description Publicationkeyboard_double_arrow_right Preprint , Article 2024Publisher:Elsevier BV Authors: Clara Buire; Aude Marzuoli; Daniel Delahaye; Marcel Mongeau;Clara Buire; Aude Marzuoli; Daniel Delahaye; Marcel Mongeau;This study addresses the integration of the railway and airline scheduling problems, in order to offer passengers smooth transfers between rail and air. This paper focuses on optimizing the air and rail timetables at 18 major European airports including three hubs and their associated train stations. A multimodal passenger demand simulation, using constraint programming and based on real data, is proposed. Six days in December 2019 are analyzed, and ten simulations per day are performed. These instances are publicly released. The air-rail timetable synchronization is applied to these 60 simulated days. Three scenarios are tested in which each operator agrees to change its schedule or not. Results show that changing only 13% of European flights by 11 minutes on average could increase the number of suitable connections for passengers by 60%. In addition, if both airlines and railway operators adapt their schedules, passenger comfort is improved and operator costs are reduced, even more so than with unilateral changes.

This article tackles this gap in research by statistically analyzing data on global shipping flows across nearly 5000 ports in 35 OECD countries between 2001 and 2018. The different traffic types, from containers to bulk and passengers, are analyzed jointly with data on natural conditions, air pollution, socio-economic indicators, and public health. The principal results show that port regions pollute more than non-port regions on average, while health impacts vary according to the size and specialization of the port region. Three types of port regions are clearly differentiated: industrial, intermediate, and metropolitan port regions.

It leverages the temporal sequences of flight data to delineate various phases of an aircraft’s journey, making it a valuable tool for enhancing the anal- ysis of flight performance and safety. In this work, we implement a multivariate HMM to identify 6 flight phases: taxi, takeoff, climb, cruise, approach and rollout. We reach a median global accuracy of about 97% over a sample of several thousand flights with a very low number of decoded unlikely transitions. Regarding several performance metrics, our method is competitive with existing methods in the litera- ture, such as fuzzy logic. Additionally, it provides, for each point of the flight, a probability of belonging to each phase. Even in situations where there are missing values in the data, HMMs remain effective, ensuring that no critical information is lost during the segmentation process. We show that HMMs work seamlessly with the fine granularity of Flight Data Recorder (FDR) data. HMMs offer remarkable flex- ibility and adaptability, proving particularly effective when the number or order of phases is unknown or not predetermined, as is often the case with complex flight scenarios such as helicopter flights. This adaptability is crucial for handling the diverse range of flight operations that differ from one aircraft to another. An example is given with the segmentation of an Automatic Dependent Surveillance–Broadcast (ADS-B) helicopter flight operated by the Swedish National Police.

Their reverse logistic requires solving a continent-scale multiattribute inventory routing problem (IRP). With an average of 30 commodities, 16 depots, and 600 customers spread across a continent, our instances are orders of magnitude larger than those in the literature. Existing algorithms do not scale, so we propose a large neighborhood search (LNS). To make it work, (1) we generalize existing split delivery vehicle routing problems and IRP neighborhoods to this context, (2) we turn a state-of-the-art matheuristic for medium-scale IRP into a large neighborhood, and (3) we introduce two novel perturbations: the reinsertion of a customer and that of a commodity into the IRP solution. We also derive a new lower bound based on a flow relaxation. In order to stimulate the research on large-scale IRP, we introduce a library of industrial instances. We benchmark our algorithms on these instances and make our code open source. Extensive numerical experiments highlight the relevance of each component of our LNS.

In urban settings, this issue is often dealt with by partitioning the geographical area around a depot into service zones, each served by a single vehicle. Such zones ultimately guide daily routing decisions. We study the problem of determining the optimal partitioning of an urban logistics area served by EVs. We cast this problem in a Continuous Approximation (CA) framework. Considering a ring radial region with a depot at its center, we introduce the electric vehicle fleet sizing problem (EVFSP). As the current range of EVs is fairly sufficient to perform service in urban areas, we assume that the EV fleet is exclusively charged at the depot, i.e., en-route charging is not allowed. In the EVFSP we account for EV features such as limited range, and non-linear charging and energy pricing functions stemming from Time-of-use (ToU) tariffs. Specifically, we combine non-linear charging functions with pricing functions into charging cost functions, establishing the cost of charging an EV for a target charge level. We propose a polynomial time algorithm for determining this function. The resulting function is non-linear with respect to the route length. Therefore, we propose a Mixed Integer Non-linear Program (MINLP) for the EVFSP, which optimizes both dimensions of each zone in the partition. We strengthen our formulation with symmetry breaking constraints. Furthermore, considering convex charging cost functions, we show that zones belonging to the same ring are equally shaped. We propose a tailored MINLP formulation for this case. Finally, we derive upper and lower bounds for the case of non-convex charging cost functions. We perform a series of computational experiments. Our results demonstrate the effectiveness of our algorithm in computing charging cost functions. We show that it is not uncommon that these functions are non-convex. Furthermore, we observe that our tailored formulation for convex charging cost functions improves the results compared to our general formulation. Finally, contrary to the results obtained in the CA literature for combustion engine vehicles, we empirically observe that the majority of EVFSP optimal solutions consist of a single inner ring.

