Study On The Emergency Logistics System

With accelerated development of economy globalization, industrialization and urbanization of most country, serious natural calamity, accidents, public sanitation incidents and social security incidents happen occasionally, and new problems emerges endlessly. For one hand, these sudden public incidents could cause huge casualties and property losses, thus a large quantity of emergency materials would be needed to avert deterioration, reduce casualties and losses, facilitate the reconstruction and renew its manufacture. For the other hand , the development of science and technology improves the ability of predicting those incidents, a majority of serious natural calamity, accidents, public sanitation incidents and social security incidents are difficult to predict or the interval of their predicting time and happening time are too short, which lay high requirements to emergency logistics system. Therefore, the research on emergency logistics system is of great realistic signification.Beginning with the base theory of studying emergency logistics system, the paper introduces emergency management theory and modern logistics theory, including their concepts, characteristics and etc., it lays basis for further research. Then, the paper expounds the concept and characteristics of emergency logistics, and discusses the organization and function of emergency logistics system and how to construct the ensuring mechanism and information system. The fourth chapter studies the location problem of emergency logistics center. On the basis of summarizing existing methods, the paper put forward emergency logistics center location model ,which is combining the analytic hierarchy process and goal programming for location model of emergency systems, and prove it feasible with an example. Finally, the paper studies the problem of material dispatch of emergency logistics system. At the situation of existing emergency logistics center, the paper studies material transportation schemes aiming at two different system, one-time exhausting system and continuous exhausting system,and proves them with examples each.
