A production line is to be designed for a job with three tasks.The task times are 0.6 minutes,1.8 minutes,and 1.2 minutes.If the necessary cycle time is 1.2 minutes per unit,what is the theoretical minimum number of workstations?
A)2.0
B)3.0
C)3.6
D)4.0
E)4.2

Question

The theoretical minimum number of workstations is calculated using the formula N = ∑Ti / C where N is the number of workstations, Ti is the task time for the i-th task, and C is the cycle time. Plugging in the numbers, we get N = (0.6 + 1.8 + 1.2) / 1.2 = 3. Therefore, the best choice is B, with 3 workstations being the theoretical minimum needed to meet the necessary cycle time.
