Abstract

Customized production is becoming prevalent under smart manufacturing environment. With the increasing high standards from customers, products with satisfied quality are required. However, during some flexible machining processes, defective parts are produced occasionally. In the meanwhile, customized orders (commonly in small-lot) of parts having no defects are desired to be finished within lead times. Dynamic modeling and analysis are required since customized production cannot always reach steady state. Therefore, we investigate the problem in this article. Practical issues, such as unreliable machines and finite buffers are also taken into account. Specifically, a novel building block-based dynamic modeling and analysis method is proposed. The proposed method is validated to have a precise performance measures prediction effect, as well as an efficient computational performance.
