Description

Determines dominance relations 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 column. Single cell indicates how many samples of alternative in a row dominates alternative in a column.

methodParameters

“samplesNb” represents the number of samples to generate.

The input value should be a valid XMCDA document whose main tag is <methodParameters>. It must have the following form:

    </parameter>
</methodParameters>

where:

  • %1 is a parameter named “number of samples”. This is a int, and the value should conform to the following constraint: The value should be a positive integer.. More formally, the constraint is:

    %1 > 0
    

    The default value is 100.

  • %2 is a parameter named “tolerance”. This is a float, and the value should conform to the following constraint: The value should be a non-negative number.. More formally, the constraint is:

    %2 >= 0
    

    The default value is 0.0.
