Abstract : In this study, we consider the problem of production planning in the semiconductor industry characterized by high mix low volume production, reentrant flows and complex manufacturing process.The aim of this work is to establish a feasible production schedule that takes into account the limited capacity of the manufacturing system, equipment qualifications constraints and delivery due dates. In this context, we have formulated the objective and constraints in a mixed linear program (MIP). The objective of the MIP is to minimize delivery delays to guarantee on-time delivery. While executing different tests of the MIP, we have reached a limit of resolution in a reasonable time. Thus, we use an approximate method to solve the problem. The results show the effectiveness of the heuristic established as solution quality and time resolution.The obtained results led to an industrial application and a software that provides feasible schedules in reduced execution time in a specific fab.
