Abstract:

Thesis (Masters Diploma (Electrical Engineering) -- Cape Technikon, Cape Town,1991
The main reason for this project was "import replacement", as all our existing Point of Sale and Electronic Equipment had to be imported from Japan. After the Government I s steps to curb imports by placing extremely high levies on imported goods, it was decided to produce a completely local product. From past experience it was obvious that customer requirements varied greatly. This gave rise to the inception of a modular system, enabling the customer to "mix and match" modules to their requirements. The"concept is to use a HOST computer controlling a differential communications line with a maximum of 255 terminals which are all individually addressable. Each individual terminal would in turn control an internal differential communications line, called PNET, which is an acronym for "Peripheral Network". A decision was made to make all the peripherals intelligent, thereby alleviating the processor of all menial tasks. All peripherals local to the terminal would be connected to this network. The configuration can be seen graphically by refering to Figure 0-1. The communications protocol used is more sophisticated than that used for RS232 devices. The protocol has a POLL - ACKNOWLEDGE structure, where the HOST has complete control of the loop.

Abstract:

Context: The workload at seaport container terminal is increasing gradually. We need to improve the performance of terminal to fulfill the demand. The key section of the container terminal is container stacking yard which is an integral part of the seaside and the landside. So its performance has the effects on both sides. The main problem in this area is unproductive moves of containers. However, we need a well-planned stacking area in order to increase the performance of terminal and maximum utilization of existing resources. Objectives: In this work, we have analyzed the existing container stacking system at Helsingborg seaport container terminal, Sweden, investigated the already provided solutions of the problem and find the best optimization technique to get the best possible solution. After this, suggest the solution, test the proposed solution and analyzed the simulation based results with respect to the desired solution. Methods: To identify the problem, methods and proposed solutions of the given problem in the domain of container stacking yard management, a literature review has been conducted by using some e-resources/databases. A GA with best parametric values is used to get the best optimize solution. A discrete event simulation model for container stacking in the yard has been build and integrated with genetic algorithm. A proposed mathematical model to show the dependency of cost minimization on the number of containers’ moves. Results: The GA has been achieved the high fitness value versus generations for 150 containers to storage at best location in a block with 3 tier levels and to minimize the unproductive moves in the yard. A comparison between Genetic Algorithm and Tabu Search has been made to verify that the GA has performed better than other algorithm or not. A simulation model with GA has been used to get the simulation based results and to show the container handling by using resources like AGVs, yard crane and delivery trucks and container stacking and retrieval system in the yard. The container stacking cost is directly proportional to the number of moves has been shown by the mathematical model. Conclusions: We have identified the key factor (unproductive moves) that is the base of other key factors (time & cost) and has an effect on the performance of the stacking yard and overall the whole seaport terminal. We have focused on this drawback of stacking system and proposed a solution that makes this system more efficient. Through this, we can save time and cost both. A Genetic Algorithm is a best approach to solve the unproductive moves problem in container stacking system.

Abstract:

This thesis reports the results of the investigation on the practical implementation of the intelligent Quadrifilar Helix Antenna (IQHA). The research work has covered many aspects on practical issues for utilising the IQHA at the mobile terminal. The investigations were carried out through simulations and measurements, with main emphasis on the measurement results such that mobile phone manufacturers can utilise and progress directly to product development. The research work is divided into three parts, namely, the QHA structure, the intelligent algorithm and the development and performance evaluation of the IQHA demonstrator. One of the challenges was to reduce the physical size of the conventional Quadrifilar Helix Antenna (QHA) structure, such that it is small enough to be implemented onto a mobile terminal device. The QHA structure also needs to be able to operate in more than one frequency band. The QHA structure was successfully reduced by more than 50% using the meander line technique with slight reduction in efficiency and tremendous increase in operating bandwidth. The spur-line band-stop filter technique is used to create dual resonance for the reduced size QHA structure. These two techniques have been patented and can both be applied independently. The intelligent algorithm for the IQHA is studied through simulations. An adaptive combining algorithm based on Least Means Squares (LMS) is proposed to perform real-time diversity combining and is implemented into the micro-controller of the IQHA demonstrator. It was observed through measurements in the downlink that the IQHA is able to perform diversity combining and cancellation of deep fades in realtime. In the uplink, the real time demonstrator uses the micro-controller to feed the appropriate weights through the digital phase shifters on the individual branches of the IQHA system to perform beam steering. The approach relies on producing a variable radiation pattern by adjusting the phase relationship between the individual elements of the IQHA. Beam steering gains relative to the standard QHA configuration were observed using the optimised weighting configurations.

Abstract:

Airport operation level of service (LOS) and performance management are among the major concerns by any airport authority. Two aspects considered in that kind of measurement: passengers prospective and operators prospective. This thesis tries to combine both in its produced optimisation system. This study was carried out in the Hajj terminal of the King Abdul-Aziz international airport and classified the processing time among the most important measures affecting the users’ observation of the level of service. Produced survey has helped to generate performance measure upon passengers prospective. On the other hand a simulation model of the process flow is utilised to formulate driven data model of the terminal process flow operations. The model built on Arena software and correlation study is made from the multiple “what if” scenarios of the model. Then a linear regression is used to generate a model for each variable. Levenberg–Marquardt (LM) algorithm is used after to carry out better regression model then Neuro-Fuzzy (NF) model found to be more efficient as it is picked and used to generate a best observed prediction. The system is optimised through the generated Neuro-Fuzzy (NF) logic model using both Particle Swarm Optimization (PSO) and Genetic Algorithm (GA). A validation in addition to the testing made in the optimisation system. Analysis shows a great deal of improvement in predictions using fuzzy logic instead of linear regression for all dependent variables. PSO and GA optimisations are carried out and compared to the actual results gathered from the Arena simulation report.

Abstract:

The analysis carried out in this thesis is made from two different points of view, the qualitative and the quantitative, by using the case study of Malmö intermodal terminal. The first analysis is focused on how the intermodal terminals works and which elements of it interact and how, in order to achieve the purpose of the terminal, and how the Intelligent Video Gate is able to affect in any way to this functioning, mainly in a positive way that allows the better functioning of the terminal.From the quantitative point of view what is carried out is a timing and economic analysis of the Malmö Intermodal Terminal, which is based on the information obtained from the qualitative analysis and from the data provided by the terminal operators that allow to make different simulations to compare the effect of the Intelligent Video Gate implementation in this specific terminal, and that could be extended to similar intermodal terminals located in regions with similar labour conditions and that as the European Union have a huge standardized freight system.Finally, what is stated with the provided data, despite not allowing to make the most complex and representative simulation, is that the aim of the Intelligent Video Gate is reached successfully with a great improvement of the efficiency what allows to ensure with quite certainty that the system implementation is recommended in this kind of terminals.

