【摘要】 整个物流系统中，运输子系统是非常重要的，在整个物流成本中，运输成本高达50％左右。所以降低物流成本首先要从降低物流运输成本开始。物流系统的设计应该以能把系统总成本降低到最低限度的运输为基础。所以要根据各种运输方式的技术经济特点，合理组织运输。在设计物流系统时，首先要考虑的是建立整体的运输网络，其次是利用已有的运输网络如何合理地进行物流运输活动。在物流运输系统中，如何选择运输工具，设置物流据点，从物流据点发货的运输计划，配送路线的合理优化等都是重要的设计课题。 本论文的研究就是从物流运输系统的重要性出发而展开的，论文全文包括引言、五章内容以及结束语部分。引言部分简单介绍了物流科学研究的重要意义，指出了人们重视对物流科学研究的重要原因，通过对物流运输系统的成本分析及其功能研究引出了物流运输网络优化研究的重要性。第一章是物流和物流运输网络，介绍国内外物流研究的现状，对运输系统的地位和作用进行了全面的分析。第二章是物流运输网络设计，物流运输网络设计的优劣直接影响到运输成本的高低，本章对物流网点的布局方法进行了深入的研究。第三章是物流运输方式的选择，本章对运输工具的技术经济特征、运输工具的分工与协调、运输方式的综合性能评价以及运输工具的选择因素进行了分析。第四章是物流运输网络优化，本章分析了运输网络优化的重要性，分析了运输优化问题中的特殊约束条件，对直达供货系统和中转供货系统的优化模型进行了研究。第五章是配送路线优化，本章对配送的重要性和配送的经济效益进行了分析，研究出了一系列制定配送路线的确定原则，对配送计划的制定方法和配送中心最佳车辆数量的确定方法进行了深入研究。结束语部分通过对全文内容的归纳和总结，提出了进一步研究物流运输网络优化的方向，展望了物流科学的发展。 笔者希望通过对物流运输网络的优化研究能给物流科学添砖加瓦，希望对社会主义的经济建设贡献自己的一份力量，希望对企业的物流运输运作能有一定的参考价值。笔者知道水平有限，也缺乏实际相关工作经验，文中的观点和理论肯定有诸多不足之处，恳请本领域内外的专家、教授、学者批评指正，笔者在此表示深深的谢意。更多还原

【Abstract】 Transportation is one very important sub-system in the whole logistics system, the cost of transportation is about 50% of the whole cost in logistics system. The first thing of saving cost is to reduce the transportation cost. The transportation cost should be reduced as possible as one can in designing a logistics system. Logistics transportation should be organized properly according to the characteristics of various ways of transportation. In designing logistics system, at first place the integral transportation network should be taken into account, at second place, we must take advantage of the present transportation network to carry out the logistics transportation operation in a proper way. In the logistics system, the focus on how to design the system are as follows: how to choose the ways of transportation, design logistics center, make out the transportation plan for delivering goods from logistic center, optimize the delivery line.The paper starts from the importance of the logistics transportation system. The paper consists of introduction, five chapters, and conclusion. The introduction gives us a brief picture of the importance of the logistics science research, and the main reason why people are paying more attention to it. By analyzing the logistics transportation system cost and studying its function, the introduction introduces the idea that the study on optimizing the network of logistics transportation is very important.Chapter one centers on logistics and logistics transportation network. Presenting the present situation of the study on logistics network, at home and abroad, and giving on overall analysis on the position and function of logistics system.Chapter two focuses on the design of logistics network. The effect of designing the logistics transportation network has a direct influence on the transportation cost, this chapter makes further study on the method of arranging the logistics center.Chapter three analyzing the technological and economic characteristics of transportation tools, the appraisal of the performance of various ways of transportation, and factors in choosing transportation toss.Chapter four centers on optimizing logistics transportation network and its special restricted conditions, studying on the optimizing model of direct delivery system an indirect delivery system. By illustrating the importance of delivery, and analyzing the economic returns of delivery.Chapter five works out a series of rules in designing the delivery lines, and studying how to make the delivery plan, and how to decide the right vehicle number of the delivery center.The conclusion gives us some directions of further studying logistics science, and looking forward to the development of logistics science and business.Finally I hope the theories of the paper will be useful to the operation of the business logistics, if it is, I will be very pleased. As for the level of the writer, there are deficiency and inaccuracy, I would be very glad to appreciate criticisms and suggestions from professors, learns and other readers.Zhu Muyi (Traffic Transportation and management) Directed by Zhao Gang (Professor)更多还原
