Agent Coordination Contexts for the formal specification and enactment of coordination and security policies

Andrea Omicini, Alessandro Ricci, Mirko Viroli
2006 Science of Computer Programming  
In the context of multi-agent systems (MAS), an Agent Coordination Context (ACC) is an abstraction provided by the infrastructure to each agent entering a MAS, aimed at enabling and controlling all the  ...  In particular, in this paper we exploit typical process algebra techniques to define the syntax and semantics of a language for ACC specification, describing patterns of interaction protocols allowed to  ...  A Coordination Network for Agentbased Computing".  ...

RBAC for Organisation and Security in an Agent Coordination Infrastructure

Andrea Omicini, Alessandro Ricci, Mirko Viroli
2005 Electronical Notes in Theoretical Computer Science  
This trend is evident in the state-of-the-art models adopted for the management of security and organisation of complex information systems: in this context Role-Based Access Control (RBAC) models are  ...  In this paper we discuss how an RBAC-like model has been fruitfully exploited to extend an infrastructure for the coordination of agent-based systems -TuCSoN -with the support for organisation and security  ...  Conclusion In this paper we introduced the RBAC model for engineering some security and organisation aspects in the context of MAS.  ...

Environment-Based Coordination Through Coordination Artifacts [chapter]

Alessandro Ricci, Mirko Viroli, Andrea Omicini
2005 Lecture Notes in Computer Science  
In the context of human organisations, environment plays a fundamental role for supporting cooperative work and, more generally, complex coordination activities.  ...  In this work we describe this framework, by defining a model for the coordination artifact abstraction, and discussing the infrastructures and technologies currently available for engineering MAS application  ...  Organisational models based on the notion of role are pervasive in computer science as well as in the context of human organisation theories, impacting also on security and coordination aspects; role-based  ...

On the Role of Simulation in the Engineering of Self-Organising Systems: Detecting Abnormal Behaviour in MAS

Luca Gardelli, Mirko Viroli, Andrea Omicini
2005 Workshop From Objects to Agents  
This is based on the TuCSoN infrastructure, which provides agents with an environment of artefacts-most notably coordination artefacts and agent coordination contexts.  ...  In particular, we evaluate the use of simulations of high-level system models to analyse properties of a design, which can anticipate the detection of wrong design choices and the tuning of system parameters  ...  For the methodology, we relied on formal simulation and modelling via stochastic π-calculus, which-even though is a quite new language in the context of the MAS communityshowed its effectiveness as a design  ...

RAMASD: a semi-automatic method for designing agent organisations This work has been supported by BT under a grant from the office of the Chief Technologist (No. ML816801/MH354166)

ANTHONY KARAGEORGOS, NIKOLAY MEHANDJIEV, SIMON THOMPSON
2002 Knowledge engineering review (Print)  
Roles and their interactions in a particular context form role models.  ...  In Section 4 we present the role algebra, a formal model of role relations which is the main enabler of our approach. We define its semantics using a two-sorted algebra.  ...  Role algebra: a formal model of role relations Designing an agent organisation in our method refers to allocating roles to agents.  ...
