Aggregating Judgments and Priorities

There are two ways to aggregate individuals’ judgments and priorities with the Analytic Hierarchy Process (AHP). 

One way is to combine judgments by taking the geometric mean and computing a ‘combined’ set of priorities from these judgments by computing the principle right hand eigenvector.  This is referred to as aggregating individual judgments, or AIJ.   Another way is to aggregate individual priorities, know as AIP.  Here, priorities are computed for each participant and the priorities rather than the judgments aggregated.

Our experiment will compare results when both aggregation methods are used.
