Spatial-Temporal Optimization of Physical Asset Maintenance

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.

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.
