/01 15:00. : 30 ”.

  Further, in step S4113 described above, there is a record in which the work type 470e is “sales” in the consumer related history 470. However, since the business history related to “sales” cannot be acquired from the retailer in step S4103, the consumer related If it does not exist in the history 470, it is determined that the record with the oldest date and time 470d among the records of the consumer related history 470 is a “sales” record.

  Then, the product location grasping program 410 notifies the product location estimation program 420 of the estimation target member information update history created in step S4112, the product code acquired in step S4113, and the sales date and time, so that the product is located. An estimation of a possible location is requested (S4114), and the result is received (S4115). When the individual product ID transmitted in step S1401 is “001”, the content transmitted in step S4114 is the combination of (member information update date, base ID) in the estimation target member information update history (2007/10 / 01 13:21:20, r200), (2007/12/26 14:00:00, r200), (2013/04/01 15:00:00, r200), (2018/05/04 12:00 : 00, r200), the product code is “100001”, the sales date is “2007/04/01 15:00:30”, and the content received in step S4115 is a discard probability of “51%”, ( (2007/10/01 13:21:20, r200, 9.8%), (2007/12/26 14:00:00, r200, 7.84%) (2013/04/01 15:00:00, r200, 6.272%), (2018/05/04 12:00:00, r200, 25.088%). Here, the processing performed by the product location estimation program 420 is described in the description of FIG.

  Then, the product location grasping program 410 receives the individual product ID notified in step S4101, the discard probability received in step S4115 with respect to the product location request program 140, and (member information update date, site ID, existence probability). Are transmitted as the location estimation result of the product corresponding to the individual product ID (S4116).

  The product location request program 140 receives the message, and the possibility exists that the product corresponding to the individual product ID notified in step S1401 is discarded (corresponding to the discard probability in step S4116). The location probability (corresponding to the presence probability in step S4116) of each location, the location ID of the vendor having the information on each location (corresponding to the location ID in step S4116), and the member information DB of the vendor, the location Based on the member information update date and time (corresponding to the member information update date and time of step S4116) to identify the existing information (that is, registration of information to that effect), or through a supplier corresponding to the base ID, As information processing for connecting to the location identification of the product corresponding to the individual product ID notified in step S1401. To identify the information (S1404).

  In the description of the flow of FIG. 10 described above, the product location request processing and the product location grasping processing when there is one individual product ID transmitted in step S1401 are described, but there are a plurality of individual product IDs notified in step S1401. The case is as follows. When the product location grasping program 410 receives a plurality of individual product IDs, it performs the following processing for each individual product ID. However, the processes in step S4107, step S4111, and step S4116 are listed when all the individual product IDs are processed, and transmitted to the product location request program 140.

  Next, FIG. 11 is a flowchart of information provision processing, traceability data management processing, and member information management processing. According to the flow, the information provision program 130 performs information provision processing, and the traceability data management program 110 performs traceability data management. The member information management program 120 performs member information management processing. Specifically, for the traceability data management program 110, the information providing program 130 provides a business history (member information presence history) associated with a product and a user and a business history (discard history) related to disposal for a certain product. Request / acquire and request / acquire the member information history to the member information management program 120 for the member number included in the member information existence history, and the user information is obtained from the member information existence history and the member information history. The fields related to the personal information are deleted, a consumer related history and a member information update history are created and transmitted to the product location grasping program 410.

  First, in the flow, the information providing program 130 is notified of the individual product ID from the product location grasping program 410, and the business history (member information existence history) associated with the user of the product corresponding to the individual product ID is as follows. It is triggered by receiving a request for a consumer-related history that is a discard history and a member information update history that is an update history of information related to the user (S1301). In the following description, the case where the individual product ID is “001” (the individual product is not discarded) and “002” (the individual product is discarded) will be described as an example.

  When the flow is started, the information providing program 130 requests a consumer-related history corresponding to the individual product ID from the traceability data management program 110 (S1302). That is, request information including an individual product ID is transmitted.

