Over the past few decades, intelligent transportation systems (ITS) have emerged as an effective way to improve the performance of transportation systems. ITS provide innovative services, enhance travel safety, provide travellers with more choices, and make transportation systems more efficient. Multi-agent systems (MAS), which define autonomous in...
Le développement de véhicules autonomes, capables de communiquer de pair à pair, ainsi que l’intérêt pour les solutions à la demande (par exemple, Uber, Lyft, Heetch), sont les principales motivations de cette étude. Le problème d’allocation des véhicules aux clients est d’une importance majeure dans la gestion des systèmes de transport à la demand...
One of the main challenges in Industry 4.0 is the supervision and coordination of heterogeneous robots at runtime, especially when they have a certain level of autonomy, as seen in Autonomous Mobile Robots. In addition, autonomous robots and their digital twins are designed by private manufacturers, and their code is often inaccessible. In this stu...
Deploying fleets of Connected Autonomous Vehicles (CAVs), with limited peer-to-peer communication ranges, in order to provide On-demand Transport (ODT) services, requires a careful choice and evaluation of solution methods for resource allocation problems.

Emphasizing the need for transparency and explainability of resource allocation decisions in ODT systems to be understandable by humans and move toward a more controllable resource allocation. We propose in this preliminary work a multi-agent architecture and general implementation guidelines towards meeting these requirements.
The introduction of driver-less technologies can improve on-demand transport (ODT) systems and help make passenger transportation and logistics more efficient. Major issues in managing ODT systems are allocation problems, i.e., finding feasible and good allocations of requests to vehicles. Being autonomous, vehicles in large fleets can make decentr...
On-Demand Transport (ODT) systems have attracted increasing attention in recent years. Traditional centralized dispatching can achieve optimal solutions, but NP-Hard complexity makes it unsuitable for online and dynamic problems. Centralized and decentralized heuristics can achieve fast, feasible solution at run-time with no guarantee on the qualit...

Dans le cadre du transport à la demande (TAD), l'appariement centralisé traditionnel permet d'obtenir des solutions optimales, mais reste NP-difficile et donc inadapté aux problèmes en ligne et dynamiques. Les approches décentralisées permettent d'obtenir des solutions réalisables en temps réel, mais sans garantie de qualité. Ici, nous considérons...
This work is interested in decentrally solving a taxi allocation problem over a fleet of autonomous taxis. Classically, to solve this problem, requests are centralized into a portal where a dispatcher allocates requests to taxis (ideally, in an optimal manner). This requires taxis have continuous access to the portal. However, getting access to suc...

Abstract In this paper, we define the online localized resource allocation problem, especially relevant for modeling transportation applications. The problem modeling takes into account simultaneously the geographical location of consumers and resources together with their online nondeterministic appearance.

The development of surface public transportation networks is a major issue in terms of ecology, economy and society. Their quality in terms of punctuality and passengers services (regularity between buses) should be improved in order to improve their attractiveness. To do so, cities often use regulation systems at intersections that grant priority...
The environment, as a space shared between agents, is a key component of multiagent systems (MAS). Depending on systems, this space may integrate physical, communication or social dimensions.

L'environnement, en tant qu'espace partagé entre agents, est un élément essentiel des systèmes multiagents. Selon les systèmes, cet espace intègre des dimensions différentes comme une dimension physique support à l'ancrage spatial et à l'activité des agents sur cette dimension, ou une dimension sociale support aux communications entre agents. Ces d...
In most multiagent-based simulation (MABS) frameworks, a scheduler activates the agents who compute their context and decide the action to execute. This context computation by the agents is executed based on information about themselves, the other agents and the objects of the environment that are accessible to them. The issue here is the identific...
Awareness is a concept that has been frequently studied in the context of Computer Supported Cooperative Work. However, other fields of computer science can benefit from this concept. Recent research in the multi-agent systems field has highlighted the relevance of complex interaction models such as multi-party communication and context awareness f...

