Three-Way Decisions-Based Conflict Analysis Models
Guangming Lang
Three-way decision theory, which trisects the universe with less risks or costs, is considered as a powerful mathematical tool for handling uncertainty in incomplete and imprecise…
Incremental approaches to updating attribute reducts when refining and coarsening coverings
Mingjie Cai, Guangming Lang
In a dynamic environment, knowledge reduction of information systems with variations of object sets, attribute sets and attribute values is an important topic of rough set theory,…
Related families-based attribute reduction of dynamic covering information systems with variations of object sets
Guangming Lang
In practice, there are many dynamic covering decision information systems, and knowledge reduction of dynamic covering decision information systems is a significant challenge of co…
Related family-based attribute reduction of covering information systems when varying attribute sets
Guangming Lang
In practical situations, there are many dynamic covering information systems with variations of attributes, but there are few studies on related family-based attribute reduction of…
Conflict Analysis for Pythagorean Fuzzy Information Systems with Group Decision Making
Guangming Lang
Pythagorean fuzzy sets provide stronger ability than intuitionistic fuzzy sets to model uncertainty information and knowledge, but little effort has been paid to conflict analysis…
Comments on "Characteristic matrix of covering and its application to Boolean matrix decomposition[Information Sciences 263(1), 186-197, 2014]"
Guangming Lang
In this note, we show some improvements for Theorem 7 and Example 8 in Shiping Wang[Information Sciences 263(1), 186-197, 2014]. Concretely, we study further the sixth lower and up…
