| Frozen aquatic products in Liaoning province in northeast China the realization of the efficient distribution to make reasonable planning for distribution nodes and distribution lines, the existence in the process of cold chain distribution, regional distribution of node density, scattered distribution, multi-distribution links, route chaos and so on, frozen aquatic products in Liaoning province in northeast China cold-chain distribution network layout unreasonable result in high distribution costs, waste of the frozen aquatic products, also affect the development of frozen aquatic products industry in Liaoning province. Scientific and reasonable planning of frozen aquatic products cold chain distribution network, is the key to ensure the frozen aquatic products in Liaoning province of efficient, fast delivery in northeast China.On the analysis of the frozen aquatic products distribution network under the premise of the research status at home and abroad, according to the frozen aquatic products, cold chain logistics, distribution network planning and relevant theory, analyzing the frozen aquatic products in Liaoning province cold chain distribution network in northeast China, designing the two layers of frozen aquatic products cold chain distribution network. Through qualitative analysis to determine the number and location of the frozen aquatic products cold chain distribution node in Heilongjiang and Jilin province, using grey prediction method to predict frozen aquatic products logistics demand in the future five years, according to the number of predicted results calculates the frozen aquatic products in Liaoning province a cold chain distribution node, analysis of the frozen aquatic products a cold chain distribution node site selection factors, building the evaluation index system, using the analytic hierarchy process (AHP) to evaluate the level of cold-chain distribution node location, determining the location of the frozen aquatic products in Liaoning province a cold chain distribution node’s position. On the basis of the number and location of frozen aquatic products have been identified on the cold chain distribution node, on the basis of the minimum frozen aquatic products cold chain distribution cost as the goal, frozen aquatic products cold chain distribution node radiation scope planning model was constructed, using genetic algorithm to solve and determining the optimal allocation scheme of cold chain distribution node, the scheme is analyzed.By the frozen aquatic products in Liaoning province in northeast China cold chain distribution network structure construction, to determine the number and location of frozen aquatic products cold chain distribution node, and optimize the whole distribution network layout, can reduce the frozen aquatic products cold chain distribution link, reducing distribution costs, speeding up the delivery, improving the overall operating efficiency of the distribution of the frozen aquatic products in Liaoning province in northeast China. |
