EXPERT SYSTEM FOR DIESEL ENGINE MAINTENANCE. VOLUME I. FINAL REPORT

This report describes the results of a project involving the development of an expert diagnostic system for marine diesel engines. The purpose of the project was to develop a practical expert system aboard a modern, automated diesel-powered vessel to assist maintenance personnel in diagnosing existing engine failures and predicting future faults. Research activities involved developing robust diagnostic and automated reasoning techniques based on recent advancements in the field of expert systems. Alternative diagnostic reasoning techniques, such as rule-based inferencing, neural networks, structural and behavioral models, and probabilistic techniques, were investigated before settling on a final design involving probabilistic neural networks. Prototype systems were placed into operation aboard four large containerships powered by two-stroke, slow-speed diesel engines. The system configuration included data acquisition interfaces to existing engine monitoring and combustion analysis systems, as well as operation on a shipboard local area network.