Full text

Abstract:

The objective of this thesis is to study a cycle-to-cycle control approach called Terminal Iterative Learning Control (TILC) and apply it to the process of plastic sheet heating in a thermoforming oven. Until now, adjustments to the oven heater temperature setpoints have been made manually by a human operator following a trial and error approach. This approach causes financial losses, because plastic sheets are wasted during the period of time when the adjustments are made at the beginning of a production run. Worse, the heater setpoints are subject to modification because of variation in the ambient temperature, which has an important impact on the sheet reheat process.
The TILC approach is analyzed by studying the closed-loop system in the discrete cycle domain through the use of the z-transform. The system, which has dynamic behaviour in the time domain, becomes a static linear mapping in the cycle domain. One can then apply on this equivalent system a traditional control approach, while considering that the system output is sampled once at the end of the cycle. On the other hand, from the standpoint of the real system, this control approach can be viewed as cycle-to-cycle control.
The stability and rate of convergence of the TILC algorithm can be analyzed through the location of the closed-loop system poles in the cycle domain. This analysis is relatively easy for a first-order TILC but becomes more complex for a higher-order TILC algorithm. The singular value decomposition (SVD) is used to simplify the convergence analysis while decoupling the system in the cycle domain. The SVD technique can be used to facilitate the design of higher-order TILC algorithms.
Internal Model Control (IMC) is another approach that can make the ILC design easier, because there is only one parameter per filter to adjust. The IMC technique has an interesting feature. In the case where the system is nominal, the closed-loop transfer function of the system is the same as the IMC filter's transfer function. Therefore, the adjustment of the filter parameter allows the designer to select the desired system response.
For industrial processes such as thermoforming ovens, it is important that the systems controlled by TILC algorithms are stable and have good performance. For thermoforming ovens, the terminal sheet temperature response must not be too oscillatory from cycle to cycle, since this may lead to high heater temperature setpoints. In the most serious case, high heater temperatures can cause the sheet to melt and spill on the heating elements at the bottom of the oven.
The performance aspect must not be neglected, since it is important to minimize the number of wasted plastic sheets, particularly at process startup. To avoid such waste of time and material, it is necessary that the TILC algorithm converge as quickly as possible. However, the robustness and performance objectives are conflicting and an acceptable compromise must be achieved. The control engineer must define specifications to describe these two constraints. Tools such as the Hinfinity Mixed-Sensitivity Analysis and mu-Analysis can be used to check the compliance of a given TILC algorithm with the robustness and performance specifications defined before the analysis. One can therefore compare various TILC algorithms quantitatively, through a computed measure obtained with one of the two approaches. These same tools can be used for the design of TILC algorithms, using weighting functions representing the specifications.
Simulation and experimental results obtained on industrial thermoforming machines show the effectiveness of the various approaches in this thesis. Many examples are also presented throughout the chapters.

Abstract:

Abstract Medium access control (MAC) in wireless ad hoc networks has received considerable attention for almost a couple of decades; however, there are still open problems which deserve thorough study in order to facilitate migration to the next generation broadband wireless communication systems. In ad hoc networks, a detected frame collision can be due to the so-called unreachability problem, where the destination station is situated either in the transmission or interference range of an emitting station and is unable to receive connection establishment frames from any of its neighboring stations. Unreachability might also be due to the inability of a radio station to respond to any connection establishment request, though when the unreachable station receives the connection establishment requests, however, it is prohibited from responding to the requests due to being situated in the interference range of the emitting neighbor. To investigate the impact of this problem, we have to be equipped with a proper analytical framework; therefore, as the first part of this thesis, a scalable framework called Parallel Space – Time Markov chain (PSTMC) is proposed, through which a finite load non-saturated ad hoc network can be easily modeled. At the first step, a single-hop ad hoc network is considered and the accuracy of the model is evaluated using extensive numerical results. Subsequently, the proposed framework is further extended to model multi-hop ad hoc networks. Several discussions are also given on how the framework can be deployed for an arbitrary network topology. One of the main key features of the PSTMC model is its remarkable scalability in modeling complex network configurations. In fact, it is shown that multi-hop ad hoc networks have bounded complexity in being modeled by the PSTMC framework due to its spectacular specifications. These features lead us to a powerful tool by which an arbitrary network topology can be studied. In addition, the proposed models clearly facilitate demonstrating the impact of the unreachability problem on the performance of multi-hop networks. The introduced framework shows how the unreachability problem degrades the achieved throughput and channel capacity by the contending radio stations depending on the deployed network topology. In the remainder of the thesis the unreachability problem in mobile ad hoc networks is tackled and a new MAC protocol to enhance the performance of the network is proposed. This MAC scheme is equipped with smart decision-making algorithms as well as adaptive management mechanisms to reduce the impact of the unreachability problem in single channel scenarios. Subsequently, the problem of concurrent radio resource management and contention resolution in multi-channel cognitive ad hoc networks is considered. In particular, a multi-channel technique for traffic distribution among a set of data channels without centralized control, which is enabled by a probabilistic channel selection algorithm as well as a multi-channel binary exponential backoff mechanism, is proposed. It is shown through simulations that the suggested scheme outperforms the existing MAC protocols in multi-channel environments as well as cognitive networks coexisting with primary users. A mathematical model is also introduced to study the performance of the multi-channel MAC protocol in a single-hop non-saturated wireless network.

Abstract:

