Answer 1

Answer

The efficiency of the assembly line can be calculated as:

Efficiency = (process time/ Lead time)

So, let's calculate the Lead time:

Given values: cycle time = 10 minutes. And number of workstations NT=3.

Thus, Lead time = cycle time * number of workstations.

Lead time = 10 * 3

Lead time = 30.

Now, sum of process time = 28.6 minutes.

Therefore,

Efficiency = 28.6/30

Efficiency = 0.9533

Efficiency = 95.33 %.
