A company is designing a product layout for a new product. It plans to use this production line eight hours a day in order to meet a schedule of 400 units per day. The tasks necessary to produce this product are detailed in the table below.
$\begin{array}{|c|c|c|}
\hline\text { Task } & \text { Predecessor } & \begin{array}{c}
\text { Time } \
\text { (seconds) }
\end{array} \
\hline \mathrm{A} & - & 50 \\hline \mathrm{B} & \mathrm{A} & 36 \
\hline \mathrm{C} & - & 26 \
\hline \mathrm{D} & - & 22 \
\hline \mathrm{E} & \mathrm{B}, \mathrm{D} & 70 \
\hline \mathrm{F} & \mathrm{C}, \mathrm{E} & 30 \
\hline
\end{array}$
a. Draw the network described in the table.
b. Without regard to a production schedule, what is the minimum possible cycle time (in seconds) for this situation; what is the maximum?
c. What is the required cycle time (in seconds) in order to meet the schedule?
d. What is the theoretical minimum number of workstations needed to meet the schedule?
e. Balance this line using longest processing time.
f. What is the efficiency of the balance obtained in part e?
