Process Data

The following summarizes the data collected during the time study:

Assembly Operator 1
Cycle time ~ Trai(35,40,65)seconds * Difficulty Multiplier

Assembly Operator 2
Cycle time ~ TRIA(35,40,65)seconds * Difficulty Multiplier

Clamp Operator
Cycle time ~ TRIA(20 + LOGN(9.66,14.1))seconds * Difficulty Multiplier

Mud/Putty Operator
Cycle time ~ TRIA(15,20,30)seconds * Difficulty Multiplier

Difficulty Multiplier*
1 panel door = 1.0
2 panel door = 1.2
4 panel door = 1.4
6 panel door = 1.6

* A Difficulty Multiplier is necessary since a single panel door is easier/quicker to assembly than a six panel door. To account for this, a Difficulty Multiplier is applied to the cycle time distributions .

Setup time ~ TRIA(20,30,65)minutes
