The hazard resistance slope is adopted to reflect the ability of the system to resist disruptive events . The secondary hazard occurs at 𝑇 1 , then, the hazard resistance slope decreases and the system performance deteriorate faster. In the post-event degraded phase (𝑇 ∈ (𝑇 2 , 𝑇 3 ]), the system performance is stable, and no subsequent hazards occur. In the restoration phase (𝑇 ∈ (𝑇 3 , 𝑇 𝐸 ]), the recovery process of CPI starts acting, triggering equipment-specific activities and conventional recovery. With the restoration of damaged components, the performance level of CPI will re-enter the safe zone.
