An Assessment Of Expert System Building Tools For Mining Applications

Solution of most engineering problems requires, in addition to vast numerical calculations, substantial use of practical judgement and expertise. With advances in applied mathematics and computer technology, the numerical aspects of problem solution have reached a considerable level of maturity. However, it is only recently that approaches like the expert systems methodology have been developed to incorporate the judgemental aspects as well. For rapid development and prototying of expert systems, expert system building tools or "shells" have become widely available. For the expert system developer, identification of the key characteristics of the problem domain and selection of the right expert system tool are of crucial importance. In this paper, the important attributes required in an expert system shell for use in the development of a mine ventilation planning expert system are discussed. These attributes are general in that most engineering problems in mining would have these requirements. Also, the results of an exercise undertaken to evaluate commercially available shells for application to mining engineering problems are presented.
