联合补货问题(简称联合补货问题)是供应链管理中的一个基本优化问题,涉及优化从供应商到零售商的货物流动。随着时间的推移,为了回应零售商的需求,供应商通过仓库向零售商发货。目标是安排这些订单,使订购成本和零售商的等待成本之和最小。我们研究了有最后期限的模型的逼近性,其中零售商强加严格的最后期限,而不是等待成本。我们研究了标准线性规划松弛的积分间隙,给出了的一个下界,一个较强的计算机辅助下界,以及的上界和逼近比。以前最好的上界和逼近比是;以前没有发表过下界。对于所有需求周期长度相等的特殊情况,我们给出了的上界和下界,并证明了它的APX-硬度。
The Joint Replenishment Problem () is a fundamental optimization problem in supply-chain management, concerned with optimizing the flow of goods from a supplier to retailers. Over time, in response to demands at the retailers, the supplier ships orders, via a warehouse, to the retailers. The objective is to schedule these orders to minimize the sum of ordering costs and retailers’ waiting costs. We study the approximability of, the version ofwith deadlines, where instead of waiting costs the retailers impose strict deadlines. We study the integrality gap of the standard linear-program (LP) relaxation, giving a lower bound of, a stronger, computer-assisted lower bound of, as well as an upper bound and approximation ratio of. The best previous upper bound and approximation ratio was; no lower bound was previously published. For the special case when all demand periods are of equal length, we give an upper bound of, a lower bound of, and show APX-hardness.
