中文摘要 | 本文討論多重供應點在不同生產成本函數及不同產能的限制條件下,尋求較佳的 運輸分配方式與生產規劃。同一產品在不同的供應點的生產成本不儘相同,所以在運輸分配 問題中,若只是單純考慮運輸成本,將忽略了很可能影響到整體成本最小化目標的因素-生產 成本。各供應點單位時間的生產量有上下限,未完全分配出去而留在供應點的庫存也有容量 限制。本文對於生產排程與運輸分配整合問題所提出的演算法,分成三個階段進行分配工作: 一為先配送每一供應點的最低分配量;二為分配供應點因產能下限所可能產生的庫存量;三為 同時考慮生產成本與運輸成本來選擇配送方式。本文所提的整合性三階段演算法,由模擬結 果可以得知,需求點的個數愈多,節省成本百分比愈高,但相對地,電腦處理的時間愈長, 整體而言,本文所提的整合性三階段演算法,在需求量為一致分配時節省成本百分比較高, 其次為常態分配,而集群分配所得到的效益較不顯著。在適當範圍內選定車輛裝載容量的情 況下,相較傳統的生產排程和運輸分配兩種模式,確實可以節省包含生產成本、庫存持有成 本及運輸分配成本三個項目的整體成本。 |
英文摘要 | This work addresses the production and distribution of a single product supplied by multiple suppliers and demanded by multiple customers. A production scheduling and vehicle routing model is proposed for the multiple suppliers, multi-vehicle, and vehicle capacity constraint problems. Three stages are proposed as follows: first, the least distributed amount should be distributed from each supplier's locations; second is to distribute the amount of inventory attributed to the constraint of production lower bound of each supplier's locations; and third, vehicle tours are designed by considering both production and transportation cost. The integrated production scheduling and distribution problem can obtain a lower cost solution than the combined solution of conventional production scheduling problem and distribution planning problem. Simulation results confirm the theoretical analysis. |
