Meaning

Balancing difference (abs)

Time need - Total time of all assigned elements

Calculation: Sum of balancing difference of each resource

Balancing difference of each resource = cycle time * cycle time factor – sum of assigned elements * station factor

Balancing difference (rel.) in %

Balancing difference (abs) / (cycle time * number of operators) * 100%

Rel. Standard deviation (%)

Standard deviation of load of all operators. The value indicates how consistent line balancing among all operators was done. The smaller the value, the more even the balancing is (regardless of load).

Loss of balancing (%)

Balancing difference (abs.) / total time of all assigned elements * 100%

Assembly line efficiency (%)

Total time of all assigned elements / Time need * 100

(Balancing difference (rel.) + Assembly line efficiency = 100%)

100% – Balancing difference (%)

Resources (Station/Operator/Machine)

Number of resources (Station/Operator/Machine) in the assembly line

therefrom w/o load

Number of resources (Station/Operator/Machine) without assigned elements

therefrom overloaded

Number of resources that are overloaded

Total time

Sum of the times of all elements

(depending on the mode in the tab assignment in relation to the cycle or the net working time)

Time requirement

Number of resources (operator/machine) in the assignment * cycle time

(Cross-station resources are only counted once. Station factor and cycle time factor are not included in the calculation)

Resources (station)

Sum of station factor across all stations

Resources (human resource)

Sum of cycle time factor * station factor for all human resources

(Cross-station human resources are only counted once)

Resources (machine)

Sum of cycle time factor * station factor for all machine resources

(Cross-station resources are only counted once)