This study explores the potential of using Electric Vehicles (EVs) batteries for renewable energy storage through a Vehicle-to-Grid (V2G) system. We argue that V2G requires nuanced coordination for using EVs as mobility and storage resources facilitated by an aggregator acting as an intermediary. Emphasizing the importance of information in this coordination, we develop a theoretical framework addressing the value of information for V2G aggregators. We implement the theoretical framework in an analysis focusing on the often-overlooked aspect of the business models that might enable the information flow between an aggregator and EV owners. A multi-agent simulation in Tenerife 2040 evaluates four scenarios, each assuming that EVs are coordinated by different types of mobility apps, i.e., a decision support system that helps EV owners reserve charging stations or route navigation. The results reveal that EV owners' charging behavior information is the most important for a V2G aggregator, yet when mobility information is also considered, the value of V2G increases by a factor of six. This insight informs the development of future business models for sustainable and efficient decarbonized electric systems.

We formalize and solve this problem by maximizing social welfare under a budget constraint. The personalized incentives depend on the alternatives available to each individual and on her preferences. A polynomial time approximation algorithm computes a policy within few seconds. We analytically prove that it is boundedly close to the optimum. We efficiently calculate the curve of social welfare achievable for each value of budget within a given range. This curve can be useful for the regulator to decide the appropriate amount of budget to invest. We extend our formulation to enforcement, taxation and non-personalizedincentive policies. We analytically show that our personalized-incentive policy is also optimal within this class of policies and construct close-to-optimal enforcement and proportional tax-subsidy policies. We then compare analytically and numerically our policy with other state-of-the-art policies. Finally, we simulate a large-scale application to mode choice to reduce CO2 emissions.

Notre objectif est de comprendre comment cette coordination est réalisée, quelles sont les démarches des acteurs locaux et comment ils mettent en œuvre cette stratégie. Pour ce faire, nous nous appuyons sur des analyses bibliographiques, des documents d'urbanisme et des informations recueillies lors d'entretiens semi-directifs auprès d'élus, de personnels des collectivités locales, d'associations et de spécialistes dans les deux zones d'étude retenues. A l'aide d'une grille d'analyse basée sur les grandes théories de la gouvernance, notre objectif est de mettre en évidence les outils d'action publique mis en œuvre pour répondre aux enjeux singuliers des territoires de faible densité. Selon notre hypothèse, nous pensons qu'une stratégie partenariale incluant différents acteurs publics et commerciaux conduit à l'appropriation des politiques de planification urbaine et de coordination des transports ferroviaires. Cependant, le degré de participation et de coordination peut fluctuer d'une région à l'autre. De plus, dans ces territoires peu denses, les acteurs locaux mobilisent quatre principaux leviers d'actions publiques : renforcer l'attractivité des gares et la densification des quartiers de gare, améliorer l’offre ferroviaire et l'intermodalité, améliorer la gouvernance, et encourager les projets de territoire en lien avec l'axe ferroviaire. This paper examines two case studies; the B ́earn region in France and the canton of Jura in Switzerland, to investigate how urban planning and rail transportation are coordinated in sparsely populated areas. Our goal is to comprehend how this coordination is carried out, what steps local actors take, and how they implement this strategy. To achieve this, we use bibliographical analyses, urban planning papers, and information gathered from semi-directive interviews with elected officials, local government personnel, associations, and specialists in the two study areas that were chosen. Employing an analysis grid based on important theories of governance, our aim is to highlight the public action tools used to meet the unique issues of low-density territories. According to our hy- pothesis, we think that a partnership strategy including various public and commercial actors leads to the appropriation of urban planning and rail transport coordination policies. However, the degree of participation and coordination may fluctuate between various regions. Additionally, in these sparsely populated locations, native performers use four basic pil- lars of action: boosting station appeal and station quarter densification, enhancing rail service and intermodality, enhancing governance, and en- couraging projects in the vicinity of the rail axis.

