Implementing and deploying a complete multi-agent system in whatever domain, especially those that are inherently complex and dynamic, is undoubtedly a very hard and time-consuming task. This paper analyzes the adequacy of traditional approaches in the field of Agent-Oriented Software Engineering to create adequate multi-agent systems applicable to the(More)
Traffic control through semaphores, the so-called traffic lights, is an important asset at hand for engineers and practitioners in charge of managing large-scale urban networks. Optimization of traffic flow through city arteries depends highly on the way traffic lights are coordinated, and making them sort of intelligent in some way seems to be an excellent(More)
Future Urban Transport (FUT) describes all desired features that are currently being envisaged within the umbrella of Intelligent Transportation Systems. With advances in computer and communication technology, elevating thus the user to a central concern rather than favoring performance only, both the scientific community and practitioners are in search for(More)
The concept of intelligent transportation has been devised about a couple of decades ago and still presents many challenging issues to be addressed so as it can be implemented to its full potential. In this paper we emphasise characteristics such as being user-centred and service oriented to support an important facet of future urban transportation: being(More)
Diagnosing unwanted behaviour in Multi-Agent Systems (MASs) is a crucial task to assure the correct operation of a system. A light-weight technique inspired by the software-engineeringoriented techniques, the we have coined Extended Spectrum-based Fault Localisation for Multi-Agent Systems (ESFL-MAS) can be used to shorten the diagnose cycle by reducing the(More)
Unmanned Aerial Vehicles (UAVs) are gaining the attention of researchers around the world. Recently researchers apply the multi-agent paradigm to such domain taking advantage of its research in cognition, deliberation, and mainly coordination mechanisms. The aim of our research is to contribute to the multiple quadcopter simulation area introducing a(More)
Inter-modal interfaces are extremely important for the transportation system as a whole. Therefore, designing and dimensioning airport terminals' curbsides are a major step to improve passengers' experience. Indeed, evaluating such design is a critical task that must be performed to point out the best solution. This paper reports on our modelling,(More)
Multi-Agent Systems (MAS) must increase their reliability in order to guarantee a solid and safe response to unexpected situations in complex domains. To address such an issue, both fault tolerance and software testing techniques are applied to ensure complying services; the foundation of these is the effectiveness in identifying and classifying fault(More)
Small-scale Unmanned Aerial Vehicles (UAVs) are gaining the attention of researchers around the world, due to their versatility and performance in both indoor and outdoor applications. The whole project aims to specify and implement a symbiotic simulation platform to assist the design, development and testing of UAVs that use a quad-rotor configuration.(More)
