GRA and GRI imperfect maintenance models: new results
Résumé
At MMR 2015 [5], we presented a first attempt to develop imperfect maintenance models based on Geometric Reduction of Age (GRA) and Geometric Reduction of Intensity (GRI). The development of these models and other geometric reduction models are presented here. Their behavior is illustrated based on simulated data and they are applied to sets of maintenance data obtained from the field.
