We do NOT make decisions intuitively. We make a decision based on the objective, the criteria and sub-criteria, influences, and alternative actions. This useful information is organized in order to rank the decision options [1]. However, it is very difficult to quantify the importance of the criteria and sub-criteria, and accordingly, it is a difficult task to quantify the priorities of the decision options.

Analytic Hierarchy Process(AHP) [2], which is based on the assumption that our decision process is shaped like a hierarchical structure, is one of the solutions to this quantification problem. AHP is able to obtain the weight values of the criteria through pairwise comparisons. Although AHP was first proposed in the 1970s, this has been extensively studied and applied to actual group decision-making.

This application is a flexible interface to construct, visualize, and share users’ own decision-making structure expressed as AHP.