  The traceability data management program 110 receives the request (S1101), and records a record corresponding to the request, that is, a business history associated with a product such as “user registration” and “sales” and a business history related to disposal. Read from the traceability DB 160 (S1102). When the individual product ID transmitted in step S4102 is “001”, the content acquired here is a combination of (individual product ID 160a, product code 160b, member number 160c, base ID 160d, date 160e, work type 160f). Is one record of (001, 100001, 10011111, m100, 2007/04/10 10:00:30, user registration), and when the individual product ID is “002”, the content received here is ( The combination of the individual product ID 160a, product code 160b, member number 160c, site ID 160d, date 160e, work type 160f) is (002, 100002, 10011112, m100, 2007/05/15 12:20:10, user registration), ( 002, 10002, 10011112, m100, 2007/09/17 10:40:10, user registration).

  Then, the traceability data management program 110 transmits the record specified above to the information providing program 130 (S1103).

  The information providing program 130 receives the content (S1303), checks whether a history exists in the received message, moves to step S1309 if there is no history, and moves to step S1305 if there is a history. (S1304).

  In step S1305, the information providing program 130 checks whether there is a history of discarding the work type 160f in the history received in step S1303. If no history exists, the information providing program 130 moves to step S1306 and exists. In this case, the process proceeds to step S1309.

  In step S1306, the information providing program 130 acquires all the member numbers 160c from the history received in step S1303. When the individual product ID transmitted in step S4102 is “001”, “10011111” is acquired as the member number 460c.

  Then, the information providing program 130 requests the member information of the member number from the member information management program 120 (S1307). That is, request information including the acquired member number is transmitted.

  Upon receiving the request (S1201), the member information management program 120 reads a record corresponding to the member number included in the request from the member information DB 170 (S1202). When the individual product ID transmitted in step S4102 is “001”, the content acquired here is a combination of (member number 170a, member information update date 170b, base ID 170c, address 170d, name 170e) (10011111). , 2007/04/10 10:00:30, m100, Asa-ku, Kawasaki City, Kanagawa Prefecture ...

  When the member information management program 120 transmits the record specified above to the information providing program 130 (S1203), the information providing program 130 receives the content (S1308).

  In step S1309, the information providing program 130 deletes the field of the member number 160c from the business history (member information presence history) related to the user acquired in step S1303 and the business history related to disposal, and the consumer related history. The member information 170a, the address 170d, and the name 170e are deleted from the member information acquired in step S1308, and a member information update history is created and transmitted to the product location grasping program 410 (S1309). As described above, it is possible to prevent the risk that a supplier who has requested the consumer-related history and the member information update history leaks the user's personal information to the product location grasping device 400, and thus the manufacturer's information processing device 100. In addition, when the process of step S1304 is NO, information that there is no corresponding history is transmitted for both the consumer related history and the member information update history, and when the process of step S1308 is YES, the consumer related history is transmitted. . In this case, only the consumer-related history may be transmitted.

  Next, FIG. 12 is a flowchart of the product location estimation process and the product master management process. According to the flow, the product location estimation program 420 performs the product location estimation process, and the product master management program 430 performs the product master management process. Do. Specifically, the product location estimation program 420 gives the product master management program 430 a useful life of the product, a movement attribute indicating the ease of movement when the user moves such as moving, and a discard indicating the ease of disposal. Master information such as attributes is requested / acquired, and based on such information, the product discard probability and the existence probability of each place where the product may exist are calculated and transmitted to the product location grasping program 410.

  First, the product location estimation program 420 is notified of the estimated target member information update history, product code, sales date and time from the product location grasping program 410, so that the location of the product may be located. The process is started upon reception of an estimation request (S4201). In the following, a case where the individual item ID is “001” (the individual item is not discarded) will be described as an example.

  When the flow is started, the product location estimation program 420 requests the product master management program 430 for product master information of the product code (S4202).

