Dynamic Version of the Economic Lot Size Model
给出一种前向算法，求解单物品需求、库存持有成本和设置成本在N期内变化的动态经济批量模型，得到最小总成本的库存管理方案，并证明不连续规划期可能消除对完整N期数据的需求。
A forward algorithm for a solution to the following dynamic version of the economic lot size model is given: allowing the possibility of demands for a single item, inventory holding charges, and setup costs to vary over N periods, we desire a minimum total cost inventory management scheme which satisfies known demand in every period. Disjoint planning horizons are shown to be possible which eliminate the necessity of having data for the full N periods.
