Full textThe objective of this work is the realization of a system allowing to assist the travellers, and to facilitate their movement in normal and degraded functioning of the transport network. This system aims to minimize the waiting time of the travellers, in degraded mode, at exchanges stations and to assure them, as well as possible, the continuity of their journey in the multimodal transport networks. So it improves the quality of the service returned to the travellers in order to inform them. A first part of the work in this thesis concerns conception, development and validation of our approach which allows giving optimal or almost optimal solutions for a normal and disrupted transport system. This approach uses a multi-objective method of search for optimal route which leans on a hybridization between a modified Dijkstra algorithm and a genetic algorithm. The modified Dijkstra algorithm gives us a set of solutions serving as initial population for the genetic algorithm. The modelling of the transport system is represented by multi-zones architecture. This architecture shows us the distributed aspect of the system, and the interactions and the relations which can take place among various zones. We present in this work a Multi-agent system of Help to the Movement. These agents use the module of optimization developed in the first part. Our work is realized within the framework of the "VIATIC-MOBILITE" project, which is the project 6 of the I-Trans Competitiveness cluster

Full textKontinuerlig urban tillväxt, miljöproblem, konkurrens om begränsat utrymme, längre pendlingsavstånd samt behovet av att främja rättvisa och jämlikhet i samhället är de främsta anledningarna till förbättringar av kollektivtrafikens (KT) tjänster och attraktionskraft för att få fler resenärer att byta från bil till KT och därmed en viktig politisk fråga i många länder över hela världen. Den befintliga kopplingen mellan KT-resenärens tillfredsställelse, antalet passagerare och lojalitet visar betydelsen av att förbättra resans övergripande tillfredsställelse. De tre artiklar som ingår i denna licentiatavhandling presenterar en rad tillvägagångssätt och metoder som syftar till att öka den totala tillfredsställelsen med KT i ”från dörr till dörr”-resor samt täcker viktiga frågor som tidigare forskning har misslyckats med att ta itu med. Dessa kunskapsluckor inkluderar de olika behov och prioriteringar som olika typer av resenärer har, utveckling över tid och över geografiska områden som total tillfredsställelse och tillfredsställelse med specifika serviceattribut kan påverkas av samt försummelsen av resans av- och påstigningsdelar. Baserat på den svenska kundtillfredsställelsebarometern Svensk Kollektivtrafikbarometer (SKT) visar en undersökning av bestämningsfaktorerna för KT- tillfredsställelse och deras utveckling över tiden för KT-användare under åren 2001-2013 att (Artikel I): a) det skett en försämring av den sammanlagda tillfredsställelsen med KT i Sverige under de senaste åren som drivits av en minskning av tillfredsställelsen med kundgränssnittet och resans tid; b) att dessa två serviceaspekter samt drift är helt avgörande för övergripande tillfredsställelse och som resenärer konsekvent graderar bland de minst tillfredsställande. Mångfalden av behov och prioriteringar för SKT-resenärer reducerades till 5 distinkta multimodala resenärsgrupper (Artikel II). Dessa resenärsgrupper uppvisade geografiska skillnader och en i mellan-grupper övergripande likhet i vikt som fästs vid serviceattribut. Likväl kan några märkbara skillnader observeras. Serviceattributens betydelse avslöjar övergripande förändringar i uppskattnings- och konsumtionsmål över tid. De mer frekventa KT-användarsegmenten är mer nöjda över hela spektret och kännetecknas av en mer balanserad fördelning av attributens betydelse, medan en av grupperna – bilpendlare på landsbygden - är markant missnöjda med service- och driftattribut. Ett antal både normativa och heuristiska regler för aggregerad tillfredsställelse testas på METPEX-data (A Measurement Tool to determine the quality of the Passenger EXperience) för olika typer av resekonfigurationer (Artikel III). Detta görs för att förstå hur resenärer kombinerar delresors tillfredsställelse i en övergripande utvärdering av hela resan och för att undersöka den relativa betydelsen av tillfredsställelse med påstignings-, huvud- och avstigningsdel för hela reseupplevelsen i ”från dörr till dörr”-resor. Resultaten visar att normativa regler bättre kan återge övergripande resetillfredsställelse än heuristiska regler, vilket tyder på att alla resans delar måste beaktas när man utvärderar den samlade reseupplevelsen. I synnerhet ger viktning av tillfredsställelse med individuella delresor och de upplevda delresornas restider den bästa predikatorn för övergripande resetillfredsställelse, särskilt vid tillämpning av en väntetidsvikt på 3 eller 4 gånger i fordons- eller gångtid. Denna uppsättning artiklar skulle kunna hjälpa myndigheter att bättre utvärdera och tillgodose resenärernas behov genom att stödja tilldelning av resurser och prioriterandet av åtgärder i den mest effektfulla delen i en ”från dörr till dörr”-resa.
