Abstract
Wafer fabrication is the most complex and capital-intensive stage of semiconductor manufacturing, characterised by re-entrant flows, diverse equipment types, batch and discrete processors, sequence-dependent setups, machine failures, and high variability. This research develops and evaluates new Closed-Loop Order Release Control (CL-ORC) policies that regulate system workload, control WIP, and ensure reliable due-date performance. Three newly proposed CL-ORC policies are empirically validated against 17 existing policies using due date-based performance measures, and shown to offer actionable insights for improving due-date performance in wafer fabrication environments.
