Modélisation et évaluation des performances de disponibilité d’un avion dans un contexte opérationnel lors des phases de conception

Abstract : This thesis deals with the modelling and computation of in-service aircraft availability at the preliminary design stage. This problem is crucial for designers because it enables them to evaluate availability indicators in order to improve systems under design and to optimize aircraft support. We formalize the dynamic process of technical incidents and their effects on corrective maintenance in airline’s aircraft operations. In the context of a mission defined by a sequence of flight cycles, standard reliability methods are not computationally conceivable with respect to industrial timing constraints. Based on analytic developments, we introduce a methodology that provides an efficient algorithm for computing bounds for availability indicators. Finally, we show the usefulness of our approach on use-cases inspired by real-world aircraft systems.
