Instrumental support for constructing and using system-object three-dimensional classification

The article discusses the problem of instrumental support for construction and use procedures using the system-object approach of three-dimensional classification (SO3K). The possibilities of forecasting and management support using CO3K are shown using specific examples. The results of a study of the existing tools for conceptual classification modeling (ontological engineering) are presented, showing that with its help it is impossible to ensure the construction and use of CO3K. In order to create instrumental software that supports the construction and use of CO3K, a set of functional requirements for it has been developed in the form of a UML diagram of use cases (precedents) and activity diagrams as event flows for them.
