Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back A dynamic model of network-centric information system Yu.Yu. Gromov, A.V.Yakovlev, E.O.Vasjukova In the article the questions of modeling based on Petri nets network-centric information systems implemented in the architecture “clientserver”. Received the underlying structure is a model of informational interaction and has a strict mathematical description, which allows to analyze the interaction between three subjects of information relations: user with client and client with server. Research of dynamic models of network-centric systems allow to identify the main static and dynamic properties, based on which we can draw conclusions about the functioning of the system. Keywords: Network-centric information system, Petri net, reachability graph, the architecture “client server”. Contacts: E-mail: gromovtambov@yandex.ru Pp. 17-21.
