Usage

ELECTRE3(scores, q, p, v, w)

Arguments

scores

Matrix or data frame containing the performance table. Each column corresponds to a criterion, and each row to an alternative.

q

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

p

Vector containing the preference threshold on each of the criteria. The elements are named according to the IDs of the criteria.

v

Vector containing the veto thresholds for each criterion. The elements are named according to the IDs of the criteria.

w