This paper analyzes the factors influencing present and future SAF market availability – namely resources, technologies, and costs – and attempts to assess the credibility of current SAF development scenarios. Our findings highlight two main challenges: (1) short-term capacity building of an SAF industry still stuck in its infancy, and (2) mid to long-term disproportionate resource requirements. Significant investments from all the industry players, not just energy providers and states, as well as dedicated regulations, are required to overcome the technology, energy, investment, and cost barriers hindering SAF development. Another issue concerns the sustainability of the sector’s future demand expansion. The envisioned growth rates will induce excessive biomass, hydrogen, and electricity consumption, jeopardizing other sectors’ transition pathways. Overall, the analysis questions the relevance of the resource allocation implicitly used in current industry scenarios for 2050, an assumption with essential environmental, social, and ethical implications. Against this background, policies aimed at lowering demand expansion seem unavoidable if there is any chance of achieving net zero by 2050.

This paper focuses on optimizing the air and rail timetables at 18 major European airports including three hubs and their associated train stations. A multimodal passenger demand simulation, using constraint programming and based on real data, is proposed. Six days in December 2019 are analyzed, and ten simulations per day are performed. These instances are publicly released. The air-rail timetable synchronization is applied to these 60 simulated days. Three scenarios are tested in which each operator agrees to change its schedule or not. Results show that changing only 13% of European flights by 11 minutes on average could increase the number of suitable connections for passengers by 60%. In addition, if both airlines and railway operators adapt their schedules, passenger comfort is improved and operator costs are reduced, even more so than with unilateral changes.

This article tackles this gap in research by statistically analyzing data on global shipping flows across nearly 5000 ports in 35 OECD countries between 2001 and 2018. The different traffic types, from containers to bulk and passengers, are analyzed jointly with data on natural conditions, air pollution, socio-economic indicators, and public health. The principal results show that port regions pollute more than non-port regions on average, while health impacts vary according to the size and specialization of the port region. Three types of port regions are clearly differentiated: industrial, intermediate, and metropolitan port regions.

It leverages the temporal sequences of flight data to delineate various phases of an aircraft’s journey, making it a valuable tool for enhancing the anal- ysis of flight performance and safety. In this work, we implement a multivariate HMM to identify 6 flight phases: taxi, takeoff, climb, cruise, approach and rollout. We reach a median global accuracy of about 97% over a sample of several thousand flights with a very low number of decoded unlikely transitions. Regarding several performance metrics, our method is competitive with existing methods in the litera- ture, such as fuzzy logic. Additionally, it provides, for each point of the flight, a probability of belonging to each phase. Even in situations where there are missing values in the data, HMMs remain effective, ensuring that no critical information is lost during the segmentation process. We show that HMMs work seamlessly with the fine granularity of Flight Data Recorder (FDR) data. HMMs offer remarkable flex- ibility and adaptability, proving particularly effective when the number or order of phases is unknown or not predetermined, as is often the case with complex flight scenarios such as helicopter flights. This adaptability is crucial for handling the diverse range of flight operations that differ from one aircraft to another. An example is given with the segmentation of an Automatic Dependent Surveillance–Broadcast (ADS-B) helicopter flight operated by the Swedish National Police.

Their reverse logistic requires solving a continent-scale multiattribute inventory routing problem (IRP). With an average of 30 commodities, 16 depots, and 600 customers spread across a continent, our instances are orders of magnitude larger than those in the literature. Existing algorithms do not scale, so we propose a large neighborhood search (LNS). To make it work, (1) we generalize existing split delivery vehicle routing problems and IRP neighborhoods to this context, (2) we turn a state-of-the-art matheuristic for medium-scale IRP into a large neighborhood, and (3) we introduce two novel perturbations: the reinsertion of a customer and that of a commodity into the IRP solution. We also derive a new lower bound based on a flow relaxation. In order to stimulate the research on large-scale IRP, we introduce a library of industrial instances. We benchmark our algorithms on these instances and make our code open source. Extensive numerical experiments highlight the relevance of each component of our LNS.

In urban settings, this issue is often dealt with by partitioning the geographical area around a depot into service zones, each served by a single vehicle. Such zones ultimately guide daily routing decisions. We study the problem of determining the optimal partitioning of an urban logistics area served by EVs. We cast this problem in a Continuous Approximation (CA) framework. Considering a ring radial region with a depot at its center, we introduce the electric vehicle fleet sizing problem (EVFSP). As the current range of EVs is fairly sufficient to perform service in urban areas, we assume that the EV fleet is exclusively charged at the depot, i.e., en-route charging is not allowed. In the EVFSP we account for EV features such as limited range, and non-linear charging and energy pricing functions stemming from Time-of-use (ToU) tariffs. Specifically, we combine non-linear charging functions with pricing functions into charging cost functions, establishing the cost of charging an EV for a target charge level. We propose a polynomial time algorithm for determining this function. The resulting function is non-linear with respect to the route length. Therefore, we propose a Mixed Integer Non-linear Program (MINLP) for the EVFSP, which optimizes both dimensions of each zone in the partition. We strengthen our formulation with symmetry breaking constraints. Furthermore, considering convex charging cost functions, we show that zones belonging to the same ring are equally shaped. We propose a tailored MINLP formulation for this case. Finally, we derive upper and lower bounds for the case of non-convex charging cost functions. We perform a series of computational experiments. Our results demonstrate the effectiveness of our algorithm in computing charging cost functions. We show that it is not uncommon that these functions are non-convex. Furthermore, we observe that our tailored formulation for convex charging cost functions improves the results compared to our general formulation. Finally, contrary to the results obtained in the CA literature for combustion engine vehicles, we empirically observe that the majority of EVFSP optimal solutions consist of a single inner ring.

