Projection Group Decision-making Model of Water Conservancy Project Emergency Plans Based on Interval Intuitionistic Fuzzy Information

为了更准确高效地处理应急方案群体决策问题,考虑集结算子集结含零值的决策信息会得到不准确的结果,提出基于区间直觉模糊信息和投影法的应急方案群决策模型。首先,由区间直觉模糊集理论和投影法,构建多目标优化模型求解群体最优集结信息;然后采用区间直觉模糊熵确定指标的属性权重,使用基于方案投影的贴近度确定最优方案;最后通过案例分析,验证该决策模型的有效性。研究结果表明:灾害社会影响和善后处理对应急决策起到了重要作用;投影决策模型提高了决策过程的准确性和效率性,具有较好的适用性和推广性。

To deal with the group decision-making of emergency plans more accurately and efficiently,this paper proposes a group decision-making model of emergency plans based on interval intuitionistic fuzzy information and projection method,since the decision information with zero value in the aggregation operators will get inaccurate results.First,the interval intuitionistic fuzzy set theory and projection method are utilized to build a multi-objective optimization model to solve the optimal aggregation information of the group.Then,the interval intuitionistic fuzzy entropy is adopted to determine the attribute weight of the index,and the closeness based on the project projection is employed to determine the optimal plan.Finally,the effectiveness of the decision-making model is verified by case analysis.The research results show that the social impact of disasters and the aftermath treatment play an important role in emergency decision-making;the projection decision-making model improves the accuracy and efficiency of the decision-making process and has good applicability and generalization.
