Seru Seisan‐ an innovation of the production management Mode in Japan

Reconfiguration of assembly systems: From conveyor assembly line to serus

“…Constraint (13) indicates that the number of tasks processed in each seru is above the lower bound of the number of workstations in one seru. Constraint (14) means that one worker can not be assigned to more than one seru simultaneously. Constraint (15) ensures that a product batch is only assigned to one seru.…”

“…Previous literature [11,12,14,27] shows that three types of seru are broadly adopted by manufacturing factories. The first type is divisional seru, in which processes are divided separately for several workers to cooperate with each other among workstations in the reconfigured assembly lines, U-shaped in principle.…”

“…Firstly, significant improvement in manufacturing flexibility [14,28,29]. Serus are established by using movable workstations, light equipment, and multi-skilled workers.…”

Definition and Verification of Workers' Aptitude Toward Assembly Tasks in Production Cells

“…Some of the reported benefits of cell production are reduced setup times, reduced in-process inventories, improved product quality, shorter lead times, reduced tool requirements, improved productivity, and better overall control of operations. Furthermore, implementation of cell production has been shown to achieve significant improvements in space utilization and employee morale [1] .…”
