Yang, Bo. "Numerical investigation of restricted curved waterways on ship hydrodynamics for maneuverability considerations." Electronic Thesis or Diss., Compiègne, 2023. http://www.theses.fr/2023COMP2735.
Повний текст джерелаInland waterway transport is now playing a significant role thanks to its various advantages over the other transportation modes, for example, low cost, low environmental pollution, and large capacity, etc. However, inland waterways are not only naturally curved but also narrow and shallow, which causes complex flow environments and navigational conditions. Inland ships are consequently susceptible to accidents in restricted curved waterways. Especially during these years, this mode of transport has seen significant progress by the arrival of the new generation of ships (larger size and more powerful), and this makes ships’ maneuverability in such sensitive waters severer. To conduct this investigation, the CFD model based on an unsteady Navier-Stokes solver in STARCCM+ is used. The verification and validation of this model are realized by respecting the ITTC recommendations. The latter is then used to perform a series of simulations by testing the following key parameters: a series of navigational environmental parameters, including channel angle, channel bottom width, channel slope angle; a set of parameters related to ship behaviors and geometry, containing water depth to draft ratio, ship speed, drift angle and ship type (ship length) on ship hydrodynamics in restricted curved fairways. Relative frame motions are applied to the computational domains to produce centrifugal force in bending fairways. The aim of the present thesis is firstly to characterize the variables connected to a circular channel's topology that have a substantial impact on a ship's maneuverability. Second, it helps to well understand the flow behaviors that occur around a ship in bending zones. Thirdly, the fluctuations in hydrodynamic force (bank cushion and suction phenomena) and the sensitivity of a number of variables in bending zones are investigated. Finally, the inland ship simulator is improved by adding the bending zone effect for pilots, so that the behaviors of ships in the sensitive regions can thus be corrected

Повний текст джерелаThis thesis discusses the Inland Waterway Transport (IWT) as ecological and sustainable response to the problem of the saturation of the road and its importance in terms of social welfare. It is first to identify the place of the inland waterway in the chain of transport, to distinguish the strengths and weaknesses of this mode in France and followed strategies and those needed to modernize and to promote inland waterway transport. At the European level, it will show the place occupied by inland waterway in public policies and identify the tracks of intra-European cooperation to develop this mode and enable it to achieve the place that it deserves in the transport chain. Secondly, study the opportunities and barriers to modal transfer and upgrade the prerequisites for the landslide of goods to the waterway seem necessary to ensure the full integration of it in intermodal chains, this work will treat as the importance of inland waterway logistics and the channels of its development

Повний текст джерелаThis PhD work deals with land mobile satellite channel modelling and addresses the specific issue of satellite navigation systems in urban environments with a particular focus on multipath modelling and wide-band representation of the channel. The developed land mobile satellite channel simulator, SCHUN (Simplified CHannel for Urban Navigation), is based on a hybrid physical-statistical approach satisfying fast computation requirements. The statistical component of the modelling is mainly used during the virtual city synthesis step based on known statistical distributions of building height and street width. The rest of the modelling comes from deterministic methods using simplified electromagnetic interaction models reproducing building macro-scattering (3CM model (Three Component Model)) and building blockage of the direct path. The main underlying electromagnetic methods are the physical optics and the uniform theory of diffraction. The SCHUN simulator now opens interesting perspectives for the modelling of wide-band land mobile satellite propagation channel in dense urban environments. Optimised for pseudo real-time constraints, it uses both physical and statistical approaches. Furthermore, the SCHUN simulator has been designed and validated against measurements to answer specific needs of satellite diversity, receiving diversity, polarisation diversity or frequency diversity for satellite navigation applications

