Gill, Kuldeep S. "Cognitive Radio Connectivity for Railway Transportation Networks." Digital WPI, 2018. https://digitalcommons.wpi.edu/etd-theses/129.
Full textAbstract:
Reliable wireless networks for high speed trains require a significant amount of data communications for enabling safety features such as train collision avoidance and railway management. Cognitive radio integrates heterogeneous wireless networks that will be deployed in order to achieve intelligent communications in future railway systems. One of the primary technical challenges in achieving reliable communications for railways is the handling of high mobility environments involving trains, which includes significant Doppler shifts in the transmission as well as severe fading scenarios that makes it difficult to estimate wireless spectrum utilization. This thesis has two primary contributions: (1) The creation of a Heterogeneous Cooperative Spectrum Sensing (CSS) prototype system, and (2) the derivation of a Long Term Evolution for Railways (LTE-R) system performance analysis. The Heterogeneous CSS prototype system was implemented using Software-Defined Radios (SDRs) possessing different radio configurations. Both soft and hard-data fusion schemes were used in order to compare the signal source detection performance in real-time fading scenarios. For future smart railways, one proposed solution for enabling greater connectivity is to access underutilized spectrum as a secondary user via the dynamic spectrum access (DSA) paradigm. Since it will be challenging to obtain an accurate estimate of incumbent users via a single-sensor system within a real-world fading environment, the proposed cooperative spectrum sensing approach is employed instead since it can mitigate the effects of multipath and shadowing by utilizing the spatial and temporal diversity of a multiple radio network. Regarding the LTE-R contribution of this thesis, the performance analysis of high speed trains (HSTs) in tunnel environments would provide valuable insights with respect to the smart railway systems operating in high mobility scenarios in drastically impaired channels.

Full textAbstract:
Efficient planning of freight transportation requires a comprehensive look at wide range of factors in the operation and man-
agement of any transportation mode to achieve safe, fast, and environmentally suitable movement of goods. In this regard,
a combination of transportation modes offers flexible and environmentally friendly alternatives to transport high volumes
of goods over long distances. In order to reflect the advantages of each transportation mode, it is the challenge to develop
models and algorithms in Transport Management System software packages. This paper discusses the principles of green
logistics required in designing such models and algorithms which truly represent multiple modes and their characteristics.
Thus, this research provides a unique practical contribution to green logistics literature by advancing our understanding of
the multi-objective planning in intermodal freight transportation. Analysis based on a case study from hinterland intermodal
transportation in Europe is therefore intended to make contributions to the literature about the potential benefits from com
bining economic and environmental criteria in transportation planning. An insight derived from the experiments conducted
shows that there is no need to greatly compromise on transportation costs in order to achieve a significant reduction in
carbon-related emissions.

Full textAbstract:
Transportation cost is an important item in total operating cost of an open pit mining operations. In some projects, the transportation cost may reach to 60 % of total operating cost. Turkish Coal Enterprises (TKi) delivers the demanded coal to all cities of Turkey within the context of Prime Ministry Social Solidarity and Aid Fund. The project duration, demanded coal amount whether the coal is needed as packed or unpacked form are determined by local governors. In this study, a model is developed through software, called NAKMAL for the estimation of TKi&rsquos coal transportation cost. Transportation cost model is coded using Visual Studio.NET 2005. This model is designed in modular structure and composed of 19 modules. Excavation and transportation in a mine is an important part of the model. Model considers all the highway, railway and transportation by ship alternatives, as well as the packing operation. This model is being used in evaluation of bids by the decision of TKi&rsquo
s board of executive committee.

Full textAbstract:
The transportation phase of solid waste management is highly critical as it may constitute approximately 60 to 75 percent of the total cost. Therefore, even a small amount of improvement in the collection operation can result in a significant saving in the overall cost. Despite the fact that there exist a considerable amount of studies on Vehicle Routing Problem (VRP), a vast majority of the existing studies are not integrated with GIS and hence they do not consider the path constraints of real road networks for waste collection such as one-way roads and U-Turns. This study involves the development of computer software that optimizes the waste collection routes for solid waste transportation considering the path constraints and road gradients. In this study, two different routing models are proposed. The aim of the first model is to minimize the total distance travelled whereas that of the second model is to minimize the total fuel consumption that depends on the loading conditions of the truck and the road gradient. A comparison is made between these two approaches. It is expected that the two approaches generate routes having different characteristics. The obtained results are satisfactory. The distance optimization model generates routes that are shorter in length whereas the fuel consumption optimization model generates routes that are slightly higher in length but provides waste collection on steeply inclined roads with lower truck load. The resultant routes are demonstrated on a 3D terrain view.

