1. A method comprising:
- building a hierarchical multi-stage model of asset failure risk for complex heterogeneously distributed physical assets, said hierarchical multi-stage model considering heterogeneity of failure patterns for said assets;
analyzing at least one data stream to determine a change in said failure patterns; and
dynamically updating said hierarchical multi-stage model to obtain an updated hierarchical multi-stage model based at least in part on said change in said failure patterns;
wherein said considering heterogeneity of failure patterns for said assets comprises;
performing multi-dimensional segmentation on data comprising failure history for said assets to obtain segmented data; and
implementing hierarchical modeling to integrate heterogeneous clusters of failure risks for said assets from said segmented data.

Abstract
A hierarchical multi-stage model of asset failure risk for complex heterogeneously distributed physical assets is built. The hierarchical multi-stage model considers heterogeneity of failure patterns for the assets. At least one data stream is analyzed to determine whether the hierarchical multi-stage model needs to be updated due to a change in the failure patterns. If the analysis indicates that the hierarchical multi-stage model needs to be updated, the hierarchical multi-stage model is dynamically updated to obtain an updated hierarchical multi-stage model.
