| Abstract: | The effect of maintenance would influence the operating reliability and maintenance costs of vehicles. Based on field data and using change point analysis method, this paper analyzes the change in failure rate before and after automotive type- Ⅱ and type- Ⅲ preventive maintenance （PM）, and evaluates the effect of different types of PM. The method is useful for evaluating and improving the maintenance quality. |
