Welcome to e-PROMETHEE Days 2020

April 14th, 2020

All members of the PROMETHEE Days 2020 SC and OC wish to express their support and friendship to the entire PROMETHEE Community. Let us stick together (but not too close…) during these difficult times.

The current health emergency situation makes it impossible to maintain our meeting as foreseen in Rabat on June 2-4:

Containment and travel restrictions will most certainly continue at least through May. Even if it were possible to travel to Rabat in June, many people will probably prefer to recover and to avoid international travel.

We are no losers either and we will not cancel a meeting including 39 top-class contributions.

Instead, PROMETHEE Days 2020 turns to e-PROMETHEE Days 2020.

What does it mean?

Please check the www.prometheedays.com web site for updates (fees, organization, award, …). And join us on the e-PROMETHEE Days 2020 Forum at forum.promethee-gaia.net

Let’s stick together

March 26th, 2020

Dear friends,

We are all facing difficult times that have a strong impact on our personal and professional lives. And we don’t know how the situation will evolve during the next weeks/months.

I sincerely hope that all of you, your families and your friends, are well. It would be nice for all the members of our community to know that you are safe. Please don’t hesitate to share information and news through the PROMETHEE Methods LinkedIn group at https://www.linkedin.com/groups/3956394/

I will be very happy and reassured to receive news from you.

With respect to the organization of the PROMETHEE Days 2020 meeting (which is much less important than our health), the Scientific and Organizing Committees are waiting until the end of the month to reassess the situation.

Please take care.

Best regards,


PROMETHEE Days 2020: the next step!

March 18th, 2020

The abstract submission deadline is over.

We still expect a few late submitters, but the current state is an all-time record with 39 papers from 14 countries spread over 4 continents.

We are now starting to finalize the program.

We hope that the current international health emergency will not affect our meeting. We are still 2.5 months away from Rabat and we are continuously monitoring the situation.

Flying to Rabat on February 24

February 15th, 2020

I will be in Rabat from February 24 to 28 with a busy schedule:

Do not forget the abstract submission deadline for the PROMETHEE Days 2020 meeting. We are expecting your abstract proposals by March 1st, two weeks from now!

Check http://www.prometheedays.com, submit your abstract, join us in Rabat in June, and compete for the 7th JPB PROMETHEE Award.

Outranking & Decision: a new open journal

January 30th, 2020

A new journal is now available to members of the multicriteria outranking community.

Outranking & Decision (O&D) is an open journal: it is managed by scientists for scientists, without any commercial publishing company involved. It is published in electronic format only and is available free of charge to all authors and readers. The Editorial Team includes 22 specialists in multicriteria decision aid.

O&D welcomes papers related to outranking methods and decision aid. All papers will be peer-reviewed by at least two qualified referees to ensure a high-quality level for the journal. The first issue is expected in 2020 and will include post-proceedings of the PROMETHEE Days 2020 meeting.

More information and instructions for paper submission are available at:


Merry Christmas and a Happy New Year 2020

December 13th, 2019

As we are getting closer to the end of 2019, it is a good time to look back at what happened in 2019:

  • The PROMETHEE Days 2019 meeting took place in Split on May 22-24. It was a success thanks to the wonderful organization by our Croatian colleagues.
  • New links have been established, especially with colleagues from Asia:
    • I have been visiting and giving lectures in several universities in Taipei (Taiwan) in May.
    • Professor Mandeep Kaur (India) was attending the Split meeting and we are developing scientific collaboration.
    • More recently, I have developed very promising contacts with Palestinian colleagues.
    • There is a large PROMETHEE-related scientific activity in Asia and it is important to strengthen our links with our colleagues from this region.

What can we expect for 2020?

  • The PROMETHEE Days 2020 meeting will take place in Rabat (Morocco) on June 2-4. This will be our first meeting in Africa. Please check the www.prometheedays.com web site for more information. The abstract submission deadline is March 1st, 2020.
  • Several important announcements will be made in 2020:
    • We have been (and still are) working hard to make it easier for PROMETHEE Community fellows from all regions (Asia, North America, South America, Africa, Oceania, Europe) to meet and to exchange information.
    • Physical meetings such as the PROMETHEE Days are important to establish social links.
    • The publishing of papers is also important to transmit knowledge and experience.
    • Stay tuned:

I wish you a Merry Christmas and a Happy New Year.

I am looking forward to meeting you on LinkedIn, on Twitter, or in Rabat next June!

PROMETHEE returns to Greece!

May 8th, 2018

Born in 1982, now 38 year-old, PROMETHEE is returning to the land of his ancestors: Greece… well, actually Crete!

The PROMETHEE Days 2018 workshop will take place in Heraklion on May 22-25, together with the ICDSST 2018 meeting of the EURO Working Group on DSS.

It will certainly be a very nice meeting with a PROMETHEE Days stream including 17 papers, 2 invited speakers and a panel discussion on “Ethics & Decision”.

If you want to join us in Heraklion, or if you are interested to attend or organize one of the next PROMETHEE Days workshops, please check the website:

Spring 2017

March 19th, 2017

Bye bye Winter! Two days left!

It was not visible on the blog but this Winter has been intensive and time has run so quickly…

  • PROMETHEE Days 2017 are approaching. The programme will be available soon and I will be very happy to meet you in Portsmouth (UK) on May 11-12. Check the website http://www.promethee-days.com for information and registration.
  • ICDSST 2017 will take place in Namur (Belgium) on May 29-31. It is the meeting of the EURO Working Group on DSS and it will have a special PROMETHEE flavor this year as Jean-Pierre Brans will give a plenary lecture on PROMETHEE, MCDA and Ethics. Visit the website for more information: https://icdsst2017.wordpress.com
  • PROMETHEE has moved (well… at least I have) to a new house in the countryside called Wallifornia, South of Brussels. It has taken a lot of time to unplug, to pack, to move, to drill, to paint, to unpack, to plug, … and it is not finished yet… but I am writing this post from the new PromCave, right under the PROMETHEE Mansion. Villains beware, the Prom Knight is back to Brussels City. 😉 Which means that computers are on. Stay tuned for software development on http://www.promethee-gaia.net
  • Still  looking for a new more reliable PromMobile… Suggestions welcome at mailto:bmaresc@ulb.ac.be

Don’t forget the other information channels for the PROMETHEE Community:

  • On the PROMETHEE website: http://www.promethee-gaia.net
  • On Twitter: @bmaresc to follow me and @prometheedays for specific PROMETHEE Days information.
  • On LinkedIn: you are welcome to connect with me and with the close to 200 members of the PROMETHEE decision aid methods group.

Best regards,
