 note = {When we estimate the relative distance between cities or the relative area of figures by the Analytic Hierarchy Process (AHP), it is often observed that a group decision usually outperforms an individual one. This paper addresses this phenomena and shows that the accuracy of estimates is improved in approximate proportion to the square root of the number of individuals in the group.},
