В этих системах предполагается зависимость между интенсивностью входного пуассоновского потока и интенсивностью экспоненциально распределенного времени обслуживания. С помощью этой зависимости строятся процедуры сглаживания пиковой нагрузки в системе. Однако для систем с детерминированным временем обслуживания такая модель и метод ее исследования непригодны. Поэтому в данной работе исследуется зависимость параметра распределения Пуассона количества заявок в системе от детерминированного времени обслуживания при наличии пика интенсивности входного потока. Эта зависимость исследована аналитически и численно, и показано, как сокращение времени обслуживания сглаживает пик количества клиентов в системе.</p></abstract><trans-abstract xml:lang="en"><p>Today, queueing systems that describe failures in the process of software testing are subject to extensive research. Such systems involve a dependence between the rate of an input Poisson stream and the rate of exponentially distributed handling time. Using this dependence, system load levelling procedures are defined. However, such a model and method of research are not suitable for systems with a deterministic handling time. Therefore, this paper examines the dependence of the Poisson distribution parameter of the number of requests in a system from the deterministic handling time in the presence of a peak rate of the input stream. This dependence is examined analytically and numerically. It is shown that a reduction of the handling time levels the peak number of customers in the system</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пуассоновский поток</kwd><kwd>детерминированное время обслуживания</kwd><kwd>система массового обслуживания с бесконечным числом приборов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Poisson stream</kwd><kwd>deterministic processing time</kwd><kwd>queueing system with an infinite number of devices</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Minamino Y., Makita Y., Inoue Sh. et al.
