The Research On Region Emergency Logistics Distribution Network Under The Geological Hazard

Geologic hazard means geologic phenomenon that cause life, fortune loss and environment damage, which is formed by the force of nature or man's behavior. Our country is one of the most serious countries harmed by geologic hazard, which has many kinds of disasters and is high in frequency, wide in geographical distribution,result in great loss. Although many countries regulate emergency rescue work in the form of Act,it but just stay in the material reserves, management responsibility allocation ,and so on. Mostly it just act as rescuing on play in spot after disaster.In fact, carrying out emergency logistics not only need the national laws to regulate,meanwhile it need more scientific theories and methods to guide the specific details.since 2006, our country hasgradually started to attach importance to nature disasters, but from the view of the emergency commodities and money supply and allocation in May 12, 2008,Sichuan Wenchuan's earthquake, it can be still able to reflect the defect and shortcoming of our country's emergency logistics management.therefore, the selection of region emergency logistics distribution networ under geologic hazard is of great important theoretical and practical significance.The main content contains 6 parts:The first part is introduction, introducing the topic background and significance, and generating the passage's research content, frame structure and research method.The second part mainly describles the basic theory of the modern logistics management, geology, geography, diagram theory and so on. The main problem faced in rescuing under great geologic disaster is the selection of emergency logistics distribution centre site and distributional way.The third part is to research the site selection of logistics distribution centre under geologic hazard, firstly analyze the factors influencing the site selection of logistics distribution centre under geologic hazard, from the part of security, economy, technology and society factors and so on to rebuild the index structure of site selection of logistics distribution centre, and the use the ANP theory and SD software to solve building the hierarchy structure model of site selection of logistics distribution centre under geologic hazard.The fourth part is region emergency logistics distribution network research. It firstly probe into the characteristics of region emergency logistics distribution network under geologic hazard and factually occurring problems, and then aiming at less circumstances of the emergency logistics allocational stuff at the beginning, drawing into the TSP model the network design of region emergency logistics distribution network under geologic hazard. And solve with the Prim method, and and use the method of solid network transformation to solve the groups of allocation problems.The fifth part is practical research of Longnan city in Gansu province. The casualty and fortune loss of Longnan city of Gansu province is just second to Sichuan province, after researching emergency logistics distribution centre and network according to the environment of Longnan city, Chen county is emergency logistics distribution centre theoretically, the best way of the surrounding area's emergency logistics distribution that take Cheng county as centre mainly divide into four groups: Chen county-Liangdang, Chen county-Kang county, Chen county-Xihe-Li county -Wudu- Dangchang, Chen county- Wudu-Wen county.Lastly it reviews the research result, and proposes the vision of future research.