Full textAbstract:
The military has 5 domains of operations: Land, Sea, Air, Space and now Cyber. This 5th Domain is a heterogeneous network (of networks) of Communication and Information Systems (CIS) which were designed and accredited to meet Netcentric capability requirements; to be robust, secure and functional to the organisation’s needs. Those needs have changed. In the globalised economy and across the Battlespace, organisations now need to share information. Keeping our secrets, secret has been the watchwords of Information Security and the accreditation process; whilst sharing them securely across coalition, geo-physically dispersed networks has become the cyber security dilemma. The diversity of Advanced Persistent Threats, the contagion of Cyber Power and insecurity of coalition Interoperability has generated a plethora of vulnerabilities to the Cyber Domain. Necessity (fiscal and time-constraints) has created security gaps in deployed CIS architectures through their interconnections. This federated environment for superior decision making and shared situational awareness requires that Bridging the (new capability) Gaps needs to be more than just improving security (Confidentiality, Integrity and Availability) mechanisms to the technical system interfaces. The solution needs a new approach to creating and understanding a trusted,social-technical CIS environment and how these (sensitive) information assets should be managed, stored and transmitted. Information Assurance (IA) offers a cohesive architecture for coalition system (of systems) interoperability; the identification of strategies, skills and business processes required for effective information operations, management and exploitation. IA provides trusted, risk managed social-technical (Enterprise) infrastructures which are safe, resilient, dependable and secure. This thesis redefines IA architecture and creates models that recognise the integrated, complex issues within technical to organisational interoperability and the assurance that the right information is delivered to the right people at the right time in a trustworthy environment and identifies the need for IA practitioners and a necessary IA education for all Cyber Warriors.

Al-Azzawi, M. "Factors affecting pedestrian walking speeds." Thesis, Edinburgh Napier University, 2004. http://researchrepository.napier.ac.uk/Output/2749.
Full textAbstract:
The movement of pedestrians in the urban environment is vital for sustaining the social and economic relationships essential to the quality of life. To enable and encourage walking, suitable facilities must be available and planning and implementing such facilities requires an understanding of the characteristics of pedestrian movements. This thesis examined the factors which influence walking speeds, related them to current pedestrian modelling techniques and developed a series of new models to improve their estimation. A comprehensive review of current practices and procedures for modelling pedestrian walking speeds was carried out, identifying the factors currently used in existing methodology and highlighted its deficiencies. A significant finding from this study was that the industry-standard Highway Capacity Manual (HCM) methodology as it currently stands is not fully applicable to the types of walking environments that were the subject of this research (on-street walkways in UK shopping and Central Business District areas). It was shown there is a need to provide more holistic relationships which take into account the interactions between the characteristics of pedestrians and their walking environments (both built and natural). A number of additional factors which have a significant affect on walking speeds were identified and a series of new statistical relationships were developed which were also tested and validated against independent data. The predictive performance of the new models was also compared against the leading industry-standard methodology and shown to provide significantly better estimates. Future areas of research were also identified and described. The research thus provided a greater understanding of the dynamics affecting walking speeds, thereby helping to assist transport planners and engineers with the study and design of suitable pedestrian facilities.

Collins, Andrew. "Evaluating reinforcement learning for game theory application learning to price airline seats under competition." Thesis, University of Southampton, 2009. https://eprints.soton.ac.uk/69751/.
Full textAbstract:
Applied Game Theory has been criticised for not being able to model real decision making situations. A game's sensitive nature and the difficultly in determining the utility payoff functions make it hard for a decision maker to rely upon any game theoretic results. Therefore the models tend to be simple due to the complexity of solving them (i.e. finding the equilibrium). In recent years, due to the increases of computing power, different computer modelling techniques have been applied in Game Theory. A major example is Artificial Intelligence methods e.g. Genetic Algorithms, Neural Networks and Reinforcement Learning (RL). These techniques allow the modeller to incorporate Game Theory within their models (or simulation) without necessarily knowing the optimal solution. After a warm up period of repeated episodes is run, the model learns to play the game well (though not necessarily optimally). This is a form of simulation-optimization. The objective of the research is to investigate the practical usage of RL within a simple sequential stochastic airline seat pricing game. Different forms of RL are considered and compared to the optimal policy, which is found using standard dynamic programming techniques. The airline game and RL methods displays various interesting phenomena, which are also discussed. For completeness, convergence proofs for the RL algorithms were constructed.

