摘要
考虑了在订货时间不确定且EOQ不是整数情况下的最优订货量问题。通过平衡不确定性订货时间下库存成本和订货成本的策略,将不确定性订货时间下的最优订货问题转化为求解一般确定性订货时间下的订货问题。并进一步探讨了当EQQ不是整数时,如何通过建立数学规划来得到非平稳最优订货量。在数学规划模型的基础上,提出了一种新的启发式算法,同时给出了和一般求解方法GA算法的数值比较结果,验证了该启发式算法的有效性。
A nonstationary EOQ model with lead time uncertainty was discussed in this paper. Considering the complexity of the order policy with lead time uncertainty, a simple quadratic programming was derived, and then the order policy with lead time uncertainty was easily converted into a general model -with certain lead time. Furthermore, it should be noted that the order quantity is an integer number in practice; however, it is possible that the traditional economic order quantity （EOQ） is not an integer, which would make the stationary EOQ policy not perfectly work for the order system. A heuristic approach was then proposed to solve the corresponding mathematical programming, and some numerical example was adopted to illustrate the proposed approach.
