Blouin, Alexandre. "Planification en logistique du transport : de la pratique à la théorie." Compiègne, 2007. http://www.theses.fr/2007COMP1706.
Within the context of a CIFRE contract, four real life problems encountered by the company OPTILOGISTIC are studied in this Thesis. OPTILOGISTIC produce software packages for transportation, from the optimisation of vehicle routing to the vehicle navigation. We perform original and effective methods like an adaptation of A * Algorithm in order to manage trailer in vehicle routing problem. Likewise, two kinds of inventory routing problem are analysed. Heuristics are suggested to solve the first one which concerns replenishment of a plant from several suppliers. For the second one, we couple the choice of inventory replenishments politic with routing construction in order to satisfy customers' demands minimizing routing cost. Finally, we study a driver scheduling problem for which we develop two exact methods based on cut generation

The proposed joint delivery problem (JDP) is a delivery tour planning problem on a time horizon decomposed into elementary periods or rounds, the time horizon being the common delivery period for all products. The data of these parameters provides a linear formulation of the problem, with binary decision variables. The model also incorporates the constraints of meeting demand from stock and the quantities supplied, storage and transport capacity constraints.In order to also solve the problem of choice of delivery rounds, it is necessary to introduce in the model several constraints and variables related to the sites visited during each round. It is proposed to solve the problem in two steps. The first step is the calculation of the minimum off-line cost of the tour associated with each subset of sites. One can observe that for any given subset of sites, the optimal Hamiltonian cycle linking those sites to the warehouse can be calculated in advance by a traveling salesman problem algorithm (TSP). The goal here is not to fully analyze the TSP, but rather to integrate its solution in the formulation of the JRP. In the second stage, binary variables are associated with each subset and each period to determine the selected subset of sites in each period and its associated fixed cost

The works presented in this thesis are related to new techniques of optimization for the solution of four important problems of two fields : transport logistics, computer vision and image processing. They are nonconvex optimization problems of very large dimensions for which the research of good solution methods is always of actuality. Our work is based mainly on the DC programming and DCA that have been successfully applied in various fields of applied sciences, including machine learning. It is motivated and justified by the robustness and the good performance of DC programming and DCA in comparison with the existing methods. The thesis is divided into five chapters. The first chapter, which serves as a reference for other chapters, presents some tools from the bases of DC programming and DCA. The second chapter discusses the problem of supply chain design at the strategic level, which can be formulated as a mixed integer linear program. We treat this problem by DC algorithms via exact penalty on the basis of suitable DC decompositions and a technique for finding a good starting point. The third chapter is concerned with the discrete tomography applied to the problem of binary image reconstruction. This problem is solved by three different approaches based on DCA. In the fourth chapter, we study the problem of image segmentation using Fuzzy C-Means clustering via DCA. A nonlinear estimate of the fundamental matrix in computer vision by the trust-region method based on the truncated conjugate gradient method or DCA is developed in the final chapter

The objective of the first part consists in studying the modes of transport from the origin until nowadays. We list the most striking periods and analyze the correlation between historic periods of great benefit for Spain and its system of transport. This part presents the milestones which have contributed to shape the face of Spain in the XXIst century in terms of infrastructures of transport. The analysis of the various plans shows the efforts of the State to favour the territorial cohesion within the country but also the limits and drift which have resulted from these plans. The second part describes the factors of change of the recent policy from 2012 and analyzes its effects on a possible strengthening of Spain concerning its international exchanges. The reflexion continues in order to identify assets and perspectives that the country offers to foreign groups on logistics aspects. Thanks to two case studies, we explain how certain large European operators of the sector gamble on contributing to make of Spain a strategic platform of the South for international exchanges. To carry out these ambitious projects, these operators bought important companies in the Spanish market. The aim consists in understanding their key factors of success and their possible weaknesses. To increase their performances at a local and international level, these groups need trained staffs. The third part proposes a state-of-the-art of trainings offered in Spain for the sector of transport and logistics and reveals a deficit in this field. To accompany these companies in their process of internationalization, we suggest a contribution to a training plan, based on sandwich courses
Abdi, Ibrahim Fathiya. "La logistique urbaine." Thesis, Paris 2, 2019. http://www.theses.fr/2019PA020021.
Urban logistics deals with how to transport goods by optimizing the various flows that circulate within the center of a city. This integrates into its functionality several environmental, economic, urbanization issues. However, commercial activities can not be carried out without the urban transport activity.On the one hand, the main objective of this study is to research the existing determinants of urban logistics in developed countries to improve the design of urban logistics at DJIBOUTI, concerning the organizational concepts of goods transport activities in cities, urban infrastructures , the regulations put in place in the context of urban logistics.On the other hand it is a question of putting in place an urban logistics specific to DJIBOUTI.Today the challenges in the Republic of Djibouti are:- Undertaking to make the logistics in the city more competitive and related to the environment;- Associate in a planning plan the movements of the goods.Thus the utility of our research is to organize the transport of goods in the city, to design an urban logistics that meets the needs of tomorrow. Freight issues are a major challenge for public authorities in charge of managing the mobility, accessibility and sustainability of cities and the entire territory. This is essential for Djibouti to develop its urban trade that is realized within the city by having the largest container terminal in East Africa. On the other hand, the urban logistics sector is still in an embryonic state

