Abstract

Mechanism modeling is currently a very active area of Artificial Intelligence. Several theories of mechanism modeling have resulted from this work and have been applied to such tasks as simulation, analysis, and troubleshooting in domains such as electronic circuit analysis and steam plant operation. This thesis addresses some of the issues involved in modeling the domain of turbojet aircraft engine operation. A causal model of the turbojet engine, based on the kinds of relationships which exist between engine parameters, is described. The utility and limitations of currently accepted theories of mechanism modeling for modeling the operation of the turbojet engine are also discussed, along with suggestions for overcoming some of the limitations. Finally, the applications for qualitative models of the turbojet engine are explored. The current causal model has been implemented in INTERLISP-VAX on a Vax 11/780 for the purposes of simulation and analysis, along with a facility for explaining the results of such a simulation.
