报告摘要：Three-way decisions, as a decision-making tool with strong generality and applicability that effectively handles imprecise and uncertain information, have become a core method and mathematical model for analyzing and solving complex decision problems. In recent years, three-way decisions have achieved rapid development both in practical applications and theoretical research. In particular, as a uniquely valuable ramification of three-way decisions, three-way decision spaces have become one of the hot topics in current research. At present, research on three-way decision spaces mainly focuses on two aspects: 1) the transformation methods from semi-three-way decision spaces to three-way decision spaces based on common aggregation functions; 2) the construction methods of (semi-)three-way decision spaces based on fuzzy sets and their derived sets. However, the existing transformation methods from semi-three-way decision spaces to three-way decision spaces and construction methods of (semi-)three-way decision spaces are relatively single in form. On the other hand, the effectiveness of the theories related to three-way decision spaces has not been verified on complex datasets either. Based on this, compared with the existing methods, this talk gives a novel form of transformation methods with a parameter from semi-three-way decision spaces to three-way decision spaces based on aggregation functions, and conducts extended research around the research hot topics of three-way decision spaces. Meanwhile, the methods proposed in this talk are tested on complex datasets.
