Industrial Automatic Control Systems and Controllers Annotation << Back Dominant Aspects of the Methodology for the Development, Verification and Research of an Automated Document Exchange System S.Yu. Balandin, V.B. Korotaev, E.I. Mitrushkin, V.M. Sobol The complex tasks of the methodology for the creation, control and modernization of telecommunication devices of a specialized system for the exchange of documentary information based on a data transmission transport network are considered. A system for addressing documentary messages is proposed, which is one of the bases of information interaction in spatially distributed complexes. The functional structure and software implementation of the tasks of the specialized subscriber service of the automated system of documentary exchange are considered. A simulation complex for monitoring the correctness of the implementation of the subscriber protocol of documentary exchange, used to conduct various types of tests of a specialized telecommunications system, is envisaged; a methodology of automated testing is proposed. The necessity and postulation of the paradigm of preserving the algorithmic continuity when updating the terminal park of subscribers is stated. Keywords: subscriber service, telecommunication complex, system addressing, infosphere, structuring of programs, data exchange system, documentary exchange, testing, testing of complexes, product support.
