In recent years improvement of maintenance performance has been the focus of significant concern in the transit industry. Many transit agencies have been plagued with deteriorating vehicle reliability and availability. Even more transit agencies are facing continual increases in maintenance expenditures at a time when total operating budgets are constrained or even diminishing. These trends have moved transit maintenance from the backroom to the executive suite where maintenance performance and expenditures are coming under increased management scrutiny. Maintenance managers need effective, yet straightforward methods for assessing and evaluating the extent to which scarce resources are expended in a productive manner. Resource utilization should be directed toward completion of specific tasks that result in achievement of established performance objectives. Although maintenance is recognized as a complex function, there are some relatively uncomplicated methods for determining the extent to which resources are expended productively. One such methodology is presented and its application at two transit properties is discussed.
