The complexity of cyclic scheduling for identical jobs

We consider the Cyclic Job Shop Problem for identical jobs with the criterion for cycle time minimization when the number of simultaneously processed tasks during the cycle time is limited by a constant H. We prove that this problem is NP-hard in the case H ≥ 4. For the case H = 2, we propose an exact polynomial algorithm.
Ill. 7, bibliogr. 16.

Keywords: identical tasks, cyclic scheduling.
