摘要
针对犹豫语言决策问题,提出了基于区间梯形二型犹豫模糊数的多准则决策方法。首先,给出了区间梯形二型模糊数的定义。然后,构建了区间梯形二型犹豫模糊数的期望值和贴近度函数。在此基础上,建立了区间梯形二型犹豫模糊数的排序模型,并提出了基于该排序模型的区间梯形二型犹豫模糊多准则决策方法。最后,通过工程决策实例论证了该方法的有效性和可行性。
For decision-making problem with hesitant linguistic fuzzy information, a multi-criteria decision-makingmethod based on interval type-2 hesitant fuzzy number is suggested in this paper. Firstly, the concept of intervaltype-2 trapezoidal hesitant fuzzy number is proposed. Then, this paper defines the expected value and closenessfunction of interval type-2 trapezoidal hesitant fuzzy number, and based on which a method for ranking intervaltype-2 trapezoidal hesitant fuzzy set is presented. We also propose a new multi-criteria decision-making methodbased on the proposed ranking method. Finally, a numerical example of engineering decision-making is given toillustrate the effectiveness and feasibility of this method.
