ABSTRACT

Introduction. The problems of diagnostics and testing of the operation accuracy of control system communication elements are solved in this paper. It is shown that the completeness of a test set and the correctness of decision making based on testing results are greatly determined by the adequacy of the diagnostic model of an object. The purpose of the work is the development and research on diagnostic models of control system communication elements. It is necessary to propose the representation of the object under test as well as to select and apply the mathematical apparatus for the description of the diagnostic model. Results. The approaches to complex technical object modeling have been analyzed; examples for the considered domain have been given. The development of the representation of the object under test for operation accuracy testing has been carried out. The hierarchical structure of the diagnostic model based on the requirements for control fields ITU-T (FCAPS) for elements and communication systems has been proposed. The possibilities of the application of the mathematical apparatus of deterministic (Boolean, multivalued) logic and fuzzy logic for the description of the chosen fault model have been analyzed. Conclusion. The proposed diagnostic models of the operation verification of control system communication elements have been tested as a part of dataware and software of the testing automated system. They are implemented either as a separate application (technological tester) or as a part of monitoring and communications equipment management systems.
