dc.description.abstract | Treemaps, a visualization method for large hierarchical data spaces, are used
to augment the capabilities of the Analytic Hierarchy Process (AHP) for
decision-making. Two direct manipulation tools, presented metaphorically
as a pump and a hook, 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 6 subjects using a
prototype AHP application showed that treemap representation was
acceptable from a visualization and data operation standpoint.
