A Man and a Collective as Elements of the Control System

The differences between mathematical models of software or hardware systems and of models of systems made of people and their collectives are described. The related problems include multi-criterion nature of a personality and a collective; conscious behaviour of elements in the system; the dynamic nature of processes in the systems and the part played by game balances in their description. It is proved that a new speciality studying the properties of people and collectives as elements of control systems should emerge.
