Research On Order Model Of Food Cold-chain Logistics Based On Multi-echelon Inventory Control

With the development of national economy and the improvement of people’srequirement on food quality, the food cold chain logistics development will be gettingmore and more attention. Currently, the study of food cold chain logistics is so less inChina, but the theory about food cold chain logistics multi-level inventory is much less.It is does not match with the need of food cold chain logistics prosperouslydevelopment, which restrains further development of food cold chain logistics.Therefore, this thesis chooses multi-echelon inventory purchasing model of food coldchain logistics as research objective.The research on food cold chain logistics multi-echelon inventory is based on thesingle-stage inventory in this thesis, which mainly takes the production of cold storage,the central cold storage and the market cold storage as the research object. The processanalysis of how to determine best inventory capacity and best purchase amount foreach-echelon inventory under both deterministic demand and stochastic demand.During the study to determine quantity demand of the production of cold storage, thisthesis proposes a new method, which is called layer by layer decomposition. Becausethe cold chain logistics inventory has the function of food preservation, reduce the rateof food spoilage, increasing the use value of fresh food and so on, which constitute aprofit source in the system of food cold chain logistics. So, this thesis use maximizeprofits as the goal to research the cold chain logistics inventory purchase models.The system of cold chain constitutes with many complex elements, which relevantand restricts each other. In order to make the whole cold chain logistics optimal, it isnecessary to adopt a centralized multi-echelon inventory control strategy to makeglobal optimization and control for the cold chain logistics. On the bases of the existresults,this thesis extents the EOQ model considering the realistic problems andparticularity of cold chain, which not only enrich the content of inventory control theorybut also widen the applied areas of the traditional inventory control models, and providemore sufficient scientific evidence for decision makers making inventory decision.
