SALBP-2 reduces to the identical parallel machine scheduling problem with makespan minimization (P-m parallel to C-max) when precedence relations are ignored providing a lower bound. In a certain layout setting tasks revisiting the same station over consecutive tours might be preferable when the sole objective is to minimize the makespan of producing the order quantity. In this study the tradeoff between the makespans obtained from SALBP-2 and (P-m parallel to C-max) as a function of order quantity is analyzed. A piecewise linear concave makespan function is observed. We developed an alternative model formulation and an iterative solution scheme for makespan minimization for all possible order quantities. The results of our computational experiment indicate that SALBP-2 outperforms for small order quantities whereas (P-m parallel to C-max) yields the best results for larger order quantities. However there is a certain range of order quantity for which the proposed model dominates the other two. Our results are validated in benchmark instances.Englishinfo:eu-repo/semantics/closedAccessAssembly line balancing, Ma kespan minimization, Mathematical model, Cyclic layout settingLOOP LAYOUT, DESIGNAssembly Line BalancingMathematical ModelMakespan MinimizationCyclic Layout SettingMa Kespan MinimizationArticle
