Complex systems are usually repairable and subject to a few types of different preventive maintenance (including overhaul), which can be imperfect. This paper reanalyzes the bus-motor-failure data of [1]. Four different competing risk models, each of which has three parameters, are fitted to the data and the best model is identified. Based on an examination of the failure rate of the fitted model, two basic aging characteristics are identified and analyzed. The results are useful for modeling and analyzing similar systems.
