Multiagent Systems (MASs) have evolved towards the specification of global constraints that heterogeneous and autonomous agents are supposed to follow when concerning open systems A subset of these constraints is known as the MAS organisation This article describes a set of computational tools that supports the development and the programming of such systems At the system level, a middleware is provided which ensures that all agents will follow the organisational constraints At the agent level, the AgentSpeak language is extended, using Jason features, so that the agents can perceive and act upon the organisation to which they belong

Developing organised multiagent systems using the MOISE + model: programming issues at the system and agent levels

The social and organisational aspects of agency have led to a good amount of theoretical work in terms of formal models and theories However, the conception and engineering of proper organisational infrastructures embodying such models and theories are still an open issue The introduction of normative concerns with requirements of openness and adaptation stresses this issue The corresponding mechanisms for the current infrastructures appear to be not appropriate for managing distributed and open normative organisations There is still the need of proper abstractions and tools to facilitate application agents taking part in the monitoring of the organisation on one hand, and in the adaptation and definition of the organisation in which they are situated on the other hand In this paper we present and discuss ORA4MAS (Organisational Artifacts for Multi-Agent Systems), a proposed approach aiming at these issues Based on the Agents and Artifacts meta-model (A&A), it introduces organisational artifacts as first class entities to instrument the organisation for supporting agents activities within it

Instrumenting multi-agent organisations with organisational artifacts and agents

Understanding Agent Systems.

In the last years, social and organizational aspects of agency have become a major issue in multi-agent systems' research. Recent applications of MAS enforce the need of using such aspects in order to ensure some social order within these systems. However, there is still a lack of comprehensive views of the diverse concepts, models and approaches related to agents' organizations. Moreover, most designers have doubts about how to put these concepts in practice, i.e., how to program them. In this paper we focus on and discuss about the literature on formal, top-down and pre-existent organizations by stressing the different aspects that may be considered to program them. Finally, we present some challenges for future research considering particularly the openness feature of those agents' organizations.

Organization oriented programming from closed to open organizations

Cloud computing and Internet of Things (IoT) are computing technologies that provide services to consumers and businesses, allowing organizations to become more agile and flexible. Therefore, ensuring quality of service (QoS) through service-level agreements (SLAs) for such cloud-based services is crucial for both the service providers and service consumers. As SLAs are critical for cloud deployments and wider adoption of cloud services, the management of SLAs in cloud and IoT has thus become an important and essential aspect. This paper investigates the existing research on the management of SLAs in IoT applications that are based on cloud services. For this purpose, a systematic mapping study (a well-defined method) is conducted to identify the published research results that are relevant to SLAs. This paper identifies 328 primary studies and categorizes them into seven main technical classifications: SLA management, SLA definition, SLA modeling, SLA negotiation, SLA monitoring, SLA violation and trustworthiness, and SLA evolution. This paper also summarizes the research types, research contributions, and demographic information in these studies. The evaluation of the results shows that most of the approaches for managing SLAs are applied in academic or controlled experiments with limited industrial settings rather than in real industrial environments. Many studies focus on proposal models and methods to manage SLAs, and there is a lack of focus on the evolution perspective and a lack of adequate tool support to facilitate practitioners in their SLA management activities. Moreover, the scarce number of studies focusing on concrete metrics for qualitative or quantitative assessment of QoS in SLAs urges the need for in-depth research on metrics definition and measurements for SLAs.

MoiseInst: An Organizational Model for Specifying Rights and Duties of Autonomous Agents

In interactive multimedia applications, the objects composing the scene are increasingly considered as autonomous agents. Although autonomy brings ∞exibility and realism in the animation, these objects needs to be controlled. In this paper we present an organizational modelMoise Inst aiming at specifying the rights and duties of agents in society according to four points of view: structural, functional, contextual and normative. We show how this model is used within an application of interactive TV game show where avatars are represented as agents. This work was supported by an European project called Jules Verne under ITEA program.

MOISE_Inst: An Organizational Model for Specifying Rights and Duties of Autonomous Agents

In the last years, social and organizational aspects of agency have be- come a major issue in multi-agent systems' research. Recent applications of MAS enforce the need of using these aspects in order to ensure some social order within these systems. Tools to control and regulate the overall functioning of the system are needed in order to enforce global laws on the autonomous agents operating in it. This paper presents a normative organization system composed of a nor- mative organization modeling language MOISE Inst used to define the norma- tive organization of a MAS, accompanied with SYNAI, a normative organization implementation architecture which is itself regulated with an explicit normative organization specification.

Normative Multi-Agent Organizations: Modeling, Support and Control, Draft Version

In today’s world, where most of the critical infrastructures (CI) are based on distributed systems, security failures have become very common, even within large corporations. The critical infrastructures are tightly interconnected, mutually dependent, and are exposed everyday to new risks.These (inter)dependencies generate potential cascading effects that may spread a malfunction or an attack from one part of the system to another dependent infrastructure.In this paper, we propose a risk-based methodology that aims to monitor interdependent services based on generic risks and assurance levels using the classical security properties: Confidentiality, Integrity and Availability. This allows each CI owner to monitor, react and adopt the best behavior corresponding to the security status of its different services.

Risk-Based Methodology for Real-Time Security Monitoring of Interdependent Services in Critical Infrastructures

Interactive multimedia applications are whelming to increase realism in their content and scenes with which users interact. To this aim, autonomous agents are increasingly used to implement the objects composing the scene. Although autonomy brings flexibility and realism in the animation, it has to be controlled in order to conform to the global behaviour targeted by the designer of the application. Multi-agent based organisational models are good candidates to specify "rights" and "duties" of agents with respect to the intended behaviour. In this paper we present $\mathcal{M}\textsc{oise}^{Inst}$, a meta-model aiming at representing normative organisations of agents according to four points of view: structural, functional, contextual and normative. We show how this model is suited to control an application of interactive TV game show where avatars are based on agents.
