Next, the parts management server 200 checks the supply request number stored in the supply request number area 510 (step S1214) and compares it with the number of parts stored in the part number storage area (step S1214). S1215). If the number of parts is larger (step S1215: NO), the process proceeds to step S1218.

When the number of supply requests is larger (step S1)
(215: YES), the component management server 200 executes a component supply request (step S1216). Here, the component supply request is an act of urging an operator such as a distribution clerk to supply the component of the received component number to the component shelf 800.
For example, displaying that the component is supplied is displayed on the display unit 620 of the component shelf controller 600. In order to display the indication of component supply on the display unit 620, the component management server 200
The part number information of the part relating to the part supply request is transmitted to the part shelf controller 600, and based on the part number,
A procedure is required in which the component shelf controller 600 instructs which shelf to supply which component.

The component management server 200 determines whether a component has been supplied as a result of the component supply request (step S).
1217) If it is not supplied (step S1217:
NO), and wait until supplied. If a component has been supplied (step S1217: YES), the fact is notified to the component management server 200, and the component management server 200 determines whether or not the mode has been switched to a mode other than the normal mode (step S1218). If the mode has been switched to another mode (step S1218: YES), the component instruction system 100 ends the normal mode to execute another mode.

If the mode cannot be switched to another mode (step S1218: NO), it is determined whether or not a data request button (not shown) provided at or near parts shelf 600 has been pressed (step S1219). When the data request button is not pressed (step S1219: N
O), the component management server 200 waits until the data request button is pressed. If the data request button has been pressed (step S1219: YES), the parts management server 200 proceeds to step S1 to receive the next vehicle information.
Return to 201.

As described above, in the normal mode, the number of requested parts and the number of parts are compared, and if the number of parts stored in the parts storage unit 820 is smaller than the number of requested parts, the supply of parts to the worker is performed. Can prompt and supply parts faster
As a result, the work efficiency of the worker can be dramatically improved. In the component management server 200, the number of times the component has been used can be totaled for each type of component.

Although the embodiments of the present invention have been described above, various changes can be made within the technical idea. For example, in the above-described embodiment, the component management server 200 calculates the number of components stored in each component storage unit 820 and compares the calculated number with the requested number of components to prompt the supply of components. May be performed by the component shelf controller 600 or may be shared with the component shelf controller 600. In this case, the parts shelf controller 600 includes:
A component equivalent to the storage unit 500 of the component management server 200 may be provided, and the control unit 640 may perform processing like the control unit 230 of the component management server 200.

In the above-described embodiment, the lighting of the lamp is shown as the position display means. However, the present invention is not limited to this. For example, the position is displayed on a liquid crystal display device provided in the component storage unit, a buzzer sounds, or the like. Alternatively, a flag may be set.
