**(OSGaD)**

In many domains of decision and game theory, ordered structures, partial orders as well as combinatorial structures and convex polyhedra naturally arise in the process of modelling and solving. This can be observed in, e.g., cooperative game theory, social networks, classification and pattern recognition, logical reasoning, decision making, combinatorial optimization, and other domains of operations research. Although these domains share common mathematical tools, they concern, as a matter of fact, disconnected scientific teams and manifestations. Likewise, the same mathematical concepts arise and are studied in different and independent domains, leading to similar and redundant achievements.

The aim of the OSGAD seminar is precisely to gather scientists from different fields but sharing the same mathematical concepts or techniques, as it happens, ordered structures, combinatorial structures and polyhedra. Participants should therefore benefit from new ideas, different points of view, and cross-fertilization.

The OSGAD seminar is related to the regular seminar MDOD (Mathématiques Discrètes, Optimisation et Décision), organized by Michel Grabisch, Arianna Novaro and Alexandre Skoda (see here for details).