  When receiving the request (S4301), the product master management program 430 reads a record corresponding to the product code from the product master DB 460 (S4302). When the product location grasping program 410 receives the product location estimation in step S4114 in step S4114 when the individual product ID received in step S4101 in FIG. 10 is “001” and the product location estimation program 420 requests it from the product master DB 460. The record is one record in which the combination of (product code 460a, product name 460b, useful life 460c, transfer attribute 460d, discard attribute 460e) is (100001, dryer A01 type, 5 years, 80%, 30%).

  Then, the product master management program 430 transmits the record to the product location estimation program 420 (S4303).

  Upon receiving the record (S4203), the product location estimation program 420 acquires (specifies) the useful life 460c from the received record (S4204). When the product location grasping program 410 receives the product location estimation in step S4114 for the product location estimation program 420 in step S4114 when the individual product ID received in step S4101 of FIG. 10 is “001”, the contents acquired here are: "5 years" is acquired as the service life 460c.

  Then, the product location estimation program 420 checks whether there is a record after the service life from the sales date and time acquired in step S4201 for the estimation target member information update history acquired in step S4201, and if present, the process proceeds to step S4206. If it does not exist, the process moves to step S4208 (S4205).

  In step S4206, the product location estimation program 420 acquires the discard attribute 460e from the product master received in step S4203. When the product location grasping program 410 receives the product location estimation in step S4114 for the product location estimation program 420 in step S4114 when the individual product ID received in step S4101 of FIG. 10 is “001”, the contents acquired here are: “30%” is acquired as the discard attribute 460e.

  In step S4207, since the member information has been updated from the sales date and time after the useful life and may have been discarded when moving such as moving, the product location estimation program 420 sets the value of the disposal attribute. And two or more estimation target member information update histories existing in step S4205 (hereinafter referred to as the service life elapsed member information update history. Note that the service life elapsed member information update history is sorted in ascending order by member information update date and time. Based on the above, the existing probability (existing probability) is calculated, the remaining probability is calculated as the probability of being discarded (discarding probability), and the process proceeds to step S4209. Specifically, first, in contrast to the disposal attribute, a non-disposition attribute that occurs after the useful life of the product and that may not be moved when moving, such as moving, is calculated. Is calculated as the non-discarded attribute, and the existing probability is calculated by raising the non-discarded attribute to the number of records in the lifetime member information update history, and the existing probability is subtracted from 1 This is the discard probability. When the product location grasping program 410 receives the product location estimation in step S4114 for the product location estimation program 420 in step S4114 when the individual product ID received in step S4101 in FIG. 10 is “001”, the discard attribute is 30%. Yes, since the number of records in the membership information update history is two, the non-discard attribute is (1-30%) and is “70%”, and the existing probability is the square of “49%” The discard probability is (1-49%), which is 51%.

  On the other hand, in step S4208, since the member information has not been updated after the end of the useful life from the date of sale, that is, there is no movement such as moving, the product location estimating program 420 The discard probability is set to “0%”, the existing probability is set to “100%”, and the process proceeds to step S4209.

  In step S4209, the product location estimation program 420 acquires the movement attribute 460d from the product master received in step S4203. When the product location grasping program 410 receives the product location estimation in step S4114 for the product location estimation program 420 in step S4114 when the individual product ID received in step S4101 of FIG. 10 is “001”, the contents acquired here are: Then, “80%” is acquired (specified) as the movement attribute 460d.