El rápido crecimiento urbano, problemas medioambientales, la competencia por el uso de espacios cada vez más limitados, el aumento de la distancia en los viajes pendulares así como la necesidad de fomentar una sociedad más equitativa e igualitaria, son algunas de las principales razones que hacen de la mejora de los servicios de transporte público (TP) y del trasvase de usuarios del transporte privado motorizado al TP una política clave en muchos países del mundo. La relación existente entre la mejora de la satisfacción del usuario de TP con el incremento de usuarios y de su fidelidad, prueban la importancia de mejorar la satisfacción global del usuario con el viaje. Los tres artículos incluidos en esta tesis de mitad de doctorado, en Suecia Licentiate thesis, presentan un variedad de enfoques y métodos que tienen como objetivo incrementar la satisfacción global con los viajes de puerta a puerta (desde el origen hasta el destino final) en los que el transporte público está involucrado, a la par de cubrir cuestiones importantes que no han abordado estudios previos. Estas lagunas de conocimientos incluyen: ignorar las distintas prioridades y necesidades de distintos tipos de viajeros; pasar por alto que tanto la satisfacción global con el viaje como la satisfacción con los atributos específicos del servicio pueden experimentar cambios a lo largo del tiempo y entre diversas zonas geográficas; y, el obviar la importancia que otras etapas del viaje (acceso y egreso), diferentes a la principal, pueden ejercer sobre la valoración global del viaje. Basado en el barómetro sueco de satisfacción del usuario de transporte público (SKT), se estudian los determinantes de la satisfacción con el TP y su evolución temporal, para usuarios de TP y para el período 2001-2013 (Artículo I). El artículo muestra que: a) el deterioro de la satisfacción global con el TP sueco experimentado en los últimos años se debe a la disminución de la satisfacción con el modo en el que la agencia de TP gestiona las quejas y el trato con los usuarios (customer interface), y de la duración del viaje (length of trip time); b) frequencia y la fiabilidad del servicio (operation) se suman a los dos ya mencionados atributos del servicio como factores determinantes de la satisfacción global con el TP. Son precisamente estos tres atributos los que consistentemente reciben unas valoraciones situadas entre las menos satisfactorias. Basándose en las características de tipo socio-económico, en las del viaje y en coeficientes de accesibilidad, se obtienen cinco grupos de viajeros multimodales relativamente homogéneos, los cuales ayudan a simplificar la complejidad existente, en términos de necesidades y prioridades, de todos los viajeros suecos - SKT (Artículo II). Los cinco grupos de viajeros exhiben disparidades geográficas y, en general, una semejanza entre grupos en la importancia atribuida a los atributos del servicio. Sin embargo, existen algunas diferencias notorias. A lo largo del tiempo, los niveles de importancia de los atributos del servicio revelan cambios generales en las apreciaciones y objetivos de consumo. Los grupos de viajeros que viajan más frecuentemente con transporte público están, de forma generalizada, más satisfechos con el viaje y muestran una distribución más equilibrada de la importancia dada a los atributos del servicio. Se hace destacable la marcada insatisfacción que uno de los grupos – los automovilistas rurales pendulares (rural motorist commuters)- muestran con los atributos relacionados con la operación (fiabilidad y frequencia). Una serie de reglas de agregación de la satisfacción del viajero, tanto normativas como heurísticas, son examinadas en el conjunto de datos de METPEX (Una herramienta de medición para determinar la calidad de la experiencia del viajero) para distintos tipos de configuraciones de viaje (Artículo III). El objetivo de este artículo es; entender como los viajeros combinan la satisfacción con cada una de las etapas del viaje en su valoración global del viaje, e investigar la importancia relativa que cada una de las tres etapas del viaje (acceso, principal y egreso) tienen sobre la experiencia de un viaje completo de puerta a puerta. Los resultados muestran que, en comparación con las reglas heurísticas, las reglas normativas pueden reproducir de una mejor manera la satisfacción global con el viaje; indicando que todas las etapas del viaje necesitan ser consideradas cuando se evalúa la experiencia global del viaje. En particular la ponderación de la satisfacción con cada una de los segmentos del viaje[1] con la duración percibida para cada una de los segmentos del viaje produce el mejor indicador de la satisfacción global del viaje, especialmente cuando se aplica una penalización por cada minuto de espera equivalente a 3 o 4 veces el tiempo en movimiento y/o caminando. Éste conjunto de artículos pretende ayudar a las operadores y autoridades pertinentes a evaluar y proveer de la mejor manera posible las necesidades de los viajeros mediante la priorización de medidas y asignación de recursos a la parte más relevante del viaje multimodal puerta a puerta. [1] Un segmento del viaje (trip leg) es la parte más pequeña en la que se descompone un viaje de puerta a puerta. Una etapa del viaje puede estar compuesta de uno o más segmentos del viaje.