This study explores the potential of using Electric Vehicles (EVs) batteries for renewable energy storage through a Vehicle-to-Grid (V2G) system. We argue that V2G requires nuanced coordination for using EVs as mobility and storage resources facilitated by an aggregator acting as an intermediary. Emphasizing the importance of information in this coordination, we develop a theoretical framework addressing the value of information for V2G aggregators. We implement the theoretical framework in an analysis focusing on the often-overlooked aspect of the business models that might enable the information flow between an aggregator and EV owners. A multi-agent simulation in Tenerife 2040 evaluates four scenarios, each assuming that EVs are coordinated by different types of mobility apps, i.e., a decision support system that helps EV owners reserve charging stations or route navigation. The results reveal that EV owners' charging behavior information is the most important for a V2G aggregator, yet when mobility information is also considered, the value of V2G increases by a factor of six. This insight informs the development of future business models for sustainable and efficient decarbonized electric systems.

We formalize and solve this problem by maximizing social welfare under a budget constraint. The personalized incentives depend on the alternatives available to each individual and on her preferences. A polynomial time approximation algorithm computes a policy within few seconds. We analytically prove that it is boundedly close to the optimum. We efficiently calculate the curve of social welfare achievable for each value of budget within a given range. This curve can be useful for the regulator to decide the appropriate amount of budget to invest. We extend our formulation to enforcement, taxation and non-personalizedincentive policies. We analytically show that our personalized-incentive policy is also optimal within this class of policies and construct close-to-optimal enforcement and proportional tax-subsidy policies. We then compare analytically and numerically our policy with other state-of-the-art policies. Finally, we simulate a large-scale application to mode choice to reduce CO2 emissions.

Notre objectif est de comprendre comment cette coordination est réalisée, quelles sont les démarches des acteurs locaux et comment ils mettent en œuvre cette stratégie. Pour ce faire, nous nous appuyons sur des analyses bibliographiques, des documents d'urbanisme et des informations recueillies lors d'entretiens semi-directifs auprès d'élus, de personnels des collectivités locales, d'associations et de spécialistes dans les deux zones d'étude retenues. A l'aide d'une grille d'analyse basée sur les grandes théories de la gouvernance, notre objectif est de mettre en évidence les outils d'action publique mis en œuvre pour répondre aux enjeux singuliers des territoires de faible densité. Selon notre hypothèse, nous pensons qu'une stratégie partenariale incluant différents acteurs publics et commerciaux conduit à l'appropriation des politiques de planification urbaine et de coordination des transports ferroviaires. Cependant, le degré de participation et de coordination peut fluctuer d'une région à l'autre. De plus, dans ces territoires peu denses, les acteurs locaux mobilisent quatre principaux leviers d'actions publiques : renforcer l'attractivité des gares et la densification des quartiers de gare, améliorer l’offre ferroviaire et l'intermodalité, améliorer la gouvernance, et encourager les projets de territoire en lien avec l'axe ferroviaire. This paper examines two case studies; the B ́earn region in France and the canton of Jura in Switzerland, to investigate how urban planning and rail transportation are coordinated in sparsely populated areas. Our goal is to comprehend how this coordination is carried out, what steps local actors take, and how they implement this strategy. To achieve this, we use bibliographical analyses, urban planning papers, and information gathered from semi-directive interviews with elected officials, local government personnel, associations, and specialists in the two study areas that were chosen. Employing an analysis grid based on important theories of governance, our aim is to highlight the public action tools used to meet the unique issues of low-density territories. According to our hy- pothesis, we think that a partnership strategy including various public and commercial actors leads to the appropriation of urban planning and rail transport coordination policies. However, the degree of participation and coordination may fluctuate between various regions. Additionally, in these sparsely populated locations, native performers use four basic pil- lars of action: boosting station appeal and station quarter densification, enhancing rail service and intermodality, enhancing governance, and en- couraging projects in the vicinity of the rail axis.

The envisioned growth rates will induce excessive biomass, hydrogen, and electricity consumption, jeopardizing other sectors’ transition pathways. Overall, the analysis questions the relevance of the resource allocation implicitly used in current industry scenarios for 2050, an assumption with essential environmental, social, and ethical implications.
