Question

An assembly line consists of 21 tasks grouped into 5 workstations. The sum of the 21 task times is 85 minutes. The largest assigned cycle time is 20 minutes. What is the efficiency of this line

Answer 1

Answer:

The efficiency of this line is 0.85 = 85%.

Step-by-step explanation:

Efficiency:

The efficiency is given by the following formula:

$E = \frac{T_t}{tn}$

In which $T_t$ is the total task time, $t$ is the largest assigned cycle time and n is the number of workstations.

5 workstations

This means that $n = 5$

The sum of the 21 task times is 85 minutes.

This means that $T_t = 85$

The largest assigned cycle time is 20 minutes.

This means that $n = 20$

What is the efficiency of this line?

$E = \frac{T_t}{tn} = \frac{85}{20*5} = \frac{85}{100} = 0.85$

The efficiency of this line is 0.85 = 85%.
