L’objet de cette thèse est de définir et d’identifier les effets des politiques de différenciation tarifaire sur l’usage et l’organisation d’un réseau de transport de voyageur urbain ou interurbain. Par différenciation tarifaire, on entend la capacité à faire payer à l’utilisateur un service à des prix différents, en tenant compte de plusieurs critères que nous définirons : l’usage, la distance parcourue…. La tarification différenciée est également appelée discrimination tarifaire de deuxième niveau dans les pays anglo-saxons. La politique tarifaire d’un réseau de transport public répond à trois objectifs qui sont souvent contradictoires. Le premier est la collecte de la recette et la couverture des coûts, le second est l’orientation des usages sans détériorer la fréquentation. Enfin le troisième présente la politique tarifaire comme un instrument possible de politique urbaine. Quels sont les éléments d’une politique tarifaire qui peuvent avoir une influence sur le comportement des utilisateurs en termes de déplacement sur un territoire ? Est-ce qu’un tarif multimodal va générer plus de déplacements combinés, un meilleur taux de fréquentation ? Peut-on observer des changements de comportements suite à l’introduction de tarifications spécifiques comme les tarifs heures de pointe/heure creuses ? Les moyens de paiement comme les facilités d’accès au service font également partie de la stratégie tarifaire : les cartes prépayées, le post paiement, les cartes à valeur permettant de débiter le prix des trajets en fonction des pratiques sont autant de supports permettant l’accès à des bouquets de services. Des tarifications parfois extrêmement sophistiquées ne sont pas perçues comme telles par les utilisateurs. La première partie a pour objectif de définir les enjeux autour de l’élaboration du tarif et de la différenciation tarifaire. Les mécanismes et les composantes de la différenciation tarifaire seront définis et les travaux déjà réalisés sur les relations entre tarification et usage d’un service seront passés en revue de manière à dégager un état des lieux des pratiques tarifaires existantes et hiérarchiser celles pouvant avoir un impact direct sur l’usage spatial du réseau. Dans une deuxième partie, l’étude portera sur la dimension spatiale du tarif à travers l’étude des relations entre les différentes tarifications à la distance et la morphologie spatiale des territoires considérés. L’efficacité des pratiques tarifaires eu égard aux politiques de planification urbaine sera évaluée à partir d’exemples de villes ayant des formes urbaines de type mono-centrique, polycentrique ou composite. La relation entre tarification et morphologie urbaine sera confirmée. L’objet de la troisième partie est de simuler le comportement des utilisateurs lors de modifications tarifaires à partir des données de fréquentation disponibles grâce aux validations billettiques. Dans un premier temps à partir des données de validations des réseaux urbains et interurbains de Belfort ainsi que du département de l’Oise et de la Drôme, nous montrerons qu’il est possible de faire des analyses ciblées. Puis, à partir des données réelles collectées sur le réseau d’Ile de France, et en se projetant à l’introduction d’une ligne structurante nouvelle comme la ligne 15 du Grand Paris, nous chercherons à simuler l’impact d’une tarification différenciée sur la fréquentation globale des deux réseaux. En utilisant un algorithme de répartition des flux selon un modèle de répartition entre deux itinéraires concurrents, Il s’agira d’explorer une méthode de construction d’une grille tarifaire qui fixerait des niveaux de recette globale tout en orientant les usages sur des objectifs définis : niveau d’utilisation de la nouvelle ligne, tranche horaire, courts et long trajets.... / The purpose of this thesis is to define and identify the effects of price discrimination policies on the use and organization of urban public transports. Price discrimination is the possibility to price a service with different level of tariff. At first, we will define the issues around public transport fares, whose complexity is now mitigated by existing smart cards and other payment tools. Then, the spatial dimension of the fare will be given special attention through the study of the relationships between fee structure and spatial morphology of 10 cities around the world. The relationships between urban morphology and pricing will be confirmed. Knowing that usage of public transport are diverse, it is essential to have a good knowledge of users habits. Smard Card data reconstruction provides geographical and statistical information that can be re used for urban planning and for pricing policy. How ?Grand Paris orbital line 15, will be launched in 2020. It is an example of introducing a new metro line inducing significant time savings for commuters. Passengers will be given a real alternative between their usual route and the new one. The new route can offer several advantages: gain of time spent during the trip, gain in terms of number of transfers, comfort gain, security gain, price advantages. This could be an opportunity for an agency to review its fare policy. Our model is based on existing travel flows derived from the itinerary reconstruction from Navigo Smart Card pass. It establishes the principles of a fare grid based on travelers’ preferences and current travel patterns. For this research, we used data from public transport pass users in the Paris’ Metropolitan area, for one month. Finally, we show that price discrimination is related to "mobility" and not to “public transport”. If we consider the mobility needs of the user, pricing is no longer that of “transportation” but a package of services enabling access to different forms of mobility. Therefore it is transport governance that can be a problem. How to federate all mobility stakeholders in France? This dimension is essential for public transport authorities. It is a key success factor for achieving ambitious and sustainable urban planning policies.

