The PROMETHEE-GAIA FAQ

Currently (beta version), the software limits are the following:

• 10 000 actions,
• 10 000 criteria,
• 100 groups, categories and clusters,
• 100 000 evaluations,
• 10 scenarios.

These limits are not inherent to the methodology and can be lifted if necessary.

However:

• Larger numbers of criteria are more difficult to analyze and can lead to redundant information. The PROMETHEE Software partly adresses this problem and makes sensitivity analyses easier by allowing to define groups of criteria and clusters.
• The quality (Delta) of the GAIA plane can be very low when the size of the problem is larger. Again this can be partly adressed by grouping criteria.

• Hello Bertrand, Evaluate monthly my actual suppliers is a similar task to select the best supplier. The only difference is that this is done constantly and we need a historical data to see how the suppliers are evolving. I saw that in visual promethee 1.3 you included a dashboard function that is still being developed. This dashboard will be related to what I'm talking? I can do this exporting the evaluation table to an excel sheet and creating a graph to evaluate the monthly evolution of suppliers, but are you planning to do something like this in this dashboard function? Thanks a lot,
• Hello Bertrand, I am going to use PROMETHEE-GAIA program for my P.hd program, could you tell me how can i get the right software?do i need to by or is it possible to get free? Thanks
• What is the difference between the two Editions of Visual PROMETHEE?
• Is it possible to display units within the Visual PROMETHEE evaluation table?
• I understand the difference between two different types of thresholds value. However, and knowing that the software does the work, I aim to know how does the preference function work with percentage threshold values. Imaging we choose linear preference function for one criterion. When you compare your d value with p o q, what value need you to compare with? In the example of choosing the site place in the demo, for the criterion "Price" this happens. I would be grateful if you could explain how does the function works with this kind of value. Thanks.
• Hi why can't we use a decimal number in weight cell?suppose that we fill some questioneer by likert spectrum and the weight is a decimal number, how can we input it?
• How can I use the Preference Function Assistant?
• What is the PROMETHEE Rainbow?
• How can I get the result of PROMETHEE I Ranking using the Promethee software? I want to know partial ranking and positive and negative preference flows for each alternative. Please send the solution to me. Thank you. Charles
