A Study of the Bin Inventory Allocation Model for LED-CM Plants

Abstract

The LED chip manufacturing (LED-CM) is an important process in the LED supply chain. The specification of an order of LED chips is composed by several feasible bins. A bin is determined by a different lightness grade and wavelength. In order to achieve the optimal throughput or minimum inventory, the inventory of feasible bins must be reasonably allocated to orders. LED-CM plants thus confront the issue of allocating the inventory of different bins to different orders. A bin inventory allocation model for LED-CM plants is thus proposed in this paper. This model can get the optimal throughput and minimum inventory.