Dynamic changes in the business environment requires their business process to be up-to-date. The Workflow Management Systems supporting these business processes need to adapt to these changes rapidly. The Work Flow Management Systems however lacks the ability to dynamically propagate the process changes to their process model schemas (Workflow templates). The literature on workflow schema evolution emphasizes the impact of changes in control flow with very ittle attention to other aspects of a workflow schema. This thesis studies the data aspect (data flow and data model) of workflow schema during its evolution. Workflow schema changes can lead to inconsistencies between the underlying database model and the workflow. A rather straight forward approach to the problem would be to abandon the existing database model and start afresh. However this introduces data persistence issues. Also there could be significant system downtimes involved in the process of migrating data from the old database model to the current one. In this research we develop an approach to address this problem. The business changes demand various types of control flow changes to its business process model (workflow schema). The control flow changes include task insertion, deletion, swapping, movement, replacement, extraction, in-lining, Parallelizing etc. Many of the control flow changes to the workflow can be made by using the combination of a simple task insertion and deletion, while some like embedding task in loop/ conditional branch and Parallelizing tasks also requires the addition/removal of control dependency between the tasks. Since many of the control flow change patterns involves task insertion and deletion at its core, in this thesis we study its impact on the underlying data model. We propose algorithms to dynamically handle the changes in the underlying relational database schema. First we identify the basic change patterns that can be implemented using atomic task insertion and deletions. Then we characterize these basic pattern in terms of their data flow anomalies (Missing, Redundant, Conflicting data) that they can generate. The Data schema compliance criteria are developed to identify the data changes: (i) that makes the underlying database schema inconsistent with the modified workflow and (ii) generating the aforementioned data anomalies. The Data schema compliance criteria characterizes the change patterns in terms of its ability to work with the current relational data model. The Data schema compliance criteria show various properties required of the modified workflow to be consistent with the underlying database model. The data of any workflow instance conforming to Data schema compliance criteria can be directly accommodated in the database model. The data anomalies (of task insertion and deletion) identified using DSC are handled dynamically using respective Data adaptation algorithms. The algorithm uses the functional dependency constraints in the relational database model to adapt/handle these data anomalies. Such handled data (changes) that conform to DSC can be directly accommodated in the underlying database schema. Hence with this approach the workflow can be modified (using task insertion and deletion) and their data changes can be implemented on-the-fly using the Data adaptation algorithms. In this research the same old data model is evolved without abandoning it even after the modification of the workflow schema. This maintains the old data persistence in the existing database schema. Detailed implementation procedures to deploy the Data adaptation algorithms are presented with illustrative examples.

