犹豫模糊环境下基于新型距离公式的三支多属性决策方法
Three-way multi-attribute decision-making method based on a novel distance formula in hesitant fuzzy environments
摘要
Abstract
A novel three-way multi-attribute decision-making method is proposed based on a new distance formula for two hesitant fuzzy elements within the hesitant fuzzy environment.Furthermore,a new relative utility function grounded in regret theory is established and three decision rules are developed for classifying and ranking all alternatives.Finally,a practical case study on stock investment is conducted to validate the feasibility and effectiveness of the proposed method,with comparative analysis and parameter sensitivity analysis further confirming its stability.关键词
