#$5)$ Consider a dental office that has six employees, a receptionist, a dentist, and four#$6)$ Suppose a close friend has decided to open up a food truck to serve lunch in downtown

Detroit. She has hired a consultant to estimate the lunchtime $(11$:$00-2$:$00)$ demand for the

truck and they have given her the following forecast: M$-$F$,350$ customers over the three

hour block; and Saturday and Sunday, $450$ customers over the three hour lunch block.

The truck has now been open for three weeks with lots of advertising, deals, and extra

staff and the following customer counts have been observed over the three hours each

day.

She estimates that each staff member gives a capacity of about $25$ customers per hour at

the truck. $(20$ pts total$)$

A$)$ Prepare a forecast of your own based on the actual data, be clear how you developed it

and show the MAD and CFE for your forecast. $(8$ pts$)$

B$)$ Recommend a staffing level for M$-$F and Sa$-$Su$.(4$ pts$)$

C$)$ What is the numerical capacity cushion that you recommended? $(4$ pts$)$

D$)$ Justify specifically why you advise this staffing level and capacity cushion? $(4$ pts$)$

hygienists. The transformation process for standard teeth cleaning at the office is as

follows in order, due to procedures the dentist only has $5$ hours available per day while

the other employees have $8$ hours per day. $(20$ points, $4$ for each answer$)$

A$)$ What is the capacity of this process?

B$)$ What is the bottleneck of this process?

C$)$ What is the minimal throughput time for one customer $($flow time$)?$

D$)$ What is the flow rate $($throughput rate$)?$

E$)$ What is the average throughput time $($flow time$)$ if the total number of patients both

being helped as well as waiting for their turn to be helped is $6?($Hint: You can use

Little's Law, $F=\frac{\text{I}}{T})$
