Abstract: In this paper, we study a single machine scheduling problem in which sub-jobs have due dates. Given a set of jobs, each job is divided into several sub-jobs and each sub-job has a due date. A job is completed on time only if all its sub-jobs are completed before their due dates. We prove that even if each job has two sub-jobs, this problem is NP-hard and there is no FPTAS for this special case. Furthermore, we propose two heuristics for this model and a heuristic to get an upper bound and carry out numerical experiments to compare their performances.

Key words: scheduling, sub-job's due date, heuristic algorithm
