针对准则权重不完全的犹豫模糊多准则决策问题,提出基于区间梯形二型犹豫模糊数的决策方法.首先,给出区间梯形二型犹豫模糊数,根据几何面积法定义区间梯形二型犹豫模糊数的可能度和差异度;然后,利用差异度和离差最大化模型得到各准则权重,基于TOPSIS思想得到各方案的综合贴近度,并对方案进行排序;最后,通过算例分析和对比分析验证了所提出方法的可行性和有效性.
Aiming at the problem of indefinite hegemonic fuzzy multi-criteria decision making problem, a decision-making method based on interval trapezoid type II hesitating fuzzy numbers is proposed. Firstly, the interval trapezoidal two-type hesitating fuzzy numbers are given. According to the geometric area method, Then, the weights of each criterion are obtained by using the model of difference degree and dispersion maximization, the comprehensive closeness of each scheme is obtained based on TOPSIS, and the schemes are sorted. Finally, by the example analysis and comparative analysis The feasibility and effectiveness of the proposed method.
