The workgroup are going to have contacts with scientists from different countries who are connected with the problems of Modeling of Risk situation.

We state foundations of logic and probabilistic (LP) risk theory of multicomponent systems with groups of incompatible events (GIE) for problems of classifications (credit risks), investment (security portfolio risk), effectiveness (analysis of social processes) and management companies (country or city administration).

In named problems, having different statement of tasks of optimization, we use arbitrary distributions of random variables given discretely. This allows us to use for modeling and analysis of risk the LP-calculus, to overcome the many of weakness and assumptions of traditional methods and to get essentially bigger accuracy, robust and transparency in estimates of non-success risk.
