Regret-based three-way decision making with possibility dominance and SPA theory in incomplete information system
作者：
Highlights：
• Introducing a novel uncertainty, namely, interval-valued Fermatean connection number.
• Developing a new approach to derive fuzzy state set and conditional probability.
• Calculating relative utility functions by using regret theory.
• Proposing a novel three-way multi-attribute decision making model.
