Evaluation of Urban Flood Disaster Resilience Based on Ordered Weighted Average Operator and Regret Theory
In view of the issue that the evaluation process of urban flood disaster resilience was highly subjective and did not take into account the decision-makers'bounded rationality and regret avoidance psychological behavior,resulting in distortion of evaluation results,an urban flood disaster resilience evaluation method based on the ordered weighted average operator and regret theory was proposed.Firstly,based on the concept of resilient city,an index system was built from the following four dimensions including resistance ability,early warning ability,adaptive ability and resilience ability.On this basis,the order weighted average operator was used to assign the expert extreme decision value to the position with lower weight,and the index weight was obtained by the form of combined weight to weaken the influence of subjective preference extreme evaluation value on weight.Then,considering the psychological and behavioral characteristics of regret during expert deci-sion-making,utility value matrix,regret-joy value matrix and perceived utility matrix was built to obtain the urban flood disaster resilience e-valuation value.Finally,empirical analysis and verification were carried out based on the flood disaster resilience evaluation of Henan Prov-ince,and the calculated results were compared with the results obtained by other evaluation methods to verify the effectiveness of the risk as-sessment method proposed in this paper.The results show that the evaluation results of the four methods are basically consistent,and all of them consider the flood disaster toughness level of Henan Province isⅢ.However,the evaluation results of the method proposed in this pa-per are more accurate and closer to the actual situation.In addition,the results show that the toughness levels of prefecture-level cities are different and unevenly distributed,showing that the toughness levels of southwestern cities are better than those of northeastern cities on the whole.
