referred to as the "funding-life cycle matrix".
A matrix that plots the relationship (correlation) between the age of a facility and its capital reinvestment requirements, presented on a scatter plot.
The primary purpose of the age-reinvestment correlation is as follows:
The age-reinvestment matrix is comprised of two dimensions, as follows:
The horizontal (x axis) is comprised of the following age classes derived from the facility lifecycle model:
Two alternative measures can be used to quantify the funding requirements on the vertical axis:
reinvestment formulas have been applied to establish the quantum and reinvestment rates and funding trajectories for the vertical (y-axis):
Listed below are the key steps in the methodology to derive and analyze the condition-age matrix:
The scatter plot resulting from an age-reinvestment matrix can be analyzed in a variety of ways, including
Performance and Variances
Variances in the age-reinvestment matrix, could arise from:
Above the trend line:
Listed below are some of the merits and advantages of the condition-age matrix:
