摘　　要：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。The multi-attribute decision making problem is studied in this paper,in which the information on alternatives preference is given in the forms of triangular fuzzy reciprocal judgment matrix.Firstly,we introduce the fuzzy C-OWG（FC-OWG） operator,and the expected fuzzy C-OWG（EFC-OWG） operator,and study some of its characteristics.Based on these operators,we develop a new method for priority of triangular fuzzy number reciprocal judgment matrix,which is adjusted according to decision-maker＇s preference degree.The method to make sensitivity analysis for the results by decision-maker＇s preference degree is proposed.A numerical example shows the new method is easier to calculate,feasible and effective.
