Abstract

A method for determining a maintenance schedule of geographically dispersed physical assets includes receiving asset data including infrastructure relationships between the assets, modeling failure risk of the assets based on spatial, temporal and network relationships, and producing the maintenance schedule according to a combination of the risk model, asset data, maintenance, and external operation constraints. The maintenance schedule may be corrective and/or strategic.

Claims

1. A non-transient computer program product for determining a modeling failure risk of geographically dispersed physical assets, the computer program product comprising:

a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising;

computer readable program code configured to receive asset data including spatial, temporal and network relationships between the assets; and

computer readable program code configured to model failure risk of the assets based on the spatial, temporal and network relationships, wherein a model of failure risk identifies an asset likely to require maintenance.

2. The computer program product in claim 1, wherein the computer readable program code configured to model the failure risk of the assets, further performs the modeling of the failure based on environmental data.

3. The computer program product in claim 1, wherein the computer readable program code configured to model the failure risk of the assets, performs the modeling of the failure based on asset condition data.

4. The computer program product in claim 1, wherein the model of failure risk outputs a replacement cost estimate for each of the assets.

5. The computer program product in claim 1, wherein the model of failure risk outputs a maintenance cost estimate for each of the assets.

6. A non-transient computer program product for determining a maintenance schedule of geographically dispersed physical assets, the computer program product comprising:

a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising;

computer readable program code configured to receive a model of asset failure risk based on asset data including spatial, temporal and network relationships between the assets; and

computer readable program code configured to produce the maintenance schedule according to a combination of the risk model, asset data, maintenance, and external operation constraints.

7. The computer program product in claim 6, wherein the model of failure risk includes a replacement cost estimate for each of the assets.

8. The computer program product in claim 6, wherein the model of failure risk includes a maintenance cost estimate for each of the assets.

9. The computer program product in claim 6, wherein the maintenance schedule is based on a replacement cost estimate for each asset, a maintenance cost estimate for each asset and budget data.
