An assembly line with 28 activities is to be balanced. The total amount of time required for all 28 activities is 39 minutes. The line will operate for 300 minutes per day. What must the cycle time be to achieve an output rate of 250 units/day?
A) 1.39 minutes
B) 11.2 minutes
C) 1.2 minutes
D) 0.89 minutes

Question

First, we need to determine the theoretical maximum output rate of the assembly line:
Maximum output rate = (Available operating time per day) / (Cycle time)
Maximum output rate = 300 minutes / Cycle time

To achieve an output rate of 250 units/day, we can set up the following equation:
250 units/day = (Available operating time per day) / (Cycle time)

Solving for the cycle time:
Cycle time = (Available operating time per day) / (Output rate)
Cycle time = 300 minutes / 250 units/day
Cycle time = 1.2 minutes

Therefore, the cycle time must be 1.2 minutes to achieve an output rate of 250 units/day. Option C is the correct answer.
