| 摘 要： | 首先建立需求形式为一般随机变量情形下零售商的两次订购决策模型,并从理论上证明了在两个阶段需求相互独立情形下,零售商期望利润函数的下凹性及最优订购策略的存在唯一性,从而弥补了已有模型在寻求最优订购策略时采用数值方法所存在的缺憾;然后,建立两阶段需求相关情形下带有两次订购的Newsboy模型,给出了模型的分析解.数值实例验证了模型的求解过程,并得到了相关管理启示.

| Abstract: | The two-ordering decision models are established by considering that the demand distributions have general distribution forms.The concaveness of the retailer's expected profit and existence and the uniqueness of optimal ordering policies are proved under the assumption that the first-period and the second-period demands are independent.The two-ordering Newsboy model is developed by considering the correlation between the first-period and the second-period demands.An analytical solution is provided to find t... |
