Abstract

A light-emitting diode (LED) light bar for display monitor may be composed from thousands feasible LED combinations due to supplies of LED bins featured by voltage, illumination, and chromaticity. To control inventory levels by bins, this work proposes a novel multi-level linear programming based system capable of maximizing LEDs allocations of light bar work orders. Filtering from feasible LED combinations by the control table based operations, the target LED bins enable solving of each programming model by levels efficiently. A case study in the TFT-LCD industry demonstrates that the proposed system can control inventory levels of the remaining LED bins and reduce more than 70% of the original computational loads, allowing allocation of LEDs for work orders in mean 1.73 min.
