摘要 本文在相关文献的基础上研究了不一致决策系统中绝对约简、各种相对约简之间的关系,包括相对于个体的约简和相对于整个决策系统的约简.证明了μ-决策约简等价于信息论意义下的相对约简. In this paper we investigate relations among absolute reduction and relative reductions,including reductions corresponding to objects and reductions corresponding to decision systems in inconsistent decision systems. Furthermore, we prove that μ- decision reduct is equal to relative reduct in the view of information theory.
