Texto completo da fonteGlobally, the development of wind farms is experiencing exceptional growth, visible through the increase of wind power installed annually and global wind power production. 2020 was the best year in the history of the global wind industry and it is estimated that wind turbine installation should grow three times faster over the next decade. Any energy production system is subject to random breakdowns which trouble production plans. Aging, breakdowns and maintenance times are examples of random phenomena often observed in those systems. In the particular case of wind turbines, the highly volatile and uncertain nature of the wind means that the duration of maintenance actions must be minimized in order to maximize the availability of the wind turbine and therefore its energy production. In addition to this, the risks associated with maintenance make it the major cause of accidents in the wind energy sector. Considering the lack of training for maintenance technicians and the absence of a prevention plan, a maintenance plan optimizing the number of interventions and their duration and considerably reducing the technical, economic and human consequences linked to these operations is essential. Maintenance and production are two main functions for any type of production. In practice, these two functions are often managed separately despite being in reality so close. Indeed, integration policies can improve productivity and reduce costs considerably. In this context, the research work proposed in this thesis consists in determining new maintenance policies integrated into energy production for a wind farm. Two integrated maintenance strategies were tested: perfect then combined imperfect / selective coupled to energy production, satisfying a service rate while taking into account environmental and operational constraints and. Indeed, for each strategy developed, the goal is to simultaneously determine an economical energy production plan and an optimal maintenance plan minimizing a total cost of energy production and maintenance. The particularity of this study is to consider the impact of the variation in energy production on the degradation of the wind turbine. The problem was modeled by the development and optimization of analytical models, then validated by numerical examples and sensitivity studies proving the robustness of the analytical models developed

Texto completo da fonteThe 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

Texto completo da fonteCurrently, 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

Texto completo da fonteIn this study, we are interested in a machining production system which is one of the manufacturing processes most adopted by the various mechanical industries (automotive, aviation…etc.). The objective of this multidisciplinary thesis (Mechanics and Industrial Engineering) is double: (1) the development of a new thermomechanical model of oblique cutting in dry machining and (2) the maximization of profit in order to establish a strategy production and a preventive maintenance plan.The coupling between the machining operation and the part "simultaneous optimization of production and maintenance costs" is done by considering the effect of cutting conditions on the generated surface quality and on the tool wear. In the proposed approach, wear is taken into account through Taylor's empirical law and the machined surface quality is predicted via a new model of vibrations in oblique cutting.The first objective of this work concerns the development of a new thermomechanical model of the oblique cutting with vibration. In this analytical cutting model, the vibratory system is assimilated to a system with a single degree of freedom in the tool feed direction. We take into account the coupling between tool oscillations, the thermomechanical process of chip formation as well as the regenerative effect. The latter results from the variation in the material quantity to be machined between two successive passes. The coupling between all of these mechanisms makes the problem to be solved strongly nonlinear. A resolution algorithm making it possible to reduce the computation time has been implemented.The second objective of the thesis is achieved through the development of an analytical model where the optimization consists in maximizing a profit integrating selling price of finished product, production and maintenance costs. We note the originality of this part consists in considering the impact of the machining conditions, especially the cutting speed, on the production durations and costs, the quality of the machined parts as well as the degradation of the production system. The impact of machining conditions on three fundamental aspects is therefore considered simultaneously for the "simultaneous optimization of production and maintenance costs" part. The first concerns the impact of machining conditions on production time and costs. The second concerns the impact on the degradation of the machining system and therefore on the optimal maintenance plan to be adopted. The third concerns the impact on the quality of the output product which directly affects the selling costs and more specifically the total profit. These interactions are taken into account through the development of an analytical model to establish an optimal integrated production maintenance plan for the machining system, illustrated by the optimal switching date for changing cutting speed and the optimal numbers of batches to produce before every preventive maintenance action for every production phase. Every production phase is characterized by a cutting speed

Texto completo da fonteIn 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
