摘要:本文研究以加工总长为目标函数的三台机器流水作业问题的特殊情形的计算复杂性,证明了下列情形为NP困难的:所有工件在第二台机器上有相同的加工时间;所有工件在第一和第三台机器上有相同的加工时间;每个工件至少有一个零工序;每个工件有一个丢失的工序。
In this paper, we investigate the computational complexity of some special cases of the three-machine flow-shop problem to minimize the makespan. NP-hardness is estab- lished for each of the following cases: all jobs require the same processing time on the second machine; all jobs require the same processing time on the first machine and the last machine; each job has at least one zero operation; each job contains a missing operation.
