Aide à la décision pour la conception et la gestion de systèmes de transport automatisés complexes

Abstract : The manufacturing of semiconductors is a long and very complex process with many constraints. The process of manufacturing a lot can last several months with several hundred operations. Several thousand lots must be transported and stored permanently. An efficient transportation system is therefore critical to ensure that the hundreds of machines in the factory are delivered on time.This thesis focuses on the modeling and optimization of a transport and automated storage (AMHS) system in a modern semiconductor manufacturing unit.Different issues have been studied. The first aimed to analyze the impact of key parameters of the AMHS system and to propose new approaches to determine these key parameters. A simulation model has allowed to validate the results obtained. The second issue focused on the management of crisis situations related to one or more failures on the network, with the aim of minimizing disruption to the operation of the AMHS system. The last issue concerns the design of a new AMHS system for the transportation of auxiliary resources in a specific workshop.These thesis work was carried out within the framework of a CIFRE agreement between the Ecole des Mines de Saint-Etienne and the Crolles site of STMicroelectronics. The proposed scientific approaches have led to several industrial applications in use.
