The book "Indistinct hybrid systems. Theory and Practice", written by a team of authors led by I. Z. Batyrshin, A. About. Undersea and A.......................................... A. Stetsko, is a fascinating and in-depth study of fuzzy logic and its application in modern control systems. This publication will be a real find for students, graduate students, researchers and practitioners interested in advanced technologies in the field of artificial intelligence and automation systems. The book focuses on fuzzy hybrid systems that combine elements of fuzzy logic and traditional control methods. The authors examine in detail how these systems can be used to solve complex problems where traditional approaches prove to be ineffective. The reader will be able to learn about the principles of constructing fuzzy models, their advantages and disadvantages, as well as how to integrate such systems into existing technological processes. The book covers a wide range of topics, ranging from the basics of fuzzy logic to practical examples of the use of hybrid systems in various fields, such as robotics, medicine, economics and management. The authors share their experience and knowledge, which allows the reader not only to understand the theoretical aspects, but also to see how these concepts work in practice. As a result, Fuzzy Hybrid Systems becomes not just a textbook, but a real guide to the world of modern technologies. This book will be especially interesting for those who are fond of mathematics, computer science and engineering sciences. Technical students, graduate students and young scientists will find in it useful knowledge and inspiration for their research. Practitioners working in the field of automation and management will be able to use the acquired knowledge to optimize their processes and introduce innovative solutions. The style of the authors is distinguished by clarity and accessibility, which makes complex concepts understandable even for those who are just beginning to get acquainted with the topic. The book is filled with illustrations, examples and practical tasks, which allows the reader not only to absorb the material, but also to apply it in practice. This makes Fuzzy Hybrid Systems an excellent choice for those who value quality and up-to-date literature. In addition, in the context of current trends in artificial intelligence and big data, the book raises important questions about the future of technology and its impact on society. The authors emphasize the need to develop hybrid systems capable of adapting to rapidly changing conditions and requirements. This topic is becoming increasingly relevant in light of the rapid development of technologies and their integration into everyday life. If you are looking for literature that will help you understand the complex issues of fuzzy logic and hybrid systems, "fuzzy hybrid systems. Theory and Practice" will become your reliable assistant. With this book you will be able not only to expand your knowledge, but also to gain practical skills that will be useful in your professional activities.
