In studying interrelated problems in various branches of science and engineering, as well as economic activity. the "system" concept, "systems approach." and "systems analysis" are widely used.Systems approach and systems analysis are methods of constructing complex economic-organizational and engineering systems under conditions where the associations that permit solution of economic problems, which cannot be described in full by mathematical relationships, are uncertain. They are. however, subject to analytical analysis, which makes it possible to substantiate reliably the solutions adopted by managers. A characteristic feature of the systems approach consists in the fact that it can be applied to units that are partly nonmaterial and e~tremely heterogeneous. For example, a systems analysis of the operation of an establishment may include people, machines, buildings, stock deliveries, production output, and even personnel initiative, resulting in an optimal relationship between these elements in the interest of established business.
