立足于任务这个高层次的用户需求,通过对系统持续执行任务能力的参数分析,给出了应用美国工业界武器系统效能委员会(WSEIAC)提出的效能评估方法来分析和评价系统生存能力的方法.在此基础上,针对应用广泛的k/N热备份冗余结构,给出了具体系统生存能力的分析和评估方法.仿真实验表明,该分析方法有助于分析冗余技术对生存能力的影响,以便系统设计者合理应用冗余技术,在有限的资源下尽可能增强系统的生存能力.
Based on the high-level user requirements of mission, this paper gives a method to evaluate and evaluate the viability of the system by using the performance evaluation method proposed by the American Industrial Weapon System Effectiveness Committee (WSEIAC) through the parameter analysis of the system’s ability to continue to perform tasks. On this basis, the analysis and evaluation method of specific system survivability is given for the widely used k / N hot backup redundant architecture.The simulation results show that this method is helpful to analyze the impact of redundancy on survivability , So that system designers can reasonably apply redundant technologies to maximize system survivability with limited resources.
