Simulation results and formalism for global-local scheduling in semiconductor manufacturing facilities

This article deals with an approach for managing scheduling in semiconductor manufacturing facilities. The proposed approach ensures consistency between global and local scheduling decisions, by ensuring that global objectives are met through dynamic adaptation of the local behavior. This approach is validated by simulation. After describing the context and the framework of the approach, we introduce the formalism and present first simulation results obtained on real data of the fab of STMicroelectronics, Rousset. The experimental tests are promising since substantial improvements are obtained on criteria such as cycle time, number of completed lots, etc.
