Reference excerpt

The French Operations Research & Decision Support Society (in French: Société française de Recherche Opérationnelle et d’Aide à la Décision - ROADEF) is a professional non-profit society that aims to promote the scientific field of Operations Research (OR) and Decision Support (DS) in France. The society is a member of the European umbrella organization, the Association of European Operational Research Societies (EURO), and of the International Federation of Operational Research Societies (IFORS).

History The society was created in 1998. Its mission is to encourage the development of operational research and decision support in France, to disseminate OR/DS knowledge and practices in industry, and to promote their teaching in education. Founding members of ROADEF included Denis Bouyssou, Jacques Carlier, Philippe Chrétienne, Stéphane Dauzère-Pérès, Dominique Fortin, Xavier Gandibleux, Nelson Maculan Filho, Ali Ridha Mahjoub, Gérard Plateau, Jean-Charles Pomerol, Marie-Claude Portmann, Christian Proust, Catherine Roucairol, Bernard Roy, as well as some OR/DS research laboratories - LAMIH (Université de Valenciennes et du Hainaut-Cambrésis), Lamsade (Université Paris-Dauphine) - and some companies practicing OR/DS - Bouygues, Eurodecision, Gaz de France, SNCF.

Governance The ROADEF society is managed by a board composed of six officers elected by the members, including the President, a secretary, a treasurer, three vice presidents, plus a special officer in charge of OR promotion and of industrial relations. The current president of ROADEF is Sandra Ulrich N'Gueveu. Previous presidents included François Clautiaux, Aziz Moukrim, Sourour Elloumi, Frédéric Gardi, Nadia Brauner, Francis Sourd, Olivier Hudry, Jean-Charles Billaut, Marie-Christine Costa, Arnaud Fréville, Denis Bouyssou, Marie-Claude Portmann.

Membership Currently (2016), the ROADEF society has more than 500 members - individuals and institutions from academia, industry and administration.

Publications Jointly with the Belgian Society for Operations Research and the Italian Operations Research Society, ROADEF publishes 4OR - A Quarterly Journal of Operations Research. The publisher firm is Springer. Every 6 months, a printed/online bulletin, Bulletin de la ROADEF, is sent to the members. It includes news, interviews and short presentations of research areas in OR/DS by scientific experts. In addition ROADEF holds the scientific responsibility of the journal RAIRO - Operations Research.

Conferences Once a year, ROADEF organizes a national conference, attended by about 400 participants (2017). ROADEF also organizes on a regular basis some industrial events to favor exchanges between academics and professionals.

Challenge Every second year, a challenge is proposed to the OR community. International research teams compete to solve at best a real-world optimization problem provided by a business company. Latest problems were proposed by Air Liquide, SNCF, Google, EDF. The winner of the competition is revealed during the EURO conference.

Awards The Robert Faure Prize awards an original contribution to the field of Operations Research and Decision Sciences with both theoretical aspects and applications. This prize is given every three years by a jury composed of academics and practitioners. Last winners included Giacomo Nannicini, Frédéric Gardi, Jérôme Malick, Walid Ben Ameur, Francis Sourd, Philippe Baptiste, Chengbin Chu, Eric Pinson, and Philippe Solot. The Jeune Chercheur Prize awards a young researcher (who has recently received her/his PhD or is still in thesis) for her/his contribution in Operations Research and Decision Sciences. The prize is awarded each year by a scientific jury during the ROADEF conference.

Worked examples

Example 1 — a first encounter with Société française de Recherche Opérationnelle et Aide à la Décision

Start with the simplest possible case. Write down what Société française de Recherche Opérationnelle et Aide à la Décision claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Société française de Recherche Opérationnelle et Aide à la Décision before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Société française de Recherche Opérationnelle et Aide à la Décision ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Société française de Recherche Opérationnelle et Aide à la Décision

In research: Société française de Recherche Opérationnelle et Aide à la Décision appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Société française de Recherche Opérationnelle et Aide à la Décision in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Société française de Recherche Opérationnelle et Aide à la Décision is common in secondary-school and first-year university syllabi.
