This paper describes an exploratory work that aims to identify a semantic basis underlying a mental model from the field of emergency management using a collaborative approach. An experimental application of the distance ratio measure was used to compare individual networks among themselves and to analyze the aggregated network representing the group mental model. The data was obtained by surveying a group of Civil Protection graduates and aggregating all the answers (shared mental model). The data allowed us to deepen the analysis of the resulting network in order to understand the main group concepts and their relations within this domain.

Grouping agents into coalitions can be an important way of cooperation through which multi-agent systems(MAS) improve their performance, accomplish their assignments, increase their benefits, and achieve their goals. However, agents belonging to a coalition must decide how they behave to increase their gains. In this paper, we present a model that combines learning and coalition formation to enhance cooperation over the Iterated Prisoner's Dilemma (IPD). We focus on agents interacting over complex networks since they provide a realistic model of the nowadays interconnected world. Our results suggest that coalitions are a relevant contribution to achieve cooperation in the IPD.

By seeking for alternative land uses in the Amazon, we designed an Agent-Based Model (ABM) containing a set of rural practices for small-scale farmers. In order to reach a more sustainable development, we analyze the benefits and the constraints of these practices. By comparing various production activities starting from the same initial conditions, we test several strategies and their efficiency faced to different initial conditions and environmental laws. Our study does not compare solely the financial profits of the agricultural activities. But it seeks to better understand and assess the feasibility of new activities in terms of family labor management, availability of land and economic profitability. Our first results conclude that a strict compliance with the law is not economically sustainable if the farmers still apply their standard land use strategies. We hope that this model could become a useful tool for the small farmers. By easily modifying the behavior of an agent, they could virtually invent and assess the efficiency of new practices on their farm. We also hope that this tool could become a means to facilitate dialogue between different stakeholders in the Amazon, in order to achieve more sustainable development.

A participatory social simulation framework is presented to support context analysis in Uruzgan province's Baluchi Valley region, Afghanistan under the banner of context sensitivity. Working in fragile states and areas affected by armed conflict is challenging for locals, development workers and researchers alike. Meaningful interaction with locals for data collection purposes is difficult and techniques applied should balance the desire for broad and in-depth data elicitation with sound risk management. Rarely can standard solutions deliver the results needed for making informed decisions in such circumstance. The reader is shown protocols for data collection and analytics that are tailored to doing context analysis and decision support for development cooperation in areas affected by armed conflict. Select results are presented to demonstrate the usefulness of the framework. The article concludes with a comparison of the proposed framework with development cooperation requirements.

Smart grids have received great attention in recent years. Among many technologies that are used in smart grids, the concept of vehicle-to-grid (V2G) arises, which allows the use of electric vehicles' batteries to provide energy back to the grid when needed. An interesting research approach is the formation of coalitions among electric vehicles to provide electric power back to the grid, increasing the reliability and stability of the grid. In this paper, we propose a technique that uses smart grids' domain information to establish constraints on coalition formation process, promoting the pruning of the coalition structure's search space. We evaluate our approach by showing that it can drastically prune the search space, which makes coalition formation possible for a relatively higher number of agents.

This paper presents some preliminary results obtained in the modeling of a multiagent system for the simulation of the social production and management of a urban ecosystem, in particular, the project of the San Jerónimo Vegetable Garden of city of Seville, Spain. We introduce a study regarding the interactions between agent roles in this particular social organization. For that, we use Activity Diagrams of UML, which provide a clear visualization of the communication between agent roles and allow the identification of communication protocols used by the agents. Furthermore, we show an initial proposal for the encapsulation of those protocols in Cart Ago artifacts, presenting a more modular approach for agent communication in multiagent systems.

The It was modeled a market where alliances are fundamental for complementing competences and abilities. The firms need those alliances to exploiting new opportunities. The strategic enterprise behavior must affect the alliances and their intensity and fragility levels. Enterprises facing market opportunities which request strategic alliances can or cannot cooperate on the others according to their strategic behavior profiles and according to the historical cooperation evaluation of their potential partners. The model of agent-based simulation proposed for such essay, uses roles based on Sugars cape, on prisoner dilemma for n-players and concepts existents about cooperation, stakeholders and shareholders theories and enterprise alliances. It has been verified that the emergence of cooperation can occur, but depends on how fierce is the competition in terms on density and internal cost structures.

This paper describes a Fuzzy-Genetic Algorithm Approach for path planning of mobile robots with obstacle detection and avoidance in static and dynamic scenarios. Through the software Net logo, used in simulations of multiagent applications, a seminal model was developed for the given problem. The model, which contains a robot and scenarios with or without obstacles, is responsible for determining the best path used by a robot to achieve the goal state in a shorter number of steps and avoiding collisions. Additionally, a performance evaluation of this model in comparison with A* algorithm is presented.
