摘　　要：针对网络存储系统可生存性评价的局限性,提出一种网络存储系统可生存性定量评估方法。对灰色关联分析法进行改进,建立基于信息熵差的灰色关联分析法的定量评价模型,运用熵差计算出各关键服务的生存性态势变化。利用搭建的典型网络存储环境进行测试,结果表明,基于信息熵差的灰色关联定量分析方法对于网络存储系统的可生存性评价是准确、有效的。Through the limitations of current evaluation about the network storage system survivability, a quantitative evaluation method based on grey relation analysis is proposed. The typical gray relation analysis method is improved and the quantitative evaluation model based on the network entropy of information is established. The change of every key service＇s survivability situation is assessed by using the network entropy of information. The established network storage system is run to test method of grey relation analysis, and the calculating result indicates that the proposed method can effectively evaluate the actual survivability of the network storage system.
