Contribution au développement de politiques de maintenance intégrée pour un système à multi-produits

Abstract : Currently, the competition between companies is reflected in the revision of the current industry strategies to improve the planning of production and maintenance. In fact, the non- satisfaction of the customer on time is often due to a random demand or a sudden failure of production system. Therefore, it is necessary to develop new maintenance and production strategies. In this memory, we treat some maintenance policies integrated with production for a manufacturing system. This paper deals with the problem of maintenance strategy and production planning for a multiple-product manufacturing system. The manufacturing system under consideration consists of one machine which produces several products in order to satisfy random demands corresponding to every product. The significance of the present study is that the study deals with the case of a system which produces several products. In this study we have developed and optimized analytically production policies for a multiple-product manufacturing system, in order to meet several random requests characterizing respectively different customers. These policies consist of establishing periodic production plans for each product, minimizing the costs of production and storage while meeting predefined service level for each product. Subsequently, we have developed optimal strategies of maintenance, taking into account the influence of economic production plans obtained, on the evolution of the degradation of the production system. Several scenarios have been studied according to the durations of the sub-periods of production and the cost of set-up of each product. In the end, case studies were treated in order to compare the developed analytical results
