The Optimization Research Of Logistics And Transportation Service Networks Of Medical Product Cold Chain Based On VaR

In our country, along with the rapidly economic development, various food safety issues flowed, and pharmaceuticals were not spared, occurring throughout the pharmaceutical safety concern. Along with the people to the medical security requirements increase, its pharmaceutical safety problem, especially for refrigerated medical product safety problems will be put forward higher requirements and challenges. The cold medicine maximum security hidden trouble is pharmaceutical cold chain logistics, although China’s logistics industry and logistics industry developed rapidly, but China’s cold chain logistics development level is quite backward, a variety of cold chain equipment, cold chain logistics network system construction, cold chain logistics related operation and the management level and developed country photograph are very backward. At present, China’s pharmaceutical products cold chain logistics in the operation process and transport process each link all kinds of problems, the transport network and transport system interface is not very smooth, safe hidden trouble is one can imagine, so based on the risk value ideas, research pharmaceutical cold chain logistics network optimization algorithm for transportation problem is very essential meaning.This article is aimed at this one major task, based on the relevant theory, namely the risk value, the complex network theory and system theory, fuzzy mathematics theory and optimization theory and application to pharmaceutical products cold chain logistics operation risk control and transportation network of the actual risk control study, establishing pharmaceutical products cold chain logistics transportation network risk evaluation index system and VaR risk measure model. Finally, based on the risk value theory and complex system theory to build pharmaceutical products cold chain logistics transportation network equilibrium model and pharmaceutical products cold chain logistics transportation network, hub-and-spokc network model. The main research work is as follows:(1) Based on a large amount of literature theory research and analysis, from pharmaceuticals cold chain logistics transportation network structure, mode of transport, coordination, management policy and the relationship between supply and demand imbalance, external environment and emergencies and other aspects, analyzed the influence of cold chain transportation network risk of pharmaceutical products for the internal and external factors. And on this basis, from the network invulnerability, network availability, network accessibility, transportation network fitness and network capacity and other aspects, established can reflect the pharmaceutical products cold chain logistics transportation network risk evaluation index system.(2) This section considering the risk of thought and value theory on the basis of the balance, namely in the guarantee cost value, customer value based on the maximum limit reduces the risk. In this risk value balance under the guidance of the thought of combining logistics transportation network risk evaluation index system established risk value measurement model.(3) For pharmaceutical products cold chain logistics activities by process. Interrelated facilities and organizations as well as the route in the spatial structure of the collection consists of cold chain logistics pharmaceutical complex network system. Pharmaceutical products cold chain logistics transportation network equilibrium levels from the distribution network, related facilities construction, and operation service quality from three aspects. Then, to establish a cold chain logistics pharmaceutical goods transportation network equilibrium model and maintain dynamic network model, and the model characteristic of the full range of theoretical analysis, put forward medical products cold chain logistics transportation network backbone network, network node and network node of the trunk channel choice and judgment method.(4) In the cold chain logistics pharmaceutical complex network equilibrium based on combination of pharmaceuticals, cold chain logistics operations, transportation process and a full analysis of the cost and network cost and other factors in the establishment of design of cold chain logistics and transport of pharmaceuticals hub-and-spoke network model. The larger limit established risk resistance low cost logistics network.The research work in this paper helps to analyze and reduce medical products cold chain logistics transportation network system of risk, improve medical products cold chain logistics transportation network operation reliability and stability, cold chain logistics pharmaceutical products for network security strategy and safe operation of providing a relatively scientific basis, for the construction of China’s modern logistics system, improve the pharmaceutical products cold chain logistics security, economy and social benefit to have very important significance for long-term.
