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…
Tractable fish growth models considering individual differences with an application to the fish Plecoglossus altivelis altivelis
H. Yoshioka, Y. Yoshioka, M. Tsujimura
Modeling fish growth is an important research topic in ecological and fishery sciences because body weight statistics directly affect the total biomass of fish in a habitat, which…
