【摘要】 物流节点是物流网络中的重要部分,枢纽设施点是同一层次节点中的中心点,起着一定的中转流通作用。选定枢纽设施点在物流配送应用领域中具有实际意义。本文结合p-中值问题推导出了经由两个枢纽节点的复合配送设施定位模型,以因素评分法作定性分析,结合贪婪取走启发式算法求解模型。通过实例应用计算,证明了模型的实效性和算法的可行性。更多还原

【Abstract】 Logistics note is an important part of logistics net. Hub node is the center node of its level which acts as transshipment and circulation link. To choose the node has the practical significance in the application field of distribution. The model of multiple allocation hub location which has two hub notes and combines with p-median problem is given here. It integrates the factors-grade method which can give the analysis with the greed-taken heuristics to solve the problem. By the application in the example, it proves the model’s effect and the method’s feasibility.更多还原