Повний текст джерелаSea-river shipping is a form of short-sea transport and an interesting multi-modal transport. Its concept is simple: one vessel sails both coastal and inland waters. Sea-river ships can connect the hinterland with overseas destinations without the need for an intermediate transhipment. As a result, transport costs are lowered and the risk of damage due to handling is reduced. Nevertheless, sea-river shipping has not been significantly developed in Europe (Rissoan, 1994, 1995). Substantial traffic volumes are only found on a very limited number of routes (e. G. Rhine; some Russian waterways). In France, it is restricted to a very limited number of waterways, such as the Seine or the Rhône-Saône basin. On the Rhône-Saône corridor, sea-river shipping can directly connect inland ports with Mediterranean seaports. Then, it offers “Rhône valley-Mediterranean” logistics. Rissoan (1987) tries, for different products, to define the competitive navigational area of sea-river shipping (including river and maritime trips). Konings and Ludema (2000) evaluate the opportunities for sea-river shipping on the United Kingdom – Germany corridor (Rhine). They examine its competitiveness with regard to a number of alternative transport modes. Nonetheless, there is no study which calculates the volume that divides the transport market between sea-river shipping and a “river + sea” alternative. A reasonable question arises: at which threshold, in terms of tonnage, are sea-river vessels more efficient than barge+shortsea transport service? Comparing the returns to scale of each transport chain, we define this tipping point. The costs production function is taken from Cullinane – Khanna (2000) and Stopford (2002). After addressing this question, we determine, for different ports of the Rhône-Saône corridor, the maximum sea trip that is efficient for a sea-river vessel (as a function of tonnage). After Rissoan (1987), we define the competitive navigational area of sea-river shipping. Our specific contribution is to consider the nautical access offered by inland ports along the Rhône and the Saône

Повний текст джерелаThe Rhone River, in conjunction with its tributary the Saone River, form an axis of penetration inside the Gaul used during the Roman period to link the Mediterranean sea to the north of the empire. Short land connections enabled the trades to flourish over the basins of the Loire, the Seine, the Rhine and the alpine lakes. Short land connections have allowed the pursuit of the trades over the basins of the Loire, the Seine, the Rhine and the alpine lakes. Only the southwest quarter seems to have escaped the influence of the Rhone. This corridor formed the major artery of the Gallic river network, even before the Roman conquest. The waterway at the time was the primary means for transporting goods inland, up until the arrival of the railway. The Rhône and Saone rivers alone would have conveyed nearly half of river traffic of all Gaul. These waterways have also clearly contributed to the development of riverside towns often corresponding to river stops and points of cargo redistribution. The interest of the subject is of paramount importance. The intention of this work is threefold. First, provide an overview of the navigation of the Rhone and the Saone as evidenced by series of discoveries of the 2000s (Lyon and Arles wrecks) ; then disprove two commonly held misconceptions of the Roman "landlubber": the use of archaic navigation technique and the ease of the river environment. Finally, the main intention is to show the specifics of navigation on the Rhone and Saone in Roman times. This will be covered in three parts. A first part related to the navigation parameters (goods, packaging, crafts, corporations, river environment) to identify in detail the characteristics and issues related to each of them. A second part is dedicated to given navigation conditions : weather, boat morphology (draft, air-draft), dynamic conditions (possible propulsions), legal and religious conditions, risk of attack, etc. Based on the navigation parameters and navigation conditions presented, the last part describes the possibilities of navigation that were offered at that period. It is a tool to simulate transport situations. The reader has the option to "compose" a transport scenario by selecting the parameters of the first part, and by confronting them to the navigation conditions of the fluvial axis defined in the second part. In the end, it is possible to to give answers to several questions such as the use of oar or sail against the current, the possible drafts that could be used, the presence of marine ships or dolia ships upstream of Arles, the most favorable conditions to barge navigation, the speed or travel time

