The production and inventory systems taking account of time value
本文运用现值法讨论考虑时间价值的最优库存策略，改进了Chung（1996）的算法，能快速准确计算最优订货时间间隔。
This paper discusses the optimal inventory policies taking account of time value by applying the concept of the present value method, and answers all open questions mentioned in Chung (Production Planning & Control, 1996, 7, 264- 267). A simple algorithm to compute the optimal ordering time interval is developed to improve Chung's paper. Numerical examples reveal that the solution algorithm described in this paper is accurate and rapid.
