The article presents a simulation model of a queuing system (QS) with a queue and relative priority, which can be used to manage the reliability of transport systems under resource constraints. The developed simulation model combines agent and discrete-event simulation principles and allows studying queuing systems in terms of establishing regularities: probabilities (service, failure, push-out), time delays (waiting in a queue, under service), queue sizes, order of queue formation upon arrival of clients of different priority. As a result of the research, dependencies were obtained for the probability of servicing higher priority clients depending on the intensities of their arrival and service; probabilities of servicing lower priority clients depending on the intensity of service and servicing of higher priority clients; the probability of "pushing out" lower priority clients from the QS by higher priority clients depending on service intensities and the arrival of high priority clients.Downloads
