多粒度区间语言信息的C-OWH算子及其应用

摘要

研究了多粒度区间语言信息的集成问题,把连续的有序加权调和( C-OWH)平均算子拓展到多粒度区间语言环境中,提出了连续区间二元语义OWH (ITC-OWH)算子,并在此基础上提出了加权调和的ITC-OWH(WHITC-OWH)算子,有序加权调和的ITC-OWH (OWHITC-OWH)算子以及组合的ITC-OWH(CITC-OWH)算子,探讨了它们的一些性质.最后给出了基于这些算子的多粒度区间语言多属性群决策方法,实例分析结果表明该方法是可行的.%The problem of multi-granularity interval linguistic information aggregation is studied. The continuous ordered weighted harmonic ( C-OWH) averaging operator is extended to accommodate multi-granularity interval linguistic environment. In this paper, we proposea continuous interval two-tuple OWH ( ITC-OWH ) operator. Based on ITC-OWH operator, some new operators are proposed, such as weighted harmonic ITC-0WH( WHITC-OWH)operator, ordered weighted harmonic ITC-OWH(OWHITC-OWH)operator, combined ITC-OWH(CITC-OWH) operator, and we discuss some properties of these operators. Finally an approach for multi-granularity interval linguistic multi-attribute group decision-making is developed based on these operators. The results of an example show that the method proposed in this paper is feasible.
