This paper presents a new agent-based financial market. It is designed to be both simple enough to gain insights into the nature and structure of what is going on at both the agent and macro levels, but remain rich enough to allow for many interesting evolutionary experiments. The model is driven by heterogeneous agents who put varying weights on past information as they design portfolio strate...

The successful integration and acceptance of many multi-agent systems into daily lives crucially depends on the ability to develop effective policies for adjustable autonomy. Adjustable autonomy encompasses the strategies by which an agent selects the appropriate entity (itself, a human user, or another agent) to make a decision at key moments when an action is required. We present two formulat...

This paper aim to present a multi-agent model for a simulation system, whose goal is to help one specific participant of multi-criteria group decision mak-

Multi-agent simulation provides a way to explore results from social studies and provide hints on how these results scale. One particular class of studies that is interesting to explore are economicrelated studies. We developed a multi-agent system that simulates an investment game and incorporates the results from economic-related social studies into the design of the agents. We analyzed how s...

Artifacts have been recently proposed as first-class abstractions to model and engineer general-purpose computational environments for multiagent systems. In this paper, we consider the design and development of an infrastructure called CArtAgO, directly supporting the artifact notion for the engineering of multiagent applications. We first propose an abstract model of the infrastructure, and t...

When developping multi-agent systems (MAS) or models in the context of agent-based simulation (ABS), the tuning of the model constitutes a crucial step of the design process. Indeed, agent-based models are generally characterized by lots of parameters, which together determine the global dynamics of the system. Moreover, small changes made to a single parameter sometimes lead to a radical modif...

An argumentation system can undergo changes (addition or removal of arguments/interactions), particularly in multiagent systems. In this paper, we are interested in dynamics of abstract bipolar argumentation systems, i.e. argumentation systems using two kinds of interaction: attacks and supports. We propose change characterizations that use and extend previous results defined in the case of Dun...

Total System Assurance (TSA) deals with assuring the security of all system components by considering all potential risks. This comprehensive approach to system assurance tackles security from multiple points of views, thus ensuring the highest possible level of assurance. In this paper we illustrate the TSA approach by considering a complex system running a mobile agent-based wireless sensor n...
