An Evaluation of Five PC-Based Expert System Shells

Abstract

Five expert system shells (three example-based and two rule-based) were evaluated for this project. These shells offer an advantage in that they can help reveal interrelationships that are not readily apparent, since they draw their own conclusions from the data. However example-based systems are more rigid and inflexible which makes them more difficult to work with. Rule-based systems are more difficult to learn to use, since they involve entering if-then- else rules. However (especially in the case of INSIGHT 2+) they offer more flexibility and freedom, since the knowledge engineer or programmer has control over the development and use of the rules. Of the five shells evaluated, INSIGHT 2+ offers the best features for the development of the propellant formulation expert systems. Keywords: Expert system shells, Artificial intelligence, Propellant formulations, Personal computers.
