Tematy:: reliability analysis

Opis:: The paper presents analytical and Monte Carlo simulation methods applied to the reliability evaluation of a system operating at two different operation states. A semi-Markov process is applied to construct the system operation model and its main characteristics are determined. Analytical linking of this operation model with the system reliability model is proposed to get a general reliability model of the system operating at two varying operation conditions and to find its reliability characteristics. The application of Monte Carlo simulation based on this general model to the reliability evaluation of this system is proposed as well. The results obtained from those two considered methods are evaluated.

Tytuł:: Monte Carlo simulation of climate-weather change process at maritime ferry operating area
Autorzy:: Kuligowska, E.
Powiązania:: https://bibliotekanauki.pl/articles/298021.pdf
Data publikacji:: 2018
Wydawca:: Uniwersytet Warmińsko-Mazurski w Olsztynie
Tematy:: Monte Carlo simulation
climate-weather change process
critical infrastructure operating area
Opis:: The paper presents a computer simulation technique applied to generating the climate-weather change process at Baltic Sea restricted waters and its characteristics evaluation. The Monte Carlo method is used under the assumption of semi-Markov model of this process. A procedure and an algorithm of climate-weather change process’ realizations generating and its characteristics evaluation are proposed to be applied in C# program preparation. Using this program, the climate-weather change process’ characteristics are predicted for the maritime ferry operating area. Namely, the mean values and standard deviations of the unconditional sojourn times, the limit values of transient probabilities and the mean values of total sojourn times for the fixed time at the climate-weather states are determined.

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

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

Tematy:: operation process

Monte Carlo simulation
Opis:: This paper presents the computer simulation technique related to the reliability of an object under variable operation conditions. The considered object operation process is modelled using semi-Markov processes and its reliability is analysed by application of the conditional reliability functions in its different operation states. The backgrounds and procedures of the Monte Carlo simulation method application to an object at variable condition reliability analysis are proposed and applied to reliability evaluation of an exemplary object. Consequently, under arbitrarily assumed the parameters of this exemplary object operation process and its conditional reliability functions, using the proposed Monte Carlo simulation procedures, the transient probabilities of the exemplary object operation process at the particular operation states and its unconditional reliability function are determined. Further, the linear programming is introduced and proposed to reliability optimization of an object at variable operation conditions and the optimal transient probabilities of the exemplary object operation process at the particular operation states and its optimal unconditional reliability function are determined. Finally, some practical suggestions on the modification of the exemplary object operation process improving its reliability are proposed.

The complex technical system with the reliability structure and components’ reliability parameters changing at the various operation states is defined. The selected system operation process parameters and the hypothetical distribution functions of the conditional sojourn times at the operation states are defined and identified. The reliability functions of the multistate system and components are introduced and their parameters are identified. The Monte Carlo simulation method is proposed to the complex system reliability evaluation.

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.
