The theoretical foundations of artificial intelligence are presented: information aspects, information on binary and fuzzy logic, as well as methods and models of current areas of artificial intelligence, expert systems, knowledge engineering, neural networks and genetic algorithms. The issues of practical implementation of intelligent systems are considered in detail. There are many examples that illustrate the development and application of the methods and models in question. Particular attention is paid to economic tasks. For students, postgraduates, scientists and specialists studying and developing intelligent information systems in economic and other fields of application.
