食品冷鏈物流配送管理研究
[Abstract]:After years of development, the traditional logistics theory in China has gradually matured. However, as a special logistics, cold chain logistics has not been given due attention. However, with the development of national economy and the improvement of people's demand for food, the development of food cold chain logistics will be paid more and more attention. This paper analyzes the current situation of food cold chain logistics in China from two aspects of demand and supply, summarizes the problems existing in the development of food cold chain logistics in China, and puts forward corresponding suggestions for the development of food cold chain logistics. Cold chain logistics store and transport perishable and easily spoilage frozen refrigerated food, so food quality is the lifeline of cold chain logistics. The quality change of cold chain food was studied and the effect of low temperature on cold chain food quality was analyzed. In this paper, the application research of hazard analysis and critical control point (HACCP) is extended, and the application of HACCP in cold chain logistics of food is discussed. Based on the traditional vehicle routing problem, this paper analyzes the distribution characteristics of frozen and refrigerated food routes and constructs related cost functions, including the cost of goods damage caused by food corruption. The penalty cost caused by violating the time window of customer demand, the refrigeration cost of refrigerating equipment consumed during distribution, and the transportation cost in the traditional vehicle routing problem, etc., are aimed at minimizing the sum of the above costs. The mathematical model of cold chain logistics distribution path is constructed, and the ILOG OPL program is written to solve the model, and an example is analyzed.
