Third International Diagnostic Competition

We present the third implementation of a framework created jointly by NASA Ames Research Center, Palo Alto Research Center, and Delft University of Technology to compare and evaluate diagnosis algorithms (DAs). This year's competition, DXC'11, introduces a software track in addition to the industrial and synthetic tracks of previous competitions. A total of eleven DAs competed in the three tracks. The paper describes the systems, diagnostic problems of the tracks, fault scenarios, evaluation metrics, participating DAs, results and analysis.
