Abstract
In this paper, we present \(\mathcal{N}\mathcal{P}\)-hardness proofs and exhibit linear-time algorithms for proportionate two-machine open shop and job shop problems with respect to the maximum lateness, the makespan with release dates, the total weighted completion times and the number of just-in-time jobs.
