摘要
定义了区间灰色不确定语言及其运算法则和距离公式。拓展了连续区间数据的OWA(C-OWA)算子,提出了基于区间灰色不确定语言的有序加权C-OWA(IGULOWC-OWA)算子,并对其性质进行了分析。针对准则权重已知而方案的准则值为区间灰色不确定语言的多准则决策问题,提出了一种基于IGULOWC-OWA算子的多准则决策方法。该方法通过对各方案在各个准则下的评价值进行转换,将区间灰色不确定语言转化为不确定语言,然后,利用集结算子计算出各个方案的综合准则值,进而得出各方案的排序。最后通过算例表明了方法的可行性和有效性。
In this paper,interval grey uncertain linguistic,as well as its operation principles and distance formula,is defined.As an extended continuous interval argument OWA（C-OWA） operator,interval grey uncertain linguistic ordered weighted C-OWA（IGULOWC-OWA） operator is presented,and its characteristics are discussed.As for the multi-criteria decision making problems,in which the criteria weights are completely known and the criteria values of alternatives are in the form of interval grey uncertain linguistic,a multi-criteria decision approach based on the IGULOWC-OWA operator is proposed.In the method,the criteria values of alternatives are converted into uncertain linguistics.Then,the collective values of alternatives can be obtained by using the aggregation operator.Finally,an example is given to illustrate the feasibility and validity of the developed method.
