Z-numbers的综合加权距离度量
Comprehensive weighted distance measure for Z-numbers
摘要
Abstract
The Z-number is a concept proposed by Zadeh for handling information uncertainty and reliability.It includes fuzzy numbers A and B,as well as hidden probability distributions,allowing for simultaneous consideration of the fuzziness and reliability of information,making it suitable for complex decision-making problems.However,existing distance measurement methods for Z-numbers often convert them into classical fuzzy numbers,resulting in some loss of information,particularly the underutilization of information from hidden probability distributions.To address this issue,this paper proposes a new comprehensive weighted distance measurement method that combines Bhattacharyya distance to quantify the differences in hidden probability distributions between Z-numbers.Experimental results indicate that this method can more comprehensively reflect the information within Z-numbers,thereby improve the accuracy of decision-making.关键词
