On competing risk and degradation processes

Lehmann’s ideas on concepts of dependence have had a profound effect on mathematical theory of reliability. The aim of this paper is two-fold. The first is to show how the notion of a “hazard potential” can provide an explanation for the cause of dependence between life-times. The second is to propose a general framework under which two currently discussed issues in reliability and in survival ...

Multi-objective Imperfect Maintenance for Dependent Competing Risk Systems with Multiple Degradation Processes and Random Shocks

Modeling age-based maintenance strategies with minimal repairs for systems subject to competing failure modes due to degradation and shocks

This paper deals with maintenance strategies with minimal repairs for single-unit repairable systems which are subject to competing and dependent failures due to degradation and traumatic shocks. The main aims are to study different approaches for making a minimal repair decision (i.e. time-based or condition-based) which is a possible corrective maintenance action under the occurrence of shock...

A random shock model with mixed effect, including competing soft and sudden failures, and dependence

A system is considered, which is subject to external and possibly fatal shocks, with dependence between the fatality of a shock and the system age. Apart from these shocks, the system suffers from competing soft and sudden failures, where soft failures refer to the reaching of a given threshold for the degradation level, and sudden failures to accidental failures, characterized by a failure rat...
