Item Estimation of indexes of efficiency of radioelectronic hardware-software systems based on the algorithm behavior(Видавництво Львівської політехніки, 2012) Volochiy, Bohdan; Ozirkovskyy, Leonid; Shkiliuk, Oleksandr; Mashchak, AndriyIn this paper the technique of building models of radioelectronic software-hardware system with regard to quality of service information network is presented. Building a model involves the development of structural-automatic model,which is the input data for software module ASNA, in automatic mode generates a graph of states and transitions and creates a system of Chapman-Kolmogorov differential equations for different sets of input data.Item Availability determination for renewal load-shared tree structure systems(Видавництво Львівської політехніки, 2012) Shcherbovskykh, SerhiyIn the paper the method and models for renewal load-shared tree structure systems availability determination are discussed.Item Models for estimation downtime of a systems with redundancy and maintenance(Видавництво Львівської політехніки, 2012) Ozirkovskyy, Leonid; Panskyi, Taras; Sydorchuk, AlexanderThe object of consideration is fault-tolerant radioelectronic system with redundancy and maintenance without automatic replacement of modules that are out of order. A structural-automatic model for such systems, which allows to determine the reliability indexes of such systems is developed.Item Models of fault-tolerant systems with reconfiguration of the core of structure of “K of N”(Видавництво Львівської політехніки, 2012) Volochiy, Bohdan; Ozirkovskyy, Leonid; Zmysnyi, MykhailoModels of fault-tolerant system with a combined structural redundancy, which includes the structure of “K of N” with Nth number of technical systems in the core and their sliding redundancy are presented. Exploitation of system does not provide for maintenance and therefore the using procedures of reconfiguration of the core of structure of “K of N” are examined. Possibilities of models researching two variants of realization of the procedure reconfiguration of the core of structure of “K of N” are demonstrated.Item Automation of building of behavior models of the non-markov discrete-continuous stochastic systems by the method of erlang phases(Видавництво Львівської політехніки, 2012) Volotchiy, Bohdan; Osirkovskyy, Leonid; Kulyk, IhorThe construction of models of behavior of discretecontinuous stochastic systems Non-Markov type by the method of Erlang phases is the object of consideration. This paper shows the principles of improving the technology of building the models of discrete-continuous stochastic systems, that allows you to build automated graph of states and transitions of Non-Markov type systems with using the method of Erlang phases. Improved technology is illustrated by the example of a queuing system.Item Reliability analysis of technical systems without redundancy with limited number of repairs(Видавництво Львівської політехніки, 2012) Bobalo, Yuriy; Mandziy, Bohdan; Volochiy, Bohdan; Osirkovskyy, LeonidThe object of consideration is the construction of analytical models non-redundant maintainable system with a limited number of repairs. On the basis of the constructed model the analysis of reliability indexes - availability and the probability of downtime is carried out.Item GTU tests results monitoring system(Видавництво Львівської політехніки, 2012) Shitikova, Yelena; Tabunshchik, GalinaThe paper deals with the problems of reliability and safety of the gas turbine units for terrestrial usage. Monitoring system of GTU tests results was developed by the authors.Item Content and modern trends of reliability aspect in radioelectronic designing(Видавництво Львівської політехніки, 2010) Bobalo, Yuriy; Mandziy, BohdanThe article deals with modern development trends and the content of the problems concerning reliability aspect of radioelectronic device designing at the different hierarchic designing levels.Item Failure intensity determination for renewal doubling system with parallel redundancy(Видавництво Львівської політехніки, 2010) Lozynsky, Orest; Shcherbovskykh, SerhiyThe problem of failure intensity determination for renewal doubling system with parallel redundancy is considered.Item Approach to the complex estimation of factors, Influencing on communication networks’ reliability(Видавництво Львівської політехніки, 2010) Nenov, AlexeyIn this paper the classification of factors influencing the reliability of communication networks is given. The approach to the factors complex estimation on the basis of mechanism of petalous diagrams is offered.
