Recently, Huang and Hsu (J Oper Res Soc Jpn 50:1–13, 2007) investigated the retailer’s optimal replenishment policy with non-instantaneous receipt under trade credit and cash discount. Basically, their inventory model is correct and interesting. However, they ignored explorations of interrelations of functional behaviors of the annual total cost to locate the optimal solutions so much so that the accuracy and reliability of the process of the proof of their solution procedure are questionable. The main purpose of this paper is to provide accurate and reliable mathematical analytic solution procedures to improve the findings in the aforementioned work of Huang and Hsu (J Oper Res Soc Jpn 50:1–13, 2007). Some related recent works on the subject-matter of this investigation are also cited with a view to providing incentive and motivation for making further advances along the lines of the supply chain management and associated inventory problems which we have discussed in this article.

供应商信用下非即时收货的EOQ模型准确可靠的数学解析解法

最近，Huang 和 Hsu (J Oper Res Soc Jpn 50:1–13, 2007) 研究了零售商在贸易信贷和现金折扣下非即时收到的最佳补货策略。基本上，他们的库存模型是正确且有趣的。然而，他们忽略了对年度总成本的函数行为相互关系的探索，以致于对最优解的定位导致其求解过程证明过程的准确性和可靠性值得怀疑。本文的主要目的是提供准确可靠的数学分析求解程序，以改进 Huang 和 Hsu 上述工作中的发现（J Oper Res Soc Jpn 50:1-13, 2007）。
