Abstract EN
Maintenance has gained a great importance as a support function for ensuring aero engine reliability and availability.
Cost-effectiveness and risk control are two basic criteria for accurate maintenance.
Given that aero engines have much condition monitoring data, this paper presents a new condition-based maintenance decision system that employs data fusion for improving accuracy of reliability evaluation.
Bayesian linear model has been applied, so that the performance degradation evaluation of aero engines could be realized.
A reliability evaluation model has been presented based on gamma process, which achieves the accurate evaluation by information fusion.
In reliability evaluation model, the shape parameter is estimated by the performance degradation evaluation result, and the scale parameter is estimated by failure, inspection, and repair information.
What is more, with such reliability evaluation as input variables and by using particle swarm optimization (PSO), a stochastic optimization of maintenance decision for aircraft engines has been presented, in which the effectiveness and the accuracy are demonstrated by a numerical example.
