Methods and systems for distributed diagnostic reasoning

A method for distributed diagnostic reasoning for a subsystem of a complex system comprising:

• monitoring an operation of a component of a complex system with a computing node that includes a processor and a memory;
• 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, wherein the one or more SEAMS are unable to communicate directly with each other;
• creating a configuration file to form a distributed diagnostic reasoner (DDR) in conjunction with the one or more SEAMS and a workflow service associated with the component, the DDR also comprising static data associated with a fault condition;
• 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.
