Surplus
We develop unit replacement criteria for each class of vehicle. The replacement methodology includes the following factors:
- Service Life--the amount of time the unit can stay at its current level of service
- Technological Life--the productivity decline compared to a newer design
- Economical Life--the total cost associated with a unit over a period of time as well as the length of time the average unit cost is at a minimum.
We remove units from the fleet that have served their useful life span. Surplus units are traded-in, sold to other governmental agencies, or auctioned.
