Opis:
W artykule przedstawiono nowe praktyczne narzędzie do rozwiązania zagadnienia optymalizacji procesu eksploatacji i niezawodności złożonych systemów technicznych. Wykorzystano zintegrowany ogólny model niezawodności złożonych systemów technicznych w zmiennych warunkach eksploatacyjnych, łączący wielostanowe podejście do analizy niezawodności systemów z modelem semi-markowskim ich procesu eksploatacji. Ten łączny model oraz programowanie liniowe zaproponowane są jako narzędzie do optymalizacji procesów eksploatacji złożonych systemów technicznych skutkującej maksymalizacją średnich czasów przebywania systemów w podzbiorach stanów niezawodnościowych.
A convenient new tool for solving the problem of reliability and availability evaluation and optimisation of complex technical systems is presented. Linking a semi-Markov modelling of the system operation processes with a multi-state approach to system reliability analysis is proposed to construct the joint general model of the reliability of complex technical systems in variable operation conditions. This joint model and linear programming are proposed for complex technical systems for the optimisation and maximisation the system lifetimes in the reliability state subsets.

Opis:
The main aim of the paper is the adaptation of the known methods for safety modelling related to the operation process for Baltic Port and Shipping Critical Infrastructure Network. To realize this goal, the description of the four critical infrastructure networks, i.e. Baltic Port, Shipping, Ship traffic and port operation, and finally Baltic Port and Shipping are provided. The basic notations for operation process and multi-state CIN safety analysis for them are introduced. Furthermore, the Baltic Port and Shipping Critical Infrastructure Network safety function and its risk function are proposed. The practically significant critical infrastructure network safety indices like mean lifetime up to the exceeding a critical safety state, the moment when the risk function value exceeds the acceptable safety level, the component and critical infrastructure network intensities of ageing/degradation and the coefficients of operation impact on component and critical infrastructure network intensities of ageing are presented for four CIs considered in the paper.

Opis:
There is presented a practically well grounded approach concerned with the identification, evaluation, prediction and optimization of reliability, availability and safety of technical systems related to their operation processes. The main emphasis of this approach is on multi-state systems composed of ageing components and changing during the operation processes their structures and their components reliability and safety characteristics. There are proposed the convenient tools for analyzing these systems in the form of semi-markov modeling the systems’ operation processes and multistate modeling the systems’ reliability. There are described theoretical results of the proposed approach to reliability and safety analysis of multistate systems with degrading components in their operation processes and the possibility of their practical applications to the reliability and safety analysis and optimization of the complex technical port and maritime transportation systems.

Basic safety structures of multi-state systems of components with degrading safety states related to their variable operation conditions are defined. For these systems the conditional and unconditional multi-state safety functions are determined. A semi-markov process for the considered systems operation modelling is applied. Further, the paper offers an approach to the solution of a practically important problem of linking the multi-state systems safety models and the systems operation processes models. Theoretical definitions and results are illustrated by the example of their application in the safety and risk evaluation of the Stena Baltica ferry operating at the Baltic Sea. The ferry transportation system has been considered in varying in time operation conditions. The system safety structure and its components safety functions were changing in variable operation conditions.