Les objectifs essentiels des opérateurs ferroviaires sont d'augmenter la sécurité, de réduire les coûts d'exploitation et de maintenance, d'accroître l'attrait et le profit en offrant de nouveaux services aux passagers. Ces objectifs seront atteintsgrâce à une énorme augmentation des échanges de flux de données entre les infrastructures existantes et les technologies présentes utilisées au bord du train. L'efficacité spectrale, l'optimisation des ressources radioélectriques ainsi que l'interopérabilité mais aussi la fiabilité des communications sont des éléments majeurs pour les applications ferroviaires. Ces contraintes ainsi que l'utilisation sporadique des bandes fréquentielles à disposition ont donné le jour à la radio intelligente. Cette dernière se présente comme une technologie émergente qui améliore les performances des systèmes radio existants en intégrant l'intelligence artificielle avec la radio logicielle. Un système radio intelligent est défini par sa capacité à être conscient de son environnement radioélectrique. En effet, afin d'optimiser au maximum les opportunités spectrales qui lui sont offerts, le dispositif radio intelligent doit être capable de transmettresur des bandes laissées libres tout en réalisant un sondage spectral afin de ne pas interférer avec les utilisateurs ayant la priorité sur la bande mais aussi pour détecter d'autres fréquences vacantes. Dans le cadre de cette thèse, nous proposons de nous concentrer sur la problématique de détection de spectre dans un environnement à très forte mobilité. Certaines contraintes sont à prendre en compte, telles que la vitesse. À cela s'ajoute les contraintes de réglementation concernant les critères de détection, telles que la norme IEEE 802.22 WRAN qui stipule que la détection d'un utilisateur prioritaire doit être réalisée à -21dB dans un laps de temps de 2 secondes. L'objectif est donc de concevoir un terminal radio intelligent dans les conditions physiques et réglementaires de transmission dans un environnent ferroviaire
The main objectives of railway operators are to increase safety, reduce operating and maintenance costs, increase attractiveness and profit by offering new services to customers. These objectives will be achieved through a huge increase of data fluxes between existing infrastructure and the technologies currently used on the train. Spectral efficiency, optimization of radio resources, interoperability and reliability of communications are major elements for railway applications. These constraints and the sporadic use of available frequency bands have gave rise to cognitive radio. Cognitive radio is an emerging technology that improves the performance of existing radio systems by integrating artificial intelligence with software radio. A cognitive radio system is defined by its ability to be aware of its radio environment. Indeed, to optimize as much as possible the available spectral opportunities, the cognitive radio device must be able to transmit on free bands while performing a spectrum sensing to not interfere with users having priority on the band and to detect other vacant frequencies. As part of this thesis, we propose to focus on the problem of spectrum detection in a highly mobile environment. Some constraints should be considered, such as speed. Added to this, there are regulatory constraints on detection criteria, such as the IEEE 802.22 WRAN standard, which stipulates that detection of a priority user must be performed at -21 dB within a period of 2 seconds. The objective is therefore to design an intelligent radio terminal in the physical and regulatory conditions of transmission in a railway environment

Abstract:

Un système de transport ferroviaire intelligent est essentiellement caractérisé par son niveau d'autonomie de prise de décision en fonction des conditions qui lui sont extérieurs. Afin de renforcer son intelligence et son autonomie, cette nouvelle génération de systèmes de transport intègre des multiples technologies et standards de communication et de traitement de l'information. L'intégration de ces technologies permet aux opérateurs du transport ferroviaire de réduire les coûts d'exploitation et de maintenance et d'attirer un plus grand nombre de passagers en leur facilitant l'accès ainsi que l'exploitation du transport ferroviaire tout en leur offrant des nouveaux services à bord. Cependant l'utilisation de plusieurs standards de communication ainsi que l'augmentation du trafic (le nombre de passagers et le nombre de véhicules mis en service) déclenchent un besoin sans précédent des ressources radio, notamment au niveau du spectre fréquentiel. En effet, avec la demande croissante des ressources radio, la Radio Intelligente (RI) se présente comme une technologie émergente qui améliore les performances des systèmes radio existants en intégrant l'intelligence artificielle avec la radio logicielle
Any intelligent railway transport system is mainly characterized by its autonomy in making decisions in terms of its external conditions. In order to improve its cognition and autonomy, this new generation of transport systems integrates multiple technologies and standards of communication and information processing. The integration of these technologies allows rail operators to reduce operational and maintenance costs and attracts more passengers by making easier rail transport access and use while offering new services on board. However, using multiple communication standards and increasing traffic (number of passengers and vehicles in service) trigger an unprecedented need for radio resources, particularly frequency spectrum. Indeed, with the growing of radio resources demand, Cognitive Radio (CR) is an emerging technology that improves the performance of existing radio systems by the integration of artificial intelligence and software defined radio (SDR)

Abstract:

The objective of the thesis research is to design such vertical handoff decision algorithms in order for mobile field workers and other mobile users equipped with contemporary multimode mobile devices to communicate seamlessly in the NGWN. In order to tackle this research objective, we used fuzzy logic and fuzzy inference systems to design a suitable handoff initiation algorithm that can handle imprecision and uncertainties in data and process multiple vertical handoff initiation parameters (criteria)
used the fuzzy multiple attributes decision making method and context awareness to design a suitable access network selection function that can handle a tradeoff among many handoff metrics including quality of service requirements (such as network conditions and system performance), mobile terminal conditions, power requirements, application types, user preferences, and a price model
used genetic algorithms and simulated annealing to optimise the access network selection function in order to dynamically select the optimal available access network for handoff
and we focused in particular on an interesting use case: vertical handoff decision between mobile WiMAX and UMTS access networks. The implementation of our handoff decision algorithm will provide a network selection mechanism to help mobile users select the best wireless access network among all available wireless access networks, that is, one that provides always best connected services to users.

Abstract:

La présente Thèse en Intelligence Artificielle est basée sur un tout premier concept nommé “Assistant Conversationnel”, lequel est abordé par le fait qu'un utilisateur quelconque souhaitant joindre un interlocuteur doit pouvoir toujours voir sa requête se réaliser, quelque soit le moyen choisi par le terminal et sans que l'utilisateur ait à choisir lui-même le moyen adéquat. Le problème principal à résoudre se définit en conséquence par la modélisation et la conception d'une interface intelligente, personnalisée et praticable par tous les publics sur les terminaux de communication spécialisables accédant à Internet. Nous avons alors créé et développé de nouveaux procédés “intelligents”, chargés entre-autres de rendre les opérations courantes moins fastidieuses sur des applications de messagerie électronique. Pour cela, nous avons établi un état de l'art des divers terminaux de communication disponibles sur le marché mondial, ainsi qu'une classification taxinomique poussée et une nouvelle hiérarchisation efficace des interfaces intelligentes. Puis, nous avons construit un “Modèle Auto-Adaptable d'Utilisateur” sur un apprentissage comportemental, incrémental et évolutif, finalement implémenté en quatre phases : 1. Analyse, représentation et classification des différentes actions réalisées par l'utilisateur. 2. Proposition régulière à l'utilisateur d'effectuer de manière auto-adaptable les actions apprises. 3. Exécution auto-adaptable de ces différentes séquences d'actions répétitives. 4. Simplification auto-adaptable d'éventuelles “erreurs” ou incohérences de manipulation. Ainsi, cette contribution innovante à l'interfaçage homme-machine avancé a permis d'aboutir à la validation complète d'un logiciel intelligent de communication, tout-à-fait autonome et portable, capable d'assister chaque utilisateur, néophyte comme très expérimenté, dans ses divers travaux quotidiens, et ce de manière conviviale et toujours respectueuse de ses préférences.

