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.

M$1=$

A WIP $($units$).$

M$2=$

A WIP $($units$).$

M$3=$

A WIP $($units$).$

M$4$

A WIP $($units$).$

Total $=$

A WIP $($units$).$Consider the Chipotle example we discussed in the class. But this time, both Under the arrival schedule given in the previous question Week $2$ Exercise $-$

Gantt Chart, calculate the following run$-$time parameters:

Demand Rate:

A unit$($s$)/$hour$.$

Flow Rate:

A$/$ unit$($s$)/$hour$.$

Actual Cycle Time:

A sec$/$unit$.$

WIP for M$1$:

A$/$ unit$($s$).$

WIP for M$2$:

A$/$ unit$($s$).$

WIP for Buffer:

A$)$ unit$($s$).$

WIP for M$3$:

A$/$ unit$($s$).$

Total WIP:

A$/$ unit$($s$).$

Flow Time:

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

Question $3(1$ point$)$

Find the WIP on each machine and complete the table.

Keep three decimals if required.

$M1=$

A WIP $($units$).$

$M2=$

$M3=$

M$4$

M$4$

Total $=$

A WIP $($units$).$

A WIP $($units$).$ 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

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

Question $5(1$ point$)$

The flow rate under the given schedule is $=$

$[$units$/$hour$].$

A$/$

workers M$1$ and M$2$ need a longer time to finish their tasks $($the activity times

change to $90$ seconds and $60$ seconds, respectively$).$

Question $1(1$ point$)$

Calculate the following design parameters for this process:

Cycle time $($CT$)$ for Stage $1$:

A $s\frac{ec}{?}$ unit.

CT for Stage $2$:

A sec $/$ unit.

Bottleneck is in Stage:

A$/$

Process Designed CT:

A sec $/$ unit.

Process Capacity:

A$/$ units $/$ hour.
