Inputs

(For outputs, see below)

inputsOutputs

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). In addition, minimum and maximum possible value for each critetion can be defined. If not defined, they will be computed from alternatives performances on given criteria. For each criterion, one can specify characteristic points of additive value function.

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

<criteria>
                     <criterion>
                                                     <scale>

                                                                     <preferenceDirection>
                                                                             [...]

                 </alternatives>

%1 is a parameter named “boundariesProvided”. This is a boolean. The default value is false.
