摘要
既考虑集合的动态特性,又考虑知识库中的统计信息,提出了单向S-概率粗集。讨论了单向S-概率粗集的动态特性,为获得动态的决策规则奠定了基础。给出了单向S-概率粗集的意义解释,单向S-概率粗集是对经典粗集理论和单向S-粗集理论的进一步完善与发展。
Considering dynamic property of the set and statistical informational in knowledge base,this paper puts forward one direction S-probability rough sets.Dynamic properties of one direction S-probability rough sets are discussed, these properties are the bases of dynamic decision-making.The meaning explanation of one direction S-probability rough sets is proposed.One direction S-probability rough sets is a complement to Z.Pawlak rough sets and one direction S-rough sets theory.
