Backlog Projection Model

A scenario of the level of deferred maintenance (DM) resulting from an assumed funding level. An arithmetic equation that calculates future levels of deferred maintenance in light of a given funding level. A form of backlog reduction strategy.

A. Linear Funding Models
This method asks the question: “If the owners fund at level x, what  will be the resultant FCI each year?

B.  Lumpy Funding Models

This method of funding asks the question: "What should our funding be each year to ensure that the FCI remains at a certain level."