Повний текст джерелаAs well as being a means of regaining legal ground in the Middle Ages, rivers under royal supervision were instruments of modelisation within the state system as much for the territorial make up and the setting up of borders as for the modes of administrative penetration. Contrary to received wisdom, the establishment of French laws governing the rivers of the Crown stems from a geography of sovereignty. From the beginning of the concept of “bien domanial par nature”, the introduction of public laws codified as early as the “Ancien Régime”, reveals the importance and the history of "matters of water" in the origins of the theories regulating the state property within administrative laws. Also the river system model pioneered a tradition unknown to the specialised lawyers and public law professionals who took part in the creation of the first classification nomenclatures and the rising systemization of administrative laws under the Restauration. This research proposes for the first time, at the turning point of survival, economic and defence stakes, a history of public laws on river

Повний текст джерелаWith the increasing demand for urban space, more and more multistory carparks are needed. Although these carparks help to utilize urban space more efficient, they also introduce a new problem. Reports suggest approximately 70 million hours of parking slot searching each year, equivalently 700 million euros loss for France alone. In addition, carparks uses are exceeding their original purposes. Demanding features such as electric charger, online booking of parking spaces, dynamic guidance or mobile payment etc. turn a carpark into a competitive smart environment. One solution to this problem is to develop an autonomous navigation system for intelligent vehicles in the carpark situation. The thesis will identify one of these sub-tasks namely localization in GPS-denied environments. This thesis will present a novel method to solve the indicated problem while keeping the system follows four criteria: availability, scalability, universality and accuracy. There are two main steps: (1) a solution to replicate the GPS behaviour for the GPS-denied environment, and (2) a framework that allows the fusion of GPS-like systems with other localization methods to achieve a high localization accuracy. First, a Wi-Fi Fingerprinting localization system is employed. An approach using an ensemble neural network on a hybrid Wi-Fi fingerprinting database is proposed in this thesis. Experiments in a year-long duration show that this system is capable of localizing vehicles with 2.25m of mean error in the global coordinate frame (WGS84). Second, a complete localization solution must be a fusion of multiple techniques. This allows global as well as local levels of localization to function together. At the same time, having redundancy in the system boosts accuracy and reliability. In this thesis, a flexible fusion framework for multiple localization sensors is proposed. This fusion framework will not only deal with the GPS-denied environment but could be potentially used in the GPS-aided environment and provide a smooth transition between the two areas. To accomplish this demanding task, a Gaussian Mixture Model Particle Filter is developed. While the motion model of this particle filter incorporates data from the IMU (Inertial Measurement Unit) or laser-SLAM, the correction model is a Gaussian mixture model of multiple observations obtained from the Wi-Fi fingerprinting localization system. With two intelligent vehicles (a Cybercar and a Citroen C1 car), 64 experiments were carried out to validate the framework. A mean localization error of 0.5m is achieved in a global coordinate frame. Compare to other solutions with 0.2m of mean localization error in local coordinate frames; this proposed solution has advantages in terms of scalability, availability and universality as well

Повний текст джерелаThis study deals with shipping, navigability and river engineering on the river Loire between Briare and the confluent with the river Vienne, from the end of the 18th century to 1918. This part of the river, which is well connected to the capital, comes within the context of commercial exchanges, including a large part of the territory, some of then supplying the french foreign trade. But navigating on the Loire is very restricting : the rates of flow are irregular, low in summer. To maintain and regulate the fairway become a necessary matter. The intervention of the State and its corps of engineers deprives the Community of merchants (abolished in 1772) of its privileges. Thanks to changes of action in favour of navigability, we can distinguish 3 periods. Before 1820, to maintain the river is the main concern. From 1820 to 1852, because of the innovations of the “marine de Loire” – improvements on sailings boats, steam boats – engineers must build submersible dikes. As they make the fairway narrower, they must make shipping possible all the year round. A special service for the river Loire is created, banks protection and fitting out of ports are encouraged. The disappointing results of the work done on the river, the expansion of the railway, which ruins the shipping on the Loire, cause a crisis in the river engineering. Between 1852 and 1918, plans for building work and ship canal fails. The action of two groups of opinion – one who defend the navigation on the river and the other one who is in favour of the building of a canal – and the boosting of new work to make the lower part of the river navigable would not stop this crisis and the decay of navigation

