摘要
三支决策是由Yao等人基于决策粗糙集理论模型,进一步结合决策情景而提出的一种决策理论。它成功地为粗糙集的正域、负域和边界域合理地赋予了语义解释,分别对应实际决策中的接受、拒绝和延迟决策。三支决策理论自提出以来,随即得到诸多学者关注并对其进行了完善和拓展,其已在多领域得到广泛应用。详细介绍三支决策的背景及基本理论模型,总结国内外关于三支决策的研究现状及进展,最后对三支决策未来研究方向进行了展望。
Based on decision-theoretic rough sets and practical situation,the concept of three-way decisions is a kind of decision theory proposed by Yao et al.With the aid of this theory,the positive,negative and boundary regions of rough sets are given a new semantic explanation,which correspond to the notions of acceptance,rejection and deferment in decision making,respectively.Since the raise of three-way decisions,it has attracted many scholars’attentions and it is improved and expanded to many fields.In this paper,we firstly introduce the background and basic theoretical models of the three-way decisions.Then,we can review the current research status and progress of this topic.Finally,we look forward to the future research trends.