Full textThe importance of freight transport is amplified today by the rapid boom in E-commerce, and in particular new online-to-offline business strategies. To boost competitiveness, e-tailers and logistics service providers have devoted adequate efforts to managing express fulfillment services, e.g., same-day delivery (one or two-hour delivery), and various distribution and delivery channels. This has resulted in massive, high-frequency shipments with short lead times and fluctuating volumes. Moreover, freight transport organizations have undergone rapid changes. New markets and new technologies have emerged that will probably require innovative solutions as efficiency is still low. There is thus a strong motivation, involving economic, social, and environmental objectives, to develop more sustainable and efficient freight transport systems. In this vein, horizontal collaboration has been largely studied, and its effectiveness and efficiency in freight transport have been proven in the recent literature (Pan et al., 2019). In particular, Collaborative Transport Networks are a horizontal collaboration solution attracting increasing attention. Given the important role of freight transport in logistics and the multiple, compounding challenges faced by actors, an innovative, effective, and sustainable management of transport services procurement is needful for the emerging new collaborative transport networks. Moreover, new collaborative incentive mechanisms and rules are required to manage interactions between all the independent stakeholders in such networks. This dissertation intends to explore collaborative mechanisms that manage the interactions between actors and guide the self-interested decisions of individuals toward an optimal global solution in such a way that these individuals are motivated to choose the optimal and rational solutions. This dissertation provides a picture of existing mechanisms for freight transport service procurement, challenges components of existing research, and provides ground for further research

Full textNowadays, information related on displacement and mobility in a transport network represents certainly a significant potential. So, this work aims to modeling, to optimize and to implement an Information System of Services to Aid the Urban Mobility (ISSAUM).The ISSAUM has firstly to decompose each set of simultaneous requests into a set of sub-requests called tasks. Each task corresponds to a service which can be proposed different by several information providers with different. An information provider which aims to propose some services through our ISSAUM has to register its ontology. Indeed, ISSAUM is related to an Extended and distributed Transport Multimodal Network (ETMN) which contains several heterogeneous data sources. The dynamic and distributed aspects of the problem incite us to adopt a multi-agent approach to ensure a continual evolution and a pragmatic flexibility of the system. So, we proposed to automate the modeling of services by using ontology idea. Our ISSAUM takes into account possible disturbance through the ETMN. In order to satisfy user requests, we developed a negotiation protocol between our system agents. The proposed ontology mapping negotiation model based on the knowledge management system for supporting the semantic heterogeneity and it organized as follow: Negotiation Layer (NL), the Semantic Layer (SEL), and the Knowledge Management Systems Layer(KMSL).We detailed also the reassignment process by using Dynamic Reassigned Tasks (DRT) algorithm supporting by ontology mapping approach. Finally, the experimental results presented in this thesis, justify the using of the ontology solution in our system and its role in the negotiation process

Full textThis doctoral thesis contributes to the implementation of a decision support system for the traffic control in the disrupted transport networks, aiming to help the developers of these networks to dissipate the disturbances which can appear and degrade the quality of services offered to the travellers. This report is consisted of four chapters. It begins with a bibliographical study on the management of collective transport networks. So, we approach the various problems related to transport systems, to processes planning and regulation. The second chapter presents various models attributed to the multimodal transport systems such as those based on the theory of graphs, on multi-agents systems, and on Petri nets. We also propose a new mathematical formulation of the problem of regulation and a help module to the generation and to the evaluation of the regulation strategies. This module is constituted with four sub-modules; each one realizes a very precise task: the evaluation of impact of disturbances and the actions of regulation on the state of the traffic, the determination of the spatiotemporal horizon of regulation, the generation of practicable decisions and their construction. Four evolutionary-fuzzy approaches proposed for the resolution of this problem are presented in the chapter 3. The fourth chapter is dedicated to the results of the implemented of approaches and methods proposed through the tests of simulation, to evaluate their performances on some real scenarios of different natural disturbances and stemming from the transport network of our industrial partner of the SART project : the SEMURVAL

