分析了多个供应商对同一库存产品进行补货的问题。补充订单分为几个部分，每个供应商一个部分，这些部分的订单同时向相应的供应商发出。近似表达式推导出的平均值和方差的有效提前期，这是最小的每个供应商的个人提前期。这些结果给出了有效的提前期需求的平均值和方差小于单个供应商。研究结果可用于降低库存策略的运行成本。
This paper analyses the use of multiple suppliers to replenish one stock item. The replenishment order is split into several portions, one for each supplier, and orders for these portions are placed simultaneously with the respective suppliers. Approximate expressions are derived for the mean and variance of the effective lead time, which is the minimum of the individual lead times of each supplier. These results give effective lead-time-demand mean and variance that are smaller than those of the individual suppliers. The results can be used to lower the operating cost of the stocking policy.
