Analysis of the approaches to the estimation of technical systems’ dependability
It is given the classification of properties which compile the technical systems’ effectiveness: dependability, economical effectiveness, safety. The comparative analysis for the definitions “dependability” in accordance with standards GOST 27.002 - 2015 and GOST 27.002 - 2009 was carried out. It was shown that both for technical systems and means of technological equipment the estimation of dependability was interpreted in different ways. It was stated that estimation of dependability for operated technical system was necessary for its construction improvement and prediction of its development. Because dependability of the technical system is carried out on the stage of its design the basic stages of this procedure were described. The structural scheme of the technical system “steel sheet hot rolling process” was presented. The basic aim of this technical system functioning is to obtain hot rolled steel sheet with preseted set of properties that is why the estimation of this technical system dependability is the important aim for manufacturing process. Calculation formula of working capacity criteria for technical system dependability complex estimation were presented.
