re-balancing often leads to a substantial
mitigation in ergonomic risks. Thus, for 50% of instances
a balance with acceptable level of risks for all the stations was
found without increasing the number of stations. In the cases,
where an increase in number of stations was required, such a solution
was found after just about 4% increase in the line capacity.
Further, our computational experiments indicate that, in general,
with each new working station the improvement of ergonomic
risks diminishes