Logistics is a key function in economic development, for production and for distribution, it gives birth to an emerging new industry. Logistics is also a key factor of spatial functioning and organization, requiring an adequate attention and priority in planning. A comparison of Chinese and French experiences dealing with "freight villages" throws light on the major stakes and questions of introducing logistics into urban and regional planning agenda. This thesis tries to take stock of experiences of ways to take into account logistics and his characteristics in urban and regional planning

Ramdane-Cherif, Wahiba. "Problèmes d'optimisation en tournées sur arcs." Troyes, 2002. http://www.theses.fr/2002TROY0006.
This thesis deals with vehicle routing problems in which a subset of arcs must be treated in a network. Such problems are relatively neglected compared to node routing problems, despite important applications like waste collection, snow plowing or inspection of power lines. The CARP (Capacitated Arc Routing Problem) is the main academic problem of that kind, but it is not sophisticated enough to handle real-life applications. The thesis investigates three new problems generalizing the CARP: the ECARP (Extended CARP), that copes with very realistic networks with one-way and two-way streets, prohibited turns, multiple dumping sites, etc. ; the SCARP (Stochastic CARP), whose the aim is to compute robust solutions, keeping their quality in case of imprecise data ; the PCARP (Periodic CARP), a long-term planning problem in which treatment days must be assigned to each street, subject to given frequencies, before computing the trips for each day, in order to minimize a total cost over the horizon considered. These problems are modelled and then solved thanks to new algorithms that are appraised on classical and new benchmark instances. A hybrid genetic algorithm is proposed for the first time for the CARP. It outperforms all published methods and allows one to solve to optimality several open instances from literature. This algorithm is extended in a non-trivial way to handle the ECARP, the SCARP and the PCARP. Our research also describes fast heuristics for large scale instances and a cutting plane algorithm for the ECARP. This work illustrates the power and flexibility of genetic algorithms and reduces in a significant way the gap existing between academic vehicle routing problems and industrial applications

Globalization has promoted explosion of international trade and great importance of maritime transportation system which can’t be overlooked in global supply chain continuity. Containers are remarkably useful and efficient, but potential security risk sources in ports and their possible use for terrorist attacks has drawn great attention since 09/11 events. In addition to measures in place, European Union has set up specific initiatives to enhance international transportation security while improving global trade, hence increasing ports competitiveness. To contribute to this securization and fluidification trend, we have participate in this doctoral research to the elaboration of a new security risk management approach for the international goods transportation system. This has enabled us to think about the transposition of traditional risk management methods in a supply chain context. We have transferred HACCP method from food industry to the container transportation chain. Results of the case study realized on Le Havre Port show that this transposition may imply adaptations according to the risk and the context, and point out HACCP limits when qualitative data are used. In perspective, we propose to examine these limits in more details and explore HACCP combination with other risk management tools in order extent its application to international transportation

