Comparison Chain Method for AHP

Based on the principle of the Analytic Hierarchy Process, under the condition giving the pairwise comparison judgment matrix of the decision maker, a new method to determinate the decision maker’s priority vector for the comparison objects called Comparison Chain Method is proposed with a numerical example illustrating its applicability. Finally, the possible strong, weakness and extension of the chain comparison method are discussed, the comparisons with the other methods are made leading to the rationality of CCM, and the possible future research directions for AHP are foreseen.
