Environmental management and restoration under unified risk and uncertainty using robustified dynamic Orlicz risk
Hidekazu Yoshioka, Motoh Tsujimura, Futoshi Aranishi +1
Environmental management and restoration should be designed such that the risk and uncertainty owing to nonlinear stochastic systems can be successfully addressed. We apply the rob…
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…
The Robust Orlicz Risk with an Application to the Green Photovoltaic Power Generation
H. Yoshioka, M. Tsujimura
We propose a novel recursive utility for controlling stochastic processes under risk and uncertainty. Our formulation uses a robustified Orlicz risk that can evaluate risk and unce…
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…