This thesis focuses on the transportation problem of a local carrier TCP-Distribution. The study is on the node routing problem (VRP) and specifically to cases with Heterogeneous fleet (H), with Mixed Backhauls (MB), and Time Windows (TW), the problem is called HVRPMBTW. It is few studied in literature. After a general introduction to the transportation problems, and a complete description of the problem studied, we suggest several resolution approaches. A mathematical model is developed; it is a linear model with real and binary variables (mixed LP) which is used by an exact method. The first metaheuristic approach is proposed, it is based on an Ant Colony Optimization (ACO) combined with an efficient local search. This method has shown its effectiveness on HVRPMBTW. A second approach is developed, called a Particle Swarm Optimization (PSO) combined with the effective local search. The new results obtained improve the previous results. The last part of this thesis is dedicated to an industrial application. The methods developed are applied to the industrial cases. A Performance Management Tool is implemented and used with a graphic box developed. Its aim is to calculate and analyze the indicators, and to use the optimization methods
Jia, Zhenzhen. "Planification décentralisée des activités de production et de transport : coordination par négociation." Thesis, Bordeaux 1, 2012. http://www.theses.fr/2012BOR14734/document.
The present work aims to study the coordination problems in the context of decentralized planning, based on the postulate that centralized management is not suitable regarding the confidentiality objectives of each partner of the same supply chain. More specifically, the aim of this work is to develop a negotiation protocol seeking to reach a “win-win” planning solution, i.e. the development of plans satisfying the producer (the customer of transportation service) while increasing profit of transport operators. The development methodology of this work contains two phases. The context of decentralized planning of activities of one producer and one transport operator is firstly studied. The main objective is to characterize the linear programming models and the key determinants to develop the coordination protocol and also to implement the simulation of both partners in order to identify the factors affecting the overall performance. The conducted experimentation in this context is based on the concept of the design of experiments. The problem is extended in a second phase to the coordination of several transport operators with one producer. In this new context, the problem of allocating transport load to different transport operators is integrated into the negotiation process. The complemented models and protocol are validated based on test cases

Freight pricing appears as an important issue for Common transport policy. Firm logistical organisation is influenced by trade-offs in which transport costs make part, and the way firms organise this system directly affects freight flows. This PhD thesis aims to analyse the complex link existing between logistical organisations and freight flows, and to assess the possible impacts of an increase in freight rates on the logistical system and consequently on freight flows. A systemic approach is needed to analyses the role of freight transport costs in the whole logistical organisation. Therefore a system dynamics approach was done for a better understanding of the actual role of transport costs in the logistical system, and to analyse their impact on freight flows. Flows are analysed in tonnes-lifted, tonnes-kilometres, and are also considered in terms of average distances, number of transport links in the networks, shipment size and frequency, and possible flow consolidation

Rouky, Naoufal. "Optimisation et simulation de la massification du transport multimodal de conteneurs." Thesis, Normandie, 2018. http://www.theses.fr/2018NORMLH40/document.
Today, seaports face increasingly stringent requirements imposed by the considerable growth of goods transited by sea. Indeed, the organization of the port sector has evolved rapidly and has caused several negative impacts, including pollution and congestion of terminals, which constitute today the major concerns of port operators. To address those challenges, several ports have decided to build multimodal terminals that act as mega-hubs for maritime terminals, in order to free the storage areas on the maritime terminals, to promote the use of consolidated container modes of transfer and to reduce greenhouse gas emissions by using alternative modes to the road. Nevertheless, the management of these new logistic systems is laborious. This is due to several factors, including the dynamic and distributed nature of these systems, the variety of operations, and the lack of information needed to control flow. The aim of this thesis is to develop approaches capable of meeting the needs of port operators in a multimodal terminal, taking into account the different sources of uncertainty. Two optimization problems are mainly considered in this thesis, namely : the Rail Shuttle Routing Problem(RSRP) and the Quay Crane Scheduling Problem(QCSP). To address the complexity and uncertainties of these problems, we propose new mathematical models, as well as some heuristics approaches based on ant colony optimization, robust optimization and Simulation-Optimization. The various numerical tests carried out proved the effectiveness and the robustness of the proposed algorithms