Today in a modern society the pace is high and the need for flexibility and mobilityis big. Despite the increasing access and great digital solutions for online-meetings,the need for short distance transportation remains. With an increasing number ofeasy-to-use mobile applications, the many offered solutions for personal transporta-tion have in the last few years expanded. Besides the effect of an increasing pressureof road space, the pressure on the transportation solutions has escalated. This is the current situation of the company we came in contact with. Their currenttravel service provides on-demand transportation in small electric, emission free andchauffeur driven vehicles they call pods. As a step of claiming their space in thetransportation sector they are developing their application letting customers planand book a transport. For the ability to test their new booking solution this project took form. With asimulation it would be possible to test the various probabilities of a travel outcome.The aim was to develop a simulation software, simulating the events of multipletravels taking place in the system. With the simulation it would be possible to eval-uate the configuration for the booking feature, analyse how it works with the rest ofthe system and to help the company to predict how the intensity of customers in re-lations to the number of available drivers would affect the outcome of a travel request. The project covered the study of how to interpret the factors, that a transportationdirectly depends on, into events in the system and how to use historical events tocreate probabilities of the simulation outcome. The simulator software was not suc-cessful with simulating multiple rides as intended, but parts of the software could beevaluated in relation to historical events. Statistical models were built using aggre-gated events from the system. When comparing the average result of the statisticalmodels with the historical event count of the system, it resulted in an outcomewithin an acceptable range. This shows that it was possible to use aggregated his-torical events to create probabilities and that these probabilities were reliable.

O sucesso de um projeto depende, em grande parte, da escolha e uso de ferramentas adequadas para o seu desenvolvimento. Como no caso de qualquer outra ferramenta, é de suma importância o conhecimento das características, funções e do desempenho dos programas de computador que se pretende empregar na solução de problemas de qualquer natureza. Tendo por base esta constatação e voltando-se apenas para uma área específica, o objetivo deste trabalho de pesquisa é comparar três software de SIG (Sistemas de Informação Geográfica) aplicados ao planejamento de transportes quanto às suas características funcionais e desempenho. Os software UfosNet, TransCAD e ArcView foram comparados quanto a alguns aspectos descritivos, tais como: tempo de aprendizado e possibilidades de customização, entre outros; características operacionais básicas de SIG; rotinas avançadas de SIG e rotinas específicas de transportes. Para uma análise mais efetiva do potencial dos mesmos como ferramentas de planejamento de transportes foi proposta a solução de um problema envolvendo o cálculo de uma medida de acessibilidade. Através dos resultados encontrados com as diversas avaliações realizadas foi possível concluir que os três sistemas atendem perfeitamente à configuração mínima desejada para um software SIG, mas que apenas o TransCAD e o UfosNet enquadram-se de fato na categoria de SIG-T, uma vez que o ArcView praticamente não fornecia as principais ferramentas necessárias à solução de problemas de transportes específicos. Embora os resultados deste trabalho possam ajudar diretamente aos usuários na escolha do software mais adequado à aplicações específicas na área de transportes, a sua maior contribuição está na metodologia de avaliação em si. Isto se deve à evolução extremamente rápida dos programas de computador, que torna qualquer resultado de uma análise comparativa efêmero e não conclusivo. Neste sentido, a metodologia de avaliação pode ser útil tanto para grandes empresas que desejam aplicar soluções de geoprocessamento, como para usuários individuais ou autônomos, pois em ambos os casos pode contribuir para um máximo aproveitamento do SIG como uma ferramenta auxiliar na solução de problemas de transportes.The success degree of any project is largely determined by the use of adequate tools to its development. Like any other tool, it is of utmost importance the knowledge of characteristics, functions and performance of the computer program one intends to use to solve any particular problem. Bearing it in mind and turning towards an specific area, the objective of this research work is to compare three GIS (Geographic Information Systems) software applied to transportation planning, concerning its functional and performance characteristics. The computer packages UfosNet, TransCAD, and ArcView were compared regarding some descriptive aspects, such as: learning time and customization possibilities, among others; basic GIS operating characteristics, advanced GIS routines and transportation routines. In order to conduct a more effective analysis of their potential as a transportation planning tool they were all applied for finding a solution of a problem involving the calculation of an accessibility measure. The results found suggest that all three systems comply with the minimum configuration desired for a GIS software. However, only TransCAD and UfosNet fit in the GIS-T category, since ArcView did not supply the main necessary tools to solve the specific transportation problems proposed. Although the results of this work may directly help users in their choice of more adequate software, its biggest contribution lies in the evaluation methodology itself. It is so due to the extremely fast evolution of computer programs that makes any result of a comparative analysis ephemeral and non-conclusive. In this sense, the evaluation methodology might be useful to big companies seeking GIS solutions as well as to individual users, since in both cases it can contribute to the maximum use of GIS as a supporting tool for solving transportation problems.

