针对工程方案优选中的模糊问题,基于直觉模糊层次分析法,将同时考虑隶属度、非隶属度及犹豫度的区间直觉模糊数引入层次分析法,对工程方案进行优先排序.通过建立层次结构模型,根据影响因素的重要性差异确定直觉模糊判断矩阵,依据决策者权重,计算各方案判断矩阵的熵权,从而得到各方案在不同属性下的最终熵权,并依据大小排序确定最优方案.将该方法应用于工程案例,通过计算和分析证明了本方法在工程方案优选问题中有效性及可行性.%In order to obtain an optimal plan of fuzzy problems in engineering,a new decision method was proposed basing on an intuition fuzzy analytic hierarchy process. This study integrates the interval intuitionistic fuzzy number into the AHP with the con-sideration of subordinate degree,non- subordinate degree and hesitation degree. As a result, the construction plan can be determined according to the priority level. By establishing the hierarchy structure model and determining the intuitionistic fuzzy judgment matrix based on the importance of the influencing factors,the final entropy weights of each scheme with different attributes can be deter-mined by calculating the judgment matrix and considering decision makers' weights. The optimal solution therefore can be obtained by considering entropy weights. The developed method is applied to an engineering case. The results indicate that this method is effective and feasible in engineering plan optimization.
