An optimal control problem in economics

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1991
The first problem in the economics of natural resources is to find the rate at which to extract the resource in order to optimize its value when there are no extraction costs. It is shown that the existence of an optimal extraction path is not guaranteed

Fractal variational principle for an optimal control problem

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2022
The optimal control of a system governed by an elliptic equation has been widely applied in engineering, and it requires twice differentiability. Furthermore, the optimal control cannot effectively deal with unsmooth boundaries.

Optimal Reinsurance Problem under Fixed Cost and Exponential Preferences

open access: yesMathematics, 2021
We investigate an optimal reinsurance problem for an insurance company taking into account subscription costs: that is, a constant fixed cost is paid when the reinsurance contract is signed.

Delta-nabla optimal control problems [PDF]

open access: yesJournal of Vibration and Control, 2010
We present a unified treatment to control problems on an arbitrary time scale by introducing the study of forward-backward optimal control problems. Necessary optimality conditions for delta-nabla isoperimetric problems are proved, and previous results in the literature are obtained as particular cases. As an application of the results of the paper we

Sustainable Optimal Control for Switched Pollution-Control Problem with Random Duration

open access: yesEntropy, 2023
Considering the uncertainty of game duration and periodic seasonal fluctuation, an n-player switched pollution-control differential game is modeled to investigate a sustainable and adaptive strategy for players.

Optimal control problem for 3D micropolar fluid equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2020
In this paper we study an optimal control problem related to strong solutions of 3D micropolar fluid equations. We deduce the existence of a global optimal solution with distributed control and, using a Lagrange multipliers theorem, we derive first-order

Optimal Transportation Problem by Stochastic Optimal Control [PDF]

open access: yesSIAM Journal on Control and Optimization, 2008
We address an optimal mass transportation problem by means of optimal stochastic control. We consider a stochastic control problem which is a natural extension of the Monge-Kantorovich problem. Using a vanishing viscosity argument we provide a probabilistic proof of two fundamental results in mass transportation: the Kantorovich duality and the graph ...

Fuzzy Optimal Control Problem of Several Variables

open access: yesAdvances in Mathematical Physics, 2019
The purpose of this paper is to establish the necessary conditions for a fuzzy optimal control problem of several variables. Also, we define fuzzy optimal control problems involving isoperimetric constraints and higher order differential equations. Then,
