Abstract(s)
Modelação e simulação baseadas em agentes estão a ganhar cada vez mais importância e
adeptos devido à sua flexibilidade e potencialidade em reproduzir comportamentos e estudar
um sistema na perspetiva global ou das interações individuais.
Neste trabalho, criou-se um sistema baseado em agentes e desenvolvido em Repast Simphony
com o objectivo de analisar a difusão de um novo produto ou serviço através de uma rede de
potenciais clientes, tentando compreender, assim, como ocorre e quanto tempo demora esta
passagem de informação (inovação) com diversas topologias de rede, no contato direto entre
pessoas.
A simulação baseia-se no conceito da existencia de iniciadores, que são os primeiros
consumidores a adotar um produto quando este chega ao mercado e os seguidores, que são
os potenciais consumidores que, apesar de terem alguma predisposição para adotar um novo
produto, normalmente só o fazem depois de terem sido sujeitos a algum tipo de influência.
Com a aplicação criada, simularam-se diversas situações com a finalidade de obter e observar
os resultados gerados a partir de definições iniciais diferentes. Com os resultados gerados
pelas simulações foram criados gráficos representativos dos diversos cenários.
A finalidade prática desta aplicação, poderá ser o seu uso em sala de aula para simulação de
casos de estudo e utilização, em casos reais, como ferramenta de apoio à tomada de decisão,
das empresas.
Modeling and agent-based simulation are increasingly gaining importance and supporters due to its flexibility and capability to reproduce behaviors and study a system in the global perspective of the individual interaction. In this work, an agent-based system has been created and developed in Repast Simphony in order to analyze the diffusion of a new product or service through a network of potential customers while trying to understand how it happens and how long it takes to pass the information (innovation) among people using various network topologies, through direct contact among people. The simulation is based on the concept of the existence of starters, which are the first consumers to adopt a product when it hits the market and the followers, who are potential consumers who, despite having some predisposition to adopt a new product, usually only do it after they have been subject to some sort of influence. With the system, different situations were simulated in order to attain and observe the results generated from different initial settings. With the generated results through the simulations, graphics were created to express the results of the various scenarios. The practical purposes of this application are its use in a classroom context for simulation of case studies, and its use in real cases as a tool to support decision making in companies.
