Multi-agent systems (MAS) are widely acknowledged as an appropriate modelling paradigm for distributed and decentralized systems, where a (potentially large) number of agents interact in non-trivial ways. Such interactions are often modelled defining high-level interaction protocols. Open MAS typically benefit from a number of infrastructural components that enable agents to discover their peer...

There has been a great interest in using multiagent systems (MAS) in a wide variety of applications in recent years, especially Webbased applications such as those in the field of electronic commerce. Agent-oriented methodologies, development environment and tools have become a priority for the development of large-scale agent-based systems. The work we present here belongs to the disciplines o...

The eld of agent oriented programming (AOP) recently emerged from its object{ oriented roots. Whereas the beneets of object{orientation nowadays are widely used in AOP, modeling of communication in multi{agent systems (MAS) still lacks adequate abstractions. Currently considered approaches like RM{ODP, CORBA, or languages like Java introduce object{orientation to inter{agent communication while...

To achieve high quality and efficiency standards, interoperability between different information systems in healthcare is strongly required. Distribution, high modularity, robustness are features of agent oriented architectures, making MultiAgent Systems (MAS) ideal for Health Information Systems (HIS), as the healthcare domain is characterized by system and data heterogeneity. This paper prese...

Multi-Agent Systems (MAS) in health-care domains are showing a rapid increase, in order to manage complex tasks and adapt gracefully to unexpected events. On the other hand, the lack of well-established agentoriented engineering methodologies to transform knowledge level descriptions into deployable agent systems slackens MAS development. This paper presents a new methodology in modelling and a...

Multi-agent systems models are frequently in many complex real systems. They allow expressing event-based multi-agent, providing environment, and messaging, execution and sensor services. The development of agent based applications is difficult suffering from insufficient standards and tools and on the other hand deployment issues are little researched and supported. The cooperation in multi-ag...

Multi Agent Systems (MASs) are undergoing a transition from closed monolithic architectures into open architectures composed of a huge number of autonomous agents. Large-scale MASs involve hundreds or perhaps thousands of agents to share a common goal. However, the current practice of MAS design tends to be limited to individual agents and small face-to-face groups of agents. With this kind of ...

A prolific number of different Multi-Agent Systems (MAS) and associated applications have been developed in numerous research institutes and industrial laboratories world-wide. Perhaps the most important barrier to MAS making a successful transition from this research environment towards widespread adoption for consumer products and businesses, is the lack of interoperability between heterogene...

Based on common functionality existing among different multi-agent systems (MAS) such as reactivity, deliberation and communication, several tools have been built to develop MAS. Despite these efforts, most of them are targeted to specific application domains or specific types of agents, limiting thus their applicability. This paper describes an approach to develop MAS that aims at providing fl...
