AHP-express: A simplified version of the analytical hierarchy process method

This work presents in detail a simplified method for the application of the analytic hierarchy method (AHP) that aims to calculate the priorities of each alternative against a set of criteria with only n-1 comparisons of n alternatives for each criterion (instead of (n(2)-n)/2 comparisons in the original method proposed by Saaty), followed by the application of a simple formula. This increases the attractiveness of the AHP method for business applications where decisionmakers are subject to a time constraint. Simplified AHP method. Reduced number of comparisons.
