Basic Research on an Expert System for Navigation at Sea : Engine Operation Expert System at the Control Tower

This paper is concerned with an expert system for engine operation at the control tower, as one sub expert system of an expert system for navigation at sea. The purposes of this study are as follows. (1) To classify the engine operation functions. (2) To establish a knowledge representation and inference engine for accumulation and utilization of ship operation knowledge. The knowledge acquired from the engineer and some literatures have been represented by modified production rule. The summary of the results is shown below. (1) The readable knowledge representation has been suggested. (2) An inference engine for forward reasoning that suited to knowledge representation have been constructed. (3) Output of this expert system approximates to actual decision of the engineer.
