The purpose of this paper is to present an application of the AHP technique to a mining method selection problem faced by a Colombian mining company; in this case we use five decision makers. Next, a final aggregation of criteria priorities by AHP and ENTROPY is proposed for include subjective and objective weighting. Next, VIKOR method is performed to present a compromise solution; VIKOR is used to solve the problem without decision makers dependence; the weights for VIKOR are aggregated using an a priori λj subjective weighting obtained from AHP method. Whereas entropy weighting provides a dynamic and objective assessment of all criteria, AHP weighting determine all decision makers preferences. Finally, an analysis of the results is carried out to derive conclusions in relation to the effects of the modeling processes of both techniques.
