The resilience of critical infrastructures has become a major concern throughout the design, operation, and maintenance process in recent years. While traditional evaluation measures are mainly concerned with complete and timely restoration, this work considers simultaneously the cases where systems fail to recover thoroughly or timely. We define resilient limit and propose a new resilience evaluation...
Resilience test and evaluation is an important technology to evaluate system resilience and verify whether the value of system resilience meets the designated requirements before the system is used. In this study, a resilience test and evaluation process is proposed for given disturbances. The system resilience is defined by the ratio of the integral of the normalized system performance within its...
This paper proposes a quantitative method to evaluate system resilience. By dividing objects into system level and component level, we present two system resilience indexes (ER and p) based on minimal cut-set and its calculation method under continuous disruptive events, considering the influence of component and system structure on system resilience. In addition, the sensitivities of components to...
Resilience is the ability characterizing an engineering system to recover rapidly after disruptions from inside or outside the system. Resilience is realized on the basis of fixed strategies and resources, beyond which the resilience is changing in essence. This paper proposes the definition of system resilience limit, as well as the definition of system resilience concerned with resilience limit...
In the design and allocation of resilience for complex networks, both the resilient characteristics and the locations of constituent components can affect the overall resilience of networks on different levels. Based on the concepts of resilience, this paper proposes the definitions of structure importance, redundancy importance and reinforcement importance, with comprehensive consideration of performance...
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...
