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).
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。
In this paper,a variant single machine scheduling problem with both batching and rejection is addressed.
首次考虑了工件可拒绝的单机分批排序问题,目标函数是极小化最大完工时间加上被拒绝工件的拒绝费用之和。
N jobs arrive at same time and need to be processed in batches by the same machine.
文中考虑下述单机分批问题：对时刻零同时到达的ｎ个工件需分成若干批在同台机器上加工，同批工件加工时相邻，任一工件的完工时间为所在批中全部工件完工时的时间，机器每加工一批工件需一相同的调整时间。
In batch culture for Kefiran production with Lactobacillus kefiranofaciens,the maximal values of average specific growth rate and average specific production rate of Kefiran were obtained at a higher temperature(33℃)in the first culture stage,afterwards,their maximums were obtained at a lower temperature(28℃).
分析了温度对开菲尔基质乳杆菌Lactobacillus kefiranofaciens分批发酵生产胞外多糖Kefiran过程的影响,发现在发酵前期细胞平均比生长速率和Kefiran平均比合成速率达到最大值时的温度较高(33℃),在发酵后期二者达到最大值所需的温度较低(28℃),因此提出两阶段温度控制策略以提高Kefiran分批发酵的产量和发酵强度。