We instantiate the model with the urban parking manage...
In the context of road urban traffic management, the problem of parking spots search is a major issue because of its serious economic and ecological fallout. In this paper, we propose a multi-agent system that aims to decrease, for private vehicles drivers, the parking spots search time. In the system that we propose, a community of drivers shares...
This paper proposes a bimodal urban traffic control strategy based on a multi-agent model. We call bimodal traffic, a traffic which takes into account both private vehicles and public vehicles such as buses. The objective of this research is to improve global traffic, to reduce bus delays and to improve bus regularity in congested areas of the netw...
Agent-based simulation is used to understand complex systems and to experiment several scenarios. In classical simulation frameworks, a pitfall is the fact that the action phase, based on local agent context analysis, is repeated in each agent at each time cycle during the simulation execution. This analysis inside the agents reduces agent flexibil...
The environment is a powerful first-order abstraction in Multi-Agent Systems (MAS), as well as a critical building block. The agents interact in their environment and the effects of their actions are observed and evaluated through this environment. The local complexity of the agents depends on its management of the interaction and action processes....

The environment has emerged as a powerful first-order abstraction in Multi-Agent Systems (MAS), as well as a critical building block. One benefit is to reduce the complexity of the agents by delegating to the environment a part of the tasks of the system. This delegating process provides a flexible way to exchange information and to coordinate the...
This paper proposes a strategy of urban bimodal traffic regulation based on multi-agent modelization. The objective of this strategy is to work on the duration of the traffic lights to regulate traffic for transport modes that include private and public transport vehicles, principally the bus. The model respects the method of bus regulation with a...

Multi-party communications taking place within organizations lead to different interaction modes such as (in)direct communication
between roles, (in)direct communication restricted to a group, etc. Fully normative organisations need to regulate and control
those modes as they do for agents’ behaviors. However, this problem is not well addressed in...
Multi-agent-based simulation (MABS) is used to understand complex real life processes and to experiment several scenarios in order to reproduce, understand and evaluate these processes. A crucial point in the design of a multi-agent-based simulation is the choice of a scheduling policy. In classical multi-agent-based simulation frameworks, a pitfal...

The multiagent paradigm is well suited to designing trans-portation applications. However, when implementing such applications in highly dynamic environments, it is very costly to use languages relying on channel-based communication. Data driven coordination languages rely on a shared space in which agents add, read and retrieve data. They are intu...

We compare a simple rule based approach to a Monte-Carlo method to reach this objective. When allocated enough time, the Monte-Carlo method gives better results. If the passengers arrivals and the bus travel times are known, the bes...

Many companies aim to use Web services to integrate heterogeneous and/or remote applications in SOA (Service Oriented Architecture) contexts. We noticed the code of the Web service is monolithic, mixing concerns, and difficult to maintain. On top of all, any change requires to re deploy the modified Web service. Business rules are very often spread...

When allocated enough time, the Monte-Carlo method gives better results. If the passengers arrivals and the bus travel times are known, the best algorithm is n...
This paper presents an environment-centered approach to design multi-agent solutions to transportation problems. Based on the property-based coordination principle (PbC), the objective of our approach is to solve three recurrent issues in the design of these solutions: the knowledge problem, the space-time dimension and the dynamics of the real env...
Recent research on multi-party communications shows how multi-agent communications can take advantage of the complexity of
the human communication process. The salient point is the very nature of the communication channels which enable humans to
focus their attention on ambient communications, as well as to direct their own communications. For mult...

In this paper, we propose a multi-agent approach to solve a hard combinatorial problem: the vehicle routing problem with time win-dows. A multi-agent approach is most relevant when dealing with the dynamic version of the problem, where all the customers are not known before the start of the solving process. We focus on both the interac-tion process...

Multi-party communications enhance this model, by taking into account all the roles an agent can have in a communicatio...
When designing agent-based simulation, the choice of a coordination model is a key issue, since one of the difficulties is to link the activation of the agents with their context efficiently. Current solutions separate the activation phase from the action phase of the agents, and each action phase is based on local agent context analysis which is t...
