As explained in the introduction, to conduct the MCA the combined application of AHP and PROMETHEE/GAIA was proposed. AHP was implemented in MS Excel® and Matlab® and was employed as a first step to establish the criteria weights that were later required as inputs to the PROMETHEE model. Meanwhile, for the application of PROMETHEE/GAIA the software Decision Lab 2000 (Visual Decision Inc., 2009) was used.
