Fresh Vegetable Logistics Resources Demand Research Of Beijing

With the development of economy, the relationship between logistics and agricultural products is increasingly connected.However, the logistics can not adapt to the need of agricultural product when fresh vegetable logistics put forward more strict requirements, on this background, the research of logistics resources demands on the development of the rapid and safety of agricultural products supply that has important significance.Based on the Beijing fresh vegetable logistics system, by means of system dynamics,the demands of fresh vegetable logistics resources researchs, for the purpose of optimizing the structure of logistics resources,improving the efficiency of logistics resources.Firstly, explored the meanings of the logistics of agricultural products,the category of agricultural products logistics resources,and the methods for resource demand forecast;Relying on Beijing fresh vegetable logistics system,discussed the theory of agricultural products logistics resource demands.In the fresh vegetables circulation within the space and time of Beijing, the vegetable logistics resource demands and influencing factors of requirements of logistics resources are analyzed.Secondly, the system dynamics method is introduced, vegetable logistics resources system dynamics model is constructed; According to the goal of logistics resource demand forecasting and the relationship between factor, the whole vegetable logistics resources system divided into economics, population system, and logistics resource demands as the specific analysis of the causal feedback loop;On the basis of the causal feedback loop,the transportion and storage resources,which play the dominant role in the system of vegetable logistics,the demand forecasting model are established, to simulate the vehicles and refrigerator demand change trend, providing convenience for management decision makers to make effective logistics resources management decisions.
