Knowledge Bases and Decision Support in CAD . At 3 p.m.. H. 2" by Viktor Alexandrovich Kochurov is a fascinating and in-depth study that immerses the reader in the world of computer-aided design (CAD) systems and their intellectual capabilities. The second part of this three-volume edition continues to reveal important aspects of the creation and use of knowledge bases, which become an integral part of modern engineering solutions. Victor Kochurov, known for his scientific work and practical experience in the field of design and automation, offers readers a unique look at how knowledge bases can significantly improve the decision-making process in complex design tasks. This book will be of interest to both students and graduate students of technical specialties, as well as practicing engineers, designers and managers seeking to optimize their work processes. In the second part of the book, the author delves into the theoretical and practical aspects of creating knowledge bases, examines the methods of their integration into CAD and discusses how these systems can support decision-making in conditions of uncertainty. The reader will find many examples and cases that illustrate how the use of knowledge bases allows not only to speed up the design process, but also to improve its quality. Kochurov focuses on the importance of proper organization of information and its structuring, which is key for effective work with data. The topics raised in the book are extremely relevant in light of the rapid development of technology and the requirements of the modern market. With the ever-increasing complexity of project tasks and the need to respond quickly to changes, having a reliable knowledge base becomes not just desirable, but a prerequisite for successful work. The book emphasizes that the competent use of intelligent systems not only makes life easier for engineers, but also contributes to the creation of more innovative and high-quality products. Kochurov’s style is distinguished by clarity and accessibility, which makes his work understandable even for those who are just beginning to get acquainted with the topic of CAD and knowledge bases. His previous works, such as Intelligent Decision Support Systems and Design Automation, have already won recognition among professionals and students, and the second part of this book will not disappoint readers. The author masterfully combines theory with practical examples, which allows a deeper understanding of the issues under consideration. This book will be a real find for those who are interested not only in the technical aspects of design, but also in how modern technologies can change the approach to solving complex problems. It will be useful both for students studying engineering disciplines and for experienced professionals seeking to expand their knowledge and skills in the field of automation and intelligent systems. If you are looking for literature that will help you understand the intricacies of CAD and knowledge bases, and will also teach you how to put this knowledge into practice, "Knowledge Bases and Decision Support in CAD. At 3 p.m.. H. 2" will be your reliable assistant. Do not miss the opportunity to immerse yourself in the world of modern technologies and discover new horizons in design!
