Question

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 10 minutes 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

Answer 1

Answer:

D

Explanation:

We will use the assembly line balancing equation to solve this problem.

The equation is:

$Efficiency=\frac{Sum \ of \ task \ times}{Total \ time}$

The sum of task times is given as "60 mins"

Now, the Total time would be the number of workstations multiplied by the cycle time of each.

Number of Workstations = 8

Cycle Time = 10 minutes

Hence, total time is:

8 * 10 = 80

Now, efficiency:

$Efficiency=\frac{Sum \ of \ task \ times}{Total \ time}\\Efficiency=\frac{60}{80}=0.75$

Correct answer is D
