Decentralized Autonomous Systems

Our society is considered a decentralized autonomous system. In a centralized system, a central controller controls the entire system. In contrast, the individual components in a decentralized autonomous system behave independently, to some extent. For example, people within a given company individually make decisions, but behave in a coordinated way as a company. A city is not a living thing but changes like a living thing depending on the decision making of its components (people). We take a model-based approach and use multi-agent simulation techniques for better understanding such decentralized autonomous systems and for developing useful methods for our future society.

1. Decentralized Autonomous Smart Grid: i-Rene

Since the industrial revolution, fossil fuels have been of the main source of energy in our society. However, fossil fuels will disappear from our world in the future. It is important to make use of the renewable energies including solar, wind, and water power to overcome this crisis. We have to change our power grid into a decentralized power network to make effective use of such renewable energies. We proposed a decentralized autonomous smart grid, named i-Rene. We are studying this system from the viewpoint of intelligent system, economics, game theory, and control theory in order to develop and evaluate such a new power grid.

2. Emergence of Communication and Role-differentiation

When people gather with others, they form an organization and/or a community. They can differentiate their roles and effectively collaborate as a complete system. We develop computational models that help with the emergence of communication and role-differentiation in order to better understand adaptive behaviors and collective intelligence of humans.
