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.
