This paper considers a three-stage assembly flowshop scheduling problem with sequence-dependent setup < /div>
times at the first stage and blocking times between each stage in such a way that the weighted mean
completion time and makespan are minimized. Obtaining an optimal solution for this type of complex,
large-sized problem in reasonable computational time using traditional approaches or optimization tools is
extremely difficult. Thus, this paper proposes a meta-heuristic method based on simulated annealing (SA) in
order to solve the given problem. Finally, the computational results are shown and compared in order to show
the efficiency of our proposed SA.
