ISHIZAKA, Alessio. Clusters and pivots for evaluating a large numberof alternatives in AHP. Pesqui. Oper. [online]. 2012, vol.32, n.1, pp. 87-102. Epub 08-Mar-2012. ISSN 0101-7438. http://dx.doi.org/10.1590/S0101-74382012005000002.
AHP has been successful in many cases but it has a major limitation: a larger number of alternatives requires a high number of judgements in the comparison matrices. In order to reduce this problem,we present a method with clusters and pivots. This method also helps with a further four problems of the Analytic Hierarchy Process. It enlarges the comparison scale, facilitates the construction of a consistent or near consistent matrix, eliminates the problem of the choice of the priorities derivation method and allows the use of incomparable alternatives.
