针对区间直觉模糊信息环境下属性权重未知的多属性决策问题,提出了一种新的决策方法.在回顾相关基础理论知识基础上,定义了区间直觉模糊数的得分函数与精确度函数,提出了基于离差最大化的属性权重确定方法,然后基于区间直觉模糊加权平均算子给出了属性权重未知情形下属性信息为区间直觉模糊数的多属性决策方法.最后将该方法运用到突发事件应急预案有效性评价问题,通过实例分析验证了该方法的有效性.
Aiming at the multi-attribute decision making problem with unknown attribute weight under interval intuitionistic fuzzy information environment, a new decision making method is proposed. On the basis of reviewing relevant basic theoretical knowledge, the scoring function and precision function of interval intuitionistic fuzzy number are defined, and the method of determining attribute weight based on maximizing deviation is proposed. Then, a multi-attribute decision making method with interval intuitionistic fuzzy information based on the interval intuitionistic fuzzy weighted averaging operator is proposed. Finally, the method is applied to the evaluation of the effectiveness of emergency plans and its effectiveness is illustrated by a numerical example.
