Multi-Criteria Method for Decision (TOPSIS)

Description

Assists in the TOPSIS analysis process, designed to return a ranking table with the best option as the analysis proposes. TOPSIS is a technique developed by Hwang and Yoon (1981), assuming the best alternative is closest to the positive ideal solution and farthest from the negative one. (LIU, H. et al., 2019) doi:10.1016/j.agwat.2019.105787.

Usage

TopSisWM(TabTo = NULL, P.Pesos = NULL, solpo = NULL, sort.rank = TRUE)

Arguments

TabTo	A table or matrix containing row and column names, with only numeric values. Default is NULL.
P.Pesos	A vector of weights for each criterion. Must have a weight for each column of the table. The sum of weights must be 1. Default is NULL.
solpo	A vector indicating if each criterion is to be maximized ("+") or minimized ("-"). Must match the number of columns. Default is NULL.
sort.rank	Logical. If TRUE, the result is ordered by rank. If FALSE, keeps original input order. Default is TRUE.

Value

A matrix with the results of the TOPSIS analysis, including the distance to the positive ideal solution (d+), the distance to the negative ideal solution (d-), the relative closeness (eu), and the final rank.

Examples

data(Topex1)
Tabela <- Topex1
Pesos <- c(0.5,0.3,0.2)
solucao <- c("-","-","+")
TopSisWM(Tabela, Pesos, solucao)

# Important: use row.names = 1 when importing local data
# Tabela <- read.csv("file.csv", sep=";", h=TRUE, row.names=1)
# Tabela <- read.table("Tabela.txt", h=TRUE, row.names=1)
