Abstract

This article describes the use of industrial maintenance techniques such as improved repair scheduling rules for a finite capacity transit maintenance facility. A 2-tiered maintenance system was simulated to test various scheduling rules. The major parameters of the model were fleet size, spare factor, available labor hours, failure patterns, and repair time distribution. The simulation experiments consisted of a series of comparisons: comparison of scheduling policies; comparison of policy superiority under changing conditions; and comparison of performance indicators under charge labor resource availability. The study findings emphasized the importance of tracking labor times required to repair buses and using labor times to systematically plan and schedule maintenance work with respect to the expected repair times. Trade offs between different maintenance elements are the most important factor of maintenance management decision making. Other study findings are also discussed.
