Predictive curves

Predictive curves are used to predict the future conditions of your assets based on their present index values. When you define an inspection index, you can enter a formula to determine which predictive curve is used to calculate deterioration for that index. The curve is then used to project the future value of the index in needs analysis runs.

You define the shape of a predictive curve by specifying the X and Y coordinates of a series of points. The X-axis represents time and the Y-axis represents asset condition ratings. Different types of predictive curves have different shapes. For example, one curve might show the condition of assets deteriorating in a straight line. Another might show the condition deteriorating at a rate that increases over time.
