Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Dynamic modelling of network-centric system with topology the general tire Yu.Yu. Gromov, A.V. Yakovlev, E.O.Vasjukova The model of network-centric system with topology the general tire and any number of the connected workstations is considered. It represents the modified model described in Marchand's work. The constructed model is rather detailed and exact submission of initial specifications. However, in view of big dimension, even for rather limited number of workstations studying of properties of model is too labor-consuming. Proceeding from above stated, in this work the simplified model which is modified so will be investigated that the model of the separate workstation is a functional network of Petri. Contact positions that allows to pack a local network by combination of these positions were for this purpose added. Research of properties of the constructed network model showed that they are determined and consecutive and the network can be in process of functioning only in one of a set of states. Keywords: model of network-centric system, Petri's network, topology general tire, reachability graph, static properties, dynamic properties.
