中文摘要 | 在物流配銷系統中,區位途程(location-routing)問題主要是選擇候選物流中心位置及物流中心與顧客間的運輸配送路徑,過去文獻中僅考量運輸路徑成本忽略存貨因素,導致物流總成本增加。有鑑於此,本文針對區位途程整合存貨問題提出一數學模式,由於此問題求解屬於NP (non-polynomial),故發展一啟發式探索解,並和過去文獻中以距離成本為評估的兩種方法作一比較發現:本文所發展之方法優於其他兩種方法;同時為了解區位途程問題在不同環境參數下之績效表現,本文探討不同的物流中心數量、運輸量、顧客需求量等相關因子,對物流中心的設置成本、存貨、運輸路徑等相關成本上的影響。 |
英文摘要 | Most literature for location-routing problems in a logistic distribution system is based on the criterion of minimizing transportation costs. The researches on this area focus on estimating distances about these paths and consider minimum costs related to its corresponding traveling cost. However, inventory costs are important and always neglected. It may result in a biased location choice and total cost will increase further. Thus, inventory control and location-routing problem shall be considered together to achieve the lowest total cost. In this paper, a mathematical model for the location-inventory-routing problem is proposed. Since the solution for this model is NP (non-polynomial) problem, we propose several heuristic models to solve the problem. The objective is to minimize the total costs among facility location, inventory and transportation. The results show the proposed method is better than those existing methods based on the total cost criterion. A sensitivity analysis for several parameters is also conducted in this research. |
