Abstract

We consider in this paper the single-machine preemptive scheduling problem with job release dates, delivery times and preemption penalties, where each time a job is started, whether initially or after preemption, a job-dependent setup must take place. First, we prove that the problem is strongly NP-hard. Then, we present a dynamic programming algorithm and a polynomial time approximation scheme.
