When we were designing our decision support tools we had many requests to use artificial intelligence, fuzzy logic, and other buzz words. At the end of the day our statistical analysis research concluded that it was MUCH better to stay simple for a number of reasons 1) General results were better under impact of real market action. 2) Maintenence of the tools so that you can use them day in and day out. If you have something very complex it will take a long time to fix and adjust. We found the best resluts were to alert to simple, but valid statistical patterns in real-time. Our research was based on Deming's analysis of the bell curve.
