摘要 研究一类具有年龄结构的捕食-食饵种群动力系统的最优收获策略.由M azur′s定理,证明了最优控制问题解的存在性以及借助于法锥概念得到了最优控制问题解存在的必要条件,推广了已有的结果. We investigate optimal policy for a predator-prey system with age-dependent. The existence of optimal control strategy is discussed, optimality condition is derived by means of normal cone. Our results extend some known criteria.
