收益最大化中心选址问题的数学模型

物流中心的选址问题在物流中心的规划设计中占有重要的战略地位，合理的物流中心选址方案可以有效地节约费用，提高企业的竞争力。文章针对第三方物流企业选址的要求，以物流中心收益最大化为目标，并同时考虑物流中心固定运营成本和可变运营成本以及退货所产生的损失费用等因素，建立了一个新的物流中心选址模型。并针对该模型，提出了一种改进的微粒群算法。

A Income Maximization Model of Selecting Logistic Center

The logistics center location occupies an important strategic position for the programming and design of logistics centers. Better logistics center location program can effectively save cost, enhance the enterprise＇s competitive power. To meet the third party physical distribution enterprise＇s requests, take the maximization of logistic center＇s income as the goal, and consider the factors such as the fixed cost and the invariable cost of logistic center, as well as the loss of the returned goods, a new model of selecting logistic center is constructed. According to the model, a new improved particle swarm optimization algorithm is proposed.
