Computes efficiency scores for the given DMUs (alternatives) using SMAA-D method and additive Data Envelopment Analysis Model. For given number of buckets and samples, returns a matrix with alternatives in each row and buckets representing efficiency intervals in each column. Single cell indicates how many samples gave efficiency scores of respective alternative in respective bucket.
(For outputs, see below)
A list of criteria with specified preference direction. List has to contains at least one criterion that will be minimized (input) and at least one criterion that will be maximized (output).
A list of alternatives (DMUs).

“boundariesProvided” indicates if criteria values boundaries are given in criteria input or they have to be computed based on alternatives performances. “samplesNo” represents the number of samples to generate. “intervalsNo”, represents the number of buckets which efficiency scores will be assigned to. “transformToUtilites” indicates if given alternatives values are utilities or if they have to be firstly transformed to utilities.
