  Minimizing makespan on parallel machines with release time and machine

  Pinedo demonstrated that the least flexible job LFJ rule was optimal for minimizing makespan in a parallel machine environment with equal processing times when there are machine eligibility restrictions the machine eligibility sets are nested and no release time constraint exists The results presented in this paper demonstrate that for
