Abstract
Rework Strategies are indispensable in order to improve the process reliability of reconfigurable manufacturing system (RMS). Process reliability is an integrated measurement of production ability of RMS, which serves as a performance indicator of the production process under specified technical constraints, including time, cost and quality. The process reliability of RMS with rework process is studied, and the rework process is decomposed into one general processing path and several reworking processing paths. A novel model and algorithms is introduced to obtain the inputs, outputs, costs, and process reliability of each machine, as well as the rework strategies under different batch size of RMS based on process reliability is presented. Case study on machining process of slide valve is employed to illustrate the proposed algorithm, which shows that the proposed methodology can make the rework strategies of RMS effectively and efficiently.