This research deals with vehicle routing problems in the reverse logistics context. Reverse logistics aims at taking into account both direct flows (from the producer to the customers) and reverse flows (products or equipments sent back from the customers to the producer). We consider multiperiodic problems with time windows where products are delivered from a single warehouse to retail stores, and the stores send products returned by clients as well as handling equipments back to the warehouse. We have developed generic models for distribution and pick up on a network, allowing a variety of options to be tested - cost variations, split deliveries, inventory management by the central warehouse or not. We have developed and compared several solution techniques to solve these problems: classical heuristics, the GRASP metaheuristic and column generation associated with a branch and bound method. The GRASP heuristics and column generation methods have been implemented using both operations research and constraint programming techniques. All our models and solution techniques have been tested on randomly generated instances based on those of Solomon for the CVRPTW and on real-world instances. The obtained results show the relevance of our models for the comparison of different logistics policies as well as for the performance evaluation of the different solution methods, depending on the characteristics of the instances

This thesis studies the node and arc routing problems which are the two main types of routing problems encountered in most transportation applications. We focus particularly on the cases with time windows or split deliveries. This work is divided into two main parts. The first part is devoted to the node and arc routing problems with time windows (VRPTW for the Vehicle Routing Problem with Time Windows and CARPTW for the Capacitated Arc Routing Problem with Time Windows). Contrary to the VRPTW which has been the subject of intensive research over the past decade, few studies have considered the CARPTW. In this part of the thesis, we propose a method based on the metaheuristic GRASP combined with a path-relinking process for the CARPTW and a memetic algorithm for the VRPTW. The second part of the thesis focuses on the node and arc routing problems with split deliveries (SDVRP for the Split Delivery Vehicle Routing Problem and SDCARP for the Split Delivery Capacitated Arc Routing Problem). Since the SDCARP is a relatively new problem, we started by developing mathematical models. We then proposed lower and upper bounds. The lower bounds are obtained by two cutting plane methods while the upper bounds are determined by a memetic algorithm with population management and a new metaheuristic. The memetic algorithm was also adapted to the SDVRP, giving rise to competitive results

This thesis studies extensions of a well-known problem in operations research : the Capacitated Arc Routing Problem (CARP). The CARP involves the routing of vehicles to service a set of arcs (streets) of a network. It has many applications such as waste collection, salt gritting. . . Etc, but it is a short-term problem since it concerns an horizon of one day. The Periodic CARP (PCARP) is the first problem investigated in this work, it extends the CARP to a multiperiod horizon. In this problem, service days must be assigned to the streets under additional constraints before building the trips in each day, to minimise the total routing cost and the fleet size. The second problem that we defined and studied in this thesis is denoted CLARP for Capacitated Location Arc Routing Problem. It involves both strategic, tactical and operational decision levels and consists of determining the positions of depots on the network, from which vehicle trips must be built. We have proposed mathematical models, lower bounds and constructive heuristics for both PCARP and CLARP. A scatter search metaheuristic is conceived for the PCARP and a variable neighbor descent method is proposed for the CLARP. These methods are validated on new benchmark instances

This research aims to define and assess the performance of a different logistics organization: the pooling of supply chains. It implies to design a pooled logistics network within several companies by sharing logistics resources (warehouses, distribution centers, transportation means, etc. ) and logistics systems, in order to improve supply chains' logistics performance. The performance of this new logistics organization was assessed by two criteria: primarily the environmental criteria measured by the CO2 emissions from transport and secondly economic consequences measured by the logistics cost. The difference between environment optimization and economic optimization was also examined. Two cases study were conducted in collaboration with French logistical organizations (Club Demeter and FEEF), respectively based on the major food suppliers and the small and medium food suppliers of the fast moving consumer goods in France. The optimization models for transport optimization aiming to minimize CO2 emissions or logistics cost were formalized and implemented in order to design pooled networks. The results obtained show that the pooling supply chains lead to a significant reduction in CO2 emissions from transport: between -20% and -50% according to the cases studied. The economic performance is less remarkable, but also often more beneficial than the current situation. This performance depends in particular on the relative evolution of transportation costs between rail and road. For example, carbon taxation could allow a better transport allocation from an environment and an economic standpoint

