Abstract

This invention relates to the estimation of asset lifetimes. An embodiment of the invention includes a method for estimation of asset lifetimes, that has the steps of inputting historic asset data into a system, generating a wear index for an asset based on the historical asset data, computing an amount of wear of an asset based on the wear index, and generating a remaining life of the asset based on the amount of wear of the asset.

Claims

1. A method for lifetime estimation of assets comprising the steps of:

inputting asset data into a system;

generating a wear index for an asset based on said asset data;

computing an amount of wear of an asset based on said wear index; and

generating a remaining life of said asset based on said amount of wear.

2. The method of claim 1, wherein said asset data includes spare part data.

3. The method of claim 1, wherein said step of generating a wear index includes an additive model.

4. The method of claim 1, wherein said step of generating a wear index further includes computing a wear index for each as set in said asset data.

5. A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps for lifetime estimation of assets, the method steps comprising:

inputting asset data into a system;

generating a wear index for an asset based on said asset data;

computing an amount of wear of an asset based on said wear index; and

generating a remaining life of said asset based on said amount of wear.

6. The program storage device of claim 5, wherein said asset data includes spare part data.

7. The program storage device of claim 5, wherein said method step of generating a wear index includes an additive model.

8. The program storage device of claim 5, wherein said method step of generating a wear index further includes computing a wear index for each asset in said asset data.
