in Additional Information Compensatory decision methodologies, such as AHP are the most effective way to prioritize alternatives. A rational decision is one that best achieves an individual's or group's objectives -- their wants. However, there are sometimes constraints, p...

in Additional Information When an individual or small group derives priorities in an AHP model, they can evaluate either from the top down (from goal to objectives to alternatives) or bottom up (from alternatives, to covering objectives, to top level objectives). A to...

in Additional Information Prioritization and decision making is often performed in a group context. There are two ways to aggregate individuals' judgments and preferences with AHP, depending on whether the group is assumed to act together as a synergistic group in achievin...