Full textTo plan his travel, a traveller has to consult several web sites of different public transport operators. To avoid this time consuming task, this work consists in conceiving a Mobility Cooperative information system (SICM) providing a multi-modal and a multi-operators travel information. This integration system automates the itineraries search and the multi-operators routes composition. Its design is based on the multiagent system theory (MAS). The SICM tries, in fact, to make the existing operators’ information systems cooperating efficiently together, so that it can provide users with the optimized route to follow, by compiling the needed information from the different operators information sources. In this approach, the SICM is a middleware which becomes a customer among other users of the existing information systems. It can be considered as a mediator between the various distributed information sources on the one hand and the travellers on the other hand. The system should be able, at the same time, to find the needed information sources which are able to answer an itinerary request, and to gather this information in a coherent way to compose an optimized itinerary. To provide an optimized route, according to the criterion of the user, distributed and time-dependent shortest path algorithms were adopted and adapted to realize an on-line itinerary composition

Full textThis research work compares the options of monomodality, intermodality and multimodality to the transport of bulk grains from the western region of Paran?. The purpose of the research was to identify the reasons for the low utilization of waterways in comparison with the highways and railways, in this region. In order to do this, were found the main features of the load transport through each of these modal ones, and the performance of the maritime ports of Santos (SP) and Paranagu? (PR), regarded as the most suitable for export such production. The data has been collected from primary sources, by the technique of in situ observation made in river and raiwayl terminals and guided unstructured interviews with some professionals responsible for the logistics of companies engaged in the marketing of grain in the region. It has been used some documentary research to gather secondary data, concerning the characteristics of transport and freight prices. The analysis of content was made through comparison between prices of freight, losses, and the impact in the costs related to the environmental costs, of each simulated arrangement. It found out that the preference in the region for road modal occurs mainly due to the lack of infrastructure logistics for the other modal ones. In the comparison of performance, the Port of Santos presents minor average time of wait to moor a ship than the Port of Paranagu?. It was concluded that the waterway is an alternative to the costs reduction of transport in the region and that there is a latent demand for joint efforts of public and private initiative to reach the solution of the existing deficiencies for the transport of agricultural production of the western region of Paran
Este trabalho de pesquisa compara as opções de monomodalidade, intermodalidade e multimodalidade para o transporte de granéis agrícolas da região Oeste do Paraná. O propósito foi identificar as razões da pouca utilização da hidrovia em comparação à rodovia e ferrovia, nessa região. Para isso, foram levantadas as principais características dos transportes de carga, por meio de cada um desses modais, e o desempenho dos portos marítimos de Santos (SP) e Paranaguá (PR), considerados como destinos mais apropriados para exportação dessa produção. Os dados foram coletados de fontes primárias, a partir da técnica de observação in loco, realizadas nos terminais fluvial e ferroviário, e de entrevistas não estruturadas, guiadas, com alguns profissionais responsáveis pela logística de empresas atuantes na comercialização de grãos da região. Utilizou-se de pesquisa documental para a coleta de dados secundários, referentes às características dos transportes e preços dos fretes. A análise do conteúdo foi feita por comparação entre os preços de fretes, perdas, e impacto nos custos relacionados aos problemas ambientais, de cada arranjo simulado. Constatou-se que a preferência na região pelo modal rodoviário ocorre principalmente devido à falta de infra-estrutura logística para os outros modais. Na comparação de desempenho portuário, o Porto de Santos apresenta menor tempo médio de espera para atracamento dos navios, do que o Porto de Paranaguá. Concluiu-se que a utilização da hidrovia é uma alternativa para redução dos custos de transporte na região e há uma demanda latente na região por esforços conjuntos da iniciativa pública e privada para a solução das deficiências existentes no escoamento da produção agrícola da região Oeste do Paraná.

