A carry-in recording unit 130 that records the process carry-in date and time IDT of the target MMS, and a carry-out record unit that records the process carry-out date and time ODT of the production management target MMS for each production process MP for each target identification data SID received by the carry-out receiving unit 120 140, the process carry-in date / time IDT and the process carry-out date / time ODT recorded for each target identification data SID With a stock detector 150 for detecting the production managed MMS that was stock production MP in constant time, the.

  The object management system 1000 of this embodiment is used in an assembly factory as shown in FIG. 2, for example. In this case, the aforementioned production management target MMS is composed of assembly parts in an assembly factory.

  The carry-in position reader 210 and the carry-out position reader 220 are RFID readers. The carry-in position reader 210 is installed for each of the carry-in positions of the plurality of production processes MP in the assembly line of the assembly plant, and the carry-out position reader 220 is installed for each carry-out position.

  The carry-in position reader 210 and the carry-out position reader 220 are individually assigned carry-in identification data IID and carry-out identification data OID. Therefore, the carry-in position reader 210 and the carry-out position reader 220 transmit the target identification data SID acquired from the RFID tag 200 of the production management target MMS to the target management apparatus 100 together with its own carry-in identification data IID or carry-out identification data OID. To do.

  The target management apparatus 100 is composed of, for example, a database server installed in a backyard of an assembly factory. The target management apparatus 100 also has a management database 160, and this management database 160 stores target management data MSD in which target identification data SID is individually set for each production management target MMS.

  Although the target identification data SID is individually registered in the RFID tag 200, the production management target MMS is also set with classification identification data for each assembly part classification, type identification data for each type, and the like ( Not shown). For this reason, the correspondence relationship between the above-described classification identification data, type identification data, and the like and the target identification data SID is also registered in the management database 160 (not shown).

  Further, as described above, the carry-in position reader 210 and the carry-out position reader 220 are individually assigned carry-in identification data IID or carry-out identification data OID. For this reason, in the management database 160, the correspondence relationship between the carry-in identification data IID or the carry-out identification data OID and the carry-in / out position of the production process is also registered (not shown).

  The object management apparatus 100 also includes an inventory output unit 170 that outputs the in-process inventory quantity for each production process MP of the production management object MMS. The inventory output unit 170 displays a list of in-process inventory quantities of a plurality of production processes MP. Further, the inventory output unit 170 displays a list of in-process inventory quantities for each of a plurality of predetermined periods.

  Therefore, as shown in FIG. 4, the inventory output unit 170 displays an inventory transition graph STG in which one of the horizontal axis and the vertical axis is a plurality of predetermined periods and the other is an in-process inventory quantity of a plurality of production processes MP. Generate and display an image.

  The target management apparatus 100 logically implements the above-described units 110 to 170 by executing various processing operations in accordance with an appropriate computer program that is installed.

  For example, each of the receiving units 110 and 120 corresponds to a function in which the database server recognizes received data of a communication device (not shown) corresponding to a computer program. Each unit 130 to 150 corresponds to a function of the database server executing various data processing corresponding to the computer program.

  The management database 160 corresponds to a storage area of a storage device recognized corresponding to the computer program. The inventory output unit 170 corresponds to a function of displaying and outputting image data on a display device corresponding to a computer program.

  The computer program as described above includes, for example, a data management process for constructing a management database 160 for storing the target management data MSD in which the target identification data SID is individually set for each production management target MMS and the production process MP. Input and reception processing for receiving the target identification data SID acquired from the RFID tag 200 of the production management target MMS, and the target identification data SID acquired from the RFID tag 200 of the production management target MMS exported from the production process MP. Received carry-out receiving process, carry-in recording process for recording the process carry-in date / time IDT of the production management object MMS for each production process MP for each target identification data SID received in the carry-in receive process, and the object received in the carry-out receive process Process export of production management target MMS for each production process MP for each identification data SID Inventory for detecting the production management target MMS stocked in the production process MP at a specific date and time by the unloading recording process for recording the time ODT and the process loading date and time IDT and the process unloading date and time ODT recorded for each target identification data SID It is described that the target management apparatus 100 executes the detection process and the inventory display process for causing the display device to display and output the in-process inventory quantity for each production process MP of the production management target MMS.

