| Summary: | 碩士 === 華梵大學 === 工業工程與經營資訊學系碩士班 === 97 === The seasonality factor has strong impact to the market demand of the pre-recorded CD industry. The transition between seasons creates a significant difference in demand pattern that in term causes the bottleneck floating between workstations, an inevitable situation that makes the effort of managing such production is even more difficult.
In order to reduce the risk of late delivery, the research developed a small order strategy, a large order strategy and a mixed order strategy based on the demand patterns of the off-peak demand season, peak demand season, and the transition period between these two seasons, respectively. The small order strategy increases the utilization of the molding station through outsourcing and capacity searching. The large order strategy solves the order delay problem by making extra copy of the masters whenever needed. The mixed strategy combines the two strategies and applies the characteristic from the parallel machines to improve the shifting bottleneck problem.
The results indicate that the three methods developed in this research do have good performance in the on-time delivery, the average flow time, the average lateness, and the number of tardy jobs in their intended settings.
