The invention relates to a method of production control and a method of manufacturing industrial products. It is an object of the invention to provide a method of production control and a method of manufacturing industrial products which make it possible to set a target processing quantity of a process appropriately set and to improve the throughput of a production line as a whole. A method of production control for a production line including a plurality of processes is provided, in which a target processing quantity Lk for a process Pk is obtained from:()=0()where the processes are represented by Pn (n=1, 2, . . . , k&#x2212;1, k, . . . ) in the order of their closeness to warehousing; Nk represents a total quantity scheduled to be warehoused from a day as a starting point until after lead time Tk from the process Pk up to the warehousing passes; and SKk represents an expected cumulative quantity completed, which will contribute to the warehousing, among work in process which has passed through the process Pk.

Method of production control and method of manufacturing industrial products

A plurality of subsidiary transport paths are disposed crossing a main transport path, for transferring a workpiece. A stocker is disposed at each cross point between the main transport path and each of the subsidiary transport paths. The stocker transfers the workpiece to and from the main transport path and a corresponding subsidiary transport path and temporarily stocks the workpiece. A plurality of processing apparatuses are disposed corresponding to each of the subsidiary transport paths. The processing apparatus receives the workpiece transported on a corresponding subsidiary transport path, processes it, and returns it to the corresponding subsidiary transport path. An efficient transport as a whole can be realized.
