Interval optimization of civil aircraft imperfect preventive maintenance based on availability
The initial preventive maintenance interval recommended by civil aircraft manufacturers usually does not consider the operators' environment and maintenance capacity difference.It is difficult to achieve the optimal state of availability while meeting the requirements of aircraft safety.Based o...

| description | The initial preventive maintenance interval recommended by civil aircraft manufacturers usually does not consider the operators' environment and maintenance capacity difference.It is difficult to achieve the optimal state of availability while meeting the requirements of aircraft safety.Based on the imperfect maintenance theory, the reliability model of components is modified by the service age fallback factor to reflect the impact of maintenance work on component performance.Combined with the airlines operation reality, taking component availability as the objective function and reliability threshold as the constraint condition, the preventive maintenance interval optimization model in imperfect maintenance strategy is established.An example is given to verify the air starter line fault data of an aircraft.The results show that the optimal maintenance interval obtained by the established maintenance interval optimization model is consistent with the actual situation, and the model is reasonable and feasible. |
