Creating a Decision-Making Program for the Decline Period of Emergency Events

Abstract

Based on the analysis of the life cycle theory of emergencies, an emergency decision-making method basedon linguistic information and ordering organization is proposed to solve the problem of emergency plan selection duringthe decline period of emergencies. Firstly, language decision theory is introduced to determine the relative importance ofdecision members and the weight of key indicators. Secondly, the extended weighted average operator is used to aggregatethe preference information of alternative solutions and the relative importance of decision members. On this basis, theranking organization method is introduced to deal with the complex relationship between different key indicators andalternative solutions. Finally, the net flow of each alternative is ranked to determine the optimal one. The feasibility andeffectiveness of this method are verified by taking the operation recovery after a fire in a logistics park as an example.
