Modeling Aircrafts Operational Reliability
Résumé
The success of an aircraft mission is subject to the fulfillment of
some operational requirements before and during each flight. As these
requirements depend essentially on the aircraft system components and the
mission profile, the effects of failures can be very significant if they are not
anticipated. Hence, one should be able to assess the aircraft operational
reliability with regard to its missions in order to be able to cope with failures.
This paper addresses aircrafts operational reliability modeling to support
maintenance planning during the mission achievement. We develop a modeling
approach to represent the aircraft system operational state taking into account
the mission profile as well as the maintenance facilities available at the flight
stop locations involved in the mission. It is illustrated using Stochastic Activity
Networks (SANs) formalism, based on an aircraft subsystem.
