Agricultural Product Logistics Center Location Model And It's Application

China is a huge agricultural nation, so agriculture is very important to Chinese economy, and now, agriculture affects the national economy development. At present, the bottleneck that affected the agricultural development changes from the realm of production into the current distribution. It becomes a prominent question that the circulation of agricultural product has low marketability and high cost. So, developing agricultural product logistics becomes the key point to help the agricultural product compete in the international market, to promote agriculture development and to increase the farmer's income.Selecting a reasonable site for the logistics center can improve logistics efficiency, reduce the cost of logistics, so study the location of agriculture logistics centers problem deeply has important theory meaning and using value. The thesis stands on the standpoint of agriculture products logistic enterprises to considers the location of logistics center, and analysis the construction and running situation after building up of the agriculture products logistics center based on the traits of agricultural product logistics and agricultural product logistics center. The thesis sum up the location of the agricultural product logistics center as the minimum cost question that means minimizing the logistics cost and the operation cost, and set up location models for the minimizing sum goal of logistics cost and the operation cost.This thesis includes five parts:Part one IntroductionThis part briefly introduces the research background and meanings of the agricultural product logistics, then summarizes the research trends on domestic and in the international, and finally respectively states the research method and the creative points.Part two Theories of Agricultural product LogisticsThis part introduce the meanings of logistics, agricultural product logistics, agriculture logistics and agricultural product circulate; introduce the theory of supply chain management, environmental logistics and logistics cost control.Part three Traits, Actuality and Problems of Agricultural Product Logistics in ChinaThis part analysis the traits of agricultural product logistics, and analysis the actuality and problems of agricultural product logistics in our country.Part four Theories and Location Models of Logistics CenterThis part introduces the meanings of logistics center, the kinds of logistics center and the function of logistics center, and describes the importance of the location of logistics center, the principia and the variety of the location of logistics center, at the last, introduces five different location mathematic model, for example, CELP Model, Baumol-Wolfe Model and Mixed integer programming.Part five Constitution of agriculture products logistics center location modelIn this part, based on the traits of agricultural product logistics, constitute two kinds of different agriculture products logistics center location models for the minimizing sum goal of logistics cost and the operation cost, one model considering the lost of agricultural product when they are distributing, and the other considering the time limit.Part six ConclusionThis part summed up the main content of this thesis, and pointed out the flow of the agriculture products logistics center location models, and gave some amelioration suggestions.