Barbosa, Manuel Romano dos Santos Pinto. "Traffic management and control of automated guided vehicles using artificial neural networks." Thesis, University of Warwick, 1997. http://wrap.warwick.ac.uk/4200/.
Full textAbstract:
An industrial traffic management and control system based on Automated Guided Vehicles faces several combined problems. Decisions must be made concerning which vehicles will respond, or are allocated to each of the transport orders. Once a vehicle is allocated a transport order, a route has to be selected that allows it to reach its target location. In order for the vehicle to move efficiently along the selected route it must be provided with the means to recognise and adapt to the changing characteristics of the path it must follow. When several vehicles are involved these decisions are interrelated and must take into account the coordination of the movements of the vehicles in order to avoid collisions and maximise the performance of the transport system. This research concentrates on the problem of routing the vehicles that have already been assigned destinations associated with transport orders. In nearly all existing AGV systems this problem is simplified by considering there to be a fixed route between source and destination workstations. However if the system is to be used more efficiently, and particularly if it must support the requirements of modern manufacturing strategies, such as Justin- Time and Flexible Manufacturing Systems, of moving very small batches more frequently, then there is a need for a system capable of dealing with the increased complexity of the routing problem. The consideration of alternative paths between any two workstations together with the possibility of other vehicles blocking routes while waiting at a particular location, increases enormously the number of alternatives that must be considered in order to identify the routes for each vehicle leading to an optimum solution. Current methods used to solve this type of problem do not provide satisfactory solutions for all cases, which leaves scope for improvement. The approach proposed in this work takes advantage of the use of Backpropagation Artificial Neural Networks to develop a solution for the routing problem. A novel aspect of the approach implemented is the use of a solution derived for routing a single vehicle in a physical layout when some pieces of track are set as unavailable, as the basis for the solution when several vehicles are involved. Another original aspect is the method developed to deal with the problem of selecting a route between two locations based on an analysis of the conditions of the traffic system, when each movement decision has to be made. This lead to the implementation of a step-by-step search of the available routes for each vehicle. Two distinct phases can be identified in the approach proposed. First the design of a solution based on an ANN to solve the single vehicle case, and subsequently the development and testing of a solution for a multi-vehicle case. To test and implement these phases a specific layout was selected, and an algorithm was implemented to generate the data required for the design of the ANN solution. During the development of alternative solutions it was found that the addition of simple rules provided a useful means to overcome some of the limitations of the ANN solution, and a "hybrid" solution was originated. Numerous computer simulations were performed to test the solutions developed against alternatives based on the best published heuristic rules. The results showed that while it was not possible to generate a globally optimal solution, near optimal solutions could be obtained and the best hybrid solution was marginally better than the best of the currently available heuristic rules.

Full textAbstract:
Bicycle transportation has become a central priority of urban areas invested in improving sustainability, livability, and public health outcomes. Transportation agencies are striving to increase the comfort of their bicycle networks to improve the experience of existing cyclists and to attract new cyclists. The Oregon Department of Transportation sponsored the development of ORcycle, a smartphone application designed to collect cyclist travel, comfort, and safety information throughout Oregon. The sample resulting from the initial deployment of the application between November 2014 and March 2015 is described and analyzed within this thesis. 616 bicycle trips from 148 unique users were geo-matched to the Portland metropolitan area bicycle and street network, and the self-reported comfort level of these trips was modeled as a function of user supplied survey responses, temporal characteristics, bicycle facility/street typology, traffic volume, traffic speed, topography, and weather. Cumulative logistic regression models were utilized to quantify how these variables were related to route comfort level within separate variable groups, and then the variables were used in a pooled regression model specified by backwards stepwise selection.
The results of these analyses indicated that many of the supplied predictors had significant relationships with route comfort. In particular, bicycle miles traveled on facilities with higher traffic volumes, higher posted speeds, steep grades, and less separation between bicycles and motor vehicles coincided with lower cyclist comfort ratings. User supplied survey responses were also significant, and had a greater overall model variance contribution than objectively measured facility variables. These results align with literature that indicates that built environment variables are important in predicting bicyclist comfort, but user variables may be more important in terms of the variance accounted for. This research outlines unique analysis methods by which future researchers and transportation planners may explore crowdsourced data, and presents the first exploration of bicyclist comfort perception data crowdsourced using a smartphone application.

