摘要：The paper deals with the features of the systematic approach development, shows that the systematic approach lacks the definition of system elements divisibility. This fact simplifies the system description. The article shows that, depending on the selection of the criterion of divisibility, different types of elements with different properties are got. Depending on the selection of the criterion of divisibility, the system structure becomes multidimensional. The paper recommends to indicate the criterion of the system divisibility during the systems research. It increases the certainty of the description of a complex system and characterizes the system elements.