Mesnil, Charlie. "La logistique des armées hellénistiques." Thesis, Lille 3, 2017. http://www.theses.fr/2017LIL30035.
The use of the term "logistics" in its military sense is relatively recent in the historiography of war (it dates essentially from a few decades) and the word is complex to define. To be interested in military logistics isn’t only to be interested in supplying the army, but also in its transport, equipment, housing and sanitary services. These subjects are therefore at the same time varied and very different from each other and the sources aren’t always sufficient. The Hellenistic world we are studying extends from Marseille to Ai Khanoum (Afghanistan) and includes both kingdoms and cities. The spaces concerned influenced the strategic choices of the generals. The impact of military logistics on the outcome of Hellenistic military conflicts is difficult to evaluate and can range from negligible to decisive. Military logistics, however, aren’t limited to their influence in wars, but also concern economic and social issues
Boudia, Mourad. "Coordination de la planification de la production et de la distribution." Troyes, 2006. http://www.theses.fr/2006TROY0012.
This thesis studies an optimisation problematic in supply chain. Usually, production planning is treated without considering the distribution level and handles rarely transportation costs. In the same way, vehicle routing problems suppose that the amounts to be delivered are known and work on a production plan already built. This work presents a coordinated optimisation method in which a production plan and delivery trips are simultaneously built, over several periods. This approach is mostly profitable in sectors where production costs are of the same order as tranportations costs, like livestock feed or fertilizers industry. Two main parts compose this thesis. The first one considers the case with one product. One mathematical model is presented and several heuristics reinforced by local search are developped. More powerful methods based on the GRASP metaheuristic with path-relinking and on memetic algorithms are also elaborated. The second part is devoted to the case with several products and ressources conflicts. A iterative and hybrid approach is developed for this configuration. It is based on the solution of one linear program representing the production planning and on a tabu search metaheuristic with post-optimisation procedures for the distribution level. All the methods presented in this theses for the two cases are validated by an intensive testing. Significant savings are obtained compared to classical decoupled methods, that consider production and distribution separately

Facility location is a strategic decision for supply chain management. In this thesis, we study several basic realistic facility location problems, which include a new variant of capacitated clustering problem (VCCP), facility location problem with single-sourcing (SSCFLP), with vehicle routing (CLRP) and with two stages (TSCFLP). We develop effective methods for finding high quality solutions and tight lower bounds for these problems by improving and extending existing cutting plane methods and applying cut-and-solve (CS) approach and La-grangian relaxation (LR) method. For the VCCP, a LR method coupled with effective multipliers updating techniques, is developed to find its high quality near optimal solution. For the SSCFLP and the TSCFLP, a CS approach combined with cutting plane methods and partial integrality strategy is proposed to their exact resolution. For the CLRP, a new model is proposed. New valid inequalities are identified to strengthen the linear relaxation of the model. A cutting plane method and a partial branch-and-cut approach are developed to find tight lower bounds of the problem. Numerical results show that our algorithms can: 1) produce a high quality near optimal solution for randomly generated instances of the VCCP with average duality gap 0. 51% and 2% in the worst case. 2) find optimal solutions for all benchmark instances of SSCFLP in a few seconds. 3) find optimal solutions for 50 bench-mark instances of TSCFLP for the first time. 4) reduce the optimality gap by 1. 2% on average for the CLRP

This thesis aims to assess the level of legal supervision of logistical activities, to identify the causes of its delay and to propose reflections to update it. In our analysis we referred to the case of French law and of Moroccan law. The results of the research show that there is a significant discrepancy between many varied logistical practices and few legal supervision that has been elaborated for them so far. The causes of this delay are justified largely by the complexity of the logistical activities (application field very broad and heterogeneous) and also by its novelty (systematic innovation in the logistical sector), specific constraints of this new activity which the law did not take really into account.It appears from this assessment analysis that the organizing role of law of economic activities such as the example of the logistical activities is not automatic. The law can act positively and quickly or moderately or not at all. Everything will depend on the quality of the action of law proposed and its ability of supervision and adaptation to the particularities of each activity to be regulated. By referring to the case of logistical activity and to reduce its complexity, we offered several reflections going in the direction of simplification of its application field (reduce the heterogeneity problem) and mastery of behaviours and relations of logistical service providers by groups of families (give more precision about contractual relations in the logistical sector)

