The book "Mathematical methods and models of operations research" by Adamchuk A. C. This is a fascinating and deep dive into the world of mathematical modeling and optimization, which will be a real discovery for both students and professionals working in the field of management, economics and engineering. This work is not just a textbook, but a whole encyclopedia of knowledge that will help readers to master complex concepts and apply them in practice. In his book, Adamchuk offers readers a unique perspective on operations research methods that play a key role in decision-making under conditions of uncertainty and limited resources. It covers a wide range of topics, ranging from basic concepts of linear programming to more complex models such as dynamic programming and game theory. Each chapter is imbued with practical examples, which makes the material accessible and understandable, even for those who are just beginning to get acquainted with this area. The book will be of particular interest to students and graduate students of technical and economic specialties, as well as specialists working in the field of logistics, project management and data analysis. If you want to improve your skills in making informed decisions and want to learn how to use mathematical models to solve real problems, then this work will become an indispensable assistant for you. One of the key topics raised in the book is the importance of a mathematical approach in the modern world. Adamchuk shows how mathematical methods can not only improve business efficiency, but also help in solving social and environmental problems. In a rapidly changing world, where data is becoming the new gold, the ability to analyze and interpret them with mathematical models becomes especially relevant. Adamchuk's style is distinguished by clarity and logical presentation, which allows the reader to easily assimilate even the most complex concepts. He masterfully combines theory with practice, which makes the book not only a textbook, but also a practical guide for applying knowledge in real life. In addition, the author actively uses graphic illustrations and diagrams, which greatly simplifies the understanding of the material.
