Draw a precedence diagram $($finish the one started$)$

If the desired output rate is $30$ units per hour, what are the cycle time and

theoretical minimum?

$c=\frac{1}{r}=$

$TM=\frac{{\displaystyle \underset{?}{\overset{?}{}}}t}{c}=$

Suppose that we are fortunate enough to find a solution with just four stations.

What is the idle time per unit, efficiency, and the balance delay for this

solution?

Idle time $=nc-{\displaystyle \underset{?}{\overset{?}{}}}t=$

Efficiency$(\%)=\frac{{\displaystyle \underset{?}{\overset{?}{}}}t}{nc}(100)=$

Balance delay $(\%)=100-$ Efficiency $=$
