摘　　要：深入分析了可生存性的内涵,针对系统在失效环境下的动态行为,从基本服务和及时性两个角度出发,考虑失效及其失效损失,定量地评价系统的可生存性.所建立的模型采用安全性数据集进行了验证,结果表明提出的瞬态可生存性评估模型是有效的.There has been a lot of work conducted over survivability,but a very small portion relates to survivability evaluation,among which very relates to quantitative evaluation.A transient survivability evaluation model is proposed.The nature of survivability is analyzed.Targeted to the dynamic behavior of system under failure environment,failure and loss due to failure are considered from the perspective of essential service and timeliness,and the quantitative evaluation of survivability is given.The accuracy of the proposed transient survivability evaluation model is validated based on a safety dataset.
