【Abstract】 In this paper, we investigate the well posedness and the optimal harvesting problem for a class of nonlinear time-dependent population system with diffusion. Both existence and uniqueness of a positive solution are proven using the fixed point theorem. Existence of the optimal harvesting rate control is given, and the necessary condition for optimality and the uniqueness of the optimal control is obtained.更多还原
