A Simulation-Based Approach for Operational Management of Time Constraint Tunnels in Semiconductor Manufacturing : *Topic: IE: Industrial Engineering

Semiconductor manufacturing processes include more and more (queue) time constraints, often spanning multiple operations, which impact both production efficiency and quality. This paper presents a discrete-event simulation-based approach to support operators who manage lots under time constraints in a high-mix manufacturing environment. After motivating and stating the problem of managing time constraints, the main characteristics and capabilities of the proposed approach are presented. The approach is then validated with respect to the ground truth. Computational experiments conducted on industrial instances are discussed before providing conclusions and perspectives.
