method parameters

Description:

Represents method parameters.
“tolerance” represents the fraction for creating interval data (created interval: [data*(1-tolerance), data*(1+tolerance)]), “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, “functionShapeProvided” means if inputsOutputs file contains information about the shapes of value function for given factor.

GUI information:

  • Parameter values can be defined via the GUI or the XMCDA file, by default via GUI.
  • Name: tolerance
    • Constraint description: The value should be non-negative.
    • Type: float
    • Default value: 0.00
  • Name: transform to utilities
    • Default value: true
  • Name: boundaries provided
    • Default value: false
  • Name: function shapes provided
    • Default value: false
