摘要


最終混合生產裝配線各產品之裝配排序,為了配合多樣少量之市場需求及 需求變動,在豐田及時生產系統中,開發了其獨特的平準化方法。然而各 產品的裝配排序,對於混合生產裝配線中,各個零件的在製品數量影響至 鉅。本研究主要採用數學規劃中的 0-1整數規劃,以求得最佳解,俾處理 如何安排產品之投入,以降低零件在製品數量的最高水準。但因解題時間 隨著問題增大而迅速擴大,因此本論文再另行發展下限值的計算方法,利 用狀態空間搜尋策略,使能較有效率的求到最佳解。

In this study, a determining method for the sequence of producting different products on the final assembly line is considered for the production smoothing in JIT production system. The sequence of end-items in a mixed final assembly line affects the quantities of work-in-process (WIP) parts. In the thesis, this problem is formulated by 0-1 integer programming to get an optimal solution. The problem solving time will be rapidly increased with the size of the problem and the lower-bound function of A* algorithm for a final assembly line is explored to get the optimal solution more efficiently in time.
