Modelling and Optimization Techniques for Maintenance Systems Using Simulation: a Systematic Literature Review

The impact of maintenance strategies is a critical key performance factor in industry. Simulation concept has become the primary technique used for optimizing models of maintenance strategies. This paper aims to report the state of the art of the techniques provided to model and to optimize maintenance systems. The authors offer a summary of classified papers published in the field. The need of simulation approach is highly recommended by authors given the complexity found in real industrial cases. Few papers have been reviewed based on a specific maintenance strategy and the most retain minimizing cost as a single optimization function, in a finite horizon planning. Discrete Event Simulation (DES) has been the most figured simulation approach and has been coupled sometimes with other techniques. Moreover, this paper highlights various tools used in modelling and simulation in order to optimize maintenance strategies. Real cases have been figured out while academical ones are highly reported in the literature. The findings emphasize on investigating the gaps between theory and real systems to assist in building a generic approach in order to overcome the reported limitation.
