Optimal periodic resource allocation in reactive dynamical systems: Application to microalgal production
Autor: Olivier Bernard, Liu‐Di Lu, Julien Salomon
Publikováno v: International Journal of Robust and Nonlinear Control
International Journal of Robust and Nonlinear Control, 2022, ⟨10.1002/rnc.6171⟩
In this article, we focus on a periodic resource allocation problem applied to a dynamical system which comes from a biological system. More precisely, we consider a system with $N$ resources and $N$ activities, each activity use the allocated resour

We propose a new strategy for solving by the parareal algorithm highly oscillatory ordinary differential equations which are characteristics of a six-dimensional Vlasov equation. For the coarse solvers we use reduced models, obtained from the two-sca