Повний текст джерелаIf, for Hennebont, 1660s and 1780s were marked by an erosion of the maritime business, this form of decline is part of a much broader phenomenon of gradual decommissioning of the small ports of estuary background; in this case it is for the benefit of the new neighbour Lorient. However it, appearing first as a new competitor, can also be a source of opportunities, providing work for local labor and new market opportunities, with the capture of some of the products traditionally exported (wood, food...). On the other hand, there’s also new links between East India Company and local craftsmen (provision of nails or utensils in Tin, for example). Hennebontais traders know also seize new opportunities that offers them trade overseas; If they keep the hand on their traditional activities, the company becomes a new interlocutor that it is interesting to satisfy and which offers lucrative investment opportunities. Taking in charge the destiny of city, traders transformed the city council to their advantage, they launch a policy of major works, allowing the port to become a more effective tool and take a new look on the City. Opening to the world and the influence of the nearby town also have an impact on the daily life of the population through consumption of new products, the trades, the movement of ideas including care, promoting the presence of minorities

Повний текст джерелаNatural link between Rennes and the sea, the river Vilaine in the early modern period was only navigable in its lower valley. From the ocean, vessels flowed in the river Vilaine estuary to Redon harbour. Upstream, small boats could reach Messac harbour, which was the term of the waterway. Further upstream, Rennes is located about thirty kilometers from Messac. Most city of Brittany, Rennes didn’t take full advantage of its situation on the banks of the river Vilaine. In the 16th century, the city council instigated the river Vilaine development between Messac and Rennes. The aim was to relate Rennes to the river-sea shipping. At the end of the 16th century, the river Vilaine was sustainably channeled thanks to a modern lock system. Navigation expanded to the city of Rennes. In the 17th century, the waterway became an essential supply line for Rennes

