The Study On The Model Of Cold Chain Logistics Distribution Centre Location

In the recent years, With the development of economics, science and technology, logistics becomes more and more important place and it takes our attention gradually, so that a country physical logistics integrated development level became judges one of its national synthesis strength symbols.With the developments of the social economic, the rhythm of people's work is hastened, people's demands for fresh frozen foods are growing. The retail merchant in order to raise its service level, increasingly also have high requests to the city cold chain logistics centre business, logistics centre development becomes restricts Our country logistics Enterprise how to design and reconstruct enterprise's distribution system and enhance the distribution efficiency. the critical question is the problem of logistics distribution center location. The logistics distribution center. location decided the entire distribution system pattern and the structure, defined the distribution system operation, selected method and related cost. Therefore the research construction of minimum-cost mathematics model has the important theory and practice significance.The paper summarizes the related research theory of the location of logistics center. The paper are planed to analyze the developmental situation in the cold chain and point out the problems in the development of China's cold chain in theoretical and practical way. The paper established the model of cold chain distribution center location in a qualitative and quantitative way according to the commodity distributedThis paper summarized and reviews the literature of location of distribution centre , introduced the domestic and foreign development present situation and the method which used; analyzes the system of cold chain, summarized the basic theory, the basic method and the basic model on location of distribution centre and discuses the influence factor of the cold chain logistics distribution centre location. Then,discusses the procedure model of the cold chain location of distribution centre master the process and procedure of the cold chain logistics distribution centre location Then establishes a comprehensive cost optimization model for this distribution system under the restriction of service levels about cold chain and bring forward the arithmetic, mixed genetic algorithm to the model established. Finally through the analysis and the computation of the concrete example has proven the rationality and the feasibility of the model. The research conclusion of this paper may provide the cold chain logistics enterprise the reference of the pursuit of the minimum allocation overall cost on the basis of selecting location for the cold chain distribution, which has the good application value.
