Various regulations about urban rail vehicle inspection and repair can ensure the safety of vehicle. This paper proposes an effective calculation method for the contribution rates of regulations based on the decline of the average failure rate. First, the reliability growth mathematical model named AMSAA is introduced. Then the fault time series are used to estimate the model parameters and tests are given to estimate the goodness of fit. According to AMSAA model, the failure rate functions and the average failure rates are calculated. The declines of the average failure rates are used to calculate the contribution rates. Finally, the subway fault time series are used for experimentation. The results show that the method has a high feasibility.
