Note—On MRP Lot Sizing
提出了一种更简洁的MRP批量确定模型替代方案，修正了Steinberg和Napier原模型中的若干错误，对后续研究有参考价值。
In this Note we present an alternative formulation to the MRP lot sizing model of Steinberg and Napier (SN) (Steinberg, E., H. A. Napier. 1980. Optimal multi-level lot sizing for requirements planning systems. Management Sci. 26 (2) 1258–1271.). The alternative is more parsimonious and the notation less cumbersome. We also point out several errors in the formulation of the SN model which are significant for future research.
