摘要
介绍了一类与年龄相关的模糊随机种群扩散系统,它同时受随机和模糊两种不确定性因素的影响.在有界条件(弱于线性增长条件)和Lipschitz条件下,运用Picard迭代法证明了与年龄相关的模糊随机种群扩散系统解的存在唯一性,并且给出Picard迭代近似解误差的估计式.
In this paper,we introduce a class of stochastic fuzzy age-structured population system with diffusion.Where the phenomena are subjected to two kinds of uncertainties:stochastic and fuzziness,simultaneously.Under a boundedness condition,which is weaker than linear growth condition,and the Lipschitz condition we obtain existence and uniqueness of solution to stochastic fuzzy age-structured population system with diffusion.Solutions,which are fuzzy stochastic processes,and their uniqueness are considered to be in a strong sense.An estimation on the error of approximate solution of the Picard iteration is given.
