Opis:: This paper presents the Monte Carlo simulation technique applied to the reliability evaluation of systems related to the variable operation conditions. A semi-Markov processes is applied to construct the system operation model and its main characteristics are determined. The method of linking this model with the systems reliability is proposed to get a general reliability model of the complex system operating at the variable conditions. An application of the proposed Monte Carlo simulation based on this method is illustrated in the reliability evaluation of a port grain transportation system. This way obtained results are compared with the results achieved by analytical way.

Opis:: The general model of a critical infrastructure changing its safety structure, its components safety parameters and its operation cost during the variable operation process and linear programming are applied to optimize the critical infrastructure operation process in order to get the critical infrastructure operation cost optimal value. The optimization problem allowing to find the optimal values of the transient probabilities of the critical infrastructure operation process at the particular operation states that minimize the critical infrastructure operation cost mean value in the safety states subset not worse than a critical safety state is presented. The optimization of operation cost of the critical infrastructure is proposed with considering climate-weather change process influence on the system safety.

Opis:: The paper is concerned with an application of the critical infrastructure operation process related to climate-weather change model to identification and prediction of this process for maritime ferry. There are distinguished four different processes for the corresponding ferry operating area. Further, using identified parameters of the ferry operation process and the ferry operating area climate-weather change processes, there are determined the unknown parameters of those processes. Namely, there are determined the probabilities of the processes staying at the initial states, the probabilities of the transitions between the states and the mean values of the processes' conditional sojourn times at particular states. Finally, there are predicted the main characteristics of the ferry operation process related to climate-weather change processes at the distinguished operating area.
