In this report, we present MadKit (multi-agent development kit), a generic multi-agent platform. This toolkit is based on a organizational model. It uses concepts of groups and roles for agents to manage different agent models and multi-agent systems at the same time, while keeping a global structure. We discuss the architecture of MadKit, based on a minimalist agent kernel decoupled from speci...

Open Multi-Agent Systems (MAS) are formed by autonomous and heterogeneous agents that may pursue different and even conflicting goals. Therefore, no assumption can be a priori made about their behaviours. Thus, it is needed to constrain the potential excesses of agent autonomous behaviour by means of regulation of agent interaction. Because of this, “social” notions, such as organizations, inst...

A simple model of a portfolio allocation between mature and emerging markets is specified. The representative-agent, rational expectations version of the model has an unlimited number of equilibria, providing no reason to expect that heterogeneous agents would all coordinate on one or another equilibrium. Therefore, the model is simulated with heterogeneous expectations based on ex post returns...

We consider an asset-pricing model with wealth dynamics in a market populated by heterogeneous agents. By assuming that all agents belonging to the same group agree to share their wealth whenever an agent joins the group or leaves it , we develop an adaptive model which characterizes the evolution of wealth distribution when agents switch between different trading strategies. Two groups with he...

The paper presents an agent-based model for the explicit representation of groups of pedestrians in a crowd. The model is the result of a multidisciplinary research (CRYSTALS project) where multicultural dynamics and spatial and sociocultural relationships among individuals are considered as first class elements for the simulation of crowd of pilgrims taking to the annual pilgrimage towards Mak...

We use an analytically tractable heterogeneous-agent (HANK) version of the standard New Keynesian model to show how size fiscal multipliers depends on i) distribution factor incomes, and ii) source nominal rigidities. With sticky prices but flexible wages, representative-agent (RANK) predicts large because profits fall after a stimulus resulting negative income effect makes representative worke...

In this study, we discuss our experience in applying an open agent system to solve computing problems found in the field of High Energy Physics (HEP). Specifically, through the use of agent technologies, we have taken a grid computing and multi-agent system approach in helping physicists do their work of analysing HEP experiments. HEP analysis is characterised by high demand for computer resour...

A new age of heterogeneous resource integration has begun. Next generation of integration systems will utilize different methods and techniques to achieve the vision of ubiquitous knowledge: Semantic Web and Web Services, Agent Technologies and Mobility. In this paper we overview the approach to heterogeneous resources integration base on OntoShell concept and Semantic Webenabled integration en...

with regard to the society’s need for complicated software and high level of expenses on its development, it is necessary to take all stakeholders’ requirements and the demands into consideration, before any investments and put on the design and utilization stages. software architecture is a technical description of a software system that indicates components and their relationships between the...