Abstract Cold is a very common physical risk factor in workplaces in circumpolar regions. Cold has many detrimental effects on human health and performance, and on the safety, quality and productivity of work. In this study a systematic general Cold Risk Management Model was developed, applied and evaluated. The model can be integrated in a company’s or an organization’s occupational safety, health, environment and quality (SHEQ) management systems and practices in workplaces. The Cold Risk Management Model and methods were later included in ISO 15743 Ergonomics of the thermal environment – Cold workplaces – Risk assessment and management. The Cold Risk Management Model and methods were applied in two case company’s SHEQ systems and practices in the fields of construction and maritime administration and services. Based on the case studies, the concrete cold risk management activities and the personnel training campaign resulted in immediate positive results and improved attitudes towards further development. At the national level, working in the cold was estimated to increase personnel costs in the construction industry annually by €50M, which is 3% of the industry’s annual personnel costs. This study also showed that the Cold Risk Management Model and methods are profitable. In the case construction company, the savings achieved by cold risk management activities at a construction site were 2.5 time the costs of those activities. A follow-up study in the case company in the field of maritime administration and services showed that implementation and dissemination of the Cold Risk Management Model and methods require systematic work also after the initial development process. The implementation process could and should be enhanced by early establishment of organization-wide guidelines, visible concrete actions, a training campaign and use of necessary external experts. This study also presents a Safety Management Matrix Model for analyzing development and implementation activities during the process time span. / Tiivistelmä Kylmä on yksi yleisimmistä työympäristön riskitekijöistä pohjoisissa oloissamme. Kylmästä aiheutuu haittaa ihmisen toimintakyvylle ja terveydelle sekä työn turvallisuudelle, laadulle ja tuottavuudelle. Tässä väitöstutkimuksessa kehitettiin systemaattinen kylmäriskien hallintamalli osaksi yrityksen työterveys- ja työturvallisuus-, ympäristö- ja laatujohtamisjärjestelmiä (SHEQ). Kehitetty kylmäriskien hallintamalli menetelmineen on nykyisin osa standardia ”SFS-EN ISO 15743 Lämpöolojen ergonomia. Kylmät työpaikat. riskin arviointi ja hallinta”. Kylmäriskien hallintamallia ja sen menetelmiä sovellettiin ja edelleen kehitettiin kahdessa tapausyrityksessä rakennusalalla sekä merenkulun tukipalveluissa. Konkreettisista kehittämistoimenpiteistä ja henkilöstön koulutuksesta koettiin tapausyrityksissä saadun välitöntä hyötyä, ja ne johtivat positiivisiin asenteisiin jatkokehittämistyötä kohtaan. Tutkimuksessa arvioitiin kylmätyön myös lisäävän rakennusalan henkilöstökustannuksia vuosittain 50 miljoonalla eurolla, mikä oli 3 % alan vuotuisista palkkakustannuksista. Tapaustutkimuksen avulla osoitettiin, että kylmänhaittojen hallinta on kannattavaa. 20 henkilön rakennustyömaalla kylmänhaittojen hallinnalla saavutettavat säästöt olivat 2,5-kertaiset toimenpiteistä aiheutuneisiin kuluihin verrattuina. Merenkulun tukipalvelujen alalla toimivassa tapausyrityksessä tehdyn seurantatutkimuksen mukaan kylmäriskien hallintamallin käyttöönotto ja levittäminen yrityksessä vaatii kuitenkin aikaa ja systemaattista työtä. Mallin käyttöönottoa ja levittämistä voidaan tutkimuksen perusteella nopeuttaa kehittämistyön näkyvyydellä ja konkreettisuudella, koulutuksella, organisaatiotasoisten ohjeiden laatimisella aikaisessa vaiheessa sekä erityisesti asiantuntijatuen saatavuudella koko implementointivaiheen ajan. Tutkimuksessa syntyi myös turvallisuusjohtamismatriisi työkaluksi kehittämistyön suunnitteluun ja arviointiin.

Modern science relies on workflow technology to capture, process, and analyse data obtained from scientific instruments. Scientific workflows are precise descriptions of experiments in which multiple computational tasks are coordinated based on the dataflows between them. Orchestrating scientific workflows presents a significant research challenge: they are typically executed in a manner such that all data pass through a centralised computer server known as the engine, which causes unnecessary network traffic that leads to a performance bottleneck. These workflows are commonly composed of services that perform computation over geographically distributed resources, and involve the management of dataflows between them. Centralised orchestration is clearly not a scalable approach for coordinating services dispersed across distant geographical locations. This thesis presents a scalable decentralised service-oriented orchestration system that relies on a high-level data coordination language for the specification and execution of workflows. This system's architecture consists of distributed engines, each of which is responsible for executing part of the overall workflow. It exploits parallelism in the workflow by decomposing it into smaller sub-workflows, and determines the most appropriate engines to execute them using computation placement analysis. This permits the workflow logic to be distributed closer to the services providing the data for execution, which reduces the overall data transfer in the workflow and improves its execution time. This thesis provides an evaluation of the presented system which concludes that decentralised orchestration provides scalability benefits over centralised orchestration, and improves the overall performance of executing a service-oriented workflow.

