Industrial Automatic Control Systems and Controllers Annotation << Back Practical Development of Specialized Documentary Communication E.N. Matyukhina, V.M. Sobol, I.V. Udartsev The organization of the subject area of the subscription documentary exchange service, its structure and conceptual device, as well as formal design techniques, methods of program verification and research of the automated system are considered. There has been widespread use in the implementation of a specialized automated documentary exchange system. It is stated that it is necessary to create the prerequisites for industrial production of programs by using different forms of their specification and formalization. Practical considerations are given to ensure that the methodology of transferring the basic functions of the automated system to the new hardware and software platform is provided using industrial programming technology, which preserves the compatibility of the software with a large fleet of subscriptions in its daily operation due to standard rules and unifies.
