Effective, inexpensive, and realistic on-going training is required to keep all Naval personnel proficient in their field. Nowhere is this more true than in steam propulsion engineering plants. The complex systems of valves, piping, and components require continuous refresher for watchstanders to perform their jobs safely. BoilerModel is a qualitative expert system designed using model-based reasoning principles and implemented in Ada. It accurately models a 1200 psi D-type boiler and its associated peripherals. The use of fundamental intra-component relationship ("first principles") and constraint propagation result in compact mode because there is no need for the extensive rule base found in conventional expert systems. Implementation in Ada permits the use of concurrent tasking to simulate simultaneous valve propagation found in real-world boiler systems. Additionally, Ada's portability allows BoilerModel to be compiled and run on virtually any machine, thereby making it an affordable and attractive complement to shipboard engineering training.
