Balancing Efficiency

An efficient line balancing will minimize the amount of idle time.

 The balance efficiency can be calculated as

  • EffB = output of task time / inputs by workstation time =

 ∑t/ CT * N

Where,

∑t = sum of the actual worker times or task times to complete one unit.

Ct = cycle time

N= No of workers or work stations

  • EffB = theoretical minimum number of workers / actual number of workers

The grouping of tasks is done with the aid of a precedence diagram. The precedence diagram  is  divided  into work  zones or stations  and the  appropriate activities  are grouped under  each  workstation,  until  the cycle  time is  as fully  utilized as possible.