Osgood, Thomas J. "Semantic labelling of road scenes using supervised and unsupervised machine learning with lidar-stereo sensor fusion." Thesis, University of Warwick, 2013. http://wrap.warwick.ac.uk/60439/.
Full textAbstract:
At the highest level the aim of this thesis is to review and develop reliable and efficient algorithms for classifying road scenery primarily using vision based technology mounted on vehicles. The purpose of this technology is to enhance vehicle safety systems in order to prevent accidents which cause injuries to drivers and pedestrians. This thesis uses LIDAR–stereo sensor fusion to analyse the scene in the path of the vehicle and apply semantic labels to the different content types within the images. It details every step of the process from raw sensor data to automatically labelled images. At each stage of the process currently used methods are investigated and evaluated. In cases where existingmethods do not produce satisfactory results improvedmethods have been suggested. In particular, this thesis presents a novel, automated,method for aligning LIDAR data to the stereo camera frame without the need for specialised alignment grids. For image segmentation a hybrid approach is presented, combining the strengths of both edge detection and mean-shift segmentation. For texture analysis the presented method uses GLCM metrics which allows texture information to be captured and summarised using only four feature descriptors compared to the 100’s produced by SURF descriptors. In addition to texture descriptors, the ìD information provided by the stereo system is also exploited. The segmented point cloud is used to determine orientation and curvature using polynomial surface fitting, a technique not yet applied to this application. Regarding classification methods a comprehensive study was carried out comparing the performance of the SVM and neural network algorithms for this particular application. The outcome shows that for this particular set of learning features the SVM classifiers offer slightly better performance in the context of image and depth based classification which was not made clear in existing literature. Finally a novel method of making unsupervised classifications is presented. Segments are automatically grouped into sub-classes which can then be mapped to more expressive super-classes as needed. Although the method in its current state does not yet match the performance of supervised methods it does produce usable classification results without the need for any training data. In addition, the method can be used to automatically sub-class classes with significant inter-class variation into more specialised groups prior to being used as training targets in a supervised method.

Resumo: O processo de geração e de disposição final de resíduos em todas as suas formas tem sido responsável por problemas econômicos, ecológicos e de saúde pública, dentre os mais relevantes. Para que o gerenciamento dos resíduos perigosos seja realizado de maneira amigável ao meio ambiente, uma série de medidas técnicas e administrativas deve ser implementada, envolvendo desde a prevenção e o controle efetivo da geração do resíduo até a sua disposição final. O setor nuclear tem uma longa e bem sucedida experiência em todas as atividades administrativas e operacionais envolvidas no manuseio, tratamento, condicionamento, transporte, armazenamento e disposição final de rejeitos radioativos. Estes conhecimentos adquiridos podem ser utilizados no desenvolvimento de uma metodologia unificada para o gerenciamento de resíduos perigosos, radioativos e não radioativos, aqui tratados como ¿rejeitos¿, em atendimento às exigências cada vez mais restritivas impostas pelo mercado, consumidores, órgãos reguladores e grupos ambientais. O principal objetivo deste trabalho é desenvolver e implementar uma metodologia unificada, dirigida em particular a pequenos geradores, instituições que geram pequenas quantidades de rejeitos de diferentes composições, procurando integrar as diversas atividades envolvidas no gerenciamento. A metodologia foi desenvolvida para servir como uma ferramenta facilitadora dessas atividades, devendo ser aplicada por usuário especializado. Para simplificar e agilizar a sua aplicação, foi desenvolvido um programa de computador denominado SUGERE - Sistema Unificado de GEstão de Resíduos, no sistema operacional Windows® em ambiente Borland Delphi®. A indústria nuclear é utilizada como referência para o desenvolvimento do trabalho, tendo sido implementada, disponibilizada e exemplificada a aplicação de muitos procedimentos, normas e padrões desta área
Abstract: The process of generation and disposal of wastes has been responsible for many economical, ecological and public health problems, although the importance of its safe management for the protection of human health and the environment has long been recognized. In order to manage the hazardous wastes in an environmentally-friendly manner, many technical and administrative procedures should be implemented, from prevention and control of waste generation to a final disposal. The nuclear area personnel have a long and successful experience in all administrative and operational activities involved in the handling, treatment, conditioning, transport, storage and disposal of radioactive waste. Thus, this knowledge can be considered in the development of a unified methodology for managing all kinds of hazardous waste. The main purpose of the present work is to develop and implement a methodology, primarily to institutions that generate small amounts of waste of different compositions, on the predisposal activities management. This methodology was developed to provide a facilitator tool that should be applied by expert users. To simplify and automatize its application, a software, named SUGERE - a unified system for waste management, was developed in a Windows? environment using a Borland Delphi? package. The nuclear industry was used as a reference for developing this work and many examples of this area standards and procedures are implemented.

