Risk and usefulness of situations and processes

Random variables, which sets of values represent sets of values of factorial and productive signs, are used for a situation (process) description in the article. For a discrete case, these sets have vector description allowing using such characteristics for situation setting as length of the vector describing it and a deviation angle from the fixed optimum situation. The vector description allows measuring, comparing, classifying situations (processes) from the point of view of preference and equivalence, as well as carrying out their linear transformations. On the basis of factorial and productive signs, the definition of a portfolio of situation (process) is given; the ways of its optimization are specified.
