Contribution au développement des stratégies de gestion de maintenance intégrée faisant appel à la sous-traitance

Abstract : The general study framework is built around the maintenance management integrated with the production, taking into account the constraint of subcontracting. Our research specifically addresses the economic management of the production delivery from one or more subcontractors that differ in their availability and cost per unit of production. The economic study consists in minimizing the total cost including production, inventory and maintenance. Our study will be conducted along two axes. In a first axis, we consider a constant demand on an infinite time horizon. An analytical study is conducted to determine the maintenance policy to be adopted and the choice between several subcontractors. In a second axis, we considered a random request to accommodate over a finite time. This application must be met in a required level of service by using outsourcing while assuming that the failure rate of the main machine varies with use and time. The objective was to propose an optimal production maintenance plan that satisfies the level of service and taking into account the deterioration of the machine while minimizing production, inventory and maintenance costs. The analytical models developed in the two axes are validated by numerical examples and interpreted through sensitivity studies