Indicators were created and developed a performance evaluation tool for the management of healthcare waste integrated with environmental management systems, occupational health and safety; to further identify the predominant model RSS management in each organization investigated. We used the method of multiple case study, through exploratory research, qualitative in nature. The main sources of evidence in the triangulation of data were: a semi-structured interview and the identification form the predominant model for assessing the RSS management systems in the hospital; structured questionnaires; documentary research, and direct non-participant observation conducted in selected health organizations. There was a content analysis, which had the category and subcategory dimensions (operational, administrative, environmental and financial) and parameters of the assessment tool proposed. The results indicated that all hospitals need improvement. The operational dimension presented greater relevance, while the financial dimension is the lowest maturity by limitations on resources. All hospitals investigated were classified as organizations with an RSS management, but need improvement. The RSS management goes beyond the implementation of an ideal management system for the proper management of RSS, as it is also necessary that the individual has commitment and values of citizenship and ethics, responsibility and solidarity in the exercise of their daily activities in this process. It is believed that this evaluation can help improve the GRSS, serving as instrumental for managers assess the management system of the RSS, with the support of prevailing models, favoring strategic decisions to improvements in all worked dimensions in an integrated way. / O objetivo da pesquisa foi avaliar o desempenho dos sistemas de gerenciamento de resíduos de serviços de saúde em organizações hospitalares, na visão de seus gestores. Foram criados indicadores e desenvolvido um instrumento de avaliação de desempenho do gerenciamento de resíduos de serviços de saúde integrado com os sistemas de gestão ambiental, de saúde e segurança ocupacional; para posteriormente identificar o modelo preponderante de gerenciamento de RSS em cada organização investigada. Utilizou-se o método estudo de casos múltiplos, por meio de pesquisa tipo exploratória, de natureza qualitativa. As principais fontes de evidência na triangulação dos dados foram: a entrevista semiestruturada e o formulário de identificação do modelo preponderante para avaliação dos sistemas de gerenciamento de RSS no hospital; os questionários estruturados; a pesquisa documental e a observação direta não participante realizadas nas organizações de saúde selecionadas. Fez-se uma análise de conteúdo, que teve como categoria e subcategoria as dimensões (operacionais, administrativas, ambientais e financeiras) e parâmetros do instrumento de avaliação proposto. Os resultados indicaram que todos os hospitais necessitam de melhorias. A dimensão operacional apresentou maior relevância, enquanto que a dimensão financeira é a de menor maturidade pelas limitações dos recursos. Todos os hospitais pesquisados foram classificados como organizações que possuem um gerenciamento de RSS, mas necessitam aperfeiçoamento. O gerenciamento de RSS vai além da implantação de um sistema de gestão ideal para o manejo adequado dos RSS, pois é necessário também que o indivíduo tenha comprometimento e valores de cidadania e ética, responsabilidade e solidariedade no exercer de suas atividades cotidianas neste processo. Acredita-se que a presente avaliação possa auxiliar na melhoria do GRSS, servindo de instrumental para os gestores avaliarem o sistema de gerenciamento dos RSS, com o apoio dos modelos preponderantes, favorecendo decisões estratégicas, para a melhoria de todas as dimensões trabalhadas de forma integrada.

The advance of the internet and Web 2.0 technologies continue to drive a dramatic change in the way people access and share information through various channels of communication. In the education sector, several learning management systems have been integrated into teaching and learning activities. To increase more interactivities between teachers and learners, tools for synchronous video conferencing are implemented in universities to enable online education. Prior studies indicate that the adoption and use of the tools in higher education institutions have been substantially expanding, more particularly in developed countries. Therefore, understanding the state of integrating synchronous video conference tools to support teaching and learning activities is important for scholars and academicians as this innovative communication technology is proven to have a substantial impact on quality education and effective learning. In Rwanda, before COVID-19, research on the adoption and use of video conference systems is still scarce. The objective of this study was therefore twofold: (1) to understand the adoption and use of synchronous video conference technologies for teaching and learning purposes and (2) to propose a strategy for effective implementation and value addition of video conferencing tools (VCT) at University of Rwanda. A qualitative method was adopted and case study was used as a research strategy for this research. Meanwhile, the Social-Technical System theory was applied in this research for data collection, analysis and reporting of results. 17 responses from participants (teachers and eLearning Officers) were collected using an online internet-based survey questionnaire. Key findings indicate that the adoption and use of video conference systems was found to be at a lower level and the associated contributing inhibitors were identified and reported in this research. Based on the empirical findings and on the responses from participants, this study proposed a contextual strategy for effective integration of video conference systems at the case study institution. Overall, this study concluded that for an effective delivery of live lectures through webinars enabled by the web-based video conference tools, the 10 elements composing the proposed action-oriented strategy for integrating video conference systems should be taken into consideration by the case study institution. Practical and scientific contributions of this research are reported in this thesis and recommendations for further research in connection with the current one have been also put forward.
