Two direct manipulation tools, presented metaphorically as a {\textquotedblleft}pump{\textquotedblright} and a {\textquotedblleft}hook,{\textquotedblright} were developed and applied to the treemap to support AHP sensitivity analysis. Users can change the importance of criteria dynamically on the two-dimensional treemap and immediately see the impact on the outcome of the decision. This fluid process dramatically speeds up exploration and provides a better understanding of the relative impact of the component criteria. A usability study with six subjects using a prototype AHP application showed that treemap representation was acceptable from a visualization and data operation standpoint.}, keywords = {AHP, analytic hierarchy process, decision support, treemap, User interfaces, Visualization}, isbn = {1047-7047, 1526-5536}, doi = {10.1287/isre.6.4.357}, url = {http://isr.journal.informs.org/content/6/4/357}, author = {Asahi,Toshiyuki and Turo,David and Shneiderman, Ben} }