Повний текст джерелаThis thesis presents an experimental study of the effects of the waterway confinement and the current on ships wakes and drag. Two generic hulls representative of maritime and river ships have been studied in several bathymetric configurations in the towing tank of the Institut Pprime. Optical measurement methods based on a stereovision principle have been set up to measure the free surface deformations. The spatial extent and the resolution permits to lead a fine analysis of the wakes in the spectral space in order to decompose them into a hydrodynamic component and an undulatory component, respectively in the near-field and the far-field of the ship hull. The results obtained in a deep waterway configuration highlight the non-linearity of the ship wakes, which results in a modification of the shape of the envelop of the wave field in the real space. The results obtained in a shallow waterway configuration show a modification of the shape of the ship wakes and a different distribution of the energy between the wave systems. The influence of the shape and the speed of the ships on the amplitude of the hydrodynamic response and the return current is also identified. The comparison of the measurements in the presence of a counter-current with the results in calm water show an increase of the amplitude of the waves and an enlargement of the wash zone on the walls of the canal. Drag forces measurements with a multicomponent dynamometer give access to resistance curves for each configuration. The increase of the ship resistance in shallow water is put in parallel with the increase of the amplitude and the wavelength of the transverse waves
Linde, Florian. "3D modelling of ship resistance in restricted waterways and application to an inland eco-driving prototype." Thesis, Compiègne, 2017. http://www.theses.fr/2017COMP2389/document.
Повний текст джерелаAn eco-driving prototype, named EcoNav, is developed with the aim of optimizing a vessel speed in order to reduce fuel consumption for a given itinerary. EcoNav is organized in several modules : - a 2D hydraulic model simulating the flow conditions (current speed and water depth) along the itinerary; - a ship resistance model calculating the thrust necessary to counteract the hydrodynamic forces ; - a fuel consumption model calculating the fuel consumption corresponding to the thrust input; - a non linear optimization algorithm calculating the optimal speed profile. In order to evaluate the fuel consumption of an inland vessel, a ship resistance numerical model is developed in the first part of this PhD. This 3D numerical model simulates the flow around an inland self-propelled vessel and evaluates the hydrodynamic forces acting on the hull. A RANS solver is coupled with a quasi-Newton approach to find the equilibrium position and calculate ship sinkage. This method is validated by comparing the results of numerical simulations to towing tank tests. The numerical results with and without sinkage are also compared to study the influence of sinkage on ship resistance and on the accuracy of the method. Additionally, some empirical models are investigated and compared with the accuracy of the numerical method. Finally, the numerical model is used to determine if channel with and water depth restriction contribute to the same amount of ship resistance increase for the same level of restriction. The results of that investigation give insight to whether channel restriction can be characterized by a unique parameter (for instance the blockage ratio) or two parameters to distinguish water depth and channel with effects. In the second part of this PhD, the numerical methods used in the speed optimization model are described and validated. The speed optimization model is then used to simulate a real case: the itinerary of the self-propelled ship Oural on river Seine, between Chatou and Poses (153 km). The optimized fuel consumption is compared with the non-optimized fuel consumption, based on AIS speed profile retrieved on this itinerary. The effects of the ship trajectory and travel duration on fuel consumption are also investigated. The results of those investigations showed that optimizing the ship speed lead to an average fuel saving of 8 % and that using an optimal track and including real time information such as lock availability and river traffic can lead to additional fuel savings
Du, Peng. "Numerical modeling and prediction of ship maneuvering and hydrodynamics during inland waterway transport." Thesis, Compiègne, 2018. http://www.theses.fr/2018COMP2459.
Повний текст джерелаIn this thesis, the ship hydrodynamics during inland waterway transport and ship maneuvering are investigated using CFD (Computational Fluid Dynamics) based onOpenFoam. Validation and verification studies are carried out for the mesh convergence, time step convergence, sensitivity to turbulence models and dynamic mesh techniques. A quaternion-based 6DoF motion solver is implemented for the trim and sinkage predictions. Environmental effects on several inland vessels (convoy 1, convoy 2, tanker) are studied using the validated numerical models. Three important aspects, the confinement effect of the waterway, head-on encounter and ship-bridge pile interaction are simulated. The testing conditions cover a wide range, including various channel dimensions, water depths, ship draughts and speeds. The ship resistance, wave pattern, Kelvin angle and wave elevation at specific positions are investigated as functions of these parameters. Ship maneuvering is investigated using virtual captive model tests based on the MMG (Mathematical Maneuvering Group) model. An actuator disk is implemented to replace the real propeller. Open water test, rudder force test, OTT (Oblique Towing Tank test) and CMT (Circular Motion Test) of a KVLCC2 model are carried out to obtain the hydrodynamic coefficients of the propeller, rudder and ship hull. Using the obtained coefficients, system-based maneuvering simulations are carried out and validated using the free running test data. These studies reproduce real ship tests and thus prove the validity of our numerical models. As a result, the numerical solver is promising in ship hydrodynamics and marine engineering simulations

