DEASMAACCRPreferenceRelations

Provider:PUT
Version:1.0

Description

Determines dominance relations for the given DMUs (alternatives) using SMAA-D method and CCR Data Envelopment Analysis Model. For given number of samples returns a matrix with alternatives in each row and column. Single cell indicates how many samples of alternative in a row dominates alternative in a column.
