| Abstract: | This paper deals with consistent decision formal context and the attribute reduction in it.A relation based on formal context is defined here.In addition,this paper proposes theory of knowledge reduction based on consistent decision formal context and gives the judgement theorems and discernibility matrices,from which methods of attribute reduction in consistent decision formal context can be derived. |

| Keywords: | consistent decision formal context decision consistent set decision attribute reduction discernibility matrices |
