ELECTREIIIDistillation {MCDA}

ELECTRE III ranking

Description

This function computes the two ELECTRE III distillations, or rankings.

Usage

ELECTREIIIDistillation(
  performanceTable,
  criteriaWeights,
  minMaxcriteria,
  preferenceThresholds,
  indifferenceThresholds,
  vetoThresholds
)

Arguments

performanceTable

Matrix or data frame containing the performance table. Each row corresponds to an alternative, and each column to a criterion. Rows (resp. columns) must be named according to the IDs of the alternatives (resp. criteria).

criteriaWeights

Vector containing the weights of the criteria. The elements are named according to the IDs of the criteria.

minMaxcriteria

Vector containing the preference direction on each of the criteria. "min" (resp. "max") indicates that the criterion has to be minimized (maximized). The elements are named according to the IDs of the criteria.

preferenceThresholds

Vector containing preference thresholds for each criterion.

indifferenceThresholds

Vector containing indifferences thresholds for each criterion.

vetoThresholds

Vector containing veto thresholds for each criterion.

Value

The function returns two lists, one for each distillation.