The topic of this thesis is about environmental and societal impacts abatement within the green supply chain. This thesis is taking place in the Laboratory of Industrial Engineering and Production of Metz (LGIPM). Our goal is to develop a decision support system in choosing a path with the less environmental and societal impacts. For building our decision support system, we defined a mathematical model which computes for each part in our transportation network, the travel time, the transportation cost and the damage due to transshipment, the amount of greenhouse gas emissions that are emitted, the energy consumption, the noise emitted and the accident risk. From this graph, we built a multiobjective shortest path problem. A multiobjective ant colony algorithm MOSPACO (Ant colony optimization for multiobjective shortest path problem) is then proposed to solve the proposed multiobjective shortest path problem; this new algorithm aims to take into account the large number of criteria and intermodal network. The running of the algorithm gives a Pareto front from which the decision maker can choose his desired itinerary

The two-echelon location-routing problem (LRP-2E) arises from recent transportation applications, especially in urban logistics. We have to simultaneously locate satellite depots (platforms) from a set of potential sites and to build vehicle routes for two levels : first-level trips which serve from a main depot a set of satellites, and second-level trips which visit customers from these satellites. Hence, the LRP-2E combines two types of decisions : strategic (location of satellites) and tactical or operational (construction of vehicle routes at each level of the system). The objective function, to be minimized, is the total system cost, which includes the opening cost of the selected satellites, the fixed costs of vehicles involved and the transportation costs for the tips of the two levels. The motivation of our work is to solve a NP-hard combinatorial optimization problem, still seldom studied in the literature. We propose solution methods, without hierarchy between the two levels, usins constructive heuristics and hybrid metaheuristics, but also an exact approach based on new mathematical fomulrations. The methods developed are tested on sets of instances with up to 200 customers and 20 potential sites for the satellites

The changes that have taken place in the transport business following the appearance of the network company have favoured the growth of new players in the supply chain. As true coordinators of the entire chain, logistics providers have diversified their service offer. From carriers, they have extended their skills to the global control of the end-to-end supply chain, definitively freeing themselves from the transport qualification of the contract that binds them to their customers. Without a legal status, logistic service providers face the silence of the doctrine on the question of the nature of the contract and the legal regime applicable to it. The disinterest of jurists on the issue stems from their ignorance of the logistics whose contours still struggle to be controlled. One of the few solutions proposed is the development of an autonomous status of contracts for the provision of logistics services or the extension of the transport contract regime to these contracts. However, by resorting to the identification of their characteristic performance, it appears that they do not fall under the law of transport but common law, invalidating the thesis of a qualification sui generis

This thesis focuses on the rise of the third party logistics. It does so by proposing answers to three questions: on which economic models relies the organization of the third party logistic? Do the firms belonging to the third party logistic share the strategy defined at the group level? For what reasons logistics and transport activities are outsourced? The thesis is organized in four chapters. The first chapter presents an historical introduction to the logistic activities. It focuses on the merchants and the firms that have handled trade through diverse periods from the Roman Empire to the Industrial Revolution. I described the way used to increase the quality and the quantity of information available to the merchants. The second chapter explains the rise of new economic models to organize logistic activities. The third and fourth chapters present two econometric studies. The third chapter verifies if the firms belonging to a logistic and transport group comply with the strategy of the group. The fourth chapter studies the factors that favor the outsourcing of logistics activities

The present manuscript tackles the supply chain forest transportation problem in the context of forestry primary industry. In this context, several risks may affect the forest supply chain: the unpredictable weather conditions (tree falling provoked by major storms); sanitary emergencies (tree pest and diseases); and, diverse commercial circumstances (the variability of market demands). The aforementioned issues motivate the diverse forest sector protagonists (entrepreneurs, forest operators and drivers) to seek support for improving their logistic operations. The aim of this effort is to improve the service quality (offer-demand agreement) diminishing in this way the total costs. Therefore, the main goal of this thesis is the proposal of a novel management model which improves forest-to-mill transport performance. At the same time, the proposed model accounts for the forest sector manners and constraints. The contribution of this thesis is threefold: first a transportation model is developed, later on the transport planning is managed, and finally an optimization procedure is proposed.The thesis results propose a hierarchical planning for the forestry transportation. Two decision levels are suggested: tactic and operational. At a tactic level, a multi-period optimization is considered. The multi-period optimization strategy meets the customer supply demands while minimizes the global transportation activity. Such strategy takes into account the restrictions of the total available transportation means. Moreover, at this level the activity balancing politics may be developed, as well as subcontractors coordination between transport companies. On the other hand, at the operational level, the tactic planning assigned for each transporter is divided so an optimization of the fleet’s transport assignation is done considering the vehicles constraints.The decision process is modelled as a Mixed Linear Programming formulation. The application considers a data set coming from the industry settled at the Aquitaine region in France. The results have shown a significant improvement on the transport capabilities with respect to the conventional transport practices.It is worth to mention that the decision models were designed such that they may be adapted to different context either collaborative or not. In both cases, the tactic planning has a generic purpose, in other words, it is independent of the kind of organization involved, whereas specific organizations are taken into account when planning actors’ activities at the operational level

