The Research Of The Selected Location And Route Optimization Of Regional Clod Chain Logistics Distribution Center

As a fundamental part for fresh farm,food,drug and biological product enterprise,the aim of cold chain logistics is to ensure food and drug safety,also to lower cost and enhance extra profits during the cold chain process,which is a complex systems engineering.Since the quality of cold chain concerned with every family's food safety issue and the cold chain industry becomes more important in nowadays social economy,it is needed to promote the cold chain efficiency and benefit.The delivery of cold chain logistics and distribution center are the most rapid development and the highest level of integration of subsystems,in the cold chain logistics system,as the cold chain logistics system works at the end.The locations of the cold chain distribution center for science,reasonable optimization for cold-chain distribution paths,can largely improve the functionality of the whole cold chain logistics system.In this paper,in combination with predecessors to cold chain logistics,distribution center location,distribution of path optimization research,the author made the two main parts: construction of cold chain distribution center location model,optimization of cold-chain distribution path.In the aspect of distribution center location selection,combining with the distribution center basic network structure analysis,and the characteristics of the cold chain logistics,the article built a cold-chain distribution network,contains the primary and secondary distribution center distribution center,and on the basis of that,made research on cold chain distribution center location optimization problem,put forward the cold chain distribution center location optimization model which aimed as minimizing the system cost and maximizing customer service level,and calculated an example to prove its effectiveness.In study of cold-chain distribution route optimization,according to the characteristics of fresh perishable agricultural products,easy to corrosion are analyzed the composition of cold chain logistics distribution factors,the author built a cost model,which had fresh agricultural products cold chain logistics distribution with time windows,through the research of the cold chain distribution process of fixed costs,transportation costs,damage cost,punishment cost,and simplified the path optimization algorithm,verified the veracity and the rationality and feasibility of the model and algorithm at last.
