【摘要】：物流园区进行规划建设中有必要从现代物流系统的角度出发,深入研究客户需求,整合现有物流资源构建物流园区共同配送模式,同时优化物流园区共同配送车辆调度,最大限度的提高物流园区企业物流资源的使用效率,剔除不必要的物流环节,降低企业的物流成本,在提升物流服务质量的同时获取最大的经济效益,因此本文对物流园区共同配送车辆调度优化研究具有十分重要的意义。首先,分析物流园区的含义及分类、配送的含义及发展历程,阐述共同配送为企业带来的效益,同时从企业参与共同配送的情况、共同配送的内容、开展共同配送的目的以及开展共同配送后的效果四个方面对日本开展共同配送情况进行详细,提出在物流园区建设中规划共同配送模式是很有必要的。其次,从物流园区配送现状着手,分析其主要问题,提出物流园区发展共同配送模式的未来发展趋势,同时对物流园区采取的自营配送模式、第三方物流配送模式以及共同配送模三种经典模式进行对比,构建物流园区的配送成本模型,建立基于量本利模型的物流园区配送模式选择模型。最后,分析物流园区共同配送中心配送客户的优先级确定方法,构建基于系统聚类方法和优先度系数模型确定配送客户优先级,同时分析配送过程中所产生各种成本,包括：配送运输成本、配送延迟或者提前的惩罚成本以及超里程补偿费用成本,并构建配送成本函数表达式,同时提出相关约束条件,构建基于优先级的物流园区共同配送车辆调度优化模型,并提出模型的求解思路和算法,并通过算例验证模型的有效性。
[Abstract]:In the planning and construction of the logistics park, it is necessary to study the customer demand, integrate the existing logistics resources, construct the joint distribution mode of the logistics park, and optimize the vehicle scheduling of the logistics park joint distribution from the point of view of the modern logistics system. To maximize the use of logistics resources to improve the efficiency of logistics park enterprises, eliminate unnecessary logistics links, reduce the logistics costs of enterprises, improve the quality of logistics services at the same time to obtain the greatest economic benefits. Therefore, this paper is of great significance to the research of vehicle scheduling optimization in logistics park. First of all, it analyzes the meaning and classification of logistics park, the meaning and development of distribution, expounds the benefits that joint distribution brings to enterprises, at the same time, from the situation of enterprises participating in joint distribution, the content of joint distribution. The purpose of joint distribution and the effect of joint distribution in Japan are discussed in detail. It is necessary to plan the joint distribution mode in the construction of logistics park. Secondly, starting from the distribution status of logistics park, analyzing its main problems, the paper puts forward the future development trend of logistics park to develop common distribution mode, and at the same time, the self-supporting distribution mode adopted in logistics park. By comparing the three classical modes of third-party logistics distribution and common distribution model, this paper constructs the distribution cost model of logistics park, and establishes the model of logistics park distribution mode selection based on volume cost model. Finally, the paper analyzes the priority determination method of the distribution customer in the common distribution center of logistics park, constructs the system clustering method and priority coefficient model to determine the priority of the distribution customer, and analyzes the various costs generated in the distribution process. It includes: transportation cost of distribution, penalty cost of delay or advance of delivery and cost of compensation for exceeding mileage, and the function expression of distribution cost is constructed, and relevant constraints are put forward. A priority based vehicle scheduling optimization model for joint distribution of logistics parks is proposed, and an algorithm for solving the model is proposed, and the validity of the model is verified by an example.
