Como trabalhos futuros, existem atividades a serem realizadas para dar continuidade ao desenvolvimento do modelo. Entre os quais pode-se citar:

• Pesquisar a possibilidade de incluir estruturas que possibilitem a definição mais de-talhada das interações entre agentes e ambiente (agente-agente e agente-ambiente) utilizando escopos espaciais;

• Pesquisar a viabilidade e implicações de utilizar objetos normativos para distribuir planos normativos para atingir objetivos locais e outras opções para obtenção de novos planos (e.g. troca de planos (ANCONA et al., 2004)).

• Implementar e disponibilizar o modelo para que outros pesquisadores possam testar, para verificar através do uso em simulações as necessidades de evolução do modelo.

• Analisar questões associadas ao uso do modelo. Uma destas questões é sobre o fato de ter diversas normas distribuídas em escopos espaciais diferentes podendo resultar em diferentes reputações de um único agente no ambiente, levando a uma noção de localidade da reputação.

Através dos estudos de caso, foi possível verificar que o uso das abstrações fornecidas facilita a inserção de normas e outras estruturas no cenário. Dando continuidade ao modelo e visando a elaboração de cenários mais sofisticados, seriam necessários a in-serção de outras estruturas e abstrações, tais como as existentes em (LOPEZ; LUCK;

D’INVERNO, 2007), para inserir objetivos normativos e também seriam interessantes inserir outros protocolos que descrevam tarefas, tais como os existentes em (DIGNUM;

VÁZQUEZ-SALCEDA; DIGNUM, 2005).

Outro aspecto interessante é que os agentes sendo condicionados na possibilidade de perceber a existência de um objeto normativo, o raciocínio normativo requerido pelos agentes que lidam com objetos normativos deverá ser de natureza não-monotônica. Além disso, o raciocínio normativo relacionado com a possibilidade de criar espaços normativos no ambiente, cada um com seu próprio propósito organizacional e estrutura normativa, nos leva a várias possibilidades que deverão ser analisadas no futuro.

Outras questões que não foram abordadas neste trabalho, também necessitariam de maior estudo posterior, tal como o cruzamento de informações das diferentes entidades multiagentes envolvidas para auxiliar no desenvolvimento da aplicação. Uma das possibi-lidades seria a verificação dos tipos de papéis relativos relacionados a um espaço norma-tivo e os papéis da organização presente no local, pois a verificação da consistência destes papéis atualmente fica a cargo do projetista da simulação. Outra verificação possível seria a consistência de missões com os espaços relacionados e os recursos necessários. Além disso, o aspecto da interação dos agentes, tais como protocolos e linguagens para inte-ração, não é tratado explicitamente pelo modelo, sendo possível defini-lo implicitamente nos agentes ou através de normas, porém a definição explícita poderia trazer benefícios, o que poderá ser estudado em trabalhos futuros.
