摘要
传统的确定性经济批量模型通常都假定需求率是常数,且每周期的相关费用是固定不变的。弱化这些假定,并在每周期的需求依赖于抛物型需求的假设下,提出了带有两货栈的变质性物品在有限计划期内的经济批量模型。研究了该模型具有惟一的整体最优解,并给出应用实例。
Traditional deterministic economic Lot-Size models assume that the demand rate is a constant, that the order cost is inflexible during every order cycle. In this paper, we relax these assumptions and assume that the demand for each cycle depends on parabollic demand. We develop an economic Lot-Size model for deteriorating items with two warehouses during the finite planning period. The existence of the unique optimal replenishment schedule is shown and numerical example is also qiven in the paper.