In this thesis, we present three extensions of classical combinatorial problems. The first problem is the Vehicle Routing Problem with conflicts which extends the well-known vehicle routing problem by adding incompatibility constraints between customers’ demands. The conflicting demands have to be therefore as-signed to different vehicles. The two-dimensional Bin Packing Problem is also generalized by introducing partial conflicts. A safe distance has to be kept between partially conflicting items assigned to the same bin. The third problem studied is an extension of the two Dimensional Loading Vehicle Routing Problem that considers partial conflicts. Two variants of this new problem are introduced: the first is mono-objective and the second one is bi-objective. In the bi-objective variant, the criterion of load balancing in terms of occupied area in the vehicle is considered in addition to total cost minimization of the routes. Several mathematical models have been pro-posed for these problems. Heuristic and Meta-heuristic methods have also been developed to solve them. A branch and cut algorithm has been used to obtain lower bounds for the vehicle routing problem with conflicts

In this thesis, we study an integrated vehicle routing problem with production management. This problem combines assembly and disassembly operations with the collection of end-of-life products and raw materials. First, we study the deterministic case of the multi-period problem in its static and dynamic version. We propose a mixed integer linear programming model including these new constraints. A two-phase mat-heuristic based on mathematical programming and the variable neighborhood search algorithm is also developed to solve the larger instances. Second, we study the stochastic case where the yield of disassembled components are uncertain due to the unknown status of the returned products. We propose an approach based on robust modeling defined by discrete scenarios. We address different assumptions, where different levels of flexibility are given to different decisions. A three-stage mat-heuristic to optimize the worst case is developed to solve the different problems under all scenarios. Different tests are performed to show the effectiveness and limitations of each approach in each case

The premises of our research can be described through a two-fold professional challenge. The France is under-equipped in terms of removable containers. What should be done to reduce this handicap? The S. C. M. (Supply Chain Management or global logistics) software are out of reach for small and midsize companies. How can they be organized in order to make them accessible? Our paper is designed in five parts: the introduction presents the teilhardian weltanschauung, the axiomatic of our research, the refutations of the "true thought", the modelling leads of the object and, the validation by the satisficing. The theoretical corpus of out thesis is founded on three theories : the constructivism, the General System, Simon "administrative " theory. We chose the field of the consular Chambers. We realized that the construction from scrap of a network is not realistic in the context of our thesis which led us to propose the systemic metaphor of the "Chambre de métiers" of Haute-Savoie

Cette thèse est une contribution à la modélisation, la planification et l’optimisation du transport pour l’approvisionnement en bois de forêt des industries de première transformation. Dans ce domaine, les aléas climatiques (mise au sol des bois par les tempêtes), sanitaires (attaques bactériologiques et fongiques des bois) et commerciaux (variabilité et exigence croissante des marchés) poussent les divers acteurs du secteur (entrepreneurs et exploitants forestiers, transporteurs) à revoir l’organisation de la filière logistique d’approvisionnement, afin d’améliorer la qualité de service (adéquation offre-demande) et de diminuer les coûts. L’objectif principal de cette thèse était de proposer un modèle de pilotage améliorant la performance du transport forestier, en respectant les contraintes et les pratiques du secteur. Les résultats établissent une démarche de planification hiérarchique des activités de transport à deux niveaux de décision, tactique et opérationnel. Au niveau tactique, une optimisation multi-périodes permet de répondre aux commandes en minimisant l’activité globale de transport, sous contrainte de capacité agrégée des moyens de transport accessibles. Ce niveau permet de mettre en œuvre des politiques de lissage de charge et d’organisation de sous-traitance ou de partenariats entre acteurs de transport. Au niveau opérationnel, les plans tactiques alloués à chaque transporteur sont désagrégés, pour permettre une optimisation des tournées des flottes, sous contrainte des capacités physiques de ces flottes. Les modèles d’optimisation de chaque niveau sont formalisés en programmation linéaire mixte avec variables binaires. L’applicabilité des modèles a été testée en utilisant un jeu de données industrielles en région Aquitaine et a montré des améliorations significatives d’exploitation des capacités de transport par rapport aux pratiques actuelles. Les modèles de décision ont été conçus pour s’adapter à tout contexte organisationnel, partenarial ou non : la production du plan tactique possède un caractère générique sans présomption de l’organisation, celle-ci étant prise en compte, dans un deuxième temps, au niveau de l’optimisation opérationnelle du plan de transport de chaque acteur.

