In this research, we apply a control engineering approach to the game theoretical framework that models human and organizational decision making. This research aims to develop a control theoretical mechanism design method that achieves the desired Nash equilibrium. For example, if the game model can describe a situation where multiple players make competitive decisions (gut-searching), we can find the necessary incentives to change to the desired equilibrium state and present rewards such as institutional design and negotiation. We have realized equilibrium control and belief estimation methods using algorithms based on feedback control systems for standard games, which are often used in prisoner's dilemmas, and Bayesian games, which can handle uncertainty in decision making.

Furthermore, to make human behavioral predictions more human, we need to focus on the irrational aspects of humans. We are also working on a decisional model with irrationality based on an emotional model and design problems based on that model. These results will lead to the development of robots and AI (game player) algorithms for human-like decision-making in the future.

Thus, we are discussing the development of theoretical tools to analyze and design the decision-making field of human beings and organizations, and the sustainable cyber-physical human system from the viewpoint of control engineering (especially, design theory).
