The book "Practice on the computer on the theory of mass service" by Dudin, Medvedev and Melenets is a fascinating and deeply developed manual that immerses the reader in the world of mass service theory (TMO) with the help of practical tasks and computer simulations. This work is intended for undergraduates, graduate students, and anyone interested in applying mathematical techniques in the management and optimization of customer service-related processes. Mass service theory is an area that studies how to organize effective service in a variety of systems, from queues in stores to data flows in computer networks. In the book, the authors offer the reader not only theoretical knowledge, but also practical skills that allow you to apply this knowledge in practice. Each section contains tasks that can be solved with the help of electronic computers, which makes the learning process interactive and exciting. Who can like this edition? First, it will be useful for students of technical and economic specialties studying disciplines related to management, logistics and optimization . Secondly, the book will interest graduate students and young professionals working in the field of information technology, system analysis and quality management. Finally, the workshop will be useful to anyone who wants to improve their skills in mathematical modeling and data analysis. The main topics raised in the book include analysis of service systems, modeling customer flows, assessing the effectiveness of service systems and optimizing processes. The authors emphasize the importance of a mathematical approach to solving practical problems, which makes the book especially valuable for those who seek a deep understanding of the processes occurring in modern service systems. The style of the authors is distinguished by clarity and accessibility of the presentation, which makes it easy to assimilate even the most complex concepts. Dudin, Medvedev and Melenets are experienced specialists in their field, and their knowledge and skills are reflected in every page of the book. They are also the authors of other well-known works on mathematical modeling and probability theory, which confirms their authority in the scientific environment. Readers interested in search queries such as "mass service theory", "mathematical modeling", "process optimization", "queue theory workshop" or "service quality management" will find many useful information and practical examples in this book. The book not only expands the horizons of knowledge, but also inspires the application of the acquired skills in real life. In conclusion, the Computer Practice on Mass Service Theory is not just a training manual, but a real find for anyone who wants to understand complex maintenance processes and learn how to effectively manage them. This book will become a reliable companion on the way to professional growth and development in the field of management and optimization, opening up new horizons and opportunities for the reader.
