二元不确定语言术语集成算子及在群决策中的应用

摘要

针对基于不确定语言评价信息的群决策问题,本文对不确定语言术语进行拓展,定义了包含语言术语权重信息的二元不确定语言术语,并给出能克服目前不确定语言术语集成运算不足的二元不确定语言术语集成运算法则.在此基础上,提出了基于二元不确定语言术语集成算子的群决策方法,并通过算例说明决策方法的可行性和有效性.%With respect to group decision-making problems based on uncertain linguistic evaluation information,this paper expands uncertain linguistic term and defines binary uncertain linguistic term which contains the weight information of linguistic term.Meanwhile,the operational laws of binary uncertain linguistic term are given to overcome the current blemish of uncertain linguistic term aggregating operation.On this basis,an approach to group decision making problems is proposed based on binary uncertain linguistic term aggregating operators.Finally,an example is given to illustrate the feasibility and effectiveness of this decision-making method.
