This book includes more than 20 unique studies on the development of digitalization, technologies, innovations, and systems, as well as their application in economics, management, marketing, tourism, mechanical engineering, metallurgy, and ecology. These materials are based on discussions held within the framework of the VII International Scientific Congress ISC SAI 2024, held at the State University of Economics and Technology (Kryvyi Rih, Ukraine) from December 2 to 6, 2024. The book includes studies prepared in collaboration with representatives of higher education institutions, the scientific community, business, industry, and ecologists. The works reflect modern trends in the development of advanced technologies, artificial intelligence, mechanical engineering, engineering innovations, construction, engineering ecology, and digital transformation of the economy. Particular attention is paid to current processes and problems faced by the industrial sector, the environment, and the global economy. The book is devoted to the digital transformation of the economy—the process of integrating digital technologies into various aspects of economic activity. This leads to significant changes in the way business is conducted, value is created, and interactions with customers, partners, and suppliers are carried out. Digitalization covers the most important industries, including manufacturing, finance, tourism, trade, and transport. In the context of digitalization, enterprises need to implement flexible organizational models that ensure the ability to quickly adapt in response to changes in the market situation and technological innovations. This requires a revision of traditional hierarchies, active development of cross-functional interaction, and providing employees with greater independence in decision-making and responsibility for the result.
