SOAP service’s name:
Version:	1.0
Provider:	PUT
	`ImpreciseDEA-CCR-SMAA_ranks-PUT` (see SOAP requests for details)

Description

Computes ranks for the given DMUs (alternatives) using SMAA-D method and CCR Data Envelopment Analysis Model with imprecise data. For given number of samples returns a matrix with alternatives in each row and rankings in each column. Single cell indicates how many samples of respective alternative gave respective position in ranking.
