VIKOR: Implementation of VIKOR Method for Multi-Criteria Decision...

In MCDM: Multi-Criteria Decision Making Methods for Crisp Data

Description

The VIKOR function implements the "VIseKriterijumska Optimizacija I Kompromisno Resenje" (VIKOR) Method.

Usage

VIKOR(decision, weights, cb, v)

Arguments

decision	The decision matrix (m x n) with the values of the m alternatives, for the n criteria.
weights	A vector of length n, containing the weights for the criteria. The sum of the weights has to be 1.
cb	A vector of length n. Each component is either cb(i)='max' if the i-th criterion is benefit or cb(i)='min' if the i-th criterion is a cost.
v	A value in [0,1]. It is used in the calculation of the Q index.

Value

VIKOR returns a data frame which contains the score of the S, R and Q indixes and the ranking of the alternatives according to Q index.
