What is it about?
We study a class of new scheduling models where time slot costs have to be taken into consideration. In such models, processing a job will incur certain cost which is determined by the time slots occupied by the job in a schedule. The objective of the scheduling models is to minimize the total time slot costs plus a traditional scheduling performance measure. We consider the following performance measures: total completion time, maximum lateness/tardiness, total weighted number of tardy jobs, and total tardiness.

Why is it important?
The models apply when operational costs vary over time.
Perspectives
This is a joint work with Prof. Xiangtong Qi, an expert in scheduling and optimization areas. The motivation is from varying electricity prices when processing jobs using high electricity.
