Abstract : A composite measure comprising linear combination of reliability, availability, and maintainability (CMRAM) is proposed for an intermittently-used complex repairable system, namely a transport helicopter. The failure data are fitted in Weibull distribution for overlapping intervals of operating time to capture the effect of recent maintenance and other actions. Evaluation of CMRAM is helpful in formulating future operational and maintenance strategies.