Abstract:

The study of applying soft computing techniques, such as evolutionary computation and simulation, to the deployment of intelligent autonomous vehicles (IAVs) in container terminals is the focus of this thesis. IAVs are a new type of intelligent vehicles designed for transportation of containers in container terminals. This thesis for the first time investigates how IAVs can be effectively accommodated in container terminals and how much the performance of container terminals can be improved when IAVs are being used. In an attempt to answer the above research questions, the thesis makes the following contributions: First, the thesis studies the fleet sizing problem in container terminals, an important design problem in container terminals. The contributions include proposing a novel evolutionary algorithm (with superior results to the state-of-the-art CPLEX solver), combining the proposed evolutionary algorithm with Monte Carlo simulation to take into account uncertainties, validating results of the uncertain case with a high fidelity simulation, proposing different robustness measures, comparing different robust solutions and proposing a dynamic sampling technique to improve the performance of the proposed evolutionary algorithm. Second, the thesis studies the impact of IAVs on container terminals’ performance and total cost, which are very important criteria in port equipment. The contributions include developing simulation models using realistic data (it is for the first time that the impact of IAVs on containers terminals is investigated using simulation models) and applying a cost model to the results of the simulation to estimate and compare the total cost of the case study with IAVs against existing trucks. Third, the thesis proposes a new framework for the simulations of container terminals. The contributions include developing a flexible simulation framework, providing a user library for users to create 3D simulation models using drag-and-drop features, and allowing users to easily incorporate their optimisation algorithms into their simulations.

Abstract:

After many years of successful operation in military domains, Unmanned Aerial Systems (UASs) are generating significant interest amongst civilian operators in sectors such as law enforcement, search and rescue, aerial photography and mapping. To maximise the benefits brought by UASs to sectors such as these, a high level of autonomy is desirable to reduce the need for highly skilled operators. Highly autonomous UASs require a high level of situation awareness in order to make appropriate decisions. This is of particular importance to civilian UASs where transparency and equivalence of operation to current manned aircraft is a requirement, particularly in the terminal area immediately surrounding an airfield. This thesis presents an artificial situation awareness system for an autonomous UAS capable of comprehending both the current continuous and discrete states of traffic vehicles. This estimate forms the basis of the projection element of situation awareness, predicting the future states of traffic. Projection is subject to a large degree of uncertainty in both continuous state variables and in the execution of intent information by the pilot. Both of these sources of uncertainty are captured to fully quantify the future positions of traffic. Based upon the projection of future traffic positions a self separation system is designed which allows an UAS to quantify its separation to traffic vehicles up to some future time and manoeuvre appropriately to minimise the potential for conflict. A high fidelity simulation environment has been developed to test the performance of the artificial situation awareness and self separation system. The system has demonstrated good performance under all situations, with an equivalent level of safety to that of a human pilot.

Full text

Abstract:

Numerous decisions in organisations are made by teams, groups or committees. The need for group decision making is brought about by the increased complexity of many decisions which require specialised knowledge in numerous areas usually not possessed by one person. As such there has also been an inherent recognition that different members bring different contributions and that a marshalling of these contributions enhances decision-making. Most research about how to make teams more effective has focused on identifying the task processes that distinguish the most successful teams - that is specifying the need for collaboration, involvement and commitment to goals. The assumption seems to be that, once identified; these processes can simply be imitated by other teams, with similar effects but it is not the case since they do not take the level of the team’s emotional intelligence into consideration. Emotional intelligence should always be considered in a team setting since teamwork is an inherently social activity and as such emotions play an important role in team processes including decision making. Surprisingly the study of the effects of emotions and emotional intelligence in decision making at group level is a relatively new research avenue. Research indicates that emotional intelligence has been the subject of a significant amount of literature for a number of years. However little has been contributed to how the behaviours associated with emotional intelligence may be practically applied to enhance both individual and group decision-making. Druskat and Wolff (2001a and 2001b) proposed a model for emotional intelligence at the group level. According to their model, groups develop a set of behavioural norms called the Group Emotional Competence Norms (GEC norms) which guide the emotional experience in groups. The proposed model by Druskat and Wolff was used to define and measure group emotional intelligence in this study. The aim of the study was to establish whether there was a relationship between team emotional intelligence and team decision making at Transnet Port Terminal’s Ngqura Container Terminal. The findings of the literature study and the empirical study were combined to evaluate whether team emotional intelligence affected team decision making in the chosen population.The literature study suggested that there was a relationship between team emotional intelligence and team decision making. The empirical study confirmed the relationship between group emotional intelligence and group decision making but failed to confirm whether the chosen population consisted of teams.

Addition to the qualitative research is finding the opportunities for improvements inmarshalling yards and proposing emerging technology that could be applied.Master thesis successfully accomplished the task of finding the effects of emerging technologiesin intermodal terminals and marshalling yards. The methodology concluded to be appropriate onefor building task solution. The project is viewed as a breakthrough in this domain but theexpectations for Intelligent Video Gate should stay realistic and proceeded carefully. Eliminationof brake test in marshalling yards is also very optimistic goal but should be followed by appropriatesafety rules and regulations. Simulation of complex systems such as intermodal terminals andmarshalling yards is the task that should be supported by accurate and detailed data, in order tokeep the model and results more realistic.

Abstract:

Cette thèse s’intéresse aux concepts de mobilité et de gestion du spectre dans les réseaux à radio cognitive. Ainsi, nous avons proposé deux approches décentralisées basées sur les systèmes multi-agents (SMA). Nous avons, tout d’abord, intégré des agents au sein des utilisateurs secondaires (n’ayant pas de licence pour l’accès au spectre) et des utilisateurs primaires (disposant d’une licence) et nous avons défini leurs comportements au moment du handover. Notre première solution NESAM propose un mécanisme de négociation entre les agents permettant aux utilisateurs secondaires de se voir allouer une bande de spectre avec un bon rapport prix par durée d’allocation. Nous avons, par ailleurs, proposé une deuxième solution LASMA qui se base sur l’enchère combinée avec de l’apprentissage pour assurer une gestion efficace du spectre ainsi qu’une gestion de la mobilité des utilisateurs à radio cognitive. Nos algorithmes prennent en compte les préférences des utilisateurs, comme la fréquence spectrale, le prix et la durée ainsi que les contraintes de l’environnement spectral telles que les bandes de fréquences disponibles. Nos propositions assurent une exploitation importante des ressources spectrales tout en diminuant le nombre de handovers spectraux. De plus, nos algorithmes offrent un handover spectral transparent et sans interruption lors des déplacements des utilisateurs. Nous avons prouvé également que nos solutions permettent de satisfaire les besoins des utilisateurs et d’améliorer leur utilité
In this thesis, we are interested in mobile cognitive radio networks while ensuring an efficient spectrum sharing and seamless handover at the same time. Hence, we propose two decentralized approaches based on multi-agents systems. We first deployed agents on each primary (licensed) and secondary (unlicensed cognitive radio) users, respectively. Besides, we define agents’ behaviors during the handover process.Our proposal NESAM defines a novel negotiation mechanism between agents to allow secondary users assigning the appropriate spectrum band giving a good price for the use duration. We have also proposed a second solution LASMA using the learning based auctions. Our algorithms take into account users’ requirements such as spectrum frequency, price and duration as well as environment’s constraints such as available resources.Our proposals improve the overall spectrum utilization and minimize the number of spectrum handovers when users move from one network to another one. This proves that our algorithms ensure efficient spectrum allocation and enable seamless handover during user’s mobility. Besides, we proved that our approaches guarantee users’ satisfaction and improve their utility

