In 2021, the International Conference "Advanced Applied Energy and Information Technologies" (ICAAEIT-2021) was held, during which leading scientists from all over the world presented their practical achievements in various fields of science and technology together with a combination of modern trends in the field of information technologies. The positive effect of such a combination became the reason for holding CITI-2023 and CITI-2024, which is a logical continuation of the mentioned International Conference "Advanced Applied Energy and Information Technologies". The implementation and use of the latest achievements in the field of computer information technologies in various fields of industry is particularly relevant today throughout the world and in Ukraine in particular. Today, such fields as automation, electronics, and medical devices are closely intertwined and cannot develop without information technologies that ensure the creation of cyber-physical systems of virtual and augmented reality, control of physical processes, creation of intelligent systems, involvement of Internet technologies, etc. The listed fields (and many others) are defined by the concept of "Industry 4.0", which is the leading trend of the "Fourth Industrial Revolution" currently taking place. At the same time, for "Industry 4.0" the basic is application of such technologies as: Internet of Things (IoT), Digital Ecosystems, Big Data Analytics (Data Driven Decision), Complex Information Systems (are described in detail below). Actually, the coverage and discussion of the latest scientific achievements in these four directions, which combine modern technical achievements with information technologies for "Industry 4.0", is the main goal of CITI-2024.
