Abstract:

In order to improve the quality of rescue for injured people after earthquakes, starting from the matching problem between emergency rescue personnel and injured victims, focusing on the transportation and evacuation process of the injured, the process of decision-makers formulating matching plans for rescue personnel and victims was transformed into a one-to-many perfect matching problem, and a decision-making model was constructed to solve the optimal matching plan. Firstly, the matching influencing factors were analyzed from two aspects: the emergency environment and the needs of both parties. A scientific and reliable matching indicator system was designed, and information from both parties was collected based on matching indicators. Then, triangular fuzzy numbers were used to quantify the information of both parties. Characterized the perceived utility of decision makers on matching results based on regret theory. A bilateral matching decision model was established with the goal of maximizing perceived utility, and a genetic algorithm was used to solve the problem. Finally, a "9·5" Luding earthquake case was introduced to verify the effectiveness of the model and algorithm. The results show that the bilateral matching decision model based on regret theory can achieve the maximum goal of decision-maker's perceived utility, and the decision results meet the needs of rescue personnel and injured victims. It can effectively avoid matching schemes with low matching degrees between both parties, and improve the quality of earthquake emergency rescue.
