Simulation Approach for Optimal Maintenance Intervals Estimation of Electronic Devices

Simulation is a powerful and flexible technique for imitation of variety of stochastic processes and it has attractive advantages in comparison to analytical routine solutions. In this paper, the Monte Carlo simulation technique is used for imitation of operational process of electronic devices which is formalized by the model of Semi Markov process. The model considers sudden, gradual, latent and fictitious failures, human factor of service staff and time parameters of preventive maintenance. Simulation approach permits to obtain necessary data for estimation of recommended value of maintenance interval according to suggested optimality criterion. Moreover, it could be easily used for investigation and analyzing of the process with different combinations of input parameters.
