摘要：Flexible manufacturing system has attracted substantial amount of research effort during the last twenty years. Most of the studies address the issues of flexibility, productivity, cost, etc. The impact of flexible lines on product quality is less studied. In addition, many flexible systems implement batch operations to shorten changeover time, reduce cost, and improve quality. In such systems, different types of products are grouped into batches where all parts in each batch have the same type. The change of product type only occurs after the last job in a batch is processed. No study has been found in current literature to investigate the quality performance in batch production environment.

In this talk, we intend to address these issues by applying a Markovian model to evaluate quality performance of a flexible manufacturing system with and without batch productions. Closed expressions to calculate the probability to produce good quality part are derived. Structural properties to address the appropriate batch size and sequence of products are presented.
