AHP (Analytic Hierarchy Process) is a multi-criteria, mathematical technique that allows you to analyze complex decisions. This process employs a 1 to 9 weighting scheme with pair-wise comparisons. If you are unfamiliar with the AHP process, there many books and resources on the Internet that describe the AHP process.
AHP Decision allows you manage a set hierarchical matrices with automatic computation of all matrix and sub-matrix values whenever any element is changed. Changing cell values is done through contextual menus, so all you have to do click on the cell you want and choose a new value. Navigation through the matrices hierarchy is simple as point and click. AHP Decision makes managing the AHP process simple.
