Dynamic Adjustment Method Of Emergency Rescue Scheme Under Dual Resource Constraints

In recent years,the frequent occurrence of various emergencies has caused a heavy blow to mankind.Its huge destructive power has brought huge losses to the economy and seriously threatened the stability and development of society,which needs the common attention of all mankind.Therefore,in the face of emergencies,it is necessary to quickly carry out emergency rescue to save people’s lives and property,restore the ecological environment and social stability and order,and reduce or eliminate the consequences of emergencies.The emergency rescue process has the characteristics of urgency,complexity and uncertainty.As the guidance and basis of emergency rescue,it is of practical significance to study its dynamic adjustment in highly uncertain environment.Firstly,this paper analyzes the characteristics of emergency rescue and scheme,and defines the process and implementation of emergency rescue.Sort out the dual constraint emergency resources,and describe their attributes and characteristics.Explore the emergency rescue activities,and formally express the resource input mode,activity partial order relationship and dependency relationship.Based on a large number of uncertain factors in the actual environment,the uncertain factors of emergency rescue activities are expressed in the form of fuzzy numbers.The network plan expression of emergency rescue scheme based on AND-OR network diagram is given,and the motivation of emergency rescue scheme adjustment is identified and measured.According to the adjustable object,the adjustment problem is decoupled and divided into two sub problems.Based on the divided subproblems,the adjustment objectives,dual resources,activity constraints and adjustment costs of the emergency rescue plan are summarized,and the dynamic adjustment steps of the emergency plan are given.Secondly,this paper constructs an optimization model of dynamic adjustment of emergency plan composed of fuzzy multi-mode activities.Combined with the actual requirements of the model,according to whether to change the routing structure of the scheme,the sliding window algorithm is designed and the "Genetic-Tabu" algorithm is optimized.Finally,the simulation is carried out by programming,and the results show that the method is feasible and effective.Finally,taking the fire rescue process of a chemical plant as the background,this paper gives an example to realize the mapping between the mathematical model and the example,and explores the dynamic adjustment of the emergency rescue plan in the face of the infeasible scenario caused by abnormal conditions in the emergency rescue process,which verifies the practicability of the model.Based on the dual resource constraints,this paper establishes a universal dynamic adjustment process and optimization model of emergency rescue plan.On the one hand,it provides quantitative support for the dynamic adjustment of fuzzy multi-mode emergency rescue activities under dual resource constraints.On the other hand,it also provides a new idea for improving the response ability of emergency rescue schemes in uncertain environments.
