Survivability analysis and evaluation for redundant system

Based on the tasks,the high-level user requirement,and by analyzing the parameter of the continued ability to carry out its tasks,the method of the analysis and evaluation of system survivability based on weapon system effectiveness industry advisory committee(WSEIAC)is presented.Based on this method hot standby redundant structure(k-out-of-N system)can be analyzed and evaluated in detail.The simulation shows that the analysis method is useful for system designers to make reasonable use of redundancy technology,and can improve the system survivability with limited resources.
