FIG. 1 is a diagram for explaining an outline of a conventional technique for switching parts. In FIG. 1, when production is discontinued, a replacement part list (T2) is created based on the production discontinuation list (T1). Based on the production discontinuation list, the date on which the stock will run out is confirmed for each item by scheduled inventory inquiry (T3). The parts to be used are switched to the new parts by referring to the replacement parts list for the manufacturing instructions after the date of the stockout (T4). This was repeated for each part.

Therefore, in the present embodiment, in order to smoothly switch over discontinued products, it is possible to simulate manufacturing instructions for using up the switching source parts (old parts) from the inquiry screen (parts delivery schedule inquiry screen). Therefore, it is possible to collectively change the manufacturing instruction information from the switching source part to the switching destination part (new part).

FIG. 2 is a diagram for explaining an outline of component switching according to the present embodiment. In FIG. 2, based on the production discontinuation list (T11), the switching source parts and the switching destination parts are registered in the parts switching master (T12). From the screen for inquiring about the delivery schedule of switching parts, a simulation of the manufacturing instruction for using up the switching source parts is performed, and based on the simulation result, the manufacturing instruction information is collectively changed from the switching source parts to the switching destination parts (T13).

According to this embodiment, by simulating manufacturing instructions that use up the switching source component, it is possible to easily confirm the timing of switching the switching source component to the switching destination component. In addition, it is possible to collectively update the manufacturing instruction information from the switching source component to the switching destination component.
