Abstract

The following paper presents the problem of classification (identification) elements in the internal structure of a technical object. This problem is directly linked with diagnostics and compilation of an expert data base. The basis of a process of grouping elements into classes is to make a diagnostic model of a given object in a form of a structure or set of basic elements of an object. In order to conduct the grouping of elements into subsets of s-th classes, the following paper compiles and presents analytical formulas and classification rules. Theoretical considerations presented in this paper are also verified using an engine control system as an example of a complex technical object.
