Résumé en anglais

We present a numerical method for the optimal design and maintenance for the heated hold-up tank system. A multi-objective problem is framed to consider simultaneously the objectives of maximizing the operation profit and maximizing the reliability. The system consists of a tank containing a fluid whose level is controlled by three components: two inlet pumps and one outlet valve. A thermal power source heats up the fluid. The failure rates of the components depend on the temperature, the position of the three components monitors the liquid level in the tank and the liquid level determines the temperature. We model the system by a piecewise deterministic Markov process (PDMP). To find the solution of the optimal maintenance interval, the non-dominated sorting genetic algorithm-II (NSGA-II) is used< Réduire
