摘　　要：决策形式背景是形式背景的重要扩展。属性约简是决策形式背景领域研究的热点问题。由现实数据所构建的决策形式背景通常是不一致的,文中面向实际应用,研究一般决策形式背景的广义属性约简方法。定义了一般决策形式背景的广义属性约简,并基于辨识函数给出了计算所有约简的算法。该算法具有良好的通用性,可应用于一致和不一致的决策形式背景。Decision formal contexts were a significant extension of formal contexts and attribute reduction was a hot issue in the field of decision formal contexts.The decision formal contexts formed by the real world data were usually inconsistent.Oriented on the practical application requirements,the approach of attribute reduction in general decision formal contexts was studied.Furthermore,the definition attribute reduction of general decision formal contexts was proposed.Based on the discernibility function,the corresponding algorithm of finding all the reducts was given.The proposed algorithm had good generality and could be used in the consistent and inconsistent decision formal contexts.
