Addressing consistent and reliable decision-making are crucial activities when choosing seemingly related alternatives for a set of criteria. Models and methods for aiding decisions such as analytic hierarchy process (AHP) were developed to handle quantified assessments of quality attributes, usually intangible and numerically hard to cope. We introduce the Decisor software tool to assist the use of AHP to drive complex decision modeling. We present a study of related tools describing advantages and drawbacks. The tool is user friendly, with intuitive data entry fields. Users may input alternatives and criteria, assigning weights from different judgment scales. Decisor’s main characteristic is its simple interface where the tool computes priority vectors for all alternatives and its consistency rates. It is also possible to operate with negative weighting, inferring Benefits, Opportunities, Costs, and Risks. The tool implements Group Decisions, using the geometric mean to combine criteria comparisons from selected stakeholders.
