A production facility control method for a production facility provided with a guide vehicle configured to transport a plurality of machining targets of multiple types having different shapes in a mixed state on a predetermined transport path as a production line, a plurality of processing tools configured to process the machining targets transported on the transport path, and a plurality of work regions preset in a transport direction of the transport path, each corresponding to a different processing tool of the plurality of processing tools, and each representing a range in which the corresponding processing tool can work to process the transported machining targets, the method comprising:
- controlling the guide vehicle to transport the machining targets from one of the work regions to another one of the work regions arranged on a downstream side in the transport direction, and
- performing movement machining processing in which the processing tool not having the machining target to process in the work region corresponding to the processing tool is moved to another one of the adjacent work regions so as to process the machining target.
