Guide for the Management of Expert Systems Development

Abstract : This appendix provides assistance in selecting the most appropriate tool for a particular expert system development project. A strong foundation in the usage of any specialized tool (e.g., chemical assay equipment or an expert system shell) is prerequisite to tool selection. Familiarity and reasonable facility with expert systems technology and knowledge engineering are necessary prior to applying the techniques presented in this appendix. This appendix outlines a selection method that was adapted from one developed at The RAND corporation for expert system tool evaluation. It is applicable after the decision has been made that such a tool is needed and the characteristics of that need are known. In particular, this involves (1) understanding the problem that shows potential for applied expert system technology and (2) choosing the best solution alternative. The term expert system means a system built using a knowledge-based approach to software development that applies expert knowledge to solve difficult real-world problems.
