System researches - new approach

System researches generated the grate volume of publications, but proved to be not efficient in science since the notion "system" was indistinct and included too wide class of objects. The new concept of a system, as an object with self-maintenance is introduced. It is shown that such approach is more useful to the effective organization of transport junctions.
Key words: system, object, self-maintenance, presystem, dynamic reserves, complexity
