Maximizing comfort in Assembly Lines with temporal, spatial and ergonomic attributes

open access: yesInternational Journal of Computational Intelligence Systems, 2016
We aim at maximizing the comfort of operators in mixed-model assembly lines. To achieve this goal, we evaluate two assembly line balancing models: the first that minimizes the maximum ergonomic risk and the second one that minimizes the average absolute ...
