Poisson 수요과정을 갖는 흐름식 라인 생산 시스템의 제어정책 분석

초록

In this study we consider a flow line system in which the processing times at each station follow an exponential distribution and the demands for the finished products arrive according to a Poisson process. The demands that are not satisfied instantaneously are assumed to be backordered. It is also assumed that a bottleneck station exists on the line. For this system, it is important to maintain low work-in-process inventory while satisfying a given level of demand fill rate. Using simulation, we compare the single loop control policies and double loop control policies. From simulation results, we found that double loop control policies yield, in general, better performance measures compared to single loop control policies.
