【Abstract】 We study an optimal harvesting problem for a class of Logistic population with time lag. The exact controllability is analyzed,existence of optimal control is demonstrated by means of maximizing sequence and Mazur’s theorem,and a maximum principle is derived out via Dubovitskii-Milyutin theory .更多还原
