Abstract Three theoretical principles of developing the diagnostic support for technical objects of diagnosis are formulated, namely: the principle of dominance - knowledge about the set of possible defects of the diagnosis object is dominated by all other types of diagnostic knowledge; the principle of five systemic representations of the diagnostic object - in the problem of finding defects with maximum depth, in the general case, knowledge of the external, degradation, and structural representations of the diagnostic object is necessary; compliance principle - the operational reliability of the diagnostic object is to be supported by an effective maintenance system corresponding to it. The main goal of the work is to establish the interdependence between these principles. In addition, the listed principles are analysed in relation to the main diagnostic tasks and various classes of technical objects of diagnosis, and are also recommended for use in the development of diagnostic support for technical systems, including the development and maintenance of the diagnostic expert systems.
