Check answers to question $3,$ and answer $4$ & $5$:

We have a process shown in the right figure. $($M$1-$M$4$ are names for four

machines. The numbers are activity times in minutes$).$ Consider a schedule:

schedule a job on M$1$ every $8$ minutes, starting at time $0$; schedule a job on M$2$

every $4$ minutes starting at time $0.$ Jobs finished on M$1$ go to M$4$; jobs finished

on M$2$ go to M$3.$

Question $3(1$ point$)$

Find the WIP on each machine and complete the table.

Keep three decimals if required.

$M1=$

A WIP $($units$).$

$M2=$

A WIP $($units$).$

$M3=$

A WIP $($units$).$

M$4$

A WIP $($units$).$

Total $=$

A WIP $($units$).$Question $4(1$ point$)$

The flow time $($average throughput time$)=$

$($Hint: Every $8$ minutes, $3$ job come to the process $(1$ job to M$1,2$ jobs to M$2).$ To

get the average TPT$,$ you need to calculate the throughput time for each of the

three jobs and then do an average.$)$ Keep two decimals.

Question $5(1$ point$)$

The flow rate under the given schedule is $=$

$[$units$/$hour$].$We have a process shown in the right figure. $($M$1-$M$4$ are names for four

machines. The numbers are activity times in minutes$).$ Consider a schedule:

schedule a job on M$1$ every $8$ minutes, starting at time $0$; schedule a job on M$2$

every $4$ minutes starting at time $0.$ Jobs finished on M$1$ go to M$4$; jobs finished

on $M2$ go to $M3.$

Question $3(1$ point$)$

Find the WIP on each machine and complete the table.

Keep three decimals if required.

$M1=$

A WIP $($units$).$

$\backslash$table$[[$M$2=,$A$,$WIP $($units$).],[$M$3=,$A$,$WIP $($units$).]]$

M$4,$ A$/$ WIP $($units$).$

Total $=$

A WIP $($units$).$

Question $4(1$ point$)$

The flow time $($average throughput time$)=,[$minutes$].$

$($Hint: Every $8$ minutes, $3$ job come to the process $(1$ job to M$1,2$ jobs to M$2).$ To

get the average TPT$,$ you need to calculate the throughput time for each of the
