| Version: | 0.1.1 |
| Maintainer: | Lucas Sebastião de Paula <lucas@ime.eb.br> |
| Description: | Implementation of the MEthod based on the Removal Effects of Criteria - MEREC- a new objective weighting method for determining criteria weights for Multiple Criteria Decision Making problems, created by Mehdi Keshavarz-Ghorabaee (2021) <doi:10.3390/sym13040525>. Given a decision matrix, the function return the Merec´s weight vector and all intermediate matrix/vectors used to calculate it. |

Usage
merec_weights(data, alternatives, optimizations)
Arguments
data |
A numeric data matrix in the format of a DECISION MATRIX, columns are the criteria, rows are the alternatives |
alternatives |
A character vector with the identification of alternatives |
optimizations |
A character vector with definition of minimization or maximization for each criterion, expected 'min' or 'max' only |
Value
A numeric vector with MEREC Weights (wj) and all matrix/vectors used to calculate it
Examples
alternatives <- c("A1", "A2", "A3", "A4", "A5")
optimizations <- c("max", "max", "min", "min")
data <- matrix(c(
c(450, 10, 100, 220, 5), # criterion 1 values
c(8000, 9100, 8200, 9300, 8400), # criterion 2 values
c(54, 2, 31, 1, 23), # criterion 3 values
c(145, 160, 153, 162, 158) # criterion 4 values
), nrow=5, ncol=4)
result <- merec_weights(data, alternatives, optimizations)
