A method for diagnostic reasoning of faults appearing in a vehicle health monitoring system (VHM) is provided. One of alternatively a signal mode or a failure mode state is identified based on an input. If a signal is identified, the signal is queried to determine if the signal indicts a failure mode. If the signal indicts the failure mode, an intermittent watch flag is set for the failure mode. A count representing a number of occurrences of the signal as an intermittent fault is incremented. It is determined if the count exceeds a predetermined threshold. If the count exceeds the predetermined threshold, the intermittent fault is determined to be a permanent fault.

Provided are methods and systems distributing a data message to an unknown destination device across at least one spatial boundary and at least one administrative domain boundary from an originating device. The system includes at least one distributor module that exists within each administrative domain of a network through which the data message may originate, may terminate or may traverses in route from the originating device to the unknown destination device. Each administrative domain within each of a plurality of equipment platforms has at least one distributor module. The system also includes a domain bridge spanning the at least one administrative domain boundary within an equipment platform of the plurality through which the data message traverses in route to the unknown destination device. The system operates using a network discovery service whereby an advertisement is published for a specific type of data by the unknown destination device. The advertisement is promulgated throughout the network. Each distributor module in the network acts a surrogate for the unknown destination device by accepting the data and relaying it to another surrogate until it arrives at the destination device. The system allows the data to pass through both spatial and administrative barriers automatically.

A system for monitoring the health of a component includes a memory configured to store a health management system for evaluating the health of the component. The health management system includes a first prognostic module, a first diagnostic module, a first failure mode module, and a first functional module. A processor is coupled to the memory and configured to retrieve the health management system from the memory; receive a first prognostic indicator associated with the health of the component; determine a first predicted diagnostic indicator based on the prognostic indicator with the prognostic module; determine a first failure mode probability based on the first predicted diagnostic indicator with the diagnostic module; determine a first failure mode vector based on the first failure mode probability with the failure mode module; and generate a first functional output based on the first failure mode vector with the first functional mode module.

Methods, systems and apparatus are provided for ranking tests of interest. A set of failure modes of interest and a set of tests of interest are determined A differentiation factor is then computed for each of the tests of interest, and each of the tests of interest can then be ranked based on their respective differentiation factors.
