Abstract or Summary
  • Oregon Department of Transportation (ODOT) Fleet Services manages a fleet that in 2008 included approximately 5,000 pieces of active equipment worth $340–$390 million. Every biennium, a fixed budget is available to replace a certain amount of this equipment. This research evaluated various measures for establishing equipment replacement priorities. A model was developed to simulate the operation of a single equipment class over time, including equipment replacement every two years. Five different equipment classes were simulated using ten measures for establishing replacement priorities. Historical data for these five different equipment classes (provided by ODOT) was used to define various simulation parameters. The effectiveness of each prioritization measure was evaluated using the cost per mile to operate the fleet over the simulated time period.
