Recently, scheduling with learning effects has received growing attention. A well-known learning model is called 'sum-of processing-times-based learning' where the actual processing time of a job is a non-increasing function of the jobs already processed. However, the actual processing time of a...

This paper investigates some single-machine scheduling problems with a general learning effect and the group technology assumption. A setup time is incurred whenever the single machine transfers job processing from a family to another family. By the general learning effect, we mean that the...
