将梯形模糊有序加权平均算子(TFOWA)扩充至诱导的梯形模糊有序加权平均(ITFOWA)算子情形.提出两梯形模糊数接近度概念,用其度量属性本身的重要性程度、并以属性值的接近度作为诱导变量,采用ITFOWA算子进行信息集结,得到一种新的基于诱导梯形模糊有序加权平均算子的多属性决策方法.
This paper contributes to extend the trapezoidal fuzzy ordered weighted averaging operator (TFOWA) to induced trapezoidal fuzzy ordered weighted averaging operator (ITFOWA). An adjacent degree between two trapezoidal fuzzy numbers is introduced on the basis of properties of attribute value, through which we get the induced value of each attribute and then aggregate information. A new multi -attribute decision making model is proposed based on this extended ITFOWA operator.