Full textThese works, based on a multiagent organization, are related to the personalization in the information systems. The personalization consists in adapting information and their presentation according to the needs, the capacities, the preferences of the users and the context of the requests. Our contribution consists in proposing a flexible and co-operating multiagent organization (MAPIS) able to connect the heterogeneous and distributed data retrieved by exploiting the agents mobility with the profiles of the users. The profiles are updated thanks to the agents capacities of learning. We have applied this work to a multimodal information system (AgenPerso) for the surface transport. The aim of the system is to propose personalized routes. This work will have several future works: theoretical (by the MAPIS formalization and its evolution towards a tool for the design of personalized information systems) and applicative (by the enrichment of the new services in AgenPerso)

Full textOne of solutions to regulate and rationalize the physical displacement of goods is to succeed to synchronize the physical flow with its informational counterpart throughout the various links constituting the transport chain. In this context, a solution of goods tracking and tracing can contribute to a better mastery of flows. In this memory, we propose a data modeling approach for goods traceability based on innovative research approaches (PLM, Intelligent product, Product centered systems) and taking into account the possibilities offered by the use of NICT in terms of data sharing, auto-identification and geolocation. Then, in order to integrate our traceability data with the other transport chain data, but also in order to facilitate the sharing and the exchange of our data, we propose a modeling and the development of an intermediation platform based on the web services logic. Meeting criteria of interoperability and integrability, the result allows through mechanisms for exchange and saving data to follow and to restore goods lifecycle in its entirety

Full textCes travaux de recherche visent à mettre en œuvre un Système d'Information de Transport Multimodal (SITM) pour optimiser la gestion de flux des requêtes utilisateurs qui peuvent être nombreuses et simultanées. Dans ce cas, le SITM doit pouvoir procéder par des processus de décomposition des requêtes simultanées en un ensemble de tâches indépendantes. Chaque tâche correspond à un service qui peut être proposé par plusieurs fournisseurs d'information, en concurrence, avec différents couts, formats et temps de réponse. Un fournisseur d'information voulant proposer ses services via le SITM, doit d'abord y enregistrer son système d'information, en assumant la responsabilité des aspects juridiques et qualitatifs de ses données. Le SITM est donc lié à un Réseau informatique Etendu et distribué de Transport Multimodal (RETM) qui comporte plusieurs sources d'information hétérogènes des différents services proposés aux utilisateurs de transport.
L'aspect dynamique, distribué et ouvert du problème, nous a conduits à adopter une modélisation multi-agent pour assurer au système une évolution continue et une flexibilité pragmatique. Le système multi-agent proposé s'appuie sur les métaheuristiques pour la recherche et la composition des services; la recherche des services se base sur le paradigme Agent Mobile (AM) utilisant un algorithme d'optimisation dynamique de construction des Plans De Routes (PDR). Cette première étape d'optimisation prépare les parcours des AMs en prenant en considération l'état du RETM. La composition des services utilise les algorithmes évolutionnistes pour optimiser les réponses en termes de coût et de temps, sachant qu'une réponse à une requête utilisateur ne doit pas dépasser un temps maximum autorisé et qu'un utilisateur cherche toujours à avoir le meilleur rapport qualité prix pour les services qu'il demande.
Enfin, le SITM prend en considération les éventuelles perturbations sur le RETM (pannes, goulets d'étranglements, etc.) pour satisfaire les requêtes utilisateurs dans tous les cas de figure. Dans ce contexte, nous avons créé un protocole de négociation entre les agents mobiles et les agents responsables des choix des fournisseurs d'information pour les services demandés, ces agents sont appelés agents Ordonnanceurs. Le protocole proposé dépasse les limites d'une communication agent traditionnelle, ce qui nous a incités à associer au système une ontologie flexible qui permet d'automatiser les différents types d'échanges entre les agents grâce à un vocabulaire approprié.
Les résultats expérimentaux présentés dans cette thèse justifient l'utilisation du paradigme agent mobile dans notre système qui remplace parfaitement bien les paradigmes classiques telle que l'architecture client/serveur. Les simulations présentées montrent différents scénarios de gestion d'un nombre des requêtes simultanées plus ou moins important. En effet, quelque soit le nombre de requêtes utilisateurs formulées pendant un court laps de temps , le système se charge de leur décomposition, de l'identification des services demandés et des fournisseurs d'information susceptibles d'y répondre.

Full textThe physical internet is an innovative concept that ultimately allows the reorganization of the supply chain into a single large open network through the interconnection of logistics networks in a standardized way, through collaboration protocols, with modular containers and by communication platforms. The study undertaken by this thesis focuses on the understanding of this new logistics network and the conditions of its deployment on the real plane based on the analysis of a set of logistical innovations that preceded it. The innovations selected all have a similarity to the physical Internet (one of its components). The chosen method was to understand the path of success and deployment of these innovations, for the one to compare with the physical internet. The innovations selected (containerization, pooling and freight exchanges among others) made it possible to conduct this analysis based on certain theories of innovation and the economy of services. The result is that one of the major obstacles to the deployment of the physical internet is its lack of maturity from a service point of view and the incomplete integration of all potential users of the new network (small players in particular) in the design of the service
