An Optimized Study On The Emergency Resource Distribution After The Disaster

Natural disasters not only result in the loss and damage of human lives and properties, but also make negative impact on the national economic development. Though, the damage of disaster is unavoidable, if we can enforce some precaution strategies against natural disaster before it happens, immediately collect information about the calamity, and efficiently distribute resources to the disaster areas and relieve sufferers, then the damage can be reduce to the smallest. Therefore, an effective planning of disaster resource distribution system will determine the performance of rescue work.Whenever a major disaster occurs, policy-makers must make an appropriate scheduling of relief personnel and relief equipment and materials in a very short time, in order to effectively reduce the disaster staff and property damage. In the past, how to allocate and transport the emergency materials was decided pragmatically by people, which lacked optimal systematic analysis. Even though the strategy could handle the situation, it did not achieve the optimal effect. Accordingly, taking the scarcity of the materials and the urgency of transporting them into consideration, this study aims to build a model of allocating and transporting the emergency materials so that the policy makers can optimize the problem of allocating and transporting the emergency materials within the shortest period of time.This study will employ network flow techniques including both time-space network of emergency transportation flow and that of emergency materials flow. Depending on the nature of different emergency materials, the multiple time-space networks include various time-space network of transportation flow which specifically corresponds to the time-space network of each different emergency material flow. A formula has been developed to arrange the routing of traffic and material flow; nevertheless, the routing is also simultaneously modified by the practical operational procedures. Fundamentally, the model deals with multiple layers of networks matching transportation flows with various material flows. This study will develop a logarithm, which employs LINGG08.0 to solve the problem. To evaluate the model and the solution algorithm, this study will perform a case study using the data collected from the warehouses storing flood control and flooding emergency materials by simulating some typhoon to raid, water resource agency, ministry of economic affairs, the result shows that the effectiveness achieved by applying the model is better than that by pragmatic decisions. Finally, this research use the sensitivity analysis to understand which parameter can influence on the target value. Then, the policy-maker makes the most suitable decision-making of allocating and transporting the emergency materials after the disaster...
