You have just determined the actual number of workstations that will be used on an assembly line to be 5 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 25 minutes. Which of the following is the correct value for the resulting line's efficiency?

Cycle time = production time per day / output per day.

Efficiency = Sum of all task time / (Actual number of work station x Cycle time)

Thus:

[25 / ( 5 x 10 ) ] =  0.5

Step-by-step explanation:

To understand how we arrived at 0.5 line efficiency, we go ahead to briefly discuss what the assembly line balancing procedure is.

The assembly line balancing procedure is refereed to as a process of delegating designated variables or integers to workers for each operations of an assembly line for the purpose of helping the workers meet required production rate with minimum or zero ideal time.

Recalling the formula used in calculating line efficiency, we have:

Efficiency = Sum of all task time / (Actual number of work station x Cycle time)

and the formula used in calculating cycle time, we have:

Cycle time = production time per day / output per day.

However, at this time, we are utilizing the formula for efficiency where:

25 = Sum of all task time

5 = Actual number of work Station

10 = Cycle time

Now, if we insert the values or parameter into the formula of efficiency, we have:

[25 / ( 5 x 10 ) ]= 0.5

Therefore, the line efficiency is o.5
