对条件属性值域不完备且决策属性值又是模糊的不完备模糊决策信息系统的研究,至今还不多见。在不完备模糊决策信息系统的粗集模型基础上,提出了启发式约简算法和基于辨识矩阵的约简算法,并通过实例说明了算法的可行性。

Abstract

The concept of incomplete and fuzzy decision information systems based on incomplete approximation space and fuzzy decision information system was proposed recently. Based on the rough set model of incomplete fuzzy decision information systems by the tolerance relation, two reduction algorithms was proposed, and showed they are feasible by example.

Keywords：Rough set，Incomplete information system，Fuzzy decision information system
