Download or read book Demonstration of Artificial Intelligence Technology for Transit Railcar Diagnostics written by Ian Mulholland and published by Transportation Research Board. This book was released on 1999 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report documents the results of a demonstration of an AI-based program that acts as a "diagnostic assistant" for transit railcar propulsion systems. The diagnostic program uses a hybrid AI approach with both model-based reasoning and expert system rules. The AI tool was tested at the Washington Metropolitan Area Transit Authority (WMATA) on direct current chopper propulsion systems of the 3000 series railcars. The system was determined to be easy to use and effective in diagnosing propulsion system faults.
