The Lamsade is a French laboratory located in the Paris Dauphine University and it was created by Bernard Roy in 1976. About 70 employees work for this laboratory and six masters (of which two are research-oriented) are associated with the Lamsade. Two main research topics are the computer science and operations research. LAMSADE is a center established in 1974. The original research themes of Decision Support and Operational Research were then supplemented by Decision-making Informatics, Decision Theory and Artificial Intelligence. LAMSADE offers solutions for the design, use and validation of formal Decision Support models. Our research begins at the beginning of the decision-making process. It involves the extraction, learning and modeling of data, values, preferences, design of methods and systems (which can show a certain autonomy and / or intelligence) To the study of the underlying algorithmic aspects, and end up with the validation and insertion of recommendations in real organizational contexts. LAMSADE is applied to a wide range of fields such as transport planning, scheduling, tender evaluation, comfort in train cars, social acceptability of new technologies, Hydrogen and telecommunications networks. In all these fields, he is among the leaders at the international level. LAMSADE is known to be at the origin of a unique approach in the field of multicriteria decision support, for its approach to algorithmics and optimization and for the creation of the domain of the Algorithmic Decision Theory. The research carried out within LAMSADE is applied to a wide range of fields such as transport planning, scheduling, tender evaluation, comfort in train cars, social acceptability of new technologies, Hydrogen and telecommunications networks.
