TOPSIS: Implementation of TOPSIS Method for Multi-Criteria Decision Making Problems.

Description

The TOPSIS function implements the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) Method.

Usage

TOPSIS(decision, weights, cb)

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.

Value

TOPSIS returns a data frame which contains the score of the R index and the ranking of the alternatives.

Examples

d <- matrix(rpois(12, 5), nrow = 4)
 w <- c(0.2, 0.2, 0.6)
 cb <- c('max','min','max')
