title: [About the modeling of developing systems].
abstract: The purpose of the communication is to discuss the general properties of developing systems, the methods of their modeling, and the question of their complexity. The concept "complex system" is conditional, a more precise meaning has the complexity of the model describing the phenomenon. Two propositions are discussed: (1) The complexity of basic models is minimal. In other words, complex basic models are not necessary at all. (2) Alive systems are simpler than lifeless. Many processes in the inanimate nature, too, can also be assigned to developing systems. Nevertheless there is a distinction between alive and lifeless systems. The distinction consists in that alive beings can put a purpose before themselves and develop according to it. For this reason, they can be described by simpler basic models.
