In this paper, a new approach in decision making process inspired by human visual cortex has been proposed. In this approach knowledge of a group of agents (training data) will be used for decision-making. The proposed approach tries to meet two fundamental features, i.e., robustness and specificity. The hierarchical model that has been represented in this work, tries to extract the knowledge about...
The development of large-scale distributed multi-agent systems in open dynamic environments is a challenge. System behavior is often not predictable and can only be evaluated by execution. This paper proposes a framework to support design and development of such systems: a framework in which both simulation and emulation play an important role. A distributed agent platform (AgentScape) is used to...
Agent technology is a good approach for solving a number of problems concerned with personalized learning. In personal learning contexts individual students are given an environment that takes into account of their needs, interests and aspirations, and this is intended to lead to an enhanced learning experience. The aim of this paper is to show how agent systems can not only form a good framework...
Organizational mechanisms can be introduced in a multi-agent system with the aim of influencing the behavior of agents to achieve their objectives in a proper way. We propose to model organizational mechanisms by means of artifacts, which present good advantages for coordinating agents environments. We claim that artifacts, as reactive entities located into the environment of a Multi-agent System,...
In this article we describe the implementation of a diversified investment strategy using 25 intelligent agents. Each agent utilizes several data mining models and other artificial intelligence techniques to autonomously day trade an American stock. The agents were individually tested with out-of-sample data corresponding to the period between February of 2006 and June of 2010, and most achieved an...
As wireless sensor network applications grow in complexity, ad-hoc techniques are no longer adequate. Thus, it is crucial that these systems be adaptive and autonomous to remain functional in the face of unreliable communications, dead nodes, and other unexpected failures. We propose to manage sensor networks based on a rigorous multiagent organizational design, which separates application logic from...
In the course of globalization competitive pressure is rising in most industrial sectors. High quality products are basic prerequisites for companies of high wage countries to be present on the global market. Improved adherence to delivery date, increased flexibility despite to decreased production costs are some examples of the challenges to be managed just to keep current positions. In general,...
This article addresses the problem of coalition formation. Our work specially focuses on task oriented domains, where self-interested agents want to perform bundles of tasks. Depending on its resources, an agent may not be able to perform a bundle of tasks alone. Then the agent needs to find partners, interested in the same bundle, and agree to put their resources in common, in order to perform the...
Trust is generally considered an important aspect in the decision making of agents. In the literature, a variety of computational models for trust have been proposed covering how an agent can make a decision by exploiting the trust levels it has for the different options. Within such a decision making mechanism the focus is usually on a single most trusted option, which as a side effect may lead to...
Our goal is to understand limitations of simplicity of knowledge structures and reasoning processes in Multiagent Systems. Therefore, we propose a framework that integrates external storage media and a capacity-constrained Multiagent System. Agents can store knowledge internally and on external storage media located in an environment. In some cases, agents either have to forget or to store knowledge...
Service-orientation has become the leading paradigm for modern IT system design and development as service-oriented system design has great potential for improving the efficiency and quality of the IT systems. This paper presents a model-driven approach for the generic integration of service-oriented architectures (SOA) and multi-agent systems (MAS). In fact, a model transformation from SoaML - a...
