Study On The Scale And Layout Of Emergency Relief Materials In Cities

Emergency management of urban emergencies is the basic work of modern urban management.Urban emergency plans and disaster mitigation measures have become an important entry point for government agencies in various cities to control the security of their jurisdictions,and play a huge positive role in ensuring the safe operation of cities.This article research based on the concept of emergency management,vulnerability,and the theory of welfare economics,emergency measures to address the selected theory,combined with literature research,investigation,analysis,influence factor analysis,welfare economics,operational research and econometric methods,such as for emergency and disaster mitigation in the process of modern urban construction work study,including coverage of the disaster relief material and the optimization of storage size,the location of the urban emergency shelter area,the construction of emergency relief measures,etc.The first chapter mainly introduces the research background and significance of the thesis,the research status at home and abroad,research methods,research framework and research ideas.The second chapter,based on all kinds of reference to carry out the principles of urban emergency management,vulnerability,welfare economics theory,modern urban emergency shelter implementation work site selection of the data collecting and combing,and all aspects of the above theoretical concepts and the connection between the modern theory of city emergency relief supplies store,and use this as the theoretical basis of this writing.The third chapter,the impact on city emergency supplies security of sudden events is to cause the fragility of the external causes and conditions.For emergency affecting the safety of supplies usually can only through the study of the regulation of emergency supplies market from "normal" state to state "disruption" to switch,was able to fully expose mechanism of urban emergency supplies for when dealing with the city emergency sensitivity,vulnerability and city supplies the emergency response capacity.The prediction of the casualties in the earthquake disaster when using BP neural network,in 1970 after the 16 earthquake China data based on the results showed little difference in the nature of the output of the network and the sample results,which shows that the method is applied to predict the number of casualties can also be used in the earthquake.In the prediction of casualties,constructed on the basis of material demand model.Then build a prediction model of case based reasoning based on the demand of emergency supplies,identified three items demand for meals,clothes,engineering equipment,taking the Wenchuan earthquake as an example,calculates the corresponding material demand.The fourth chapter,in order to satisfy the optimal allocation of storage resources to emergency function into full play,this chapter is to select the emergency material storage address problems are studied,namely from the aspects of quantity and space optimization of storage resources.First,put forward emergency relief supplies store location target,which meet the shortest response time,to be able to cover all the needs of the region,can effectively solve the "failure" problem in coverage area.finally selected in benxi,zhengzhou city,zhoushan city,quanzhou city,Harbin city,yueyang city,zhuzhou city,nanchang,wuhan,guangzhou,liuzhou,chengdu,chongqing,xuzhou,zhenjiang,changchun city,rizhao city and qinhuangdao city set up reserve base,the base number is 18.The fifth chapter.through to the city's emergency relief materials reserve comprehensively weigh the costs and benefits,and based on the regional cities,according to the size of the emergency relief materials reserve has carried on the optimization research.The article is based on city emergency relief supplies store related influence factors of scale,starvation welfare economics concepts and the analysis of the costs and benefits,in order to maximize the net income of as the optimization goal of city emergency relief material storage size,build optimized decision-making model of urban emergency supplies storage size,by decision model is found city emergency material storage revenue occurs as the biggest in emergency supplies store the marginal revenue and marginal cost at the same time,the scale of emergency supplies store is optimal.Then,based on the demand of emergency supplies function,storage costs and benefits,supply disruptions parameters such as the size of the average of domestic urban emergency relief supplies and then estimated the optimal storage size.Finally.based on the research conclusion and research innovations of emergency relief materials storage area city in the future research emphasis,including the safety emergency supplies and emergency early warning research,modem urban emergency relief materials storage and release strategy research,urban emergency supplies supply vulnerability deep going research,on the basis of "situation and response" city emergency response plan,emergency and disaster mitigation in the study of material selection and optimization of research on the mode of transportation,on the basis of the supply chain to carry out emergency relief supplies store replacement strategy research.
