基于犹豫度的灾害链应急系统优先权排序研究

摘要

针对属性权重不完全确定的多属性应急群决策问题，给出属性的直觉模糊集，基于犹豫度利用线性规划方法确定多属性应急群决策系统中各属性的最优权重，同时为了解决决策者主观偏好的问题。基于综合直觉模糊集提出了新的决策方法，利用得分值排序法及IFHA算子进行集结，从而减小主观偏好对决策的影响，通过灾害链应急系统中次生灾害点优先权排序的算例，实例分析结果验证了该方法的有效性和可行性。%With respect to the problems of multiple attribute emergency group decision-making in which the attribute weights is incomplete,intuitionistic fuzzy sets of attribute is proposed.Based on the degree of hesitation, by linear programming method,optimal attribute weights for multiple attribute emergency group decision making system can be derived.In order to solve the issue of decision maker’s subjective preference of decision system,a new decision-making method based on the integrated intuitionistic fuzzy sets has been raised,which utilize the score ranking method and the IFHA operator to aggregate,thereby reducing the effect of subjective preference of the deci-sion.Finally,through a priority ranking case of secondary disasters in disaster system and results of the application examples verify the effectiveness and feasibility of the proposed method.
