ABSTRACT
This chapter focuses on employing constant work-in-process (CONWIP) in an OKP environment. It introduces a CONWIP design framework (CDF). The chapter employs the CDF to make CONWIP scheme for a specific equipment manufacturer. It argues that CONWIP loop structure is the foundation for other CONWIP parameter settings, for example, work-in-process (WIP) limit setting, CONWIP card types, dispatching rules, and others. The chapter reviews the loop structure as the CONWIP loop policy, unless other CONWIP parameters need to be emphasized. The upstream, midstream, and downstream (UMD) identification is a high-level abstraction of the objects controlled by CONWIP. Loop design pattern describes the basic logical dependencies between the abstract class of the UMD and CONWIP loop. The chapter analyzes every production area in the shop floor before UMD identification. Dispatching rule can enhance the workload balancing capacity of CONWIP. The chapter demonstrates how to make CONWIP scheme within a case study.
