Research On Storage And Dispatch Of Regional Emergency Resources For The Significant Emergent Events

Emergent events is characteristic of burstiness and urgency, a high degree of uncertainty, complexity, destructive, persistent and derivatives, inevitability and controllability. To minimize the loss caused by emergent events as far as possible, the effective rescue and aid measures must be taken immediately. In the course of the emergency preparedness and response, both for casualties'rescue, safe transfer of a variety of materials and equipments (including hazardous materials and equipments, etc.), or sanitary and anti-epidemic, restoration and reconstruction after the events, so a range of assistance activities all require a large amount of emergency supplies. However, due to the research of emergency management in China start relatively late, the research of emergency resources management is relatively weak. In the actual emergency rescue practice, the situation also exists that as a result of emergency resources reserves and scheduling issues cannot meet the needs of rescue activities in a timely manner. In order to guarantee the smooth implementation of the contingency plans and the development of emergent rescue activities, it is necessary to systematic study on the reserves, allocation, dispatches and transport of emergency resources, for the purpose of the establishment of regional emergency resources security system.Therefore, the requirement analysis of a regional emergency resources, the storage system and scheduling of emergency resources is discussed, the contents of the main research in this paper include:(1) Based on the emergent events classification framework and the contingency plans system of the emergency management in China, further detail of emergencies category is proposed. The method of categories in accordance with material value under normal condition is not fit for emergent situations. Following the principle of categorization accordingto the use value of emergency resources, it can be classified from the degree of urgency, scope of use and the degree of specialization of 3D on the classification, so that we can make relationships between categorization of emergency resources and its reserve way closely.(2) The reasoning framework of the requirement analysis of emergency resources is build, and fuzzy Dempster-Shafer theory and fuzzy case-based reasoning of uncertainty theory is respectively applied to the assessment of emergent events and the requirement analysis of emergency resources.(3) Based on the analysis of the current situation of emergency materials storage in China, the principles and goals of the establishment of regional emergency materials storage system and its management measures are proposed, a kind of emergency materials deposited site layout problem is discussed with established mathematical model, and the solution of the model divided into 2 phases using Particle Swarm Optimization and linear programming algorithm for example analysis.(4) The scheduling problems of the emergency materials after disaster is discussed. Considering more munerous and urgency of the needs of emergency materials, scheduling mathematical model of single-species and a variety of emergency materials in determining the conditions is established to minimize the disaster loss as the target, and its solution is made. For the uncertainty of road transport time, fuzzy set methods is used to select the maximum satisfaction path on fuzzy network, and scheduling problem of emergency materials with the fuzzy travel time and its solution is discussed.(5) Emergency medical supplies demand model based on the mechanism of prevention and control of infectious diseases is established, for public health emergent events, particularly major infectious diseases. The scheduling problem of emergency medical supplies with Time-varying demand is analysed, and its solution examples is listed namely.(6) An overview of the characteristics of accidents rescue and emergency rescue system in China is provided, and the influence factor on the emergency response and rescue resource needs is analysed. Taking into account regional differences, seasonal differences, differences in the occurrence time of accidents, the conceptual model of emergency response and rescue resource requirements is established. For major disaster accident, which there may be more than one rescue sites and insufficient rescue resource conditions exist, the rescue vehicle scheduling model with more than one start sites is presented. Due to randomness of the recovery vehicle travel time, chance constrained programming is used to processing the stochastic travel time of recovery vehicle, under mild assumptions on the probability distribution of stochastic parameters. A genetic algorithm is proposed to solve this model and experimental calculation is conducted to verify the solution approach.
