The present application relates to a method for determining multiple simultaneous fault conditions on complex systems. The method comprises receiving symptoms of a complex system from monitors. When some of the symptoms suggest the existence of multiple simultaneous fault conditions, then the method creates a symptom signature, creates one or more failure mode signatures, and creates an error code for each failure mode signature in regard to the symptom signature. Each failure mode signature is associated with only one failure mode. A Hamming distance is determined for each failure mode indicated as possibly causing the original fault condition. Each failure mode with the minimum Hamming distance and same Hamming Code are grouped together as being one of the multiple simultaneous fault conditions. All remaining failure modes with other Hamming distances are then assigned into one of the simultaneous fault conditions.

Methods for determining multiple simultaneous fault conditions

A method for accumulating fault condition data from a hierarchical system is presented comprising monitoring an operation of a component with a computing node that includes a processor and a memory. The memory contains a configuration file comprising failure modes (FM), symptoms, tests that identify the symptoms and a corrective action for the symptom. The method further comprises populating at least one of the processor and the memory of the computing node with one or more standardized executable application modules (SEAM) and a workflow service. The one or more SEAMS is configured to create a fault condition record by collecting all FMs that manifest the symptom. For all FMs collected, a list of unique symptoms is produced. Further all tests that can identify the listed unique symptoms and all of the corrective actions associated with the FMs that manifest the symptom are determined from the memory device.

Method for performing condition based data acquisition in a hierarchically distributed condition based maintenance system

Systems and methods are provided for customizing workflow in a condition based health maintenance ('CBM') system computing node. The computerized method comprises identifying a first standardized executable application module ('SEAM'), wherein the first SEAM is configured to generate a first event associated with particular data being processed by the first SEAM and identifying a second SEAM, wherein the second SEAM is configured to generate a subsequent event associated with the particular data processed by the first SEAM. The computerized method further comprises creating a quasi-state machine associating a unique responses to the first event and associating a unique responses to the subsequent event, and installing the quasi-state machine into the SDS of the computing node from which the workflow service state machine retrieves the one or more unique responses from the quasi-state machine to the first event for processing by the second SEAM to produce the subsequent second event.

Methods and reconfigurable systems are provided for monitoring the health of a complex system. The reconfigurable system comprises a plurality of standardized executable application modules containing instructions to perform one of a plurality of different standardized functions. The system further comprises a plurality of computing nodes arranged in a hierarchical structure comprising one or more layers of computing nodes. Each computing node of the plurality runs a host application and a workflow service module, each computing node thereby being configured by a configuration file that directs the execution of any of the standardized executable application modules in a cooperative fashion by the host application via the workflow service module. The system also comprises a loading means for populating each computing node with one or more standardized executable application modules of the plurality, a communication means, and a configuration means for programming the populated standardized executable application modules.

A method for distributed diagnostic reasoning is provided. The method includes establishing a computing node monitoring the operation of a component of a complex system and populating at least one of a processor and the memory of the computing node with one or more standardized executable application modules (SEAMs) and a workflow service. The method further includes creating a configuration file in combination with several SEAMS to create a distributed diagnostic reasoner (DDR) associated with the component. The method also comprises installing the configuration file in the computing node for execution by the processor; and initializing the one or more SEAMS, the configuration file and the workflow service, wherein the workflow service facilitates data flow between the one or more SEAMS and the static data associated with a fault condition resident in the configuration file.

Systems and Methods are provided for coordinating computing functions to accomplish a task. The system includes a plurality of standardized executable application modules (SEAMs), each of which is configured to execute on a processor to provide a unique function and to generate an event associated with its unique function. The system includes a configuration file that comprises a dynamic data store (DDS) and a static data store (SDS). The DDS includes an event queue and one or more response queues. The SDS includes a persistent software object that is configured to map a specific event from the event queue to a predefined response record and to indicate a response queue into which the predefined response record is to be placed. The system further includes a workflow service module, the work flow service module being configured to direct communication between the SDS, the DDS and each of the plurality of SEAMs.

The present invention relates to a distributed fuel system, wherein a plurality of fuel tanks used for storing fuel are distributed in different locations. The fuel tanks are connected to each other via a manifold which permits fuel to flow therein. The distributed fuel system includes a plurality of control components interposed at predetermined points of the manifold to permit or restrict the flow of the fuel contained in the manifold in response to control signals. A method for distributing the fuel between the fuel tanks to achieve predetermined levels in each of the fuel tanks comprises the steps of determining the status and condition of the fuel system. The functions to be performed are then selected. Based on the system status and the functions to be performed, the configuration of the control elements is selected to perform the functions to be performed. The control signals are outputted to the control components to obtain the desired configuration of the control components for causing the fuel flow within the distributed fuel system to accomplish the desired functions, thereby yielding the desired fuel distribution.
