【Abstract】 This paper gives the asymptotic property of the population system with regard to an idealpopulation state on the basis of a time continuous and age discrete population evolution modelgiven in [1],and then proceeds to give the attainability and geometric property of the attaina-ble set of this system about the ideal state for any fertile initial state.Finally,its time optimalcontrol on the ideal state is discussed.更多还原
