本文考虑了需求预测改善时初始批量数量的选择。我们假设每一时期需求的标准差呈指数递减，接近于一个长期值。考虑离散时间随机单级库存模型。除了订购成本外，还有传统的保留成本和缺货成本。订购期必须提前确定，我们希望确定一个合适的时间表。
This paper considers the choice of initial batch quantities when demand forecasts are improving. We assume that the standard deviation of the demand per period is decreasing exponentially and approaching a long-run value. A discrete time stochastic single-level inventory model is considered. There are traditional holding and backorder costs as well as an ordering cost. The ordering periods must be determined in advance, and we wish to determine a suitable schedule.
