| Abstract | The damage resistance cyber-physical system (CPS) has gained growing attention in research communities. Recent studies typically describe a system's resistance to shock damage using a constant factor ranging from 0 to 1, which may not accurately represent the system's true resistance due to operational intricacies. This paper introduces a resistance function employing a logarithmic form to illustrate the system's dynamic resistance to shock damage. Initially, we present the process of modeling this resistance function and examine its statistical characteristics. Subsequently, we expand upon the three types of non-fatal shocks outlined in previous studies, applying them to a multi-phase context and exploring the impact of each type of non-fatal shock across the system's three degradation phases. Using the proposed resistance function, we formulate an explicit solution for a damage resistance multiphase system reliability model. Finally, numerical examples are provided to show that the reliability model developed offers a good depiction of the system's reliability characteristics.
