Abstraction for extracting data from a CSV file to run the wispcalc function

Description

File requirements: - Separated by comma or semicolon - Do not use thousands separator Example file in https://github.com/dioubernardo/rwisp/blob/main/inst/extdata/example.csv

Usage

rwispfromcsv(file)

Arguments

file

the name of the file

Value

list with 3 matrix, ui = ranking and the global ui, normalizedData = normalized data, utilities = utility values

Examples

result <- rwispfromcsv(system.file("extdata", "example.csv", package = "rwisp"))

Integrated Simple Weighted Sum Product Method - WISP

Description

Implementation of An Integrated Simple Weighted Sum Product Method - WISP More information about the method at https://doi.org/10.1109/TEM.2021.3075783 More information about the implementation at https://github.com/dioubernardo/rwisp/blob/main/README.md

Usage

wispcalc(data, alternatives, optimizations, weights)

Arguments

data

A numeric data 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

weights

A numeric vector with the criteria weights, the sum of all must be 1

Value

list with 3 matrix, ui = ranking and the global ui, normalizedData = normalized data, utilities = utility values

Examples

alternatives <- c("A1", "A2", "A3", "A4", "A5")
optimizations <- c("max", "min", "max", "max", "min", "max", "min", "max", "min", "max")
weights <- c(0.07, 0.07, 0.07, 0.14, 0.2, 0.08, 0.12, 0.125, 0.05, 0.075)
data <- matrix(c(
  c(3, 4, 6, 5, 2), # criterion 1 values
  c(7, 6, 4, 6, 8), # criterion 2 values
  c(4, 5, 5, 6, 3), # criterion 3 values
  c(4, 5, 6, 5, 4), # criterion 4 values
  c(6, 5, 4, 3, 6), # criterion 5 values
  c(4, 5, 5, 6, 3), # criterion 6 values
  c(6, 5, 5, 4, 6), # criterion 7 values
  c(8, 8, 9, 7, 7), # criterion 8 values
  c(5, 6, 7, 8, 7), # criterion 9 values
  c(8, 9, 9, 9, 8) # criterion 10 values
), nrow=5, ncol=10)
result <- wispcalc(data, alternatives, optimizations, weights)
