In this paper we provide an overview of the testing and development framework and implementation issues of our scheduling, statistical operational control, and rescheduling methodologies. Our primary testing and validation methodology will involve the embedding of our scheduling approaches into a simulation environment that captures fundamental components of wafer fabrication. This environment will simulate the information arriving to a Manufacturing Execution System (MES), and the scheduling and rescheduling routines will use this data to determine optimal or near-optimal schedules for the work. In this framework, we will be able to provide statistcal estimates of the performance of our various approaches, and determine if we are improving over current practice. This task entails determining the appropriate software for this approach, the testing of the environment on simple dispatching rules, and then implementation and testing of our shifting bottleneck approaches. Finally, we will incorporate a signaling methodology and fully integrate it with a rescheduling approach, and provide a guide for implementing our approach and integrating it with MES systems.
