Multi-Agent Systems (MAS) provide for the modeling of practical systems in the elds of communications, exible manufacturing, and air-traac management 1]. Herein, we treat the general MAS as an Interconnected Discrete Event System (IDES). By design or due to failure, the actual system is often subject to change and so is its IDES model. For example, at the highest level, an existing subsystem ma...

Interoperability is a key issue for a wider adoption of mobile agent systems (MASs) in heterogeneous and open distributed environments where agents, in order to fulfill their tasks, must interact with non-homogeneous agents and traverse different agent platforms to access remote resources. To date, while several approaches have been proposed to deal with different aspects of MAS interoperabilit...

We present in this paper an adaptive security model for Multi-agent systems. A security meta-model has been developed in which the traditional role concept has been extended. The new concept incorporates the need of both security management as used by role-based access control (RBAC) and agent functional behaviour in agent-oriented Software Engineering (AOSE). Our approach avoids weaknesses of ...

Online Communities are an example of sociallyaware, self-organising, complex adaptive computing systems. The multi-agent systems (MAS) paradigm coordinated by self-organisation mechanisms has been used as an effective way for the simulation and modeling of such systems. In this paper, we propose a model for simulating an online health community using a situated multi-agent system approach, gove...

For sometime now agent-based and multi-agent systems (MASs) have attracted the interest of researchers far beyond traditional computer sciience and artificial intelligence (AI). In this article we try to identify focal points of interest for researchers working in 1:he area of distributed AI (DAI) and MAS as well as application-oriented researchers coming from related disciplines, e.g. electric...

Intelligent Agent technology is an important, exciting and relatively new paradigm in software design. The term intelligent agent is now used as an umbrella term representing a wide range of software with different characteristics and abilities [1]. This fact led to many definitions of intelligent agent, but the authors agree with the definition proposed by Wooldridge and Jennings [2] stating t...

The increased complexity and dynamism of present and future Multi-Agent Systems (MAS) enforce the need for considering both of their static (design-time) and the dynamic (run-time) aspects. A type of balance between the two aspects can definitely give better results related to system stability and adaptivity. MAS organization is the research area that is concerned with these issues and it is cu...

Model-driven engineering (MDE), implicitly based upon meta-model principles, is gaining more and more attention in software systems due to its inherent benefits. Its use normally improves the quality of the developed systems in terms of productivity, portability, inter-operability and maintenance. Therefore, its exploitation for the development of multi-agent systems (MAS) emerges in a natural ...

Multi-Agent Systems (MAS) have been widely proposed and applied to various application domains, where traditional approaches are impractical, such as space exploration missions. MAS can offer greater redundancy, efficiency, and scalability; however, they also raise new challenges, such as complex and often unexpected emergent group behavior, which require a formal specification as well as verif...

Introduction. Decentralization and openness are inherent properties of multiagent systems (MAS). The technologies they provide are thus the right abstraction for developing Web-oriented applications. Moreover, different works have been proposed to use Semantic Web technologies (SWT) for representing various dimensions of MAS (e.g., interaction protocols, norms, organizations). Given these facts...
