中文摘要：

在具有学习效应的环境下，由于机器重复加工相同或相似的工件，因此以后加工的工件的加工时间变小．本文研究新的更一般的学习效应：Dejong学习效应．我们证明单机最大完工时间问题，总完工时间问题和两类多目标问题是多项式时间可解的．

英文摘要：

In a learning effect environment, the machine improves continuously as a result of repeating the same or similar jobs, hence the later a given job is scheduled in the sequence, the shorter its processing time is. In this paper, we consider a new general learning effect, i.e. Dejong＇s learning effect. Using this Dejong＇s learning effect polynomial solutions for the single machine makespan minimization problem, total flow time minimization problem and two classes of single machine multi-criteria problems are obtained.
