Concepts, Theory, and Techniques THE LOT‐SIZE REORDER‐POINT MODEL WITH UPSTREAM‐DOWNSTREAM UNCERTAINTY*
研究了经典批量订货问题中，实际收货数量与订货数量不一致的随机情况，针对缺货情形给出了精确和近似解，假设收货量的标准差与订货量呈线性关系。
ABSTRACT One assumption in the classical lot‐size problem is certainty in the amount requisitioned. In many practical situations, however, the amount received may be a random variable. In this paper, we discuss a lot‐size inventory problem in which the quantity received does not necessarily match the quantity requisitioned. We develop explicit and approximate solutions for the back‐orders case by assuming that the standard deviation of the amount received is linearly related to the quantity requisitioned.
