STD to 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 by Makhutov et al. (2016). Proceeding from the tasks solved by STD, it is possible to formulate the following main directions and conditions of formation of effective systems of technical diagnostics (see fig. 1).Concrete techniques of assessment of effectiveness of STD substantially depend on branch accessory of an object of diagnostics. Objects of defense industry, railway transport and methods of diagnostics of provable medicine can be examples. The formulated main directions and conditions for the formation of effective systems of technical diagnostics reflect solutions of primal problems of assessment and increase in effectiveness of STD. The best results at the same time can be achieved only on the basis of complex increase in target effectiveness of all STD elements defining quality of its functioning. 5. Conclusions So far in a number of the industries the practical experience of the quantitative assessment of effectiveness of STD including determination of their cost efficiency and also calculation of various indexes characterizing quality (target effectiveness) of technical diagnosing is accumulated. At the same time the number of questions demands specification and a further research. This refers primarily to differences in approaches to assessing the effectiveness of newly created and functioning STDs that need modernization. In the first case, the indexes discussed above can be applied (taking into account industry specifics). For functioning STDs, the choice of directions and conditions for increasing their effectiveness as applied to the main tasks solved by STDs becomes decisive. The issues related to the use of a generalizing parameter (function, functional) of the effectiveness of STDs are also insufficiently investigated. In this area, the use of fuzzy logic methods and models opens up new possibilities. References Akhmetkhanov R.S., Dubinin E.F., Kuksova V.I., 2016.
