摘要
研究了一类污染环境中具有尺度结构的周期种群系统的最优生育率控制问题.得到了生育率控制为最优的必要条件和由积分—偏微分方程和变分不等式所构成的最优性组.
The optimal fertility control problem is studied for a type of periodic population system with scale structure in polluted environment. The essential conditions for optimal fertility control and the optimality system composed of integral-partial differential equations and variational inequalities are obtained.
