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 whether said hierarchical multi-stage model needs to be updated due to a change in said failure patterns; and
if said analysis indicates that said hierarchical multi-stage model needs to be updated, dynamically updating said hierarchical multi-stage model to obtain an updated hierarchical multi-stage model.

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.

10. An apparatus comprising:
-
a memory; at least one processor, coupled to said memory, and; a non-transitory tangible, computer-readable, recordable storage medium having embodied thereon instructions which when loaded into said memory configure said at least one processor to implement; 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, said hierarchical multi-stage model in turn comprising; a failure frequency analysis engine; a failure association analysis engine; and a failure prediction analysis engine; a change detection component which analyzes at least one data stream to determine whether said hierarchical multi-stage model needs to be updated due to a change in said failure patterns; and a sequential model updating component which, if said analysis indicates that said hierarchical multi-stage model needs to be updated, dynamically updates said hierarchical multi-stage model to obtain an updated hierarchical multi-stage model. - View Dependent Claims (11, 12, 13, 14, 15, 16)
