摘要:: 采用层次化结构设计了一种新的系统状态分析模型，该模型可以用来量化信息系统的生存性。将系统定义为一种以服务为中心的层次结构，将生存性测试划分为防护能力、检测能力和恢复能力三级。并在层次化模型基础上计算了系统的生存性。通过一个案例，说明了层次化系统生存性计算方法不仅可以有效避免对系统的状态进行直接定义和分析，而且使系统生存性分析支持实际操作及程序化

Abstract:: A new system state analysis model with hierarchical structure is designed,the model can be used to quantify the survival of the information system. The system is defined as a service-centric hierarchy based on three levels of protection,detection capability and the a-bility to recover to achieve survival test. The survival of the system is calculated by the system definition and system survivability test lay-er by layer. The case study shows that survival-based hierarchical system computing method can avoid direct state definition and analysis, and make the system survival analysis practical and programmable
