Hybrid Flow shop with uniform machines, different release time and transportation time between stages

In this paper a hybrid flow shop problem with different release times is studied. To make a problem more realistic, it is assumed that process time of each job depends on the speed of machines. Due to a distance between locations of different stages, transportation time between successive stages is considered too. In this research two models that differ in terms of their relative objectives are introduced. First objective concerns with minimizing makespan while the second refers to minimizing total lateness costs