Abstract:

Le mobile crowdsensing est une nouvelle forme de collecte de données exploitant la foule de terminaux intelligents déjà déployés à travers le monde pour collecter massivement des données environnementales ou comportementales d'une population.Ces dernières années, ce type de collecte de données a suscité l'intérêt d'un grand nombre d'acteurs industriels et académiques dans de nombreux domaines tels que l'étude de la mobilité urbaine, la surveillance de l'environnement, la santé ou l'étude des comportements socioculturels. Cependant, le mobile crowdsensing n'en n'est qu'à ses premiers stades de développement, et de nombreux défis doivent encore être relevés pour pleinement profiter de son potentiel. Ces défis incluent la protection de la vie privée des utilisateurs, les ressources énergétiques limitées des terminaux mobiles, la mise en place de modèles de récompense et de déploiement adaptés pour recruter les utilisateurs les plus à même de collecter les données désirées, ainsi que faire face à l’hétérogénéité des plateformes mobiles disponibles. Dans cette thèse, nous avons cherché à réétudier les architectures des systèmes dédiés au mobile crowdsensing pour adresser les limitations liées au développement, au déploiement et à l'exécution de campagnes de collecte de données. Les différentes contributions proposées sont articulées autour APISENSE, la plate-forme résultante des travaux de cette thèse. APISENSE a été utilisé pour réaliser une campagne de collecte de données déployée auprès d'une centaine d'utilisateurs au sein d'une étude sociologique, et évalué à travers des expériences qui démontrent la validité, l'efficacité et le passage à échelle de notre solution
Mobile crowdsensing is a new form of data collection that takes advantage of millions smart devices already deployed throughout the world to collect massively environmental or behavioral data from a population. Recently, this type of data collection has attracted interest from a large number of industrials and academic players in many areas, such as the study of urban mobility, environmental monitoring, health or the study of sociocultural attitudes. However, mobile crowdsensing is in its early stages of development, and many challenges remain to be addressed to take full advantage of its potential. These challenges include privacy, limited energy resources of devices, development of reward and recruitment models to select appropriates mobile users and dealing with heterogeneity of mobile platforms available. In this thesis, we aim to reconsider the architectural design of current mobile crowdsensing systems to provide a simple and effective way to design, deploy and manage data collection campaigns.The main contributions of this thesis are organize around APISENSE, the resulting platform of this research. APISENSE has been used to carry out a data collection campaign deployed over hundred of users in a sociological study and evaluated through experiments demonstrating the validity, effectiveness and scalability of our solution

Abstract:

When implementing an intelligent transportation system (ITS), stakeholders often overlook the importance of evaluating the system once it is in place. Determining the extent to which the objectives of an investment have been met is important to not only the agency involved, but also to other agencies, so that lessons are learned and mistakes are not repeated in future projects. An effective evaluation allows a transit provider to identify and address areas that could use improvement. Agencies implementing ITS investments often have different goals, needs, and concerns that they hope their project will address and consequently the development of a generic evaluation plan is difficult to develop. While it is recognized that the U.S. Department of Transportation has developed guidelines to aid agencies in evaluating such investments, this research is intended to complement these guidelines by assisting in the evaluation of a site specific ITS investment. It presents an evaluation framework and plan that provides a systematic method for assessing the potential impacts associated with the project by defining objectives, measures, analysis recommendations, and data requirements. The framework developed specifically addresses the ITS investment on the OmniLink local route deviation bus service in Prince William County, Virginia, but could be used as a basis for the evaluation of similar ITS investments. The OmniLink ITS investment includes an automatic vehicle location (AVL) system, mobile data terminals (MDTs), and computer-aided dispatch (CAD) technology.

Full text

Abstract:

Nous assistons actuellement à une évolution considérable des communications mobiles. En l’absence d’accord entre les fournisseurs, changer son point d’attachement au réseau signifie encore casser la session en cours et dépendre de l'application pour récupérer les données perdues. De même, il n'est guère possible pour un utilisateur mobile de contrôler la connectivité de son appareil. L'objectif de cette thèse est de présenter le concept d'une structure technologique innovante pour le contrôle autonome des terminaux multimodes dans les environnements sans fil hétérogènes et non fédérés. Son but est de permettre à un terminal auto-configuré de se connecter et de se déplacer de manière transparente à travers des réseaux indépendants, tout en respectant les choix et préférences de son utilisateur. Le schéma obtenu implique des mécanismes d’abstraction et inter-couches. Il tient compte de contraintes basées sur les systèmes sans fil hétérogènes, les architectures autonomes, et permet l’exécution de services génériques comme le choix du réseau d'accès et la gestion de la connectivité et des sessions. Ce schéma s'applique au terminal mobile, avec des mécanismes dissociés de l'infrastructure réseau. La thèse analyse comment les technologies existantes sont améliorées et combinées avec de nouvelles fonctionnalités pour atteindre cet objectif, et donne une description de l'ensemble du concept et de sa mise en œuvre. Un modèle simulé est utilisé pour évaluer la validité de la structure proposée. Diverses applications à des systèmes réels mettant en œuvre les éléments de cette architecture sont présentées, faisant ressortir la généralité et les principaux avantages du concept
Recent years have witnessed a massive evolution of mobile communications. When no agreement between the network providers exists, changing the attached network still means breaking the session and relying on the application to recover the lost data. In parallel, it is hardly possible for a mobile user to control the connectivity of his terminal. The objective of this thesis is to present the concept of an innovative technological framework for the autonomous control of multimode terminals in heterogeneous and non-federated wireless environments. The aim is to enable a self-configuring terminal to connect and roam seamlessly across independent networks, while respecting its user’s choices and preferences. The target scheme involves abstraction and cross-layer mechanisms. It takes into account constraints based on heterogeneous wireless systems, autonomous architectures and enables generic services such as smart access network selection, connectivity and session management. This scheme applies to the mobile terminal, with mechanisms independent of the network infrastructure. The thesis analyses how existing technologies are enhanced and combined with new features to achieve this objective and gives a description of the overall concept and of its implementation. A simulated model is used to assess the validity of the proposed framework. Diverse applications to real systems that implemented the components of this framework are presented, highlighting the generality and key benefits of the concept

