Research Of Multi-Stage Emergency Materials Allocation Problem Based On Dynamic Demand Of Multi-hit Points

Emergent events happened frequently globally in recent years, especially the natural disasters, causing lots of property loss, ecological environment damage and serious social harms. Emergent events have already endangered public safety. The research of emergency management seems quite important and urgent because of the high frequency and severe harm of emergent events. Emergency materials allocation is an important part of emergency management. Accordingly, the research of emergency materials allocation is pretty significant.This paper bases on the research of National Natural Science Foundation of China, "the research of incomplete extinguished problem by emergent multi-commodity allocation after emergent events". This paper sets the response time as the main parameter of the model, than researches the optimal decision under the condition of dynamic demand of hit point, mainly focuses on the single-stage and multi-stage problems of allocation and distribution of emergent materials.This paper sets different mathematical models based on dynamic demand according to different scenarios respectively:a single rescue point of a variety of emergency materials allocation with the single hit point, single rescue point of a variety of emergency materials allocation with multi-hit points, multiple rescue points of a variety of emergency materials allocation with single hit point, multiple rescue points of single emergency material allocation with multi-hit points, multiple rescue points of a variety of emergency materials allocation with multi-hit points. Frame out the algorithm of the models, than do empirical analysis of the model. Finally, a summary of this study and the research prospects for the future pave the way for further research.