Full textAbstract:
The automotive domain is changing. On the way to more convenient, safe, and efficient vehicles, the role of electronic controllers and particularly software has increased significantly for many years, and vehicles have become software-intensive systems. Furthermore, vehicles are connected to the Internet to enable Advanced Driver Assistance Systems and enhanced In-Vehicle Infotainment functionalities. This widens the automotive software and system landscape beyond the physical vehicle boundaries to presently include as well external backend servers in the cloud. Moreover, the connectivity facilitates new kinds of distributed functionalities, making the vehicle a part of an Intelligent Transportation System (ITS) and thus an important example for a future Internet of Things (IoT). Manufacturers, however, are confronted with the challenging task of integrating these ever-increasing range of functionalities with heterogeneous or even contradictory requirements into a homogenous overall system. This requires new software platforms and architectural approaches. In this regard, the connectivity to fixed side backend systems not only introduces additional challenges, but also enables new approaches for addressing them. The vehicle-to-backend approaches currently emerging are dominated by proprietary solutions, which is in clear contradiction to the requirements of ITS scenarios which call for interoperability within the broad scope of vehicles and manufacturers. Therefore, this research aims at the development and propagation of a new concept of a universal distributed Automotive Service Delivery Platform (ASDP), as enabler for future automotive functionalities, not limited to ITS applications. Since Machine-to-Machine communication (M2M) is considered as a primary building block for the IoT, emergent standards such as the oneM2M service platform are selected as the initial architectural hypothesis for the realisation of an ASDP. Accordingly, this project describes a oneM2M-based ASDP as a reference configuration of the oneM2M service platform for automotive environments. In the research, the general applicability of the oneM2M service platform for the proposed ASDP is shown. However, the research also identifies shortcomings of the current oneM2M platform with respect to the capabilities needed for efficient communication and data exchange policies. It is pointed out that, for example, distributed traffic efficiency or vehicle maintenance functionalities are not efficiently treated by the standard. This may also have negative privacy impacts. Following this analysis, this research proposes novel enhancements to the oneM2M service platform, such as application-data-dependent criteria for data exchange and policy aggregation. The feasibility and advancements of the newly proposed approach are evaluated by means of proof-of-concept implementation and experiments with selected automotive scenarios. The results show the benefits of the proposed enhancements for a oneM2M-based ASDP, without neglecting to indicate their advantages for other domains of the oneM2M landscape where they could be applied as well.

"Modelo multiagentes baseado em um protocolo de leilões simultâneos para aplicação no problema de planejamento de transferências de produtos no segmento downstream do sistema logístico brasileiro de petróleo." Universidade Tecnológica Federal do Paraná, 2014. http://repositorio.utfpr.edu.br/jspui/handle/1/822.
Full textAbstract:
CAPESO segmento downstream da cadeia de suprimentos da indústria brasileira de petróleo é composta por bases de produção (e.g. refinarias), armazenamento (e.g. terminais) e consumo (e.g. mercados consumidores) e modais de transportes (e.g. oleodutos, navios, caminhões e trens). O planejamento da transferência de derivados de petróleo nesta rede multimodal é um problema complexo e atualmente é realizado para um horizonte de três meses com base na experiência de profissionais e sem auxílio de um sistema computacional de apoio à decisão. Basicamente, o problema pode ser visto como uma negociação para alocação de recursos disponíveis (tais como derivados de petróleo, tanques e modais de transporte) pelas diferentes bases envolvidas que necessitam enviar ou receber derivados de petróleo. Na literatura, alguns problemas semelhantes, porém mais voltados para o planejamento de redes formadas por um único tipo de modal de transporte, têm sido tratados por diferentes abordagens, com predominância da programação matemática. Estes trabalhos ilustram a difícil tarefa de modelar grandes problemas por meio desta abordagem. Geralmente, tais trabalhos consideram apenas um curto horizonte de planejamento ou apenas uma parte do problema original, tal como uma parte da rede petrolífera brasileira, gerando limitações importantes para os modelos desenvolvidos. Devido às características do problema em estudo, o qual envolve toda a rede de transporte e apresenta perfil de negociação entre as diferentes entidades envolvidas, surge o interesse da utilização do paradigma de sistemas multiagente. O paradigma de agentes tem sido aplicado a problemas de diferentes contextos, particularmente em problemas de gerenciamento de cadeias de suprimentos devido à sua correspondência natural com a realidade e, em geral, em problemas que envolvem a competição por recursos por meio de mecanismos de negociação com base em leilões. Este trabalho apresenta um novo protocolo de negociação baseado em leilões e aplicação deste protocolo em forma de um modelo multiagente na resolução do problema de planejamento em questão. Os agentes que formam a solução representam principalmente os locais de produção, armazenamento, consumo e os modais de transporte na rede petrolífera brasileira. O objetivo destes agentes é manter um nível de estoque diário factível de cada produto em cada local por meio de transferências de produtos pela rede petrolífera brasileira com preferível redução do custo de transporte. Por fim, este trabalho apresenta a satisfação destes objetivos por meio de experimentos em cenários fictícios e reais da rede brasileira de petróleo.
The Brazilian oil supply chain is composed by oil refineries, consumer markets, terminals for intermediary storage and several transportation modals, such as pipelines, ships, trucks and trains. The transportation planning of oil products in this multimodal network is a complex problem that is currently performed manually based on expertise, for a period of three months, due to the lack of a software system to cover the problem complexity. Such problem involves the negotiation of available resources such as oil products, tanks and transportation modals between different sources and consumption points. Similar problems, but more directed to the planning of single modes of transportation, have been treated by different approaches, mainly mathematical programming. Such works illustrate the difficult task of modeling large problems with this mechanism. Generally, they consider a short horizon planning or only part of the original problem, such as a part of the network, rendering important limitations to the models developed. Due to the characteristics of the problem in study where the full network needs to be considered and there exists negotiation amongst the different entities involved, the usage of multi-agent models seems to be worth to explore. Such models have been applied in different contexts such as to supply chain problems due its natural correspondence with the reality. Furthermore, in problems involving competition for resources, multi-agents negotiation mechanisms based on auctions are commonly applied. Thus, this thesis presents one auction-based solution formed by the cooperation among agents for them to achieve their goals. The agents involved in the auctions represent mainly the production, storage and consumption locations. Their goal is to maintain a daily suitable inventory level for each product by means of transportation through the multimodal network at a low transport cost. Finally, this paper presents the satisfaction of these objectives through experiments on real and fictional scenarios of Brazilian oil network.

