随机离散人口系统建模及稳定性分析
Model Building and Stability Analyzing of Stochastic Discrete Population Systems
-
摘要: 建立了随机人口系统生育、死亡、迁移过程的差分方程模型,对随机离散人口系统按龄均 值和二阶中心矩的Lyapunov稳定性进行了研究,给出了根据我国1987年1％人口抽查资料 进行仿真的结果.Abstract: This paper uses difference equations to model the stochastic population birth-death and migration processes, analyzes the Lyapunov stability of the age-dependent first and second moment of the stochastic discrete population systems, gives the simulation results by using the data of 1987's 1% population census of PRC.
