A Study of the Material Re-Issued Models for an Insufficient Output of the LED Chip Manufacturing Plant

Abstract:

The LED chip manufacturing (LED-CM) is an important process in the LED supply chain. The make-to-order production strategy is a general production model for the LED-CM plants to satisfy the variety requirement of their customers. Because the unstable production output of the LED-CM plants, the effective order fulfillment is low and variety. Under the severely competitive pressure, the production planner will thus confront the issue of material re-issued for an insufficient output of an MO. The purpose of this effort is to meet the required due-date of this MO and to reduce the unnecessary inventory of by-product chips. Therefore, a study of the material (EPI) re-issued MO model for an insufficient output of the LED chip manufacturing plant is proposed in this paper. Three material re-issued models are proposed and detailed discussed first. A real-life LED-CM case is then utilized to demonstrate and evaluate the application and effectiveness of these models. A simulation model is also designed to complete the further experiment.