Повний текст джерелаThis thesis deals with interaction between human and informed virtual environment (IVE). An IVE is a virtual environment including knowledge, which is, in our case, linked with virtual objects (Smart Objects). The purpose of this thesis is to enhance the coupling between human and IVE by allowing it to relevantly react to user’s behavior. To do so, we add to the IVE a decision-making module which is able to choose, in real time, a multimodal feedback (a set of aids) according to user’s activity which is observed by the system by using various sensors. We choose the belief function theory for decision-making in order to deal with the uncertainty and the incompleteness of collected data describing user’s behavior. In this way, our system brings an informed interaction: the reaction of the system to user’s actions is based on a priori knowledge combined with other knowledge acquired in real time. Thus, we bring a personalized interaction, adapted to each user, to increase its efficiency. The decision-making module includes an evidential network with conditional belief functions allowing graphically representing influences, a priori known, between different variables of the system. Input variables correspond to data collected in real time about the user: his/her actions and physiological state. These data can be uncertain (ex: data coming from sensors with some reliability) or incomplete (ex: failure of one of the sensors). The belief function theory allows us to represent these data with the uncertainty and the ignorance which are associated. These beliefs are then propagated in the evidential network to obtain, in output, a belief on the utility of the triggering for each available multimodal aid. The choice concerning the display of a set of multimodal aids, among those having an important utility, is done by solving a constraint satisfaction problem. Indeed, the set of multimodal aids to choose must respect a set of constraints which are a priori or dynamically set up. This allows ensuring the adequacy of the chosen solution with the system (ex : some aids can be incompatible with each other) and the adequacy with the user (ex : user’s sensory canals should not be overloaded with too many aids). Depending on the complexity of the problem, a good solution, without guarantee about its optimality, is computed by a genetic algorithm so as to be able to propose a feedback in a short due time. An information file for each user is created a priori and then updated by the system according to an estimation of the user’s preferences about the aids. These preferences are respected at best for the choice of the aids. This work has been applied to a fluvial navigation simulator in order to bring a training module allowing giving a personalized interaction to the learners with the simulator. The learner’s behavior is interpreted by the system (actions on ship controls, navigation errors determined from an estimation of the future position of the boat, stress level, etc. ) and with these data the decision-making system determines the most appropriate multimodal feedback according to the current situation. The aids proposed can be, for example, visual assistances, audio messages and simplifications of the navigation conditions in order to help the learner to anticipate the maneuvers to do. On the contrary, in the case of experienced learners, the decision-making system will rather choose to remove assistances and to increase the navigation complexity. This personalization of the feedback for each learner brings autonomy in the training allowing a trainer to follow several learners at the same time. Other applications of our work could be considered such as, for example, driving assistance in augmented reality. An experiment has been realized to evaluate the contribution of our system for learners of different levels. Our system has been compared to a system without aids (control system) and to a system with non-adaptive aids. The results show that, between the beginning and the end of the training, novice learners obtained a two-time greater score with our system in comparison with the control system. The system providing always the same aids (training without adaptation) did not allow the learners to improve themselves. The learners’ questionnaire answers and the trainers’ comments show a real interest of our approach

On note à Abidjan une séparation des fonctions, les emplois étant concentrés dans les quartiers au Sud de la ville tandis que le Nord constitue une zone résidentielle. Dans un tel contexte, le défi est donc de savoir quels sont les voies et moyens pour rendre le transport public efficace et durable.
Cette thèse vise l'accroissement et la diversification de l'offre de transport en commun par l'utilisation du plan d'eau lagunaire pour désengorger les voies terrestres, le développement de moyens de transport alternatifs, la lutte contre la pollution de l'environnement. Elle vise à promouvoir le transport lagunaire de personnes comme une solution aux problèmes de mobilité qui se posent à la population abidjanaise et à susciter un transfert modal d'autres modes de transports — tels que les voitures particulières, les bus, les taxis, les taxis wôrô-wôrôs — vers les bateaux-bus.
On note actuellement que l'exploitation du plan d'eau lagunaire est encore à l'état embryonnaire malgré la présence de la lagune dans onze des quatorze communes que compte le district d'Abidjan.

Although the Ile-de-France region is disadvantaged in terms of infrastructure and maritime ports opportunities facing the countries of Northern Europe, Seine river traffic is growing. A large river metropolis and a set of inland ports may explain this feature. This doctoral thesis aims to identify how river ports have followed a different organization from other European territories, due to the presence of Paris. It is therefore useful to use both statistical analysis of port traffic and interviews with Port Authority and metropolitan actors, to identify contradictions in their expectations and their respective approaches. The results highlight an adaptation of inland port to the needs of the metropolis, through traffic specialization and networking, in order to justify their presence in urban areas. Hence, the Port Authority Ports de Paris has developed a policy planning to ensure urban integration of its inland ports. However, lack of coordination and understanding between Port Authority and urban actors are the main obstacles to the acceptability of inland ports in metropolitan areas

