INVESTIGATION OF TRANSIENT PROCESSES IN TECHNICAL SYSTEMS, DESCRIBED BY QUEUEING MODELS
Introduction. Complex systems, working in different fields of engineering, often function by type of queueing systems. For their investigation it is possible to use both analytical and simulation methods of modeling, which are well-known. However, it is mainly true of the modeling of a steady-state regime. As a rule, based on its results, main design solutions are made, because the investigation of transient processes is connected with certain mathematical and technical problems. At the same time, ignoring a transient regime of work, arising in technical systems because of the natural rhythm of their functioning, in some cases, can lead to considerable decrease of model accuracy. The purpose of the work is further development of scientific and methodological approaches to the design of complex technical systems and transient processes that occur in them. The methods of analytical and simulation modeling, applied for the investigation of transient processes are shown in the article by example of information systems. The results of modeling are presented as well, they allow estimating the character of these processes (their form, duration, deviation from steady-state values). Conclusion. The analysis of the results of modeling and the investigation of transient processes in considered technical systems show that, in a number of cases, when designing similar systems and determining output values of their functioning, taking into account the influence of these transient processes is compulsory. The applied method of modeling is universal and it allows investigating the singularities of transient processes in technical systems of diverse applications and structures.
