52 Life Cycle Cost Analysis LCCA is used in many asset management applications, including pavements, bridges, culverts, buildings, and other assets. For highway operations equipment, LCCA is used to determine optimal life cycles and to analyze the cost history of individual equipment units.

From page 53... ...
53 agencies do not have complete annual cost data for all equipment units. The unit-level LCCA looks at a single piece of equipment and analyzes life cycle cost based on annual cost and utilization data.

54 optimization tool is designed to develop a trend line to model the total cost curve that is used to determine the optimal life cycle (7 years in this case)
|
From page 55... ...
55 LCCA is preset to predict a 25-year cost trend regardless of the age of the equipment. In this example, only 15 years of data are available; the trend for the entire 25 years is projected.

From page 56... ...
56 example would be a bridge snooper truck; an agency might only have one or two units in the fleet: one may be 2 years old and the other 12 years old. A meaningful class-level LCCA cannot be performed with such a low number of units with disparate ages.
