Chemical Technology, Control and Management
In order to optimize the delay time of information flows in the nodes, multiservice networks propose the application of the theory of fuzzy sets, with the help of which models are developed for calculating the delay time, taking into account the inaccuracy of time, simple, correct operation and aging of information. A fuzzy model for calculating the average message delay time through communication nodes in multiservice networks is given, with each channel of switching nodes being modeled as a queuing network. A single-criterion problem of the optimal distribution of information flows over the channels of switching nodes with ill-defined data …