Guerrero, Rueda William Javier. "Models and optimization methods for the inventory-location-routing problem." Thesis, Troyes, 2014. http://www.theses.fr/2014TROY0002/document.
The problem of designing a supply chain including simultaneously routing and inventory management decisions is studied in this thesis. The objective is to select a subset of depots to open, the inventory policies for a 2-echelon system, and the set of routes to perform distribution from the upper echelon to the next using a homogeneous fleet of vehicles over a finite planning horizon. Demand is considered to be known. Applications are found in humanitarian logistics and military logistics. To solve the problem, two matheuristic procedures are developed. On the first part a cooperative algorithm combining exact methods for the supply chain design problem and routing heuristics is presented. On the second part, a partition is proposed using a Dantzig-Wolf reformulation on the routing variables. An hybridization between column generation, Lagrangian relaxation and local search is proposed in this part, put together as a heuristic method. Furthermore, results demonstrate the capability of the algorithms to compute high quality solutions and empirically estimate the improvement in the cost function of the proposed model when compared to a sequential optimization approach. Furthermore, results of the proposed methodologies on benchmark instances for subproblems are studied as well. Those are the capacitated location-routing problem, the inventory-routing problem, and the generalized elementary shortest path problem

The problem we study is inspired by an industrial collaboration between a third-party logistics, DHL Supply Chain, and a large French restaurant chain. As part of this partnership, DHL Supply Chain coordinates the actors of a domestic logistics network composed of suppliers, warehouses and restaurants. Over a certain time horizon, the restaurants issue requests of generic products (frozen products, beverages, etc.) that are manufactured by the suppliers. The mission of DHL Supply Chain is to ensure the supply of the restaurants. For that purpose, the company determines the shipping origin of each product ordered and designs a loading plan that characterizes the routes followed by the goods. DHL Supply Chain wants to develop innovative solutions to improve its competitiveness and optimize the profitability of its logistics operations. In this thesis, we present the Logistics Service Network Design Problem (LSNDP) which formalizes the problematic of planning transportation operations in a supply chain. Our work aims to provide methodological solutions for solving industrial instances of the LSNDP. However, these industrial instances are too complex to be solved by generic operations research methods. We thus propose several algorithms that overcome the scaling of the parameters. In particular, we develop a graph reduction heuristic, as well as a dynamic Benders strategy that adapts to the increasing number of products. Through various computational studies, we evaluate the scalability of each algorithm with respect to the considered parameter. Finally, we combine these methods for the resolution of a real case

This thesis presents a new problems inspired by a real case, we introduce two-echelon multi-depot, multi-vehicles Inventory-Location-Routing problem (2E-MDILRP) for a specific type of perishable product, proved to be NP-hard. In addition, we studied the taxonomy of the sub problems of 2E-MDILRP, and we propose the different constraints of perishable products. This taxonomy would, on the one hand, provide better understanding of the 2E-MDILRP of the perishable products, and on the second hand identify promising further research topics. So, a mathematical model has been proposed and validated using the OPL\Cplex solver for this new variant. Also, we proposed a specific heuristic developed with iterated local search algorithm (ILS) using to solve the new 2E-MDILRP problem. This is tested within a theoretical framework, the under a real empirical framework. The latter consists in optimizing the perishable product distribution and inventory. These developed methods have been tested on sets of instances of up to 4 main depots, 20 potential satellites and 200 customers, with two fleets of heterogeneous vehicles available at a rate of one fleet for each level. The results of our exact and approximate method show the efficiency of the approach
