Reliability Evaluation under Shock Model

Abstract

The approximation of reliability value for an engineering system is significant to predicting its possible successful operation. Typically, such approximation is done by taking into account system attributes and, or factors that may influence the operation of the system. An example of such attribute is calendar age while an example of a factor that could influence system operation is shock. This paper investigates the effect of shock on the reliability of a system component and then the system in its entirety. A general shock model is introduced from where the reliability model is developed with the assumption that components and system failure follows the exponential distribution. The developed model is then evaluated on example case studies.