Повний текст джерелаIn the present study, three archetypal boats called baleinière, chaland and sharpee are observed in the west area and the equatorial area of Africa. They sail on the rivers of Sénégal, and Niger ; on Oubangui, Chari and Chad lake, between seventeenth century and contemporary period. The whole of waterways measure eight thousand kilometres of Iength. The three previous occurrences suggest a relationship between Europe, America and Africa, these continents linked by Atlantic ocean, are called "foyers of traditions". Manuscripts, stories of the first voyagers, publications, plans, charts, iconography are examined. Then, the collector's item of baleinière du Chari showed in Musée des troupes de marine, Fréjus, France is looked over in detail. The study analyses the architectural characteristics of boats, the aquatic mobility, the reasons of this mobility and the intelligence put into practice. It makes an inventory of vernacular nautical traditions and examines their harmony with natural environment and the daily life of men. Geography, history, ethnography allow to determine local area, genesis, architecture, functionality, and the use of boats. The result elucidates the process of cultural and technical mix of baleinière, chaland and sharpee. The ethnographic survey substantiates the genesis of chaland sablier currently built nearly Bamako city

Повний текст джерелаThe Port of Paris does not correspond to the traditional definition of the term. It should first be noted that this is a river port. The difficulty of defining the port of Paris stems from the fact that it consists of several types of installations: canals, ports at docks, ports on banks (straight wharves and pull ports) and therefore protean realities. Some authors prefer the term "ports of Paris" to emphasize its heterogeneous character. In the 19th century, we also talked about the "ports of Paris", that is to designate installations on the Seine, as opposed to canals. The port of Paris thus corresponds to an ensemble bordered by some sixty kilometers of shore, including a part intended for inland navigation This thesis begins at a time when river transport is confronted with the effects of competition from the railways. It will take several decades to adapt and take on a new function, namely the almost exclusive role of provider of weighty. This conversion was mainly achieved through the improvement of river infrastructures. Port modernization had two aspects: improving tooling to optimize the packaging of goods, and integrating a more global vision of the function of the port of Paris, and even of Paris itself. "Paris sea port" belongs to the latter. One can put forward the idea of an opposition between a "real port" and a "mythical" port, an alternative way of transforming the port's vocation to the capital. Attempts at reconciliation between these two visions are manifested through the creation of the port of Ivry, commissions between 1911 and 1914 on the modernization of port equipment

Повний текст джерелаBarge transportation is an important research topic that started to draw increasing scientific attention in the recent decade. Considered as sustainable, environment-friendly and economical, barge transportation has been identified as a competitive alternative for freight transportation, complementing the traditional road and rail modes. However, contributions related to barge transportation, especially in the context of intermodal transportation, are still scarce. The objective of this thesis is to contribute to fill this gap by proposing a reactive decision support system for freight intermodal barge transportation from the perspective of the carriers. The proposed system incorporates resource and revenue management concepts and principles to build the optimal set of scheduled services plans at the tactical level. Carriers may thus benefit from transportation plans offering increased flexibility and reliability. They could thus serve more demands and better satisfy customers. One novelty of the approach is the application of revenue management considerations (e.g., market segmentation and price differentiation) at both operational and tactical planning levels. The optimization problems are mathematically formalized and mixed integer linear programming (MILP) models are proposed, implemented and tested against various network settings and demand scenarios, for each decision level. At the tactical level, a new solution approach, combining adaptive large neighborhood search (ALNS) and Tabu search is designed to solve large scale MILP problems. An integrated simulation framework, including the tactical and the operational levels jointly, is proposed to validate the decision support system in different settings, in terms of physical network topology, revenue management parameters and accuracy degree of demand forecasts. To analyze the numerical results corresponding to the solutions of the optimization problems, several categories of performance indicators are proposed and used
