The book "Economic and mathematical models and their application in agriculture" by N. In. Speshilova is a fascinating and in-depth study that opens up new horizons in the field of agro-industrial complex (AIC) through the prism of economic and mathematical methods. In the face of modern challenges, such as climate change, fluctuations in agricultural prices and the need for sustainable development, this work becomes especially relevant and valuable for specialists in the field of agriculture, economics and mathematics. Speshilov, possessing rich experience and deep knowledge in his field, offers the reader not only theoretical calculations, but also practical examples of the application of economic and mathematical models in the agro-industrial complex. The book covers a wide range of topics, including optimization of production processes, cost-benefit analysis, as well as forecasting market trends. The reader will be able to learn how to use mathematical methods to effectively manage resources, minimize risks and increase the profitability of agricultural enterprises. This book will be of interest not only to professional economists and agronomists, but also to students, graduate students and anyone who seeks to deepen their knowledge in the field of agronomy and economics. It is suitable for those who are looking for practical tools to solve real problems, as well as for those who want to understand how mathematics can become a powerful tool in the management of agro-industrial production. The age category of readers is not limited, but it will be especially useful for young professionals and senior students. The topics raised in the book cover important aspects of sustainable development, resource management and the introduction of innovative technologies in the agricultural sector. In the context of globalization and rapid technological progress, the use of economic and mathematical models becomes not only desirable, but necessary to achieve competitiveness. Readers will be able to see how modern methods of analysis and forecasting can help in making informed decisions, which certainly makes the book worthy of attention. The author's style is distinguished by clarity and accessibility of presentation, which allows even complex mathematical concepts to be perceived easily and at ease. N. In. Hashilov is the author of several other well-known works on economics and mathematics, which testifies to his deep understanding of the subject and the ability to convey information to a wide audience. His approach to teaching and research has always been focused on the practical application of knowledge, which makes every page of the book valuable to the reader. If you are looking for literature that will help you understand the complex issues of the agro-industrial complex and teach you how to use mathematical models to solve practical problems, then “Economic and mathematical models and their application in the agro-industrial complex” will be an excellent choice. This book will not only expand your horizons, but also equip you with the necessary tools for successful work in the dynamically developing field of agriculture. Do not miss the opportunity to touch the world where economics meets mathematics, and discover new opportunities for growth and development in the agro-industrial complex.
