Continuous Ordered Weighted Harmonic(C-OWH)Averaging Operators for Multi-granularity Interval Linguistic Information and Its Applications
Ligang Zhou · Yunchou yu guanli · 2012
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-OWH(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.
