城市配送中心多目标选址模型与车辆调度仿真研究

Research on Multi-object Location Model and Vehicle Scheduling Simulation of Urban Distribution Center

城市配送中心选址问题是影响物流企业战略发展的重要因素,加强城市配送中心选址研究具有重要的现实管理意义。以物流系统总费用为主目标函数,将目标函数划分为建设费用、车线费用、配送费用三个部分,建立多目标选址模型。提出改进的多重心算法对模型进行求解,以国内某大型物流企业城市配送中心选址规划的相关数据为测试示例,构建中心选址与车辆一体化的车辆运输系统仿真模型,验证了模型和求解算法的有效性。

The problem of urban distribution center location selection is an important factor that affects the strategic development of logistics enterprises. Strengthening the research of urban distribution center location selection has important practical management significance. Taking the total cost of the logistics system as the main objective function, the objective function is divided into three parts: construction cost, vehicle line cost, and distribution cost, and a multi-objective location model is established. An improved multi-gravity algorithm is proposed to solve the model. Taking the data related to the site planning of a large domestic logistics enterprise urban distribution center as a test example, a vehicle transportation system simulation model with integrated center location and vehicles is constructed to verify the effectiveness of the model and algorithm.
