BLAZEWICZ, Jacek; ECKER, Klaus; KIS, Tamás  and  TANAS, Michal. A note on the complexity of scheduling coupled tasks on a single processor. J. Braz. Comp. Soc. [online]. 2001, vol.7, n.3, pp.23-26. ISSN 0104-6500.

This paper considers a problem of coupled task scheduling on one processor, where all processing times are equal to 1, the gap has exact length h, precedence constraints are strict and the criterion is to minimise the schedule length. This problem is introduced e.g. in systems controlling radar operations. We show that the general problem is NP-hard.

Keywords : Scheduling; coupled tasks; NP-hardness.
