| 摘 要： | 对于证据理论中不同来源的证据具有不同的重要性，在证据理论中需要应用证据权以提高融合精度。根据粗集理论和证据理论的基本关系，提出了一种基于粗集理论的加权证据多源信息融合方法。将此方法应用到舰船水消防系统生命力评估中，并对其实例进行验证，表明该方法能有效提高融合结果的准确性，并且融合过程更有逻辑性，为舰艇水消防系统设计提供了新的评估方法。

| Abstract: | Since the multiple evidences from different sources have different significances，the concept of evidence weight is introduced to improve the precision of data fusion． Based on the essential relation between the rough set theory and the evidence theory ，a new method with the weighted D-S evidence combined is proposed．The instance of survivability assessment on the water fire fighting system of warships is used to validate the proposed method．It is shown that the method can improve the precision of fusion result and make the process of fusion in a more logical manner．It provides a new way to assess the design of the water fire fighting system of warships． |
