RAMS and Maintenance cost assessment in a Multidisciplinary Design Optimization environment

Kurzfassung

Several research studies deal with the estimation of reliability and maintenance cost of the aircraft. However, detailed estimations at subsystem level and assessment on the impact that maintenance man-hour have on maintenance costs have been omitted so far. The purpose of this master thesis is to provide a methodology that estimates RAMS and maintenance costs of a civil aircraft, both at system and subsystem level, at the early design phase in case of conventional and of new generation aircraft.
