The presence of chemical industry in urban area represents a very high technological risk. That is the reson the installation of alert’s sirens to prevent population from danger when an incident happens is became necessary. This installation should have some means which are sufficiently reliable in order to permit the detection of incident in an adequate time. The industrial site survey that pe...

We present PARKAGENT, an agent-based, spatially explicit, model for parking in the city. PARKAGENT is based on the geosimulation approach, combining real-world GIS database with a multi-agent system. The model simulates the behavior of each driver in a spatially explicit environment and is able to capture the complex self-organizing dynamics of a large collective of parking agents within a non-...

Article history: Received 29 January 2008 Received in revised form 10 April 2008 Accepted 12 April 2008 This paper presents the concept and theoretical specification of a multi-agent based model for spatio-temporal simulation of a coupled human–landscape system. The model falls into the class of all agents, where the human population and the landscape environment are all self-organized interact...

We have explored mechanisms for converting organizations to an edge type organization. Beyond structural differences, organizations differ in information flow network and information sharing strategies. We review organizational adaptation. A model of computational organization and reorganization is presented using dynamic roles. In addition to self-organization, our model allows human oversight...

We describe several principles for designing Actor-Agent Communities (AAC) as collectives of autonomous problem solving entities (software agents and human experts) that self-organize and collaborate at solving complex problems. One of the main distinctive aspects of the AAC is their ability to integrate in a meaningful way the expertise and reasoning of humans with different information proces...

Background/Introduction: The Zipf’s law establishes that if the words of a (large) text are ordered by decreasing frequency, the frequency versus the rank decreases as a power law with exponent close to -1. Previous work has stressed that this pattern arises from a conflict of interests of the participants of communication: speakers and hearers. • Methods: The challenge here is to define a comp...

We have developed computer environments that support learning by teaching, concept mapping, scaffolding, and the use of self regulated learning (SRL) skills by social interactions with virtual agents. More specifically, students teach a computer agent, Betty, and can monitor her progress by asking her questions and getting her to take quizzes. The system provides SRL support via dialog-embedded...

In this paper, we present a coordination approach to resource allocation problem in multiagent systems. Agents adaptively coordinate resources among themselves to handle resource shortage crises resulted from events they encounter in dynamic, uncertain, real-time, and noisy environments. The coordination approach is implemented with a hybrid negotiation mechanism. The hybrid negotiation mechani...

Distributed management of complex large-scale infrastructures, such as power distribution systems, is challenging. Sustainability of these systems can be achieved by enabling stabilisation in global resource utilisation. This paper proposes EPOS, the Energy Plan Overlay Self-stabilisation system, for this purpose. EPOS is an agent-based approach that performs self-stabilisation over a tree over...
