1. An asset fleet health monitoring system, comprising:

  • a sensor data feed module for providing multivariate sensor data from a plurality of fleet assets;

    a database for storing empirical models of assets in the fleet;

    an estimation engine disposed to generate estimated sensor values and residuals in response to receiving from the data feed an observation of multivariate sensor data for an asset in the fleet, using a corresponding empirical model for the asset stored in said database;

    an incident diagnostics engine module responsive at least to said residuals to determine whether an incident should be registered for said asset; and

    a graphical interface module having a hierarchical fleet view of the health status of all assets and an exception-based view of all assets having registered incidents.
