摘要：随着经济的快速发展，全球化竞争的加剧，信息技术的飞速革新，物流渐渐成为社会经济生活的纽带，成为沟通生产者和消费者之间的桥梁，在经济生活中占有举足轻重的地位。而配送则是现代物流的一个重要内容，一个企业物流配送环节的设计好坏直接影响到整个物流系统的成功与否。
本文从天猫入手，通过研究发现天猫物流系统仍然存有不足之处1、天猫物流系统存在物流信息系统不完善；2、物流人员的整体素质偏低3、物流配送中心选址不当等问题。诸如此类弊端将导致物流信息得不到及时的跟进和更新，同时也会影响到配送中心各项活动的成本、作业效率、服务水平以及经济效益的下降。为了解决这些问题，本文将综合考虑定性分析与定量评价，利用粗糙集理论获得指标的权重，通过群决策方法获得备选地的综合评价值，求解后能够较好的确定配送中心的分布、规模、数量以及每个配送中心负责配送哪些客户区。本课题致力于完善天猫的整个物流配送系统，提高物流配送作业的工作效率，对增强天猫市场反应能力、降低其成本、以其特有的竞争优势取得更好的经济效益。35106

 Day cat distribution logistics system optimization and design
Abstract：With the rapid development of economy, the competition of globalization, the rapid innovation of information technology, logistics has become the social economic life of the link, become a bridge of communication between producers and consumers, occupies a pivotal position in economic life. And distribution is an important content of modern logistics, a logistics distribution link design quality directly affects the success of the whole logistics system.
      This article obtains from the day the cat to the electronic commerce development characteristics and existing problems of logistics distribution model as the starting point, the research of the third party logistics based on e-commerce environment exist advantages and disadvantages. Through the study found that 1, the day the cat logistics system, such as incomplete logistics information system; 2, the logistics personnel's overall quality is low 3, logistics distribution center location problems such as improper. Such defects will lead to the logistics information not promptly follow up and update, also affect the cost of distribution center activities, operation efficiency and service level and economic benefits. In order to solve these problems in this paper, the comprehensive consideration of qualitative analysis and quantitative evaluation, the weights are obtained by using rough sets theory, through the group decision-making method for alternative to the comprehensive evaluation value, after solving can better determine the distribution center, size, quantity and the distribution of each distribution center is responsible for the distribution which the client area. Through this topic research, can be more perfect day cat of the logistics distribution system, improve the working efficiency of the logistics operation, improve the benefit of logistics and supply assurance degree, ultimately to enhance day cat market reaction ability, reduce cost and obtain competitive advantage in order to obtain better economic benefit is of great significance.
