Abstract
Production control systems can be generally categorized as push or pull
systems. In a push system, production is initiated at scheduled times, whereas in a
pull system, production is initiated when a signal is received. However, there are
limitations to each system. Push systems are controlled by observing throughput,
which requires an estimation of system capacity. Inaccurate estimates can cause
work-in-process (WIP) to increase beyond the limit. Pull systems require maintaining
a small amount of WIP for each product family. Nevertheless, a large product mix
may still result in a high WIP level. The aim of this research is to develop and
investigate a new pull system (made up of several variants) known as a parallel
constant work-in-process (CONWIP) system. In the systems, product families are
classified into two classes (high-runner and low-runner) based on the demand of the
product mix. Each class uses a CONWIP system, where production is initiated upon
withdrawal of finished goods.
