本文研究了交货时间的均值和方差随供应商数量的变化规律。利用已知的“第一”和“间隔”交货时间的均值和方差分析结果,我们给出了当交货时间均匀分布或指数分布时寻找最佳供应商数量的简单决策规则。
This paper investigates how the mean and variance of lead time change with the number of suppliers. Using known analytical results for the means and variances of the ‘first’ and ‘spacing’ lead times, we give simple decision rules to find the optimal numbers of suppliers when lead times are uniformly or exponentially distributed.
