Material-handling-system-based input control policy for wafer fabrication

International Journal of Planning and Scheduling (IJPS), Vol. 2, No. 4, 2018

Abstract: In this paper, a new input control strategy is proposed for wafer fabrication facilities. This strategy is an adaptation of workload regulating and CONWIP, and comprises of two sequential steps: 1) determination of operational lot sizes; 2) release of lots based on a material handling system-based CONLOAD approach. We show the superiority of our strategy over a CONWIP-based policy via simulation of a real-life wafer fab. An approach for determining target workload levels for the proposed strategy is also presented.
