CASE $2$

A company is setting up an assembly line to produce cellular telephones. They inte $0$

use line balancing with the longest$-$task$-$time heuristic. They know the demand per hour is

$40$ phones and the productive time per hour is $54$ minutes. Displayed below is the data they

have collected regarding task precedence and times $($in minutes$)$:

$($a$)$ Compute the cycle time.

$($b$)$ Compute the theoretical minimum number of workstations.

$($c$)$ Draw a precedence diagram for the production line to show precedence

relationships.

$(2$ Marks$)$

$($d$)$ Prepare line balancing with the incremental utilization heuristic solution.

$($e$)$ Compute the utilization of the production line.