  Then, based on the value of the movement attribute, the product location grasping program 420 apportions the existing probability determined in step S4207 or step S4208 for each estimation target member information update history acquired in step S4201, and the product may be located. It is calculated as the existence probability for each characteristic place (S4210). Specifically, the existing probability acquired in step S4207 or step S4208 is calculated based on the value of the movement attribute for the first record of the estimation target member information update history, and from 100% for the second and subsequent records. The values are distributed at a ratio of the values, and these values are set as the existence probabilities corresponding to the first record and the second and subsequent records of the estimation target member information update history. When there is a third record in the estimation target member information update history, the existence probability corresponding to the second and subsequent records in the estimation target member information update history is calculated using the second record in the estimation target member information update history. Allocate the value of the movement attribute to the records, and the third and subsequent records at a ratio of 100% minus the value of the movement attribute, and then distribute these values to the second record of the estimated member information update history And the existence probability corresponding to the third and subsequent records. The above process is repeated until the existence probabilities corresponding to all the records of the estimation target member information update history are calculated, and the existence probabilities for each location corresponding to each record are calculated. When the product location grasping program 410 receives the product location estimation in step S4114 in step S4114 when the individual product ID received in step S4101 in FIG. 10 is “001” and the product location estimation program 420 requests the product location estimation program 420 in step S4114. Are the combinations of (member information update date, base ID) (2007/10/01 13:21:20, r200), (2007/12/26 14:00:00, r200), (2013/04/01 15:00:00, r200), (2018/05/04 12:00:00, r200), and the member information update date is updated to "2007/10/01 13:21:20" The corresponding presence probability is “9.8%”, which is 20% of the existing probability calculated in step S4207 (100-movement attribute), and the member information update date is updated to 2007/12/26 14:00:00 The presence probability corresponding to the registered member information is 20% (100-movement attribute) of 39.2%, which is 80% (movement attribute) of the existing probability calculated in step S4207. The existence probability corresponding to the member information whose member information update date is 2013/04/01 15:00:00 is 80% (movement attribute) of 39.2%. The existence of the location corresponding to the member information that was updated to "2018/05/04 12:00:00" with "6.272%", which is 20% (100-movement attribute) of a certain 31.36% The probability is “25.088%” which is 80% (movement attribute) of the 31.36%.

  Then, the product location grasping program 420 transmits the product location estimation result to the product location grasping program 410 (S4211).

  In the product location estimation process performed by the product location estimation program 420 of FIG. 12 described above, the discarding probability and the existing probability are obtained in step S4207 or step S4208, and further, the existing probability is acquired in step S4201. The probability of existence of each place where the product may be located was determined and the location corresponding to the estimation target member information update history in chronological order of the estimation target member information update history. It is also conceivable to perform an estimation process based on successively finding the probability of moving to, the probability of leaving without moving, that is, the probability of being discarded without moving. Specifically, when the second record of the estimation target member information update history has been updated after the useful life from the sales date, the estimation is performed at the date corresponding to the first record of the estimation target member information update history. The probability of being present at the location corresponding to the first record of the target member information update history is multiplied by the non-discard attribute that is obtained by subtracting the discard attribute from 1. By multiplying the value by the non-moving attribute obtained by subtracting the moving attribute from 1, the probability of existing at the location corresponding to the first record of the estimated target member information update history is obtained, and the estimated target member information is multiplied by the moving attribute The probability of being present at the location corresponding to the second record of the update history of the estimation target member information at the date and time corresponding to the second record of the update history. On the other hand, if the second record of the estimated target member information update history is updated before the service life from the sales date and time, the estimated target member information at the date and time corresponding to the first record of the estimated target member information update history The first record of the estimated target member information update history is currently multiplied by the non-moving attribute obtained by subtracting the moving attribute from 1 for the probability of being present at the location corresponding to the first record of the updating history. The probability of existing in the location corresponding to the second target of the estimated target member information update history at the date and time corresponding to the second record of the target target information update history multiplied by the movement attribute And By repeating the above process until all records for the estimation target member information update history are completed, the existence probability for each location corresponding to each record is calculated.

  Although the best mode for carrying out the present invention has been specifically described above, the present invention is not limited to this, and various modifications can be made without departing from the scope of the invention.

  For example, in step S1401 of FIG. 10, the product location request program 140 requests the product location grasping program 410 for the location of the product corresponding to the specified individual product ID. In step S4102, the individual product ID is supplied to the information providing program 130. The business history associated with the product and the user and the business history related to the disposal are requested, and the result is received in step S4103. In step S1401, the product location requesting program 140 receives the product location grasping program. For 410, a product code may be designated and the location of all products corresponding to the product code may be requested. In that case, the product code is notified to the information providing program 130 or the like in step S4102, and the business history associated with the product and the user and the business history related to disposal are requested for all products corresponding to the product code. In step S4103, the result is received, and the processing in step S4104 and subsequent steps is performed for each individual product. At this time, with respect to the discard history and member information presence history received in step S1303 of FIG. 11, the subsequent processing is performed for each individual product ID history, and in step S1309, consumer related history and member information update are performed for each individual product ID. The items associated with the history are collectively transmitted to the product location grasping program 410.

