Modeling and numerical analysis of line-cell conversion problems

How to carry out assembly line–cell conversion? A discussion based on factor analysis of system performance improvements

“…Despite of these differences, a seru is very similar to an assembly cell. To be consistent with previous research (Kaku et al 2009), we use ''assembly cell'' in this paper to represent the seru and call the conversion from assembly lines to serus ''line-cell conversion''.…”

“…The improved performance of assembly system should also be evaluated. These decision problems were defined as line-cell conversion problems by the previous studies (Kaku et al 2008a(Kaku et al , 2008b(Kaku et al , 2009.…”

Reconfiguration of assembly systems: From conveyor assembly line to serus

“…The computation results of the proposed model is compared to that by the Kaku's model [36] under the same worker assignment plan, seru loading and dispatching rules. This comparison is based on the seru-line combined system with 3 serus under plan 6-5-5.…”

“…In the other work, Kaku et al [36] proposed a two-stage approach to design seru systems, incorporating seru formation stage and product dispatching stage. And then they developed a mathematical model in the context of complex and intense surging uncertainties in production environments.…”

“…Among all the negative factors, the optimal working range and the difference in individual abilities have been extensively investigated in the literature. First, the optimal working range of multi-skilled workers is with a certain limit [36]. Although workers after crossed-training are qualified with multiple skills, if the number of tasks the worker possesses exceeds that in his optimal condition, the processing time for each task tends to become longer compared to his optimal state.…”
