GRASPERS - A GRAPHICS DECISION SUPPORT SYSTEM: ITS DEVELOPMENT AND APPLICATIONS
Abstract
Managers have used graphics for years to support them in their presentations and analysis of information. Conventionally, graphs and charts were prepared by graphic designers and draftsmen. Recently, with the advent of graphics software and appropriate hardware managers can produce their own graphs and charts. Existing computer graphics systems do speed up the graphics drawing process. However, they do not address the most important issue which is graphics selection. Human expertise in graphics design is required to help users select appropriate graphs to accomplish the stated purpose of a graphic presentation. That is, effectiveness is more important than efficiency. Furthermore, existing computer graphics systems are designed as tools for facilitating graphics drawing, not for supporting decision making by graphing. They are intended to be graphics drawing support systems, not graphics decision support systems. An ideal computer graphics system should be both effective and efficient, and easily used by novices. That is, a computer graphics system should contain human expertise in both graphics selecting and drawing processes, and emphasize user friendliness. A graphics decision support system called GRASPERS was designed to achieve the objectives of ease-of-use, efficiency, and effectiveness. The conventional decision support system techniques were used for designing graphics drawing processes. Expert system techniques were used for designing the graphics selecting process. To evaluate the performance of GRASPERS in a real-world situation, a case study was carried out at the Firstier Bank of Lincoln, Nebraska. The results of case study support the contention that GRASPERS has performed as expected.
