本文对具有不可忽略的补货提前期的两地定期审查库存系统进行分析。这些系统中使用紧急转运作为一种追索行动，以减少短缺的发生。提出了一类部分集中政策来控制转运。此类保单的性价比明显低于完全统筹的保单。引入近似模型和启发式算法来计算接近最优的库存策略解决方案。与仿真结果的比较验证了近似模型和算法的良好性能。数值敏感性分析提供了对最佳转运行为本质的额外见解。
This paper deals with the analysis of two-location periodic review inventory systems with non-negligible replenishment lead times. Emergency transshipments are used in these systems as a recourse action to reduce the occurrence of shortages. A class of partial pooling policies is proposed for the control of transshipments. The cost performance of this class of policies is shown to be inferior to that of complete pooling. An approximate model and a heuristic algorithm are introduced to compute near-optimal stocking policy solutions. Comparisons with simulation results verify the satisfactory performance of the approximate model and algorithm. Numerical sensitivity analysis provides additional insight into the nature of optimal transshipment behavior.
