研究了一类非线性随机种群动力学模型的最优收获控制问题,得出了在外界环境对系统产生影响的条件下,最优控制所满足的必要条件及其最优性组,所得到的结论是确定性种群系统的扩展.
An optimal harvesting control problem for nonlinear stochastic population dy- namic model is studidied.When the external environment impact on the system ,The necessary condition for the optimization and its optimality system was obtained,which extends a result in the deterministic population system.
