The paper aims to present a river basin modeling using GAMA platform for water resources analysis. Currently, several models based on multi-agent systems are used for natural resources management and they present satisfactory results for this type of scenario. GAMA is agents based and widely used in this context with several studies already published. In this study, the Sa ̃o Gonc ̧alo and Lagoa Mirim basins were considered from georeferenced data. In the modeling, regions, and rivers are agents on the system where rivers water can flow among neighbors regions.
Este artigo introduz um modelo de percepção fuzzy para agentes BDI, com uma aplicação em uma versão fuzzy do problema presa-predador, onde o processo de decidir qual presa um predador deve atacar, com base na comparação de sua força com a da presa, é baseado em seu mecanismo de percepção fuzzy. Neste ambiente de informação imperfeita, consideram-se três tipos de predadores, um deles sendo o agente BDI com percepção fuzzy. Várias simulações foram realizadas para a análise comparativa dos comportamentos dos diferentes agentes predadores em dois tipos de ambientes: com ou sem competição entre predadores.
Piaget's theory of social exchanges has been used as the basis for the analysis of interactions in Multiagent Systems, allowing the modeling of interactions as services exchange processes between pairs of agents, followed by the evaluation of those services by the agents involved, producing the so-called social exchange values. The purpose of this work is to develop a BDIFuzzy agent model for the Jason platform, with abilities to assess qualitatively, subjectively the social exchanges values originated in the provision and in the receipt of non-economic services, based on Piaget's theory of social exchanges. An application to the simulation of exchange processes in a social organization, namely, the urban vegetable garden San Jerónimo (Seville, Spain) is presented.
O presente artigo tem como objetivo apresentar o estudo das áreas de gerenciamento de recursos hı́dricos, sistemas multiagente (SMA) e jogos de papéis, bem como a integração destas à modelagem inicial de gestão participativa dos atores (agentes) envolvidos neste estudo de caso. Neste contexto, utilizou-se a abordagem ComMod considerando a bacia hidrográfica do São Gonçalo e da Lagoa Mirim. A modelagem foi realizada utilizando o diagrama de integração, que representa a visão geral do problema, e os diagramas UML (classe e sequência), que expõem a formalização das ações e as interações entre os agentes do sistema. Como resultado, obteve-se as ações dos agentes e suas interações com o sistema. Por trabalhos futuros, pretende-se avaliar ferramentas e desenvolver o jogo computacional baseado em agentes.
