You have just determined the actual number of workstations that will be used on an assembly line to be 8 using the assembly-line balancing procedure. The cycle time of the line is 600 seconds and the sum of all that tasks required on the line is 60 minutes. Which of the following is the correct value for the resulting line's efficiency? a) 0.00125
b) 0.5
c) 0.650
d) 0.750
e) 0.835

d) 0.750

Explanation:

The computation of the correct value for the resulting line's efficiency is shown below:

Efficiency = All task times sum ÷ (Actual number of workstations × cycle time)

where,

All task times sum is 60 minutes

The Actual number of workstations is 8

And, the cycle time is

Since 600 seconds = 10 minutes

And 1 minute = 60 seconds

So, the cycle time would be

= 600 ÷ 60

= 10 minutes

Now placing these values to the above formula

So, the resulting line's efficiency is

= 60 ÷ (8 × 10)

= 60 ÷ 80

= 0.750
