基于扩展三角方程,定义了一些新的语言变量运算法则。然后将OWA算子扩展到语言环境中,提出了一类新的语言聚合算子:不确定语言有序加权平均(ULOWAf)算子、诱导不确定语言有序加权平均(IULOWAf)算子和不确定语言加权平均(ULWAf)算子。随后研究了扩展算子的一些理想性质,并基于ULWAf和IULOWAf算子提出了一种针对不确定语言环境的实用群体决策方法。给出了一个数值例子来说明财务决策问题的新方法。
Based on the extended triangular conorm, some new operational laws of linguistic variables are defined. Then a class of new linguistic aggregation operators is developed by extending the OWA operator to the linguistic environment, the uncertain linguistic ordered weighted averaging (ULOWAf) operator, the induced uncertain linguistic ordered weighted averaging (IULOWAf) operator and the uncertain linguistic weighted averaging (ULWAf) operator. Later some desirable properties of the extended operators are studied and a practical group decision making methodology for an uncertain linguistic environment is proposed based on the ULWAfand the IULOWAfoperators. A numerical example is given to illustrate the new approach for a financial decision making problem.
