Distributionally robust decision-making under ambiguity: case study of water environmental management
Hidekazu Yoshioka, Motoh Tsujimura, Yumi Yoshioka +1
Decision-making under uncertainty is ubiquitous in environmental project planning. Environmental processes such as a streamflow discharge often present a subexponential memory, whe…
Mathematical model for sustainable fisheries resource management accounting for size spectrum
Hidekazu Yoshioka, Yumi Yoshioka, Motoh Tsujimura +1
This paper proposes a novel modelling and control framework for growth models that incorporate a size spectrum in conjunction with numerical computation and extensive field surveys…
Non-exchangeable evolutionary and mean field games and their applications
H. Yoshioka, M. Tsujimura, T. Tanaka
A replicator dynamic for non-exchangeable agents in a continuous action space is formulated and its well-posedness is proven in a space of probability measures. The non-exchangeabi…
Fishery resources management
Hidekazu Yoshioka, Motoh Tsujimura, Yumi Yoshioka
We consider management of the fish species Plecoglossus altivelis altivelis, a major inland fishery resource in Japan playing important roles from economic, cultural, and recreatio…
Generalized pair-wise logit dynamic and its connection to a mean field game: theoretical and computational investigations focusing on resource management
Hidekazu Yoshioka, Motoh Tsujimura
Logit dynamics are evolution equations that describe transitions to equilibria of actions among many players. We formulate a pair-wise logit dynamic in a continuous action space wi…
A rational logit dynamic for decision-making under uncertainty: well-posedness, vanishing-noise limit, and numerical approximation
Hidekazu Yoshioka, Motoh Tsujimura, Yumi Yoshioka
The classical logit dynamic on a continuous action space for decision-making un-der uncertainty is generalized to the dynamic where the exponential function for the softmax part ha…
