PROMETHEEII: The PROMETHEE Outranking Method

In PrometheeTools: PROMETHEE and GLNF for Ranking and Sorting Problems

The PROMETHEE Outranking Method

Description

PROMETHEE is a multicriteria method that quantifies preference relationships and obtains the positive, negative and net flows of the alternatives, generating rankings that reflect the decision-maker's preferences. This function applies PROMETHEE I (partial ranking) and PROMETHEE II (full ranking). This function can handle a large number of alternatives.

Usage

PROMETHEEII(matrix_evaluation, data_criteria)

Arguments

matrix_evaluation	The matrix includes the values for all alternatives. The alternatives profiles are rows and columns correspond to the evaluation criteria.
data_criteria	Matrix with the parameter information (rows) for each criterion (columns). The rows of parameters are in the following order: Function Type, Indifference Threshold, Preference Threshold, Objective and Weight.

Details

• The types of preference function are as follows: "linear", "v-shape", "usual", "u-shape", "level" and "gaussian".

• The preference and indifference thresholds depend on the type of function selected. The preference threshold requires definition (is non-zero) for all functions except for "usual" and "u-shaped". The indifference threshold is non-zero for "linear", "level" and "u-shaped" functions.

• In the objective write "max" to maximize or "min" to minimize.

• The sum of the weights of all criteria must be equal to 1.

• This implementation of PROMETHEEII is designed to handle a large number of alternatives (it has been tested with 10,000 alternatives) much higher than the previous implementations in R (promethee123 and PROMETHEE).

Value

-NF Matrix with positive and negative flows (PROMETHEE I) and net flows for complete ranking (PROMETHEE II).

-NFC Net flows matrix by criterion.
