Повний текст джерелаBuilding an exemplary green reputation has become essential for industries in all sectors. To this end, and with the aim of reducing production waste, resource consumption, and greenhouse gas emissions, manufacturers are turning to the adoption of the circular economy concept. Among the processes used in this context, we find remanufacturing, which extends the life cycle and use of products in three main steps: recovery and collection of used products, remanufacturing operations, and redistribution of remanufactured products.In this thesis, we are interested in an application of the remanufacturing process as a preventive measure. We consider products in use by customers, over a finite horizon, and we proceed to the recovery of these products at predetermined times to refurbish them or improve their working condition, and then to redistribute them for further use. The overall objective is to develop economically and environmentally efficient remanufacturing strategies, integrating the different phases of remanufacturing and considering the characteristics of the product and the conditions of its use.First, we consider two major decisions in the remanufacturing activity. The first one is related to the stock capacity and consists in selecting the products to be recovered and their number. Since each product is characterized by a grade, we are interested in the second decision to determine the level of remanufacturing and the grade to be reached for each recovered product.Second, by extension of the first problem, we integrate the characteristics of the products and the profiles of the customers. We focus on the structure of the product composed of several functionalities and characterized by a performance determining its grade and depending on the quality of execution of the functionalities. We also consider the profile of the product user, based on the frequency of usage impacting the realization of the product functionalities and grade. Thus, a high frequency of usage gives a lower execution quality of the features. We develop the mathematical model to make the link between the performance of a product and the quality of execution of its features. We propose at this stage the multi-objective optimization of the recovery stage independently of the other remanufacturing action decisions.Finally, we consider that a product is made of several components, each of which intervenes in a specific way in the execution of the functionalities offered by the product. Moreover, each component is characterized by a given performance. In this case, the customer profile, i.e., the frequency of use, impacts the performance of each component and thus the overall performance of the product. We develop the mathematical model that allows calculating the performance of a product according to the performance of its components and their relationship with its functionalities. In addition to decisions on product selection and remanufacturing levels, we integrate the optimization of the transportation and recovery stage of used products.For each problem studied, a multi-objective mathematical model is developed, solved using metaheuristics and/or heuristics. In addition, multi-criteria decision analysis is performed to help the decision-maker to determine the best remanufacturing alternatives to implement. Several numerical experiments have been performed to illustrate the applicability of the different approaches proposed

Повний текст джерелаClosed-loop supply chain (CLSC), as an important branch of supply chain, has received increasing attention in recent decades. However, CLSC for perishable food products that is more complex than classic CLSC has been seldom studied in spite of its growing applications in practice. This thesis aims to develop new models and methods for optimizing closed-loop food supply chain with returnable transport items. To this end, three new problems are investigated.Firstly, a closed-loop food supply chain with returnable transport items (CLFSC-RTI) is studied. This problem involves a single manufacturer and a single retailer. Outsourcing is permitted and RTI purchasing budget is limited. The objective is to maximize the total profit of the supply chain. The problem is formulated as a mixed integer linear program (MILP) and it is proved to be NP hard. To solve the problem, an improved kernel search-based heuristic is designed. Computational experiments on a real case study and extensive random instances demonstrate the effectiveness and efficiency of the proposed model and heuristic.Secondly, a bi-objective closed-loop food supply chain with returnable transport items (BCLFSC-RTI) is investigated. The two objectives are to maximize the total profit and to minimize carbon emissions, simultaneously. The studied problem considers multiple retailers. For this complex bi objective problem, a bi-objective MILP is proposed for its modelling, and an iterative ε-constraint method is applied to solve it. Then, a relax-and-fix heuristic is developed to solve the transformed single objective problem in each iteration of the ε-constraint method. Computational results based on various randomly generated instances show that the performance of the proposed method is comparable to that of a state-of-the-art commercial optimization solver CPLEX.Finally, a closed-loop food inventory-routing problem with RTIs (CLFIRP-RTI) is addressed. In this problem, a vehicle routing problem is integrated and returnable transport items with different protective levels are considered. An appropriate MILP is proposed to formulate the problem, and the problem is proved to be NP-hard. Numerical experiments are carried out to validate the proposed model

Повний текст джерелаReverse logistics network design is a crucial issue in which it is important to take into account the selection of the most appropriate partner with sustainability concerns. This partner can be a supplier or a third-party reverse logistics provider (3PRLP). However, research works that consider reverse logistics (RL) network design, partner selection, and sustainability issues simultaneously are rather limited till now. This research work proposes an integrated sustainable approach for partner selection and closed-loop supply chain (CLSC) network configuration, particularly in the case of outsourcing reverse logistics process to third-party provider. We propose a trade-off between sustainability criteria for both supplier and 3PRL provider selection. A multi-objective mixed-integer programming (MILP) model is also proposed to configure CLSC network and to select the best partners. The model minimizes the total cost of sourcing, and the total greenhouse gas emissions, while it maximizes the total value of reverse logistics, and the number of new job opportunities. A numerical example is also presented to illustrate the proposed approach