Full textAbstract:
La complexité des systèmes de transport rend difficile la maîtrise de leur conception dans la mesure où ils intègrent des composantes technologiques, mais aussi sociologiques et politiques. Il est alors opportun de proposer un système destiné à aider à la définition d’une politique de transport urbain. L’objectif principal de notre recherche est de proposer l’architecture logicielle d’un outil de simulation visant à aider un décideur, chargé de la régulation d’un système de transport urbain, pour son travail d’analyse et d’évaluation des impacts des stratégies de régulation. Notre système est basé sur un simulateur à base d’agents intégrant des informations géographiques et temporelles pour évaluer des scénarii de régulation. En termes d’architecture du système, nous avons adopté une approche «système de systèmes», principalement structurée par couches, afin de modéliser les principaux éléments du système. La validation de notre outil de simulation a pu être effectuée à partir d’une étude de cas de taille et de complexité significative puisque nous disposons des enquêtes de déplacement, de recensement, et des mesures de trafic. Nous avons réalisé un prototype pour les déplacements des usagers dans la ville de La Rochelle à partir des données statistiques de l’INSEE et de la BD TOPO 2 de l’IGN en utilisant la plate-forme de simulation GAMATransport systems are becoming more complex and must incorporate not only technological components, but also sociological and political ones. In particular, they should be easy to adapt in order to incorporate the goals set by decision makers, such as the integration of sustainable development settings. The main objective of our research is to propose software architecture of a simulation tool to help a decision maker, responsible for the regulation of an urban transportation system to analyze and evaluate the impacts of regulatory strategies. We propose a system to assist in the definition of an urban transportation policy. Our system is based on an agent-based simulation integrating spatial and temporal information to evaluate regulatory scenarios. In terms of system architecture, we adopted a “system of systems” approach, mainly structured in layers, in order to model the main elements of the system. The validation of our simulation tool could be done from a case study of significant size and complexity because we have travel surveys, census, and traffic measurements. We made a prototype for the movement of people in the city of La Rochelle from statistical data of INSEE and the BD TOPO 2 of IGN using the GAMA platform

Transportation has always played an important role in influencing the development of
societies. It is necessary to understand the current transportation systems to develop feasible
future plans.
The transportation situation in developing countries is becoming critical because of the
negative influence of transportation on the environment. While most of the focus of previous
studies was mega-cities, cities with populations of less than a million, have also experienced
the negative impacts.
This study is conducted as a case study to analyze the current transportation system and travel
patterns in the middle-sized city of Piura, Peru. The primary purposes are (1) to better
understand the transportation activities and travel behaviour of the city more, and (2) to
construct a prototype transportation planning model for the city.
The study has achieved those primary purposes. The level of understanding of the
transportation activities and travel characteristics of the city are certainly increased through
the analysis of trip purpose, time and modes, for example. The successful prototype
transportation modeling shows the applicability of a standard transportation system modeling
tool. This study is a benchmark study for the city.
While this study has successfully demonstrated the use of planning techniques, there are
difficulties which should be addressed and overcome. Further research is necessary in order
to better understand the transportation system and develop a more effective transportation
model.

Planning for transportation within northern Canadian communities presents
unique challenges, but new research tools offer opportunities for testing potentially
innovative solutions that might help improve mobility within these communities. In
particular, problem solving has been enriched in recent years by using the spatial
modeling methods offered by Geographical Information Systems (GIS). This thesis first
reviews various GIS methods before applying one method – the ‘Route Utility Theory’ –
to a newly-developed set of metrics for determining the cost of alternate modes of intracommunity
transportation. This set of metrics is applied to a data set that represents the
trips or journeys made by non-car users in Iqaluit, the capital city of Nunavut Territory.
GIS data on roads, walking trails, land contours, and public and residential
neighbourhoods are analyzed. The results facilitate comparisons between road options
and trail options for improving the movement of people within Iqaluit. Five bus routes
were then custom designed and compared using the study’s metrics. The study found
that increasing bus and trail options within Iqaluit would provide more efficient options
for non-car users. It is argued that the study’s metrics can be adapted for application in
other northern communities, and possibly in other isolated and rural communities in
different world situations.Graduate

