The Analytic Hierarchy Process (AHP), a decision making method based upon division of problem spaces into hierarchies, is visualized through the use of treemaps, which pack large amounst of hierarchical information into small screen spaces. Two diect manipulation tools presented metaphorically as a "pump" and a "hook", were developed and applied to the treemap to support AHP sensitivity analysis. The problem of constuction site selection is considered in this video. Apart from its traditional use for problem/information space visualization the reemap also serves as a potent visual tool for "what if" type analysis. |
