Optimisation des stratégies de maintenance verte pour les systèmes de production

Abstract : In this thesis, condition-based maintenance strategies are proposed for production systems of goods and services. These strategies are developed while taking into account the environmental degradation caused by the deterioration of the production system. The system is subjected to random deterioration which impacts the environmental quality. The proposed maintenance models aim to assess the system deterioration in such a way to reduce the environmental degradation. To control this deterioration, inspections are performed on specific dates. The objective is to determine optimal inspection dates which optimize a given performance criterion. Two mathematical optimization models are then proposed in this thesis. The first model considers the average total cost per time unit, while the second model considers the stationary availability of the system. The constrained optimization has also been discussed in this work where the objective is to minimize the average total cost per time unit under an availability constraint or to maximize the stationary availability of the system under a budget constraint. On the basis of Nelder-Mead method, inspection dates as optimal solutions are computed for each optimization criterion. Numerical examples are provided to show the applicability of the proposed condition-based maintenance strategies
