State of the art in maintenance modelling and simulation approaches for maintenance systems

Maintenance systems in the industry are getting much more complex, which restricts the capability of analytical modeling techniques. For complex systems, where various types of components have a distinct maintenance cost and distinct reliability importance in the system, it is more suitable to analyze the optimal maintenance policy under multi-objective criterion simultaneously. Recently, more researches on maintenance solution are developed to deal with constraints that limit various applications to be more efficient in making the decision for responsible of maintenance strategies. Many papers figure out, the unique capacity for simulation techniques in such domain of modeling, especially Monte Carlo Simulation (MCS) and Discrete Event Simulation (DES). Authors aim to be more realistic within the phenomena and complexity of components existing in industry. The power of simulation techniques was proved in solving several engineering problems. In this paper, we are focusing to make a comparison between the two big famous branches for modeling and simulation of complex maintenance systems, then we make in rise a new concept for modeling physical complex system by Bond Graph (BG).
