Opis:: The paper presents Monte Carlo simulation method applied to the reliability evaluation of a multistate system subjected to a variable multistate operation process. The system operation process model is linked with the system reliability model and proposed to get a general reliability model of the complex system operating at varying in time operation conditions and to find its reliability characteristics. The Monte Carlo simulation algorithm based on the integrated general model of a complex multistate system reliability, linking its reliability model and its operation process model and considering variable at different operation states its reliability structure and its components reliability parameters is applied to the reliability evaluation of port grain transportation system. Next the results of this simulation method application are illustrated and compared with the results obtained by the analytical method.

Opis:: Modelling and prediction of the operation and reliability of technical multistate ageing systems related to their operation processes called complex systems are briefly presented and applied to prediction of the operation processes and reliability characteristics of an exemplary complex non-homogeneous system composed of a series-parallel and a series-“m out of l” subsystems linked in series, changing its reliability structure and its components reliability parameters at variable operation conditions. Further, the linear programming is proposed to the operation and reliability optimization of complex technical systems operating at variable operation conditions. The method consists in determining the optimal values of limit transient probabilities at the system operation states that maximize the system lifetimes in the reliability state subsets. The proposed method is practically applied to the operation and reliability optimization of the considered exemplary complex system.

Opis:: The combination of the results on the reliability of complex multi-state systems related to their operation processes and the results concerning the limit reliability functions of the multistate systems is proposed, to obtain the results on the asymptotic approach to the evaluation of the large complex multi-state systems reliability at the variable operation conditions. The asymptotic approach to the large complex system reliability evaluation and the large complex system limit reliability function are defined. Limit reliability functions of selected large complex systems composed of components having Weibull reliability functions are fixed. The way of using this results is illustrated by their application to the evaluation of reliability characteristics of the large complex port grain transportation subsystem composed of three large multistate non-homogeneous series systems and changing its reliability structure and its components reliability parameters at variable operation conditions.

Opis:: W artykule przedstawiona jest metoda optymalizacji procesu eksploatacji i niezawodności złożonych systemów technicznych oraz program komputerowy pozwalający na automatyczne zastosowanie proponowanej procedury. Program wyznacza chwilowe prawdopodobieństwa przebywania systemu w poszczególnych stanach eksploatacyjnych, które maksymalizują czasy przebywania systemu w podzbiorach stanów niezawodnościowych nie gorszych niż stan krytyczny, a następnie korzystając z otrzymanych rezultatów pozwala na predykcję optymalnych charakterystyk niezawodności i ryzyka złożonych systemów technicznych. Program jest zastosowany do optymalizacji niezawodności i ryzyka lądowego linowego transportera statków. Ustalone są następujące optymalne charakterystyki: optymalna bezwarunkowa funkcja niezawodności systemu, optymalne wartości średnie bezwarunkowych czasów przebywania systemu w podzbiorach stanów niezawodnościowych, optymalna funkcja ryzyka systemu oraz optymalny moment, kiedy funkcja ryzyka przekroczy ustalony poziom.
The presented computer program for the evaluation and prediction of the complex technical system reliability and risk of optimal characteristics is based on methods and algorithms of optimisation presented in [2, 6, 7]. The computer program determines the transient probabilities in particular operation states maximising the system lifetimes in the reliability-state subset not worse than the system critical reliability state and then using the obtained results to evaluate optimal reliability and risk characteristics of the complex technical systems. In order to illustrate the application of the computer program, we determined optimal reliability and risk characteristics of a ground ship-rope transporter. Presented in the paper is the reliability and risk optimisation of a real shipyard system that can be an example of a computer aid for the operation process of transportation systems.
