Inputs

(For outputs, see below)

inputsOutputs

Description:

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.
