Abstract

This study is a response to the observation that little attention has been paid to the relationship between production (manufacturing) system design and product quality. In particular, only very limited work exists analyzing assembly system quality when multiple products are produced in the same system. Here, a computational scheme to estimate material, capacity and resource requirements in assembly manufacturing systems with imperfect quality is proposed. Accurate estimation of these requirements is vital to system design. The proposed scheme integrates the design of both production and inspection systems, accounts for inspection errors of both types—missing defective units and false rejection—and enables the comparison of alternative designs. In addition, the structure of the inspection system significantly affects both the volumes of material flows and the structure of the material flow network. These ramifications of imperfect quality have been overlooked thus far, but are also examined and discussed in this study.

摘要

这项研究是对观察很少关注生产（制造）系统设计和产品质量之间的关系的回应。特别是，当多个产品在同一系统中生产时，分析装配系统质量的工作非常有限。在这里，提出了一种计算方案，用于估计质量不完善的装配制造系统中的材料、产能和资源需求。准确估计这些要求对于系统设计至关重要。提议的方案集成了生产和检验系统的设计，解决了两种类型的检验错误——缺少缺陷单元和错误拒绝——并能够比较替代设计。此外，检查系统的结构显着影响物流的体积和物流网络的结构。到目前为止，这些不完美质量的后果都被忽视了，但在本研究中也进行了检查和讨论。
