We present a branch-and-bound algorithm which is the first exact procedure specifically designed with regard to this complex flow shop scheduling variant. Also, we propose a new mathematical programming model as well as new lower bounds. Furthermore, we describe an effective genetic algorithm that includes, as a mutation operator, a local search procedure. We report the results of a computational study that provides evidence that medium-sized instances, with up to 176 operations, can be optimally solved. Also, we found that the new proposed lower bounds outperform lower bounds from the literature. Finally, we show, that the genetic algorithm delivers good solutions while requiring short CPU times.enginfo:eu-repo/semantics/restrictedAccessArticle23224226100029379070000810.1007/s10696-011-9079-2Robotic cellFlow shop with transportation times and blockingBranch-and-boundLower boundsGenetic algorithms2-s2.0-79960565314
