“…The balancing problem in MMAL line is more difficult since it must be determined which worker performs which tasks, besides the workstation assignment (Roshani & Giglio, 2017;Roshani et al, 2013). Some studies in the ALBP field of research addressed walking workers or travelling workers option, considering, thus, the possibility that workers travel along the line (Sikora et al, 2017;Nakade & Nishiwaki, 2008;Cevikcan, 2016;Al-Zuheri et al, 2013;Al-Zuheri et al, 2016). But, the ALBP literature mainly considers optimization algorithms used in the design phase of an assembly line with a limited number of different products, aimed at finding the allocation of tasks to workstations, and which worker has to perform them (in the case of walking workers), maximizing an objective function i.e.…”
