Abstract: The invention relates to a method of production control that is preferably used for manufacture of electronic apparatus such as liquid crystal displays and provides a method of production control that makes it possible to set a feasible quantity to be processed. In a method of production control for a production line having a plurality of production steps, a tentative target quantity to be processed is set for a major production step; the tentative target quantity to be processed is set as a target quantity to be processed when the quantity of work in process that can be actually processed is equal to or greater than the tentative target quantity to be processed; and the quantity of work in process that can be processed is set as the target quantity to be processed when the quantity of work in process that can be processed is smaller than the tentative target quantity to be processed.

Abstract: 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: Lk=Nk?SKk(Nk>SKk) Lk=0(Nk?SKk) where the processes are represented by Pn (n=1, 2, . . . , k?1, k, . . .
