单台机器带一个维修时间段的排序问题,目标是最小化所有工件的运输时间和.在这篇文章里,重新研究了该问题,并给出了一个时间复杂性为O(n3)的近似算法,将性能比从3/2改进到5/4.

The single-machine scheduling problem with a period of maintenance to minimize total delivery time has been studied. In this paper, we revisit the problem and propose an algorithm with time complexity of O(n3) to improve the worst-case ratio from 3/2 to 5/4.
