物流配送客户聚类问题是物流配送研究领域的基本问题,实际问题要求考虑客户分布的地理特性、客户配送量(即需求量)及配送车辆负载量等因素.针对配送中心未知的客户聚类问题,提出了一种考虑配送路网结构和配送量约束的聚类算法.利用所提出的“最短主干道距离”,克服传统欧式距离不考虑配送道路信息的缺陷,在此基础上,利用约束聚类思想对传统后中心划分聚类算法CLARANS进行改进,使其在考虑地理信息的同时,能满足客户配送量和车辆负载量约束.最后对提出的算法进行了数值实验.
物流配送客戶聚類問題是物流配送研究領域的基本問題,實際問題要求攷慮客戶分佈的地理特性、客戶配送量(即需求量)及配送車輛負載量等因素.針對配送中心未知的客戶聚類問題,提齣瞭一種攷慮配送路網結構和配送量約束的聚類算法.利用所提齣的“最短主榦道距離”,剋服傳統歐式距離不攷慮配送道路信息的缺陷,在此基礎上,利用約束聚類思想對傳統後中心劃分聚類算法CLARANS進行改進,使其在攷慮地理信息的同時,能滿足客戶配送量和車輛負載量約束.最後對提齣的算法進行瞭數值實驗.

Customer clustering is a fundamental issue in the logistics distribution study. Considering that retailers are bounded on certain geographic location and the clustering process is highly influenced by the distribution scale (that is the goods scale the customer demand) and loading scale of vehicles, we proposed a customer clustering method constrained by road network and distribution scale, for the clustering process with the location of distribution center unknown. The concept of "shortest arterial road distance (SARD)" takes distribution road information into account, which is ignored by the traditional Euclidean distance. Furthermore, a constrained clustering method for customers based on improved CLARANS was given, which consider the geographic information and fulfill the constraints of distribution scale. Finally, numeric experiments on both synthetic and real datasets justify the effectiveness of the method.
