Reliability of complex system under operation process influence : Monte Carlo simulation Approach

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.
