...Aslihan Karas Celik; Feristah Ozcelik Purpose This study addresses the assembly line balancing problem with hierarchical worker assignment (ALBHW) in U-shaped assembly lines. Despite their practical relevance, U-shaped ALBHW problems have only been explored through exact solution approaches, which...

... that has good performance under all possible scenarios. The proposed model allows decision makers to minimize a posteriori regret of the selected choice and hedge against the high cost caused by variability. Design/methodology/approach A generalized resource-constrained assembly line balancing...

...Masood Fathi; Amir Nourmohammadi; Amos H.C. Ng; Anna Syberfeldt; Hamidreza Eskandari Purpose This study aims to propose an efficient optimization algorithm to solve the assembly line balancing problem (ALBP). The ALBP arises in high-volume, lean production systems when decision-makers aim...
