本文研究了决策信息以三角模糊数互反判断矩阵形式给出的有限方案决策问题。首先定义了模糊C-OWG(FC-OWG)算子和期望模糊C-OWG(EFC-OWG)算子,并研究了它们的一些性质。基于FC-OWG算子和EFC-OWG算子,提出了方案偏好信息为三角模糊数互反判断矩阵的方案排序方法,根据决策者的偏好程度进行调节,并利用决策者的偏好程度对排序结果进行敏感性分析。实例表明,新方法计算简单、可行且有效。
In this paper, we study the decision-making problem of the finite decision-making given in the form of triangular fuzzy number reciprocal judgment matrix. Firstly, the operator of fuzzy C-OWG (FC-OWG) and the expected fuzzy C-OWG (EFC-OWG) are defined and their properties are studied. Based on the FC-OWG operator and the EFC-OWG operator, a scheme ranking method is proposed, in which the preference information of the triangle is fuzzy triangular reciprocal judgment matrix, adjusted according to the preference degree of the decision maker, and the ranking result of the decision maker Conduct a sensitivity analysis. The examples show that the new method is simple, feasible and effective.
