Reliability Modeling of Dependent Competitive Failure with Continuous Degradation and Random Shocks
Based on the reliability analysis of correlated competitive risk systems with degradation processes and stochastic shocks, a dependent competitive failure model considering time-varying soft failure threshold is proposed The failure process includes soft failure caused by continuous degradation and hard failure caused by random impact. In complex equipment, when the system degrades faster due to performance degradation, the soft failure threshold of the system will decrease with the degradation of system performance. In this study, a time-varying soft failure threshold dependent competitive failure model is proposed. Through the numerical analysis of a micromotor, the reliability of the system is overestimated to a certain extent by comparing the models without considering the change of soft failure threshold.
