Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Problem of optimum distribution equally-effective negative forcing elements of network information system Y.Y. GROMOV, YU.V MININ., V.V. ALEKSEEV The work is devoted to one of the questions stability of networked information systems. In this paper we formulated and solved the problem of optimal allocation equally-effective negative external effects on the elements of a network information system. Keywords: network information system, the negative external effects, the stability of operation, probability. Contacts: E-mail: gromovtambov@yandex.ru Pp. 01-05.
