Abstract

The present paper makes a link between the literature on competing risks and that of opportunistic maintenance. Three models for competing risk involving censoring through opportunistic maintenance are discussed. One is an existing opportunistic maintenance model, one is a new opportunistic variant on an existing competing risk model, and the third is a new model that captures the notion of opportunistic informative maintenance. These models show that even though opportunities may occur according to a process that is independent of the failure process, the appropriate competing risk models may still involve dependencies. This work was motivated by observation of practices in a coal-fired power plant consisting of four generating units, which is briefly described.
