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…
Optimal harvesting policy for biological resources with uncertain heterogeneity for application in fisheries management
Hidekazu Yoshioka
Conventional harvesting problems for natural resources often assume physiological homogeneity of the body length/weight among individuals. However, such assumptions generally are n…
Impulsive fishery resource transporting strategies based on an open-ended stochastic growth model having a latent variable
Hidekazu Yoshioka, Tomomi Tanaka, Futoshi Aranishi +2
In inland fisheries, transporting fishery resource individuals from a habitat to spatially apart habitat(s) has recently been considered for fisheries stock management in the natur…
A simple model on streamflow management with a dynamic risk measure
Hidekazu Yoshioka, Yumi Yoshioka
We present an exactly-solvable risk-minimizing stochastic differential game for flood management in rivers. The streamflow dynamics follow stochastic differential equations driven…
A generalized stochastic control problem of bounded noise process under ambiguity arising in biological management
H. Yoshioka, M. Tsujimura
The objectives and contributions of this paper are mathematical and numerical analyses of a stochastic control problem of bounded population dynamics under ambiguity, an important…
Mathematical and computational approaches for stochastic control of river environment and ecology: from fisheries viewpoint
Hidekazu Yoshioka
We present a modern stochastic control framework for dynamic optimization of river environment and ecology. We focus on a fisheries problem in Japan, and show several examples of s…