Abstract:

This dissertation examines a bank’s right to unilaterally terminate its contractual relationship with a customer on the basis of reputational risk. The law of contract allows a bank to terminate the bank-customer agreement when the customer is in serious breach of the contract. Over the years, however, a pattern has started to develop by which a bank can unilaterally terminate the bank-customer relationship of high-risk customers based on reputational risk. Banks are reluctant to facilitate the transactions of individuals surrounded by negative publicity, due to fears of how the bank’s investors, customers or counterparts might perceive the bank. Compliance with anti-money laundering (AML) and counter financing of terrorism (CFT) requirements, as set out by both domestic and foreign legislation, results in higher costs for the bank. As such, the profitability of a particular bank-customer relationship may ultimately decline to such an extent that the bank rather decides to make an appropriate business decision by terminating the relationship. Correspondent banking relationships are agreements in terms of which one bank will provide services for another in jurisdictions where the first bank lacks a physical presence. As such, whenever there is a perception that a local bank does not comply with the relevant AML/CFT laws as set out by its domestic legislation, the correspondent bank might decide to terminate its relationship with the local bank, leaving the latter financially excluded from the correspondent banking market. Such a situation would hinder the growth of the South African economy and may also cause a systemic event in the financial industry. Adequate customer due diligence (CDD) measures assist a bank in formulating a clear understanding of the business of its customers. The information obtained through CDD may also assist the bank in determining the reputation of a particular customer. This information can also assist law enforcement in combatting financial crimes. In this regard, it is recommended that a bank should be able to trace the information that was shared with Financial Intelligence Units (FIUs) and law enforcement agencies, so that the bank may reasonably determine the level of reputational risk involved in the relationship.

Cities in the world aim to ensure the mobility of people, through the implementation of efficient Integrated Transportation Systems (ITS). This aims to improve the transport of people, which guarantees that they can be mobilized safely and without delays in the terminals and bus stops of the public transport system. The present article proposes a design of public transport stops aimed at optimizing the waiting time of users when transferring from one bus to another. For the validity of the proposal, the social force model of the Vissim program was used, where the behavior of the users within the bus stops was reflected. The results showed that the waiting times in the calibrated and validated microsimulation model were optimized by approximately 20%, which generates an improvement in the efficiency of the public transport system.

São crescentes os estudos voltados para o desenvolvimento de estratégias de integração e orientação à cadeia de suprimentos. Porém, a especificidade de cada cadeia exige que estudos sejam delineados conforme as características de cada indústria. Este trabalho pretende apresentar um modelo que auxilie na gestão de relacionamentos estratégicos de um terminal de containers, com base em conceitos relacionados a orientação à cadeia de suprimentos. O modelo é originado a partir da extensão do modelo de integração proposto por Lambert et al. (1998) e do modelo de mensuração da integração dos terminais portuários, desenvolvido por Song e Panayides (2007) e Panayides e Song (2008). Nesta proposta, são delimitados 3 diferentes níveis de relacionamento estratégico: monitoramento, mediação e criação de soluções, desenvolvidos a partir da inteligência de mercado que baliza os relacionamentos chave dimensionados pela estratégia do terminal portuário. O presente estudo propõe a aplicação do modelo desenvolvido no Tecon Rio Grande, terminal de containers do Porto de Rio Grande, a partir de duas etapas de pesquisa. A primeira etapa é uma pesquisa quantitativa e serviu para dimensionar a aderência entre a estratégia de orientação à cadeia da organização com relação aos seus relacionamentos chave, identificando possíveis discrepâncias. Nesta primeira etapa é apresentado o mapa de orientação ao relacionamento estratégico, ferramenta fundamental para análise. A segunda etapa trata-se de uma pesquisa qualitativa realizada para identificar os motivos das distorções apontadas pelos usuários chave da cadeia. Os resultados empíricos encontrados nas duas etapas da pesquisa demonstram que o modelo estendido apresentado alcança seu objetivo de identificar a OCS percebida e as variações aos diferentes níveis de relacionamento estrtégico, resultando como ferramenta para gestão de relacionamentos chave de terminais portuários.
There are increasing studies focused on the development of integration strategies and guidance to the supply chain. However, the specificity of each chain requires studies delineated according to the characteristics of each industry. This work intends to present a model that assists in managing strategic relationships of a container terminal, based on concepts related to supply chain orientation. The model is derived from the extent of the integration model proposed by Lambert et al. (1998) and the measurement model of the integration of port terminals, developed by Song and Panayides (2007) and Panayides and Song (2008). At this model are defined three different levels of strategic relationships: monitoring, mediation and creating solutions developed from market intelligence and targeted to key relationships scaled by the strategy of the port terminal. This study proposes to apply the model developed in Tecon Rio Grande, container terminal at the Port of Rio Grande, from two stages of research. The first step is a quantitative research and served to scale the adhesion between the chain orientation strategies of the organization with respect to their key relationships, identifying possible discrepancies. In this first step is also presented the map of the strategic relationship orientation, a fundamental tool for analysis. The second stage it is a qualitative research conducted to identify the reasons for the distortions noted by the chain members. Empirical results demonstrate that the extended model presented can be used as a tool for management of key relationships.

Abstract:

Les terminaux à conteneurs constituent des interfaces inter-modales essentielles pour le réseau de transport mondial. Une manutention efficace des conteneurs dans des terminaux est d'une importance cruciale pour la réduction des coûts de transport et la détermination des plans d'embarquement. Dans ce rapport de thèse, nous proposons principalement une approche de résolution distribuée à travers la description d'un modèle d'optimisation heuristique distribuée baptisé COSAH COntainer Stacking via multi-Agent approach and Heuristic methodqui permet de simuler, résoudre et optimiser l'espace de stockage disponible pour manier les départs et les arrivées des conteneurs dans un port fluvial ou maritime. Autrement dit, COSAH permet de minimiser le nombre total de mouvements parasites tout en respectant des contraintes dynamiques d'espace et de temps. Les performances de COSAH sont ensuite évaluées sur des instances générées aléatoirement, ainsi que des instances extraites de la réalité d'un port maritime tunisien : le port de Radès. En effet, nous avons procédé à une étude expérimentale implémentant et comparant COSAH à la version centralisée associée, toutes deux basées sur un algorithme de recherche non informée et un algorithme de recherche informée. Les résultats obtenus, présentés et illustrés, montrent l'efficacité de COSAH en particulier, et d'une méthode d'optimisation heuristique distribuée alliant les deux concepts : Agent et Heuristique, en général.

