We present an approximation method for the hybrid flow shop scheduling problem based on relaxation and machine learning … exact solutions, which is generally not feasible for NP-hard problems such as hybrid flow shop scheduling. In terms of …

Classical scheduling models build up many practical problems but there arequestions that occur during practice which …. On the other hand, many classical scheduling models allow an arbitrarynumber of task preemptions. In practical …
