摘　　要：以装配型企业为背景,基于泊松分布需求,针对"半成品库-成品库"二级库存控制系统模型,证明了备运期内半成品库的缺货次数属于泊松过程,得出以订货费、存储费及缺货损失费组成的库存成本为目标的优化函数,并给出迭代求解算法,通过算例验证了模型的有效性。Aimming at two-echelon control for semi-finished and finished product stock,it proves that the stock out number of the semi-finished product stock belongs to Poisson process during the lead time,based on assembly enterprises as a background and Poisson distribution demand.This annlysis gives the cost function of the 'semi-finished product stock and finished product stock' two-echelon inventory model,where the cost function consists of order fee,storage fee and shortage fee.It presents the optimization function algorithm and an example for verifing the validity of the model.
