Abstract:

A vehicle reliability methodology to aid in the determination of an operating service policy or maintenance schedule for a light rail transit system is presented. A decision-theoretic approach is developed to balance the costs of troubleshooting and regular maintenance against the risks of breakdown, repair and passenger delay. The reliability of a vehicle is compared with a critical vehicle reliability obtained from the decision-theoretic approach to determine the suitability of a vehicle for service or to determine the optimal scheduling of the next regular maintenance to minimize expected cost. This expected cost includes the cost of passenger delay in addition to operating and maintenace costs. To provide an example of how the methodology is used, reliability distributions were fitted to the miles between discrepancies for the propulsion, electrical, brake, and door subsystems based on data from the Massachusetts Bay Transportation Authority. Flexibility in applying the technique is illustrated in a sensitivity analysis. Changes in the decision process are shown with respect to changes in five key parameters. (Author)
