【摘要】 相对其他决策系统,不一致不完备决策系统对于复杂数据具有更强的数据建模和表示能力,这决定了其在实际应用中的重要作用.鉴于此,在已有研究成果的基础上深入探讨了不一致不完备决策系统中约简的定义方法,提出了不一致不完备决策系统中的5种约简概念,并找出了它们之间的关联,为进一步研究此类系统中知识约简的理论和方法奠定了基础.更多还原

【Abstract】 Inconsistent incomplete decision system(ⅡDS)has strong superiority in modeling and expressing complex data compared with other decision systems,which shows its important value.Therefore,based on existed research results,this paper investigates the definition method of reduction inⅡDS.Five kinds of reduction in IIDS,such as possible reduct,are presented and the relationships between them are also found out.This work can form the foundation for further studying related theory and method of reduction inⅡDS.更多还原
