The papers are devoted to new results in queueing theory and its applications,&#xa0;and also related areas of probabilistic analysis. Its target audience includes specialists in probabilistic theory, random processes, and mathematical modeling as&#xa0;well as engineers engaged in logical and technical design and operational management of data processing systems, communication, and computer networks.</span></p>
