Access control is a main security issue in the management of complex information systems as well as Multi-agent Systems (MAS). In this paper we discuss the application of the Role-Based Access Control (RBAC) model in the context of TuCSoN coordination infrastructure for MAS. RBAC models and their extensions are currently considered the most effective approach for engineering access control in c...

This paper presents a kind of application of the software performance engineering to the area of agent-based systems. In a first part we will describe the general aspects and contents of multi agent systems (MAS) architectures. Then, a short presentation of the main software performance principles should motivate the measurement approaches for the MAS. Software agents can be intelligent as well...

However, the development of complex software systems by using the agent-oriented approach requires suitable agentoriented modelling techniques and methodologies which provide explicit support for the key abstractions of the agent paradigm. Several methodologies supporting analysis, design and implementation of Multi-Agent Systems (MAS) have been proposed in the context of Agent Oriented Softwar...

In this paper, we pursue a modelling approach to address security requirements for multi-agent systems (MAS). This will allow developers to account for both the system and agent-specific security requirements of a MAS during the requirements phase and throughout the whole Software Development Lifecycle of the system. We focus on autonomy, mobility and cooperation of individual agents and how th...

It is recognized that knowledge has a considerable usefulness in people's daily life and all businesses. The current paper discusses a knowledge description using ontology and its application in Multi Agent Systems (MAS). The presented work proposes to reach a powerful relationship between MAS and Knowledge Management (KM), principally by introducing results achieved in the semantic web domain ...

Several recent design techniques address the problem of distributed controller synthesis for multi-agent systems (MAS). However, since these methods use a decomposition based approach to reduce the complexity of the MAS, they cannot provide a guarantee of performance with the designed controller, and furthermore lead to conservative designs due to the Lyapunov shaping paradigm. This paper propo...

An important subset of multi-agent systems (MAS) are based on organizational models. These models try to define pre-defined intended agent interaction patterns. Given an application domain, however, the choice of a particular organizational model that better solves the problem is still an open problem. In order to guide this choice, a MAS developer must have the opportunity to test distinct org...

Agent-based computing is a new paradigm to build complex distributed computer systems. The article explores one of the key issues of agent-based computing the problem of interactions in multi-agent systems (MAS) in dynamic organizational context. Particularly, the article describes an approach to the problem of coalition forming based on fuzzy coalition games with associated core, as well as fu...

In this paper some results achieved in the domain of multi-agent methodology applied to educational systems are presented. We have developed a distance learning environment based on a two-level multi-agent architecture. Two-levels are distinguished since the application is composed by two multi-agent systems (MAS). The higher-level MAS is composed of cognitive agents, which provide the main fun...

The GRID and MAS (Multi-Agent Systems) communities believe in the potential of GRID and MAS to enhance each other as these models have developed significant complementarities. Thus, both communities agree on the ’what’ to do: promote an integration of GRID and MAS models. However, while the ’why’ to do it has been stated and assessed, the ’how’ to do it remains a research problem. This paper ad...