Abstract:

Aujourd'hui, la communauté scientifique a l'opportunité de partager des connaissances et d'accéder à de nouvelles informations à travers les documents publiés et stockés dans les bases en ligne du web. Dans ce contexte, la valorisation des données disponibles reste un défi majeur pour permettre aux experts de les réutiliser et les analyser afin de produire de la connaissance du domaine. Pour être valorisées, les données pertinentes doivent être extraites des documents puis structurées. Nos travaux s'inscrivent dans la problématique de la capitalisation des données expérimentales issues des articles scientifiques, sélectionnés dans des bases en ligne, afin de les réutiliser dans des outils d'aide à la décision. Les mesures expérimentales (par exemple, la perméabilité à l'oxygène d'un emballage ou le broyage d'une biomasse) réalisées sur différents objets d'études (par exemple, emballage ou procédé de bioraffinerie) sont représentées sous forme de relations n-aires dans une Ressource Termino-Ontologique (RTO). La RTO est modélisée pour représenter les relations n-aires en associant une partie terminologique et/ou linguistique aux ontologies afin d'établir une distinction claire entre la manifestation linguistique (le terme) et la notion qu'elle dénote (le concept). La thèse a pour objectif de proposer une contribution méthodologique d'extraction automatique ou semi-automatique d'arguments de relations n-aires provenant de documents textuels afin de peupler la RTO avec de nouvelles instances. Les méthodologies proposées exploitent et adaptent conjointement des approches de Traitement automatique de la Langue (TAL) et de fouille de données, le tout s'appuyant sur le support sémantique apporté par la RTO de domaine. De manière précise, nous cherchons, dans un premier temps, à extraire des termes, dénotant les concepts d'unités de mesure, réputés difficiles à identifier du fait de leur forte variation typographique dans les textes. Après la localisation de ces derniers par des méthodes de classification automatique, les variants d'unités sont identifiés en utilisant des mesures d'édition originales. La seconde contribution méthodologique de nos travaux repose sur l'adaptation et la combinaison de méthodes de fouille de données (extraction de motifs et règles séquentiels) et d'analyse syntaxique pour identifier les instances d'arguments de la relation n-aire recherchée
Today, a huge amount of data is made available to the research community through several web-based libraries. Enhancing data collected from scientific documents is a major challenge in order to analyze and reuse efficiently domain knowledge. To be enhanced, data need to be extracted from documents and structured in a common representation using a controlled vocabulary as in ontologies. Our research deals with knowledge engineering issues of experimental data, extracted from scientific articles, in order to reuse them in decision support systems. Experimental data can be represented by n-ary relations which link a studied object (e.g. food packaging, transformation process) with its features (e.g. oxygen permeability in packaging, biomass grinding) and capitalized in an Ontological and Terminological Ressource (OTR). An OTR associates an ontology with a terminological and/or a linguistic part in order to establish a clear distinction between the term and the notion it denotes (the concept). Our work focuses on n-ary relation extraction from scientific documents in order to populate a domain OTR with new instances. Our contributions are based on Natural Language Processing (NLP) together with data mining approaches guided by the domain OTR. More precisely, firstly, we propose to focus on unit of measure extraction which are known to be difficult to identify because of their typographic variations. We propose to rely on automatic classification of texts, using supervised learning methods, to reduce the search space of variants of units, and then, we propose a new similarity measure that identifies them, taking into account their syntactic properties. Secondly, we propose to adapt and combine data mining methods (sequential patterns and rules mining) and syntactic analysis in order to overcome the challenging process of identifying and extracting n-ary relation instances drowned in unstructured texts

Can internet logic scheme be used as a basis to describe public policies evolution on renewable energies production and sharing in urban areas all over the world? The research project analyses the two networks (internet and energetic grids) architectures in actual and future urban areas. This analysis is connected with present and future forecasts energy productions from traditional fuels and from renewable sources. Theoretical analysis is conducted following a double conceptual pathway: - societal networks (Manuel Castells theory) and urban areas evolution (Saskia Sassen and Mike Davis) in order to picture the evolution of cities and towns in modern economies and in developing countries (Chapters 2 and 5); - Material and Energy Flow Analysis (approach by Wuppertal Institute for Climate, Environment and Energy) applied to renewable energy (Chapters 3 and 4) In Chapter 6 case studies are exposed on the deep cleavage between two different worlds: innovative, rich towns on a side and the landfills cities, slums on the other side. In the last part hypothesis and thesis are put together and open questions are explained (Chapter 7).

Abstract:

The document describes the development of a micro-processor based terminal multiplexer to connect four terminals to a standard Hewlett Packard series 1000 mini-computer. The project was required to fulfill the dual roll of both increasing the number of terminals that the HPI000 could support and of reducing the peripheral load on the host CPU. The final product occupied a standard 200mm square HP size interface card and used an 8085 micro-processor and several 8085 family peripheral chips to provide four full duplex serial channels and a high speed data link with the host. A multi-tasking executive was written to control the multiplexer software which was finally implemented as 15 independent tasks occupying 8 kilo-bytes of eprom. The software was written to perform all terminal interaction and editing in order to reduce the host CPU involvement to a single interrupt per record. The resultant interface proved capable of handling an aggregate throughput in excess of 4000 characters per second which was sufficient to cope with all four terminals running at 9600 bits per second, even when all four were transferring in burst mode. The interface also proved to be between five and eighteen times less demanding on the host than the two standard Hewlett Packard interfaces then available. When compared to the low cost HP12531 interface, the multiplexer increased the 9600b/s terminal handling capability of the host from 3 terminals to 52.

