Question

A ten-station transfer machine has an ideal cycle time of 30 sec. The frequency of line stops is 0.075 stops per cycle. When a line stop occurs, the average downtime is 4.0 min. Determine the line efficiency. A. 62.5% B. 37.5%

Answer 1

Answer:

62.5%

Explanation:

We are given that

A ten-station transfer machine has ideal cycle time=30 sec=$\frac{30}{60}=0.5 min$

Frequency of line=0.075 stops per cycle

Average time=4 min

We have to determine the line efficiency

$T_p=0.5+0.075(4)=0.5+0.3=0.8$

Line efficiency=$\frac{0.5}{0.8}\times 100=$62.5%

Hence, the line efficiency=62.5%
