Abstract
A method and system forecasting maintenance operations to be applied to an engine or a part of the engine including a set of components, the system including: a processor building a lifetime model for each component of the set of components; a processor analysing the lifetime model associated with each component to build a set of failure models corresponding to the set of components, each component being associated with a failure model defining an inter-inspection interval reflecting an advanced degradation risk rate lower than a predetermined safety threshold; a processor defining a maintenance strategy including opportunistic inspections on the set of components; and a processor iteratively simulating maintenance actions on the set of components by using the set of failure models and the maintenance strategy to build a global model of relaxed maintenance operations which takes the opportunistic inspections into account while fulfilling a predetermined safety threshold of each component.
