Study On Dynamic Allocation Of Singal Post-Earthquake Rescue Resources

Since the reform and opening up, with rapid economic development of our country, the modern society of personal and social urbanization improves the concentration of wealth. The influence of emergency which threaten and bring losses to people is great. In recent years, the frequencies of natural disasters in our country have brought huge losses to the development of cities and economy. How to improve the responsiveness of emergency has become an important part in emergency management. How to improve efficiency of using limited resources in order to save more life and property has become a problem which is urgently to be solved for researchers in relevant fields.Taking earthquake as the background, this thesis attempts to discuss the allocation of multiple disaster-affected areas and multi-stage rescue resources, which takes the amount of survivals as the aim. Firstly, it reviews and concludes the research status at home and abroad, pointing out the main research orientation of this thesis. Secondly, on the basis of analyzing the classification of emergency resources, according to the experience of Wenchuan earthquake and international humanitarian relief efforts, this thesis summarizes the specific classification of post-earthquake rescue resources and makes a detailed exposition on rescue resources.Thirdly, this thesis adopts quantitative analysis in analyzing the needs of post-earthquake rescue resources. It assumes five consecutive existential states for disaster-affected people, building state transition matrix, summarizing the transferred multi-stage matrix, working out an estimation model referring to historical data and analyzing the examples. It provides reference value for security reserves of emergency resources, improving the responsivity for future emergency management.During the short time after earthquake, because of the great needs of different rescue resources, a kind of rescue resource sometimes satisfies the needs of one disaster-affected area at different times, but the other rescue resources are hard to satisfy the needs at the same time. Therefore, the situation which demand exceeds supply often appears. This thesis builds an allocation model which aims to survive the most amounts for multiple disaster-affected areas and multi-stage post-earthquake rescue resources on the hypothesis that demand exceeds supply, proving the existence and unique of optimal solution. It tests and illustrates the correlation between stages, finally providing specific examples and analyzing the sensitivity of important parameters in the model.Due to the complexity of resource allocation, this thesis only study on a small part of it. There exist some shortcomings. The last part of this thesis is the summary of research, pointing out the possible future orientation in this research field.
