The results management server 10, the parts ordering server 20, the material terminal 30, the parts replenishment request terminal 50, and the parts replenishment receiving terminal 60 are connected by a network 40 such as a LAN (Local Area Network).

  First, an outline of the system will be described. When it is necessary to replenish parts at the assembly shop, the operator inputs a product tag 70 to the parts replenishment request terminal 50 as an input device. Then, the component replenishment request terminal 50 transmits component replenishment information described later on the actual product slip 70 to the result management server 10. The result management server 10 that has received the parts replenishment information makes an inquiry to an inventory management system (not shown), and if there is a stock, the parts replenishment receiving terminal 60 in the parts warehouse processes parts replenishment. The parts replenishment receiving terminal 60 outputs the actual product form 70. The person in charge of distribution at the parts warehouse attaches the output actual product form 70 to the parts for which the corresponding parts have been replenished, and distributes them to the corresponding assembly shop. As a result of inquiring to an inventory management system (not shown), the results management server 10 performs an ordering request process to the parts ordering server 20 when there is no inventory. The component ordering server 20 performs an ordering process with respect to a supplier (for example, a component manufacturer or a trading company). Here, as an example of component replenishment contents, component replenishment of components for attaching components to an electronic circuit board is taken as an example. In FIG. 1, the parts replenishment request terminal 50 is installed at the assembly shop (work site side), but may be installed at the parts warehouse side. At this time, when the person in charge of distribution in the parts warehouse needs to replenish parts, the in-stock item 70 is inserted.

  The actual product form 70 includes a sheet 71 and an IC tag 72. The sheet 71 is a sheet in which information in the IC tag 72 in which information necessary for component replenishment is stored is written in characters so that an operator can visually understand the contents. It is a sheet that can be erased. The IC tag 72 is a non-contact wireless IC tag such as RFID (Radio frequency identification).

  The parts replenishment request terminal 50 is a terminal into which a product tag 70 is inserted when parts replenishment becomes necessary. The parts replenishment request terminal 50 is attached to the side of the box 51 having the insertion port 53 and the discharge port 54, reads the IC tag 72, transmits the read information to the results management server 10, and the sheet. A component replenishment request terminal main body 52 that can rewrite the writing of 71 and a tray 55 that holds the discharged actual product form 70 are provided.

The component actual consumption list is arithmetically processed by the processing unit 11 in accordance with an arithmetic execution command from the input unit 14 of the actual result management server 10, a list is created, and stored in the data 154 when the component consumption is completed. The processing unit 11 calculates a component consumption time (consumption L / T) from the component management data 151 in the storage unit 15 and stores it in the component consumption completion time data 154. Specifically, in the case of the actual product slip A1001, the arrival date of the parts is 13:00 on August 23, 2006 and the replenishment request date of the parts is 11:40 on August 25, 2006. L / T is 2 hours 1 hour 40 minutes (002 1:40). Based on the consumption L / T, the storage cost data 152, and the interest rate data 153, the L / T storage cost and the L / T interest rate are calculated. In the case of FIG. 9, the storage cost is 33 yen per day and the interest rate is 19% per year. In the case of the actual item A1001, the purchase price is 800,000 yen, but considering the consumption L / T, the price at the completion of consumption is 800,899 yen. Thus, the ratio (consumption value at the time of completion of consumption / product value of purchase price of 100) is 100.1%.

  Further, in the case of the actual product slip A0001 in FIG. 9, the consumption L / T is 367 days, which is a long period, and therefore the ratio is 120.3%. In the actual product slip A1004 and the actual product slip A1006, the consumption of parts is not completed, but the consumption L / T at 16:00 on January 4, 2007 is calculated.

  In response to a display command from the input unit 14 of the result management server 10, the component result consumption list is displayed on the display screen of the output unit 13, and the administrator can grasp the current component consumption state. At this time, the processing unit 11 searches the data 154 at the time of completion of parts consumption, and when the purchase price at the time of completion of consumption exceeds a predetermined price and at least one of when a predetermined ratio is exceeded. It is preferable to mark the number and notify the manager. The manager or person in charge of the material section can easily determine that the consumption L / T of the part corresponding to the marked material order number is long and the purchase price when the consumption is complete is high. For this reason, it is possible to take measures to reduce the number of replenishers when ordering the next part. Or, since it is considered that the parts are not likely to be used at present, it is possible to cancel the next order after confirming with the design section or the like.

  According to the present embodiment, it is possible to measure the part consumption time during which parts are actually consumed from the delivery to the material warehouse, and it is possible to manage long-lived parts and the like.

The component replenishment request terminal main body 52 includes an IC tag reader / writer unit 521 for reading an IC tag, and the read information is recorded in the results management server 10. And a communication unit 523 for transmitting to. The performance management server 10 includes a storage unit 15 and a processing unit 11. The processing unit 11 indicates a communication start date and time included in information transmitted from the component replenishment request terminal 50, or a date and time when the information is received. It is characterized in that it is registered in the storage unit 15 as the parts replenishment request date and time. According to such a configuration, the replenishment request information for the parts of the IC tag placed in the box 51 is collected by the performance management server 10 and registered in the storage unit 15.

  The component replenishment request terminal main body 52 (see FIG. 1) of the present embodiment has the sheet rewriting unit 522. However, when it is determined that the sheet 71 needs not be rewritten, the sheet rewriting unit 522 is omitted. May be. Moreover, although the box 51 of this embodiment has the discharge port 54, it may not have the discharge port 54. At this time, the operator, when requesting replenishment of parts, inserts the actual product form 70 from the insertion port 53 and then a predetermined time later (the IC tag reader / writer unit 521 reads the IC tag, and the communication unit 523 reads the read information). After sending to the results management server 10, it is preferable to take out the actual product form 70.

  In the embodiment described above, the IC tag 72 put into the box 51 has been described as the component identifying IC tag. However, the IC tag is not limited to the IC tag 72 for component identification. For example, there is a tool identification IC tag that identifies a work tool.
