This paper gives a brief introduction to the system Java Geometry Expert (JGEX). This system consists of three parts: the drawing part, the proving and reasoning part, and the most distinctive part – the part for generating visually dynamic presentation of proofs in plane geometry. The current version of JGEX is beta 0.80, which is available at our website woody: http://woody.cs.wichita.edu.

This paper provides a methodology, or process, that can be used to construct expert systems. The methodology is suited primarily for building troubleshooting, advisory, and diagnostic expert systems; however, it also can be useful for building other types of systems.

Management at Mary Kay Cosmetics supported development of an expert system (ES) to assist with the problems inherent with package design. Although the ES performed well and was clearly beneficial, use of the ES discontinued after a short time and the package design process returned to pre-ES practices. Within the context of this case this paper describes from a managerial perspective how and wh...
