基于直觉模糊容差粗糙集的三支决策模型
Three-way Decision Model Based on Intuitionistic Fuzzy Tolerance Rough Sets
摘要
Abstract
In the intuitionistic fuzzy information system,a new intuitionistic fuzzy tolerance degree is defined,a classifica-tion approach for intuitionistic fuzzy tolerance classes is proposed.New formulas for calculating positive and negative devia-tion values are introduced.Based on these,a novel method for calculating conditional probability is developed,leading to the establishment of a three-way decision model based on intuitionistic fuzzy tolerance rough sets.This model is capable of classification,ranking,and selecting the optimal solution.Finally,examples and comparative experiments are provided to verify the feasibility and stability of the model.关键词
