The main aim of the paper is analysis of safety of the Global Baltic Network of Critical Infrastructure Networks (GBNCIN), taking into account interactions among particular critical infrastructure networks this network consists of. The safety function and other safety characteristics: the risk function and mean values and the standard deviations of the lifetimes in the safety state subsets are determined assuming the particular critical infrastructure networks have exponential safety functions. Finally, the coefficients of cascading effect impact on the intensities of degradation of the GBNCIN, and the indicator of that network resilience to cascading effect impact, are presented.

In the paper optimization of operation process and minimization of operation cost for interconnected and interdependent critical infrastructure (CI) networks with cascading effects at variable operation conditions related to the climate-weather change are proposed. A multistate series network with assets dependent according to local load sharing (LLS) rule is analyzed and optimization of operation and safety of CI network with the LLS rule is introduced. For such CI network, the optimal transient probabilities that minimize the mean value of the total operation costs are found. Finally, cost analysis of CI network operation impacted by climate-weather change is presented in case the CI network is non-repairable and in case it is repairable after exceeding its critical safety state.

This report focuses on the safety analysis in the multistate ageing system after changing the safety state by any of its components, the inside interactions among the remaining components may cause the change of those components’ safety states. As we consider multistate systems, in a local, equal and mixed load sharing model of dependencies. For them, we analyze the safety of a multistate parallel-series and “m out of l”-series system, assuming that the lifetimes of subsystem components in the safety state subset are decreasing according to the local load sharing rule and the lifetimes of subsystems are decreasing according to the equal load sharing rule.

In the paper the safety function of a multistate series network with dependent assets, with dependent subnetworks and with dependent assets of its subnetworks is determined. The multistate series-parallel network with dependent assets of its subnetworks and multistate series-“m out of k” network with dependent assets of its subnetworks is considered. Further the multistate parallel and “m out of n” networks with dependent assets are analyzed. The safety function of multistate parallel-series and “m out of l”-series networks with dependent assets of its subnetworks, and finally of multistate parallel-series and “m out of l”-series networks with dependent subnetworks and dependent assets of these subnetworks are determined. Proposed theoretical models of dependency are applied to the safety analysis of the exemplary electricity network. Finally, the obtained results are compared with results for the considered electricity network without assumption about dependencies between assets and subnetworks.

In this paper we consider dependent Critical Infrastructures (CI) at variable operation conditions and present multistate approach to their safety analysis. The safety of dependent Critical Infrastructures at variable operation conditions is described. The local, equal and mixed load sharing models of dependency subjected to the operation process are introduced. The conditional safety functions at the particular operation states and the unconditional safety functions of a multistate series network with dependent assets, with dependent subnetworks and with dependent assets of its subnetworks according to LLS, ELS and MLS rules are determined. Furthermore, the all models of dependency are applied to safety analysis of a multistate parallel and “m out of n” network with dependent assets, parallel-series and “m out of l”-series network with dependent assets of their subnetworks at variable operation conditions.

In the paper a multistate approach to reliability analysis of series systems with dependent components according to the local load sharing rule is proposed. As a particular case, the reliability function of a multistate series system composed of dependent components having exponential reliability functions is determined. The mean values and standard deviations of the multistate system lifetimes in the reliability state subsets and the mean values of its lifetimes in the particular reliability states are determined. Application of the proposed model of components’ dependency to the reliability analysis of the exemplary system is presented.
