摘要
讨论了一类具有空间扩散和年龄结构的随机种群系统的最优控制问题.在考虑外界存在扰动的情况下,假定扰动系数为线性的,从而利用哈密尔顿函数导出其伴随方程,并根据伊藤公式和随机极大值原理推出了控制为最优的充分必要条件.
In this paper, an optimal stochastic control problem in population system with spatial diffusion and age-structure is discussed. Supposed that these disturbance coefficients to be linear when the external disturbance is exist, the adjoint equation is deduced by using Hamilton function and the necessary and sufficient conditions of optimality is obtained based on stochastic maximum principle and Ito's formula.
