I've discovered that the output of MaxThink's Perm decision tree builder can easily be converted into a format that's compatible with the data file used by the free PHP program, TreeMenu. I've also discovered how data from a SQL database can be used as the input files for the Perm decision tree builder. As a result, the construction of complex decision trees can be totally automated, and the resulting decision tree can be distributed via the World Wide Web using the free TreeMenu program. I will demonstrate how these techniques can be used to build search trees for electronic documents, and their use in marketing. I will also demonstrate how that with a slight modification, my techniques can be used to implement the Analytical Hierarchy Process (AHP), using decision trees, without the need for the traditional use of matrix math.
