Abstract:
We present a full and correct proof of the fact that the problem of constructing an optimal schedule for the open shop problem with at most m−3 preemptions for an m‑processor system is NP-hard. We also show that the proof of this result given by E. Shchepin and N. Vakhania in Ann. Oper. Res. 159, 183–213 (2008) is incorrect.
