Annotation: Balance models of management and planning of processes of production of final products at enterprises are considered. Diagrams of the assembly of products based on the input -output method of Vasily Leontiev are given. According to the diagrams, according to the Gozint theorem, matrices of direct and complete needs are formed, according to which, according to the proposed algorithm, the required parts and assemblies are evaluated for the production of various products as a final product. A method of encryption and decryption is proposed for the transmission of messages in digital format containing calculated data and technological schemes that are confidential. Examples of performing digital operations are given.
Keywords: balance model, Gozint diagram, matrices of direct and full needs, plan, algorithm, confidential message, encryption, message extraction.
