PROMETHEE I, II, and III Methods

Description

The PROMETHEE method is a multti-criteria decision-making method addressing with outranking problems. The method establishes a preference structure between the alternatives, having a preference function for each criterion. IN this context, three variants of the method is carried out: PROMETHEE I (Partial pre-ordering), PROMETHEE II (Total pre-ordering), and PROMETHEE III (pre-ordering by inervals).

Usage

promethee123(alternatives, criteria, decision_matrix, min_max,
normalization_function, q_indifference, p_preference, s_curve_change, criteria_weights)

Arguments

alternatives	The names respective to set of alternatives in evaluation
criteria	The names respective to set of criteria in evaluation
decision_matrix	A matrix where rows correspond to the criteria and columns correspond to alternatives, there is inputed the performance of alternatives in each criterion
min_max	A vector with objectives, minimize or maximize, to each criteria.
normalization_function	Numerical description relative to each type of normalization function to each criterion
q_indifference	Indifference threshold
p_preference	Preference threshold
s_curve_change	Threshold of changing in the curve
criteria_weights	Numerical representation of the respective importance for each criterion

Details

- For normalization function we have six types: [ 1 ] for USUAL (0 or 1) — [ 2 ] for U-SHAPE (0 or 1) q [ 3 ] for V-SHAPE (x/p or 1) p [ 4 ] for LEVEL (0, 0.5 or 1) q , p [ 5 ] for V-SHAPE I (0, (x-q)/(p-q) or 1) q , p [ 6 ] for GAUSSIAN (0 or 1-e^(-x^2/2*s^2)) s ———————————- q = indifference parameter p = preference parameter s = parameter to indicate change in the preference curve

- The input of thresholds depends of the type of preference function used;

- The sum of weights must be 1;

Value

- Performance in each criterion;

- Global Index of Importance;

- Importance Flows (Positive, Negative, and Net);

- Preference relations in PROMETHEE I;

- Total Outranking in PROMETHEE II;

- Preference relations in PROMETHEE III;

- Graphical representations of PROMETHEE I, II, and III.
