The design and implementation of a knowledge elicitation tool for use in specifying real-time control system requirements with the Core method is presented. The tool uses pattern recognition based on a Holland classifier to propose a control-system object space for subsequent manipulation, and it is in this area that emphasis is placed. Classifier systems in general are discussed, and an implementation using the Smalltalk-800 object-oriented programming environment is presented. Practical results are included. >
