The additive economy should be the productive basis toward which the national economies aspire. This paper aims to deepen the theoretical issues of the additive economy forming and its key components: additive technology and additive manufacturing. Additive technology is defined as a set of methods and tools based on which the production of products occurs by adding only the useful part of natural substances to the final commodity and creating no waste. Additive manufacturing is a system of interconnected processes of transforming natural substances into finished products based on additive technology. The additive economy is a system of trade and industries based on additive manufacturing. The study analyzes competitive advantages (direct prototyping, saving materials and energy, the ability to work without human participation, dematerialization of transportation and storage of products) and challenges of the additive economy (building an organizational network of production systems; forming solidarity economy; developing new social institutions; social development of a person). The paper formulates the key directions of economic systems restructuring to an additive economy formation, including restructuring energy production types, energy networks, and interface sphere and change of the structure of primary resources. The general debatable problem of the economic systems restructuring to the additive economy is the formation of new social institutions capable of providing necessary solutions.

The relevance of the study is due to the growing need to use chatbots to optimize business processes. The purpose is to form a theoretical basis and practical tools for increasing the efficiency of using chatbots in business processes. The theoretical basis involves substantiating the theoretical foundations of forming a conditional chatbot profile for an optimization system. The practical toolkit includes chatbot components that depend on the complexity of tasks, the type of services, the specifics of customers, financial conditions, and other features of business processes. The result is the formation of a system profile of the chatbot, which would allow increasing the efficiency of its use in business processes. The key system components of the chatbot are substantiated: the technologies used, types of users, optimal areas of application, application algorithms, basic tools, and limitations in application. By varying the parameters of system components, one can choose their optimal values to increase the efficiency of using chatbots in business processes. It is advisable to use the specified system in business processes when determining the demand for products and their sales. The use of chatbots allows to reduce the time to complete business processes, personnel costs, and resources related to their implementation.

The rise of local and global challenges (such as COVID-19, wars, natural disasters, etc.) requires advanced communication and information technologies to support economic development. The study aims to form a theoretical basis and practical tools for creating and functioning of wiki communities. Wiki communities are a new form of social association based on Internet communications of socio-economic subjects (individuals and organizations), in which each participant has equal rights to receive information, exchange opinions, and generate solutions. The theoretical basis involves substantiating the key principles on which wiki communities are formed, e.g., decentralization, openness, peering, sharing, and mass nature of activity. Wiki communities are represented by a set of specific types, such as professional, academic and research, custom, creative, public and non-commercial communities. The specific managing activities of wiki communities are described by several classification levels, such as operational activities, ensuring security, quality assurance, and motivation. The wiki community management toolkit includes a goal-setting algorithm, decision-making procedures, communications, rules of operation, typical tasks, areas of application, the operation and development cycle, and functional capabilities. It allows effective transfer of information, communication in real-time, and mutually enriching each other in forming knowledge and innovation.