  In the best mode for carrying out the present invention, in step S1309 in FIG. 11, the member number 160c is obtained from the job history (member information presence history) related to the user acquired in step S1303 and the job history related to discard. Field (for example, only this feed) was deleted to create a consumer-related history, but in reality, each vendor tends to hesitate to publish the business content related to the product. Therefore, in addition to the deletion of the member number 160c field, “discard” is described only when the field of the work type 160f is “discard”, and the other is converted to “−” and the consumer related history 470 is converted. May be created. In this case, in step S4113 in FIG. 10, there is no record in which the work type 470e is “sales” in the consumer related history 470. Therefore, among the records in the consumer related history 470, the oldest date and time 470d is “ It is regarded as a “sales” record. That is, the item “sales” is added to the record.

  In the best mode for carrying out the present invention, in the product location estimation process performed by the product location estimation program 420 of FIG. 12, the location estimation process is performed based on the values of the movement attribute 460d and the discard attribute 460e of the product master 460. However, there are cases where the location estimation process is performed based on the information provided by the repairer, such as the number of repairs of the product and the details of the repair. For example, when the product location grasping device 400 receives traceability data of the product from the repairer, and thus information on the number of repairs and details of repairs, the product location storing device 400 stores in advance the number of repairs in the value of the discard attribute 460e acquired in step S4206 in FIG. By adding a value obtained by multiplying a constant value (for example, 5) stored in the device 103, a new value of the disposal attribute is set, and thereafter, the location estimation process of the product is performed using the value. .

  In the best mode for carrying out the present invention, the disposal attribute and the movement attribute are set with constant values and the product location estimation process is performed. However, the disposal attribute and the movement attribute are set with a function, and the location estimation process is performed. May be performed. For example, when the discard attribute is set by a linear function with the number of days used as a variable, the slope and intercept of the linear function are set in the discard attribute 460e of the product master DB 460. Then, for each record of the service life elapsed member information update history, the difference between the date and time and the sales date and time acquired in step S4201 is taken to determine the number of days used corresponding to each record, and the value is multiplied by the slope of the linear function, By adding the intercept, it is possible to calculate the value of the discard attribute of each record of the service life member information update history.

  Further, in the best mode for carrying out the present invention, in the product location estimation process performed by the product location estimation program 420 of FIG. 12 so that the discard probability is 0% before the useful life, the service life elapsed member information is obtained. Although the discard probability was calculated only for the update history, in reality, it may be discarded even before the useful life, so the discard probability may be calculated for all the update history of member information to be estimated is there.

  In the best mode for carrying out the present invention, the transfer attribute 460d and the discard attribute 460e of the product master DB 460 of FIG. 5 are given by constant values, and the discard probability is calculated only for the service life elapsed member information update history. In this way, the location estimation process of the product is performed, but by using the consumer related history 470 and the member information update history 480, it is also possible to calculate the movement attribute and the disposal attribute from the actual record each time it is estimated. Specifically, for each record of the consumer related history 470, from the member information update history 480 of the same base 480b as the base ID 470b, the member information update date 480a is the closest before the date 470d of the record of the consumer related history 470. If there are one or more sets of records with the same base ID 480b, the product has moved one or more times. Therefore, a value obtained by dividing the total number of products by the total number of products is used as the movement attribute. In addition, since the difference in date and time when the work type f of the consumer related history 470 of FIG. 7 is “sales” and “discard”, the number of use days until a product with a certain product ID is discarded is obtained. It is possible to obtain a graph of disposal attributes using the number of days and the value obtained by dividing the number of discarded products for each number of used days by the total number of discarded products.
