Opis:: In the paper, definitions and theoretical results on system operations process, multi-state system reliability, risk and availability modelling are illustrated by the example of their application to a bulk cargo transportation system operating in Gdynia Port Bulk Cargo Terminal. The bulk cargo transportation system is considered in varying in time operation conditions. The system reliability structure and its components reliability functions are changing in variable operation conditions. The system reliability structures are fixed with a high accuracy. Whereas, the input reliability characteristics of the bulk cargo transportation system components and the system operation process characteristics are not sufficiently exact because of the lack of statistical data. Anyway, the obtained evaluation may be a very useful example in simple and quick systems reliability characteristics evaluation, especially during the design and improving the transportation systems operating in ports.

Opis:: Przedstawiono połączenie wyników dotyczących niezawodności systemów z uwzględnieniem ich procesów eksploatacji i wyników dotyczących granicznych funkcji niezawodności systemów równoległo-szeregowych. Zastosowanie asymptotycznego podejścia do oceny niezawodności i gotowości wielostanowego systemu równoległo-szeregowego w zmiennych warunkach eksploatacyjnych zostało zaprezentowane na przykładzie stoczniowego systemu transportu linowego.

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.

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:: The paper contains an analysis of the operational process of heat supply system with taking into consideration its reliability. The specific character of the operation of heat-supply systems has been considered in this work. In the process of the exploitation of heat-supply systems there have been distinguished five operational states, assuming as a criterion of the level of indoor temperature decrease in residential rooms. The method of modelling the operational reliability of heat-supply systems is worked out. The methodology of determining the overall index of heat-supply system reliability has been presented. The measure of heat-supply system reliability has been assumed as the scale/quantity of inadequate supply of heat power at a given state. Calculations have been carried out regarding the changeability of exterior conditions for one of the groups of customers – residential users. On the basis of the operational data for the heat supply system with two heat sources shortage quantities of heat power and the probability of their occurrence have been calculated as an application of this methodology.

Opis:: In the paper an approach to the reliability analysis of multi-state systems with dependent components operating at variable operation conditions is presented. The multi-state reliability function of complex system is defined and determined for the shipyard rope ship elevator. In developed models, it is assumed that system components have the multi-state exponential reliability functions with interdependent departures rates from the subsets of reliability states.

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.
