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

methodParameters

Represents parameters.: “hierarchy node” is the ID of the hierarchy criterion for which the analysis should be performed; “transformToUtilities” means if data should be tranformed into values from range [0-1]; “boundariesProvided” means if inputsOutputs file contains information about min and max data for each factor.

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

<methodParameters>
        <parameter id="hierarchyNode">
    <value><label>%1</label></value>
</parameter>
        <parameter id="transformToUtilities">
                <value><boolean>%2</boolean></value>
        </parameter>
        <parameter id="boundariesProvided">
                <value><boolean>%3</boolean></value>
        </parameter>
</methodParameters>

where:

%1 is a parameter named “hierarchy node”. This is a string. The default value is root.
%2 is a parameter named “transform to utilities”. This is a boolean. The default value is true.
%3 is a parameter named “boundaries provided”. This is a boolean. The default value is false.