The main aim of transport stakeholders has always been to transport freight efficiently, as this efficiency contributes to the growth and success of their business. A country like Namibia is no different as the efficiency of transport lies in the effective utilisation of carrier capacity in any direction. Due to the various types of freight, transport operators rarely have the capacity to cover all freight movement requests. This research put the empty runs experienced by most of the Namibian transporters at 33%. Empty runs could however be reduced through collaboration and sharing of capacity among transport stakeholders.
Multi-agent systems (MAS) are various individual computer agents that are configured independently to interact with other agents to achieve one goal. These systems have been explored as an approach to achieve collaboration among transporter stakeholders. Taking into consideration the characteristics and requirements of MAS, this research was able to conduct a feasibility of its implementation within Namibia. Concluding with an evaluation of available Multi-agent based systems that could achieve collaboration and reduce empty runs in the Namibian transport environment.Information Science

Learning programs using simulation technologies are not just a suitable form of replacement for classical textbooks. They are a brand new teaching aid using Jan Amos Komenský's old motto "Schola Ludus" is a school game. The combination of a virtual and realistic environment with simulation models enables students to visually explore the possibilities of dealing with an emergency situation. One of the projects implemented by the non-governmental nonprofit organization Center for Safe State Project Software Applications 3D simulator. The motivation for choosing the topic of my thesis is that I have been working as the head of a laboratory in a chemical plant for several years. One of the main activities is the transport of dangerous chemicals by road and rail, or operations related to packaging, loading, filling and unloading of such chemicals. My daily activity is responsible for preventing the occurrence of undesirable risks with regard to the protection of persons, property and the environment. To create a textbook for 3D simulator and consequently to use it in the framework of teaching was the main aim of this work. It is important to realize that dangerous substances can escape almost at any moment, so it is necessary to create conditions for the prevention of these events. The success of this area is mainly a good, systematic and coordinated preparation of decisive activities. The diploma thesis is divided into two parts. The theoretical part briefly summarizes the basic knowledge and information about the given issue. There are described the most commonly used software tools and their use for teaching. I deal with the model solution of the accident in the transport of dangerous substances in the practical part, the scenario being created includes a description of the activities that are involved in the management and solution of an emergency. This knowledge was subsequently used to create learning text.

The intention of this thesis is to develop a prototype interface that enables an operator to control a bi-wheeled industrial hovercraft that will work within a fusion power plant if the automation system fails. This fusion power plant is part of the ITER project a conjoint effort of various industrialized countries to develop cleaner sources of energy.
The development of the interface prototype will be based on situation awareness concepts, which provide a means to understand how human operators perceive the world around, then process that information and make decisions based on the knowledge that they already have and the projected knowledge of the reactions that will occur in the world in response to the actions the operator makes. Two major situation awareness methods will be used, GDTA as a means to discover the requirements the interface needs to solve, and SAGAT to conduct the evaluation on the three interfaces. This technique can isolate the differences an operator has in situation awareness when presented with relevant information given by each of the three interfaces that were built for this thesis. Where the first interface presents the information within the operator’s focal point of view in a pictorial style, the second interface shows the same information within the same point of view has the first interface but only shows it in a textual manner. While the third interface shows the relevant information in the operator’s peripheral field of view. Also SAGAT can provide insight on the question to know if providing the operator with feed-forward information about the stoppage distances of the bi-wheeled industrial hovercraft has any effect on the operator’s decision making.Universidade da Madeira

Indiana University-Purdue University Indianapolis (IUPUI)The Pedestrian Automatic Emergency Braking System (PAEB) can utilize on-board sensors to detect pedestrians and take safety related actions. However, PAEB system only benefits the individual vehicle and the pedestrians detected by its PAEB. Additionally, due to the range limitations of PAEB sensors and speed limitations of sensory data processing, PAEB system often cannot detect or do not have sufficient time to respond to a potential crash with pedestrians. For further improving pedestrian safety, we proposed the idea for integrating the complimentary capabilities of V2V and PAEB (V2V-PAEB), which allows the vehicles to share the information of pedestrians detected by PAEB system in the V2V network. So a V2V-PAEB enabled vehicle uses not only its on-board sensors of the PAEB system, but also the received V2V messages from other vehicles to detect potential collisions with pedestrians and make better safety related decisions. In this thesis, we discussed the architecture and the information processing stages of the V2V-PAEB system. In addition, a comprehensive Matlab/Simulink based simulation model of the V2V-PAEB system is also developed in PreScan simulation environment. The simulation result shows that this simulation model works properly and the V2V-PAEB system can improve pedestrian safety significantly.
