Opis:: In the paper optimization of operation process and maximization of safety lifetimes for interconnected and interdependent critical infrastructure (CI) networks at variable operation conditions related to the climateweather 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 of CI network operation process at operation states related to climate-weather change that maximize the mean value of CI network safety lifetimes are found. Finally, the optimal safety and resilience indicators of CI network are presented.

Opis:: 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.

Opis:: In the paper there is presented the computer program for reliability analysis of complex technical systems with reserved and improved components along with computer program description and application. The computer program allows for automatic reliability characteristics prediction of the improved complex technical systems with hot and cold single reservation of their components and of the improved complex technical systems with reduced intensities of departure from the reliability state subsets of their components. Under the assumption that system components have exponential reliability functions, the unconditional reliability function, the mean values and standard deviations of the unconditional lifetimes in the reliability state subsets and in particular reliability states, the system risk function and the moment when the system risk exceeds a permitted level of the complex technical systems before and after their improvement are determined.

Tematy:: impact model

Opis:: 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.

Opis:: 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.

Opis:: 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.
