摘要
讨论了具有学习效应的2台机器流水作业排序问题,目标函数为极小化总完工时间。首先证明了2个相关引理,基于2个引理和对问题的分析,证明了用SPT算法解决问题的界为一个与工件的最小加工时间和最大加工时间相关的且小于2的一个值。
The paper is discussing flow-shop scheduling of two machines with a learning effect. The objective is to minimize the total completion time. We first prove two related lemmas, then according to the two lemmas and the analysis of the problem, we prove the worst-case bound of SPT algorithm is related to the minimum and maximum processing time of all operations with learning effect, and the number is less than 2.
