粗糙集和证据理论对处理不确定信息极具优势,结合二者所长,提出一种融合两种算法的故障诊断方法。首先,通过粗糙集理论对冗余的条件属性进行必要约简,然后对约简后的条件属性计算基本概率赋值和规格化并进行DSmT合成,最后将以上方法应用在关于某型装备故障诊断中验证其有效性。
粗糙集和證據理論對處理不確定信息極具優勢,結閤二者所長,提齣一種融閤兩種算法的故障診斷方法。首先,通過粗糙集理論對冗餘的條件屬性進行必要約簡,然後對約簡後的條件屬性計算基本概率賦值和規格化併進行DSmT閤成,最後將以上方法應用在關于某型裝備故障診斷中驗證其有效性。

Advantages of rough sets theory and evidence theory for processing uncertain information are combined to es-tablish one fusion approach of fault diagnosis based on the rough sets theory and dezert-smarandache theory .Firstly the a-bundant condition attribution is reduced through rough sets theory ,then evidence combining results of each reduced result are calculated through the basic probability assignment and normalized attribution significance .The diagnosis results are com-bined by DSmT combining equation .Finally the above method is applied to some equipment diagnosis to verify its effective-ness .
