摘　　要：采用排队分析技术,构建基于利润最大化的库存控制模型来考察零售商面向两类客户需求的环境下,双渠道采购库存控制策略.首先,建立了库存水平状态稳态概率分布的平衡方程,并推导出其稳态概率分布以及作为构建系统利润函数的稳态性能指标.然后,建立系统利润最优化模型,并设计改进的遗传算法.最后,通过数值实验考察系统库存控制策略以及参数的敏感性.This paper focus on an inventory system with dual-channel procurement and two demand types. The optimal inventory control policies are discussed according to the maximal profit model by queueing theory. Firstly, the balance equations of steady-state probability distributions are established and furthermore the steady-state performance measures, which are used for controlling profit function, are derived. Secondly, the system profit function is characterized and the optimization model is built. According to the nature of the optimization model, an improved genetic algorithm is proposed. Finally, the inventory＇control strategies and the sensitivities of the system parameters are investigated through numerical experiments.