In this study, we design and manufacture the lower limb rehabilitation system for patient who needs lower limb rehabilitation, and proposed two treatment modes: (1) Passive motion mode (2) Active motion mode. Passive motion mode applies to patients with early rehabilitation, this mode can bring the patient''s lower limb. The rehabilitation system to maintain or increase the activity of the knee and muscle movement. Active motion mode enable patients to independently move the lower limb. The rehabilitation system give a force feedback to the patient''s lower limb, increasing the patient''s lower limb muscle strength and endurance training. In this study, we using the robust Nonsingular terminal sliding mode control (NTSMC) and Nonsingular fast terminal sliding mode control system based on the state (NTFSMC-s) to achieve trajectory control, but the NTSMC and the NFTSMC-s have discontinuous control effort that make a chattering phenomenon. So, we proposed an Intelligent nonsingular terminal sliding mode control (INTSMC) and an Intelligent nonsingular fast terminal sliding mode control based on state (INFTSMC-s) to estimate the chattering phenomenon, this intelligent controller using the recurrent Chebyshev neural network (RCNN) estimator to estimate the uncertainty of system and disturbances. Active motion mode using the position-base impedance control (PBIC).We using the force sensor give a signal feedback to PBIC, and PBIC give a force to patient''s lower limb to achieve the muscle training. It can modulate the strength training of active-motion mode through adjusting the parameters of PBIC. The PBIC improve the passive-motion mode increase the human safely with the rehabilitation system. In other words, when the force sensor measured a value cross the range of safely value, the rehabilitation system adjusts the trajectory to protect the patient''s low limb immediately. Finally, the simulation and experiment result prove the rehabilitation system have different parameter of patient''s lower limb still capacity and tracking trajectory ability.This study proposed the INTSMC and INFTSMC-s compared with Intellignet sliding mode control (ISMC).The INTSMC and INFTSMC-s have better robustness and tracking trajectory.Active motion mode experiment shows the strength training respond by adjusting the parameters of PBIC.

Abstract:

Philosophiae Doctor - PhD
Seamless mobility is the missing ingredient needed to address the inefficient communication problems faced by the field workforces of service companies that are using field workforce automation solutions to streamline and optimise the operations of their field workforces in an increasingly competitive market place. The key enabling function for achieving seamless mobility and seamless service continuity is seamless handoffs across heterogeneous wireless access networks. A challenging issue in the multi-service next generation wireless network (NGWN) is to design intelligent and optimal vertical handoff decision algorithms, beyond traditional ones that are based on only signal strength, to determine when to perform a handoff and to provide optimal choice of access network technology among all available access networks for users equipped with multimode mobile terminals. The objective of the thesis research is to design such vertical handoff decision algorithms in order for mobile field workers and other mobile users equipped with contemporary multimode mobile devices to communicate seamlessly in the NGWN. In order to tackle this research objective, we used fuzzy logic and fuzzy inference systems to design a suitable handoff initiation algorithm that can handle imprecision and uncertainties in data and process multiple vertical handoff initiation parameters (criteria); used the fuzzy multiple attributes decision making method and context awareness to design a suitable access network selection function that can handle a tradeoff among many handoff metrics including quality of service requirements (such as network conditions and system performance), mobile terminal conditions, power requirements, application types, user preferences, and a price model; used genetic algorithms and simulated annealing to optimise the access network selection function in order to dynamically select the optimal available access network for handoff; and we focused in particular on an interesting use case: vertical handoff decision between mobile WiMAX and UMTS access networks. The implementation of our handoff decision algorithm will provide a network selection mechanism to help mobile users select the best wireless access network among all available wireless access networks, that is, one that provides always best connected services to users

Contemporary cloud-based computing is crucial for the efficient delivery of ICT systems to users, as well as for versatile disaster recovery and business continuity management (BCM) platforms. Based on the need for efficient and fault-tolerant port operations, this study proposes a cloud-based business continuity framework (BCM) for the container terminal operations (CTO) in South Africa. The study examined the impact of ICT systems and services on Container Terminal Operations (CTO); determined Critical Business Functions in operations that must stay operational and analysed the impact of the unavailability of ICT systems and services on critical operations. This empirical study employed both quantitative and qualitative research designs and collecting data through self-constructed and self-administered questionnaires and interviews. Quantitative data was analysed using the IBM Statistical Package of Social Science (SPSS) Version 23 while qualitative data was analysed through thematic analysis of interviews. Results show that to realize effective organizational resilience using BCM, three insights, as underlying mechanisms for assimilating cloud computing in BCM can be inferred: the first is that a digitalized BCM architecture ‘fits’ the cloud computing model. The specific BCM characteristics that befits cloud computing are continuous data processing; continuous data access and delivery; multi-platform data access; always – on ICT Services; and better decision making. Secondly, the cloud computing model is a ‘viable’ model that can contribute to managing complex organizations characterized by business units that are highly differentiated in terms of size, structure, ICT and investment levels. For such complex organizations, viability is visible in terms of how the multi-units can harness collective intelligence (CI) for more effective BCM. Collective intelligence, as a form of universally distributed intelligence that is constantly enhanced, coordinated in real time, and which results in effective mobilization of organizational competence, is a core organizing metaphor for achieving BCM in a complex organization. Lastly, to realize BCM, underpinned by greater digitalization of BCM and harnessing of CI; there is need for rethinking strategy towards adoption of an ‘Intelliport strategy’ or ‘smart’ BCM for ports, currently intertwined with the notion of the 4IR. That the ‘smart’ nature of BCM require the assimilation of 4IR technologies that enable ubiquitous presence and real time information regarding organizational processes. Adopting an ‘Intelliport strategy’ is likely to have two main implications for BCM and practice: the first is linked to the development of a circular economy, in which aggregation of BCM activities can enhance sustainable development of the seaports; and secondly, adoption of a cloud computing model that can result in the enhancement of business growth of the units promote collaborative problem solving and decision making in BCM.

Abstract:

Perçus pendant longtemps comme faisant parti d'un secteur d'activité économique archaïque, les terminaux portuaires de conteneurs constituent un maillon important et méconnue de plusieurs chaînes de transport intermodal. La croissance rapide des volumes de conteneurs manutentionnés dans ces terminaux a pour conséquence d'entraîner une congestion de ceux-ci et, par le fait même, une perturbation des réseaux d'approvisionnements de plusieurs entreprises. En conséquence, l'objectif de ce mémoire peut être divisé en deux temps. Dans un premier temps, la première partie de ce mémoire vise à comprendre le fonctionnement et les problématiques liées à la gestion des terminaux portuaires de conteneurs. Pour ce faire, une revue de la littérature liée à la planification et la gestion des terminaux portuaires de conteneurs est effectuée, ainsi qu'une étude des processus de ces terminaux. Dans un second temps, ce mémoire vise à proposer des pistes de solutions afin de faciliter la transition des conteneurs dans ces terminaux. La principale piste de solution identifiée est l'application des systèmes de transport intelligents aux terminaux portuaires de conteneurs. Dans ce sens, une étude comparative de l'utilisation des systèmes de transport intelligents entre les ports de la côte est canadienne et les ports du reste du monde est présentée. Ensuite, une première version d’un simulateur des opérations d’un terminal portuaire de conteneurs est développée, afin d'être utilisée comme outil d'analyse pour mesurer l'impact d'une introduction plus importante des systèmes de transport intelligents dans les terminaux portuaires de conteneurs. ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : Terminaux portuaires de conteneurs, systèmes de transport intelligents, simulation, transport intermodal, transport de marchandises.
