【摘要】 物流被认为是降低物资消耗,提高劳动生产率之后的“第三利润源泉”。物流的重要性逐渐被社会所认识到。但企业各自为战的配送活动导致了较高的物流配送成本,对城市交通造成了巨大的压力,同时对环境造成了一定的影响。如何整合社会资源以提升物流作业效率、降低物流成本,已经成为目前物流现代化目标中关键的课题之一。共同配送能够增大配送作业的规模,实现物流资源的快速整合,提高物流资源的利用率,降低配送作业成本,是一种合理化的先进配送形式。从微观的角度看,企业可以达到配送作业的经济规模,提高物流作业效率,降低企业营运成本;不需要投入大量资金、设备、土地和人力等,可以节省企业资源;企业可以扩大市场范围,建立共存共荣的环境。从社会的角度来讲,共同配送可以减少社会车流总量,改善交通运输状况;提高车辆装载率,节省物流处理空间和人力资源,提升商业物流环境进而改善整体社会生活品质。所以,共同配送受到政府和企业的重视。但是,共同配送的开展并非一帆风顺,亟需理论上的指导。研究表明,影响共同配送开展的一个很重要的因素就是共同配送成本如何在参与企业之间实现合理的分摊,而共同配送中心的选址问题也直接影响到合作后的成本消耗状况,能否解决这两个问题将直接影响到共同配送的开展。本文在分析总结前人研究成果的基础上,阐述了共同配送的基本理论,分析了开展共同配送的动机和共同配送的优势以及产生优势的机理,探讨了共同配送的三种实现方式。指出共同配送在开展之初有两个重要问题:一个是如何在共同配送联盟中选择配送中心,另一个是参与共同配送各方如何分配因实行共同配送后产生的成本(费用)的分摊。配送中心作为共同配送运作的基础设施,是构成共同配送活动的神经枢纽,对实施共同配送发挥着重要作用。本文先讨论了共同配送中心的分类,然后分析了配送中心选址的方法,给出一个选址算例,应用MATLAB进行求解。在探讨成本分摊问题时,文章先给出了共同配送成本分摊的原则,然后引入了一次分摊法、二次分摊法、夏普利值法、纳什谈判法和基于权重的群体不满意度函数,分析了各种成本分摊方法的优缺点,给出了共同配送成本分摊模型与方法的具体应用的一个算例,并对计算结果进行了比较分析。最后,对本文的工作进行了总结,并展望下一步的研究。
【Abstract】 Logistics has been regarded as the third profit source after reducing the consumption of production and raising labor productivity. The importance of logistics has been realized by the society gradually. Since many enterprises carry out distribution separately, it has caused high cost of distribution, immense pressure on city traffic and certain effects on environment. Low efficiency of the integration restricted to improve logistic potential power. Consequently, how to integrate social resources to improve logistic operational efficiency, decrease operation cost, has became one of the most important question for discussion in Logistics modernization.Common-Distribution is an effective way to integrate social resources, it causes big scale of distribution, realizes the rapid integration of logistics resources, raises usage rate of logistics resources and reduces the cost of distribution. Form the microcosmically viewing, participant companies could gain scale economic, increase operation efficiency, and reduce operational cost. Participant companies can save lots of resources, because they do not need much capital, equipment, land and manpower. They also gain development and expansion by concentrating on core-business. Common-distribution expanding market bound, breaking close selling net, facilitates establish concomitant, co-prosperity environment. From the macroscopically viewing, implementing common-distribution can bring our a lot of benefit, such as reducing total social traffic flux, allaying the possibility of jam in downtown because of unloading, ameliorating commercial logistic condition. So, government and enterprises are paying more and more attention to common-distribution. However, there are a lot of difficulties in carrying out common distribution and a lot of enterprises feel perplexed to the development. Studies have shown that there are two important factors that affect the development of common distribution are the allocation cost of among the enterprises and how to integrate the DCs which belong to all members in the cooperation alliances. The development of common distribution depends on whether the problems can be solved.Firstly, the paper elaborates the concept, connotation and characteristics based on the achievements of predecessors, analyses the mechanism by which the benefits are caused, and also discusses the function to achieve Common-Distribution. Secondly, we have discussed the categories of DCs in Common-Distribution, analyzed the methods to solve DC location problem. The paper has given an answer to the problems by founding distribution location mathematical models and using MATLAB simulation. Then, the paper has given out principles of cost allocation and introduced five methods. An example has been given and verified the reasonability of the model. Finally, an overview of author’s work and prospect of the research have been presented.
