I have been thinking a bit lately about how best to determine a realistic useful life for long-lived assets and I believe that I have come up with a clever methodology for
a) assigning realistic, locally applicable useful lives to assets of a given type
b) estimating a realistic remaining useful life for assets if its condition score is known.
It requires that condition surveys of a reasonable sized sample of assets has been conducted on two occasions.
I have explained the methodology using dummy data here
But I would like to try it out on some real data.
If anybody would be willing to provide me with some real data, I would only be to pleased to run the analysis on it too see what I come up with.
