摘要

A new kind of work-in-progress control system (I-WCS) is proposed, in which two control algorithms, the proportional & integral control (PI) and the statistical process control (SPC) are integrated to maintain a reasonable amount of work-in-progress (WIP) in discrete manufacturing systems. Taking the production line of certain motorcycle engines' crankcases as an example, its I-WCS system is proposed. It consists of two integrated controllers, which are able to collect real-time production data, draw Shewhart control charts, and get these charts analyzed and acquire real production scheduling schemes. Simulation results show that I-WCS can maintain lower and steadier WIP in production lines so as to improve the ability of on-time delivery.
