AHP-TOPSIS-2N method

Description

AHP-TOPSIS-2N is a hybrid multi-criteria decision-making method build from the AHP (Analytic Hierarchy Process) and TOPSIS-2N (Technique for Order of Preference by Similarity to Ideal Solution - with two normalizations).

Usage

ahptopsis2n(decision, criteria, minmax)

Arguments

decision

a matrix where rows correspond to the alternatives and columns correspond to criteria.

criteria

a matrix with pairwise comparison of criteria as in Analytic Hierarchy Process method.

minmax

a vector with objectives, minimize or maximize, to each criteria.

Details

criteria must be in the same order on the arguments.

Value

a list with consistency ratio and two dataframes with priority sorting of the alternatives.
