Volodymyr L. Analysis of reliability indexes of aggregate of facilities of measuring technique in the conditions of wide industrial application

Dissertation is devoted to research and improvement of methods of the automated decision of tasks of estimation and operating security analysis of measuring instrument (MI), and also to optimization of parameters of the system of metrological maintenance system MI (MMS). On the basis of discretely-continuous approach new dependences are got and communications are set between complex reliability indexes and parameters of MMS MI at entrance diffusive (DM and DN -distributive) metrological failure patterns and exponential distributing of probability of origin of obvious refusal. The method of the graphic scanning at the choice of optimum parameters of descriptions of reliability and period of maintenance is offered. On the basis of technologies of programming of informative networks the general method of synthesis of the programmatic is modulated for the decision of tasks of security analysis and optimization of parameters of MMS MI. On the basis of the improved method of reliability analysis of MI software and recommendations are created for using the program module which includes the following functions in work: estimation of the actual state of MI at actual time at the fixed descriptions of reliability and MMS MI; analysis of dependences of reliability indexes on the parameters of MMS MI; optimum choice of service period, or optimum combination of parameters of MMS MI after the criterion of minimum of total charges on MMS MI and losses from application of MI with the metrological refusal, at limitations of the production system on the technical and metrological constituent of MI.
