Abstract :
This paper considers a system with imperfect maintenance, ie, after maintenance the system may be either a) not changed, or b) failed, with certain probabilities. Formulas for the MTTF and the availability are obtained and the policy to maximize availability is derived. A numerical example applies these results to a triple redundant system.
