The software supporting the sustainable energy transition

HELDA is a further development of MCDA Tool KIT which was originally created for nuclear emergency management at KIT-ITES. HELDA is the result of the ongoing collaboration of KIT-ITES and KIT-ITAS to provide an MCDA software to meet the demands for sustainabilty assessment. HELDA comes with a refreshed user interface, new logo, additional features and a plug-in for interactive stakeholders involvement. The features that differentiate HELDA from its original source are marked with an *.

MCDA methods available

HELDA includes the following aggregation methods:

• Weighted sum 
• Weighted product
• Weighted rank 
• TOPSIS
• VIKOR
• User defined expression 
• PROMETHEE I and II*
• ELECTRE III*

And the following weighting methods:

• SWING
• SMART
• Relative weights (sliding bar) 
• SRF method*
• Absolute weights (direct input)*

Dealing with uncertainty

HELDA can perform uncertainty analysis on input data (performances and weights) using:

• Probability distributions
• Monte Carlo simulation

You can also conduct sensitivity analysis on input data.

Graphical representation

HELDA allows visualization of the following: 

• Weighting sets analysis for single or multiple stakeholder*
• Ranking of alternatives from best to worst (including uncertainty analysis)
• Sensitivity analysis on input data (stability graph)
  • Values
  • Weights
  • Thresholds*
  • Alternatives*
• Dominance graph*

Stakeholders integration*

Plugin for online surveys* - Provided upon request for academic and teaching purposes. Please contact us via helda ∂does-not-exist.lists kit edu for further information.
