摘　　要：提出一种基于PC-LINMAP耦合赋权、云理论来判断系统入侵发生可能性大小的新方法。首先运用PC-LINMAP耦合赋权法计算系统主要性能指标的权值,并将得到的权值与理想状态下各个性能指标的数值做加权融合,从而得到理想状态下的综合评价结果。将任意时刻通过加权融合得到的数值与理想状态下得到的综合评价结果相比较得出偏差值,最后基于云理论构造定性评测云发生器并结合偏差的大小对当前入侵发生的可能性进行定性描述。实验结果表明了该方法的有效性。A new decision method to judge the damage degree of system intrusion possibility was proposed, which was based on PC-LINMAP and cloud theory. Firstly, the index of system performance will be given weighted values by using PC-LINMAP Theory, and these computed weighted values will be compared and fused with the values out from index of system performance under ideal conditions, Then this result of comprehensive assessment under ideal conditions could be obtained, Following next, the variation could be obtained by the comparison of real time＇s weighted fusion values with comprehensive assessment under ideal conditions at each specific moment. Finally, the Cloud Generator which is based on Cloud Theory combined with the above variation can achieve the qualitative description about the damage degree of current system intrusion possibility, The result of experiment shows that this method is effective.
