Opis:: The paper objectives are to present the methods and tools useful in the statistical identifying the unknown parameters of the components reliability and safety of complex industrial systems and to apply them in the maritime industry. There are presented statistical methods of estimating the unknown intensities of departure from the reliability state subsets of the exponential distribution of the component lifetimes of the multistate systems operating in various operation states. The goodness-of-fit method applied to testing the hypotheses concerned with the exponential form of the multistate reliability function of the particular components of the complex technical system in variable operations conditions is suggested. An application of these tools to reliability characteristics of a ferry operating at the Baltic Sea waters is presented as well.

Opis:: The method based on the results of the joint model linking a semi-Markov modelling of the critical infrastructure operation process with a multistate approach to critical infrastructure safety and linear programming are proposed to the critical infrastructure operation and safety optimization. This method determining the optimal values of limit transient probabilities at the critical infrastructure operation states that maximize the critical infrastructure safety lifetime in the safety state subsets is proposed.

Opis:: The paper is devoted the optimization of operation process and maximization of safety lifetimes for Baltic Port and Shipping Critical Infrastructure Network (BPSCIN) at variable operation conditions related to the climateweather change. For this network, the optimal transient probabilities of BPSCIN operation process at operation states related to climate-weather change that maximize the mean value of BPSCIN safety lifetimes are found. Finally, the optimal safety and resilience indicators of considered network are presented.

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.
