Intelligent Diagnostic Reasoning System deployment process and results

Lockheed Martin Simulation, Training & Support (LM STS) has developed an Intelligent Diagnostic Reasoning System (IDRS) that can reduce the time and cost to diagnose a failure by isolating to the fault more quickly and reducing callout ambiguity. IDRS uses engineering knowledge and historical test and maintenance data to develop diagnostic models enabling intelligent decision support. IDRS models and services are based on the IEEE 1232^trade Artificial Intelligence Exchange and Service Tie to All Test Environment (AI-ESTATE) standard. IDRS is deployed at Ogden Air Logistics Center (OO-ALC) through a partnership between LM STS and OO-ALC 309^th Maintenance Wing (309 MXW) Software Maintenance Group and Electronics Maintenance Group at Hill Air Force Base. This paper will outline the selection of the Line Replaceable Unit (LRU), the deployment of IDRS, the results obtained, and the benefits of IDRS.
