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-
We consider a polynomial-time algorithm for the following scheduling problem: Given two machines, where each machine can process at most one job at a time; a set of jobs, where each job can start on or after its release date and consists of a chain of unit-time operations such that the machines have
