A Comprehensive Analysis Method for System Resilience Considering Plasticity

Resilience is generally described as the ability of a system to absorb disturbance and to recover rapidly back to its original state. However, the system may not recover thoroughly after every interruption. This paper defines resilient limit and system plasticity, and proposes an analysis method for system resilience considering plasticity, which provides a comprehensive evaluation for both resilience and plasticity of systems suffering from performance degradation. The resilience and plasticity of an airborne GPS/INS navigation system is then analyzed to illustrate the effectiveness of our method.
