Large numbers of people stranded, blocked, which are induced by large-scale public emergencies such as SARS, natural disaster, could be significantly harmful to the total production and people’s lives of our country. In the public emergencies, it is crucial to ensure the life safty of people, which needs food supply to be guaranteed during such event. Therefore, the food emergency logistics is the most important essential during the whole emergency logistics activities. In order to make sure that the food emergency logistics system could be operated well, it is necessary to supervise, evaluate and optimize the food emergency logistics. The study mainly concerned whether all sectors of emergency logistics could operate effectively, and whether there were bttlenecks or short board in these sectors.On the basis of surveys, this dissertation evaluated the emergency response capabilities of food supply in emergency, optimized current operation process and the cost of food emergency logistics, detailed studies are listed as follows:(1) This dissertation stated the concept, stage division, key workflow of food emergency logistics, improved the current food emergency logistics processes, especially the process of emergency response phase, summarized the food emergency logistics operation flow chart, obtained the optimized operation processes, and evalutaed the effect of its optimization by applying the AHP.(2) This dissertation Combined the characteristics of food emergency logistics, proposed the concepts about emergency response capabilities and evaluation of food supply, described the design principles of evaluation index system based on process management, effectively formulated the evaluation index system by applying hierarchy entropy analysis, and constructed the evaluation model of emergency response capabilities of food supply based on risk analyses. Then the model was proved by an example.(3) According to the reality, this dissertation proposed some reasonable assumptions about resource allocation problems of food emergency logistics, established the resource allocation optimization model, and solved the model by applying genetic algorithms.It gave an example to prove the model.(4) This dissertation constructed the stochastic process model of emergency food in-time transportation by applying the stochastic process theory, obtained the mean continued time of emergency food transportation, which ensures reasonable fulfillment of food emergency logistics demand of time limit of transportation, and found the key and concerned the new method of improving the delivery process of emergency food.(5) Based on previous analysis on operation processes of food emergency logistics, this dissertation propsed the new idea, and formed the optimization model which proved by data obtained from field research.
