Research On Constructing Of Emergency Logistics System For Defending Disaster In China

China is one of the 1arge developing nations in the world with the most serioushit by natural disasters There are many kinds of natural disasters hitting the countryfrequently and extensively and resulting in huge 10sses to the nation The naturaldisasters have posed great threat to the 1ives ofthe people．its indirect economic 10ssestogether with derivative finaacial 10sses and the direct economic 10sses areintertwined．making the impact on the national economy being multi—level aidmulti—aspect and thus．seriously endangers national economic development and theprosperitv aid stabilitv of the socieIV．Since natural disaster relief work is acomplicated system．in which 10gistics securitv for the disaster emergency reliefcomposes very important part of the whole system．the key to the success of thesmooth operation of the system is whether it is possible to build a capable．highefficient and stable 10gistics systemThe so—called 10gistics for the disaster emergency relief in national disasterconditions refers to the kind of special 10gistics activities in which emergency reliefsupplies are provided to pursue the maximal emciency oftime and minimal 10sses Toestablish 10gistics securitv system for the disaster emergency relief in order to achievethe following main goals:r1,firstly 1 te．,when the nationa disas r occurs to ensureadequate supplies of relief materials；(2)secondlN to minimize the response time tomeet the time limit for the supplies ofreliefmaterials；(3)thirdly,on the premises thatrapid supplies of disaster relief materials are met,to reduce emergent logistics costs,1essen unnecessary waste and 10sses111is paper first describes from the perspective of system theory the concept andits characteristics of 10gistics for disaster emergency relief on the process of operationof emergency 10gistics．its system architecture and the functional requirements It thenanalyzes the temporal and spatial dis订ihution of the earthquake．floods．snowstorms．tvDlloons and other national disasters in China．and the rule of occurrence of nationaldisasters．to study the tvpes and quantities demanded for reserves of disaster reliefmaterials and put forward the ideas for dis订ihution of disaster relief supplies Next．the paper studies the issue of choosing a place for building emergency logistics centerExperienced on current method for choosing the location,the paper discusses logisticscenter location models by applying Quantitative method and Qualitative method andprovides examples to verify them Finally,the paper studies the issue of transport ofdisaster relief supplies,building of transportation scheduling system architecture,andanalyzing advantages and disadvantages of the various models for transporting reliefsupplies and its applications,outlining the guide for designing oftransport route and itspecifically studies the use of Dijkstra algorithm for computing shortest route fortransporting relief supplies...
