The calculation of some properties for enterprise network used in plants with high exploitation risk

The modern APCS of big industrial plants including the nuclear power plants is constructed as distributed in function and facilities system. The system components are interacted between each other by means of the industrial network. The model of the APCS division and the method for calculation of worse network parameters have been developed on the base of the network calculus theory. Using this theory the maximum delay for signal propagation within a branch of APCS is computed for a given input parameters.
