Modelling Safety of Baltic Port and Shipping Critical Infrastructure Network

In the paper, the three critical infrastructure networks are introduced, i.e. port, shipping, and ship traffic and port operation information. For every of them the main safety paremeters are defined. Furthermore, the multistate system component and the multistate system main safety characteristics, i.e. their mean values of the lifetimes and in the safety state subsets and in the particular safety states and standard deviations and the moment when the system risk function exceeds a fixed permitted level are determined. Finally, the Baltic Port and Shipping Critical Infrastructure Network is defined and described in the same way
