A modified CONWIP production control strategy for lamp production line

CONWIP is the most studied production control strategy which provides effective tools for production control for multi-stage manufacturing systems in achieving low inventories, short lead time and high throughput. CONWIP has poor control over stage WIP, led to the development of HK-CONWIP, BK-CONWIP and other modification of the CONWIP system. In this paper, a modified CONWIP control strategy BS-CONWIP is elaborated in order to minimize inventories while maximize service level for a lamp production line. To verified the effectiveness and efficiency of the proposed BS-CONWIP strategy, the simulation models is built up on ExtendSim platform. Simulation results show that BS-CONWIP has better performance than ordinary CONWIP control strategy on inventory level, storage cost and production efficiency.
