摘要:在本文,我们证明链式先后关系下的单机分批排序问题是强NP困难的,解决了Albers和Brucker(1993)提出的待解决问题.关于此问题,Albers和Brucker(1993)也曾试图给出NP困难性证明,我们阐明了其证明中存在的缺陷.
In this paper, we show that one-machine scheduling problem with batching under chainlike precedence constraints is strongly NP-hard, which answers an open question proposedin Albers and Brucker (1993). In addition, we point out the error of Albers and Brucker(1993)'s proof on the ordinary NP-hardness of the poblem.
