Peer-review under responsibility of the ILEE-2019 organizers Keywords: system of technical diagnostics; efficiency of diagnosing; quality of technical diagnosing; cost efficiency of system of technical diagnostics The growing importance of systems of technical diagnostics as an integral element of complex technical systems, determine the need of developing an assessment methodology and improve the effectiveness of systems of technical diagnostics themselves. Generally assessment of the impact of systems of technical diagnostics on results of functioning of an object of diagnostics can be received by comparison of indexes of efficiency of an object of diagnostics without the system of diagnosing and with the system of diagnosing. In practice the cost efficiency of the systems of technical diagnostics and various indexes characterizing quality of technical diagnosing are usually calculated. In a general view, the "contribution" of the system of technical diagnostics to decrease in an accident risk and risk from operation of the object of diagnostics can be estimated on the basis of the functional, accounting the reduced cost of creation and functioning the system of technical diagnostics and the direct losses caused by risk of accident (refusal) of the system of technical diagnostics. The inefficiency of the system of technical diagnostics is, as a rule, caused by discrepancy of its parameters with the tasks solved by it; these tasks are: development of algorithms of diagnosing, forecasting of change of technical condition, development of methods and diagnostic devices. This made it possible to formulate some main directions and conditions for the formation of effective systems of technical diagnostics. Th growing import ce of ystems of technical diagnostics as an int gral el ment of co plex technical systems, de er ine the n ed of developing an ass ss ent methodology and improve the effectiven s of systems of technical diagn stics themselves.
