Because railway locomotives are complex and highly correlated with each other among its components, it is difficult to make Criticality evaluation by using traditional methods. In the present work, a criticality evaluation index model of the locomotive is established and the Monte Carlo simulation method is employed to obtain the criticality priority of the railway locomotive components. Based on the analysis and method, a program for general calculation is developed and applied to the criticality analysis on DF4D locomotive. The case showed that this method is an effective way to evaluate the criticality of the components of the railway locomotive. In addition, the new method of evaluation of criticality is more objective and suitable for practical situations since the analysis, for example, demonstrates that the equipment components with low failure rate have a high criticality priority. Furthermore, the method is convenient by employing Monte Carlo simulation. Therefore, this improved analysis method on the criticality analysis has a practical impact on making decision for the maintenance mode of complex equipment, i.e., railway locomotive.
