Abstract
A system and a method for managing a work-in-process (WIP) workload within a fabrication facility employ sequential processing of the work-in-process (WIP) workload within one each of a minimum of one pre-process tool, a minimum of one buffer tool and a minimum of one post-process tool. A buffer tool tolerance time is calculated predicated upon an available work-in-process (WIP) pre-process rate, an available work-in-process (WIP) buffer capacity and an available work-in-process (WIP) post process rate. The work-in-process (WIP) workload may thus be optimally processed in accord with the buffer tool tolerance time.
