On July 7-9, 2009, Dr. John W. Sheppard and the MSU Department of  Computer Science hosted a meeting of the Diagnostic and Maintenance Control (DMC) subcommittee of the IEEE Standards Coordinating Committee 20 (SCC20) on Test and Diagnosis for Electronic Systems. The DMC holds four meetings per year at various locations around the US and Europe and is responsible for developing IEEE standards for fault diagnostic systems. At this meeting, ten people from organizations such as Boeing, Lockheed Martin, Honeywell, the US Navy, and the US Army gathered to resolve comments on the recent ballot of the IEEE P1232 AI-ESTATE standard. This standard specifies data formats for diagnostic knowledge bases and software APIs for diagnostic reasoners. Currently, the US DoD is in the process of demonstrating P1232 in preparation of issuing a mandate that this standard be used in all future procurements of diagnostic technology for automatic test equipment. Dr. Sheppard is the Vice Chair of SCC20, the Secretary of the DMC, and the IEEE Computer Society's liaison between the Standards Activities Board and SCC20. [July 2009]