Повний текст джерелаSupply chains are ubiquitous across industries and a considerable effort has been invested in supply chain management techniques over the last decades. In Telecommunications service industries, it often involves repair operations and consequently takes place in a closed-loop supply chain. In this context, supply chain management is concerned with optimally planning movements of faulty parts and spare parts based on a demand forecast and in the face of conflicting objectifs (stock out, storage, repair, transfer). This thesis describes this optimisation problem and based on a case study. Specifically, we consider a tactical planning decision support system. This system depends on a generic modeling of the problem that can be applied on a wide range of supply chains. We present an exact method and a metaheuristic to solve this problem and evaluate our approaches against a variety of instances of different sizes. We also study the ability to emulate specific management policies (e.g., just-in-time replenishment, minimal repair) by weighting the objectives. Finally, we investigate how to apply successive plans generated by the system and study the capability to face forecast uncertainties

Повний текст джерелаMotivated by the change of regulations in the matter of sustainability, but also by pure economic constraints, several industries have found themselves obligated to develop new methods and models for the management of products that are at the end of their life cycle. In this context, the remanufacturing aims at managing the recovery of the product’s value before its end of life. This type of action will extend the product life cycle and save the use of the raw material. These remanufactured products will be re-injected in a market that serves another class of customers, different from the one using new products. In other cases, the remanufactured products are reused as spare parts for the maintenance, but this reuse may vary according to the maintenance strategy adopted. This thesis focuses on the integration of a hybrid flow supply of spare parts in a service model based on stochastic degradation of a production system. Two types of spare parts supply flows are studied: a direct flow and reverse flow. The direct flow is represented by the use of new spare parts and the reverse flow is represented by the reuse of the recovered parts during the replacements, with the ability to perform remanufacturing action to improve the degradation level of these spare parts. Several issues were treated to better understand the impact of remanufacturing policies over the performance of a production system. At the beginning we started our study with production systems composed of a single machine. In this context, we proposed sequential studies then integrated one to optimize the maintenance policy as well as the Hybrid provisioning in regard to spare parts destined to replacement actions. Similarly, we’ve studied the production management subjected to quality constraint based on the machine’s degradation process. Furthermore, we’ve presented generalizations of studied models within the context of a production system composed of several machines. Finally, we’ve developed an aid-to-decision-design tool for production systems within the remanufacturing process. This problematic aims at –from a strategic point- selecting the best group of machines to build a new system of production that is able to satisfy the constraints of a production defined by the decision maker

Повний текст джерелаIn a traditional supply chain, production, inventory and distribution operations are treated separately due to the complexity of jointly planning these operations and the lack of information shared among stakeholders. Today, in order to face the fierce competition in the global market, companies are forced to jointly plan these activities in order to benefit from the economic and environmental benefits generated by this integration. Among the optimization problems existing in the literature, the integrated planning problem which jointly optimizes production, inventory management, distribution and vehicle routes decisions, has recently received considerable attention, despite its NP-hardiness. Indeed, its benefits in terms of synchronization between processes, cost reduction and improved service level can be significant. In addition, the optimization of this problem in the context of closed-loop supply chains with End-of-Life Product (EOL) management leads to the development of increasingly sustainable supply chains. Furthermore, growing concerns about environmental issues linked to industrial activities have led to the emergence of policies to control carbon emissions. Taking these regulations into account can have a positive impact on the company's environmental responsibility. To meet these challenges, the objective of this thesis is to design models and develop optimization approaches to solve an integrated planning problem of production, remanufacturing, storage and direct-reverse distribution operations. We considered a closed-loop supply chain consisting of a production line for new products, a remanufacturing line for returned EOL products, two types of inventories for reusable products and EOL ones to be remanufactured, as well as customers with dynamic demands for delivery and pickups. The goal is to determine the optimal amounts to produce, remanufacture and store, as well as the order of visiting customers in order to meet their requests simultaneously for delivery and pickup, while minimizing the total cost due to the involved operations. First, a linear integer model is proposed to optimize the supply chain system by considering one or more vehicles with limited capacity. The second part of the thesis concerns the development of a two-phase decomposition heuristic to solve the extended integrated model. The last part of the thesis is devoted to the integration of carbon dioxide emissions into production, remanufacturing, inventory and distribution decisions and to study the behavior of carbon emission levels in the context of cap-and-trade policy. Numerical experiments make it possible to demonstrate the applicability and the limits of our approaches
