为了研究区间模糊偏好关系的乘性一致性问题,本文首先分析了已有一致性概念的局限性。因此,定义了一个新的一致性概念,它是脆情况的扩展,并克服了以前概念的局限性。其次,构造了判断IFPR一致性的线性规划模型,并给出了求乘性一致IFPR的方法。此外,目标规划模型,以确定缺失值在一个不完整的IFPR构建具有最高的一致性水平,相对于已知的值。此外,一个乘一致性和共识为基础的群体决策与IFPR的方法,可以解决不完整和不一致的情况下。最后,通过两个实际的决策问题验证了该方法的可行性和有效性,并与几种相关方法进行了数值分析和理论比较.
To examine the multiplicative consistency of interval fuzzy preference relations (IFPRs), this paper first analyzes the limitations associated with the previous consistency concepts. Accordingly, a new consistency concept is defined that is an extension of the crisp case and overcomes limitations in the previous concepts. Next, a linear programming model to judge the consistency of IFPRs is constructed, and an approach to derive multiplicative consistent IFPRs is introduced. Furthermore, goal-programming models to determine missing values in an incomplete IFPR are constructed that have the highest consistent level with respect to known values. Moreover, a multiplicative consistency and consensus based method for group decision making with IFPRs is developed that can address incomplete and inconsistent cases. Finally, two practical decision-making problems are offered to demonstrate the feasibility and efficiency of the new method, and an analysis of a numerical and theoretical comparison with several related methods is performed.