  In the configuration as described above, a data processing method by the target management system 1000 of the present embodiment will be described below. As described above, in an assembly factory that uses the object management system 1000 of the present embodiment, assembly products that are sequentially assembled in a plurality of production processes MP are data-managed as production management objects MMS.

  Therefore, the RFID tag 200 is attached to the production management target MMS as a so-called electronic kanban. Since the target identification data SID is individually recorded in the RFID tag 200, the production management target MMS is data-managed by the target management apparatus 100 based on the target identification data SID.

  When the production management object MMS as described above moves in a plurality of production processes MP in sequence, the RFID tag 200 of the production management object MMS carried into the production process MP is detected by the carry-in position reader 210 and carried out from the production process MP. The RFID tag 200 of the production management target MMS to be detected is detected by the unloading position reader 220.

  The carry-in position reader 210 and the carry-out position reader 220 that have detected the RFID tag 200 as described above acquire the target identification data SID and transmit it to the target management apparatus 100 together with its own carry-in identification data IID or carry-out identification data OID.

  Then, as shown in FIG. 5, the target management apparatus 100 that has received the target identification data SID (step S1-Y) specifies the process carry-in date / time IDT or the process carry-out date / time ODT based on the received date / time (step S2).

  Next, the corresponding target management data MSD is retrieved from the received target identification data SID (step S3). Then, the process carry-in date / time IDT or the process carry-out date / time ODT is recorded in the retrieved target management data MSD together with the carry-in identification data IID or the carry-out identification data OID (step S4).

  In the assembly plant that uses the target management system 1000 according to the present embodiment, the above-described processing operation is repeated each time the production management target MMS moves through a plurality of production processes MP (steps S1 to S4). Production status is accumulated in the target management data MSD.

  Therefore, when the manager of the assembly plant confirms the production status of the entire plant in the state as described above, an operation to display the in-process inventory is input to the target management device 100. Then, the target management apparatus 100 that has detected this input operation (step S5-Y) displays and outputs a condition input screen of the inventory transition graph STG on the display device as shown in FIG. 3 (step S6).

  On this condition input screen, input items such as the type of the production management target MMS, the start date and time and end date and time of the graph display range, and the unit period for totaling the in-process inventory are displayed and output. Therefore, the administrator inputs necessary items to these input items.

  Then, the target management apparatus 100 that detects this (step S7) reads the target management data MSD corresponding to the input data (step S8), and calculates the in-process inventory quantity for each production process MP of the production management target MMS for each unit period. From the start date to the end date is calculated (step S9).

  Next, image data of the inventory transition graph STG is generated corresponding to the calculation result (step S10), and the inventory transition graph STG is displayed as an image as shown in FIG. 4 (step S11).

  In this inventory transition graph STG, the in-process inventory quantity of a plurality of production processes MP is displayed on the vertical axis during a plurality of predetermined periods with continuous horizontal axes. Therefore, it is possible to confirm at a glance the transition of the in-process inventory quantity for each unit period in a plurality of production processes MP in a certain production management object MMS.

  Therefore, it is possible to grasp at a glance which production process MP the MMS subject to production management is likely to stay, in which period it is likely to stay, and what is the state of the in-process inventory quantity in the whole factory, and plan improvement. You can

An example of detecting the production management target MMS stocked in the production process MP at a specific date and time by the process carry-in date and time IDT and the process carry-out date and time ODT is exemplified.

  However, the carry-in position reader 210 is installed only at the carry-in position of the production process MP, and the target management device 100 sets the process carry-in date and time IDT recorded for each target identification data SID and the next process carry-in date and time IDT at a specific date and time. The production management target MMS stocked in the production process MP may be detected.

  Furthermore, in the above embodiment, the target management apparatus 100 detects the in-process inventory quantity for each production process MP of the production management target MMS, and the other is a plurality of production processes MP in a plurality of predetermined periods in which one of the horizontal axis and the vertical axis is continuous.
