A scheduling problem of the color filter manufacturing in TFT LCD industry is considered in this paper. The problem under consideration is a flow shop scheduling problem with sequence-dependent setup times. The objective is to schedule the order completion times as close to the due dates as possible to minimize the earliness/tardiness penalties, subject to the production capacity constraints and fulfillment of production demands. A modified ant colony optimization (ACO) approach is proposed to find the optimal schedule for this problem. The proposed approach was designed to focus on the practical requirements in the color filter process.
Keywords: ant colony optimization, color filter process, earliness/tardiness penalties, flow shop scheduling, setup times
