Decision making under risk and uncertainty - concepts, methods and applications
Project goals:
Proposing new models of uncertainty, which take some information provided with uncertainty sets into account. In particular, possibility theory and theory of imprecise probabilities will be used for this purpose. Investigating new criteria for choosing a solution, which take into account decision-makers risk aversion.
Application of various models of uncertainty to single and two-stage versions of particular problems, for example, scheduling, supply chain, production planning, and combinatorial problems. Constructing mathematical programming reformulations for these problems, implementing them and testing, by using available software. Constructing approximate solutions for hard large-scale problems.
