System-Object Classification Modeling of Complex Subject Areas

Abstract

The paper deals with the problems of the theory of classification and the shortcomings of modern classifications. An original method for constructing three-dimensional classifications is described, which makes it possible to eliminate the mentioned shortcomings. The proposed method is based on a system-object approach using the ideas of multidimensional classification and natural classification. Three main system characteristics are used as classification planes: structural (“unit”), functional (“function”) and substantial (“object”), which allows classification by types of functional request to the system, by types of system formation processes and by obtained results. results. Each classification is a tree-type graph with one vertex that is common to all three planes. Each classification graph consists of two parts: the classification of the corresponding objects and the classification of the properties of these objects, which are isomorphic to each other, which determines the parametricity of the classification as a whole. The considered method of classification allows not only to distribute the phenomena and objects of the subject area by classes, but also to trace the causal relationships existing in this area. An example of three-dimensional classification in the field of emergency situations is given. Ways of further research and use of three-dimensional classifications are outlined.
