Question

A fast-food franchise is considering operating a drive-up window food-service operation. Assume that customer arrivals follow a Poisson probability distribution, with an arrival rate of 24 cars per hour, and that service times follow an exponential probability distribution. Arriving customers place orders at an intercom station at the back of the parking lot and then drive to the service window to pay for and receive their orders. The following three service alternatives are being considered:

System A: A single-server operation in which one employee fills the order and takes the money from the customer. The average service time for this alternative is 2 minutes.

System B: A single-server operation in which one employee fills the order while a second employee takes the money from the customer. The average service time for this alternative is 1.25 minutes.

System C: A two-server operation with two service windows and two employees. The employee stationed at each window fills the order and takes the money for customers arriving at the window. The average service time for this alternative is 2 minutes for each server.

The following cost information is available.

- Customer waiting time is valued at $25 per hour to reflect the fact that waiting time is costly to the fast-food business.
- The cost of each employee is $6.50 per hour.
- To account for equipment and space, an additional cost of $20 per hour is attributable to each server.

What is the lowest-cost design for the fast-food business? If required, round your answers to two decimal places.

Total Cost | |
---|---|

System A | $ ____ |

System B | $ ____ |

System C | $ ____ |

System ______ is the most economical.

Question 2
A fast-food franchise is considering
operating a drive-up window food-service operation. Assume that
customer arrivals follow a Poisson probability distribution, with
an arrival rate of 24 cars per hour, and that service times follow
an exponential probability distribution. Arriving customers place
orders at an intercom station at the back of the parking lot and
then drive to the service window to pay for and receive their
orders. The following three service alternatives are being
considered:

28. You are the manager of a restaurant for a fast-food
franchise. Last month, the mean waiting time at the drive-through
window for branches in your geographical region, as measured from
the time a customer places an order until the time the customer
receives the order, was 3.8 minutes. You select a random sample of
81 orders. The sample mean waiting time is 3.99 minutes, with a
sample standard deviation of 0.9 minute.

A manager of a fast food restaurant wants the drive-thru
employee to ask every fifth customer if he or she is satisfied with
the service. Who makes up the population?
A.
All survey respondents
B.
The proportion of customers who say they are satisfied with
their service

To encourage efficiency at a drive through window, a fast food
restaurant chain specifies, as a guideline, that at least half of
all drive through orders should be taken, prepared, and delivered
in 3 minutes or less. Subsequently, a random sample of 64 drive
through orders was taken and it was found that 24 of them were
taken, prepared and delivered in 3 minutes or less. The remaining
orders from the sample took longer than 3 minutes. The fast food...

Suppose 50 people come to a fast food
take-out
restaurant each hour. There are four employees, one
at
the register, two making the food, and one packaging
the
food. Suppose on average, each order takes 30
seconds
at the register, and it takes one employee an average
of
1.5 minutes to make the food, and it takes 1 minute
on
average to package the food. Assume exponential
arrivals
and service times.
1) How many people typically are waiting in line...

Burrito King (a new fast-food franchise opening up nationwide)
has successfully automated burrito production for its drive-up
fast-food establishments. The Burro-Master 9000 requires a constant
30 seconds to produce a batch of burritos. It has been estimated
that customers will arrive at the drive-up window according to a
Poisson distribution at an average of one every 55 seconds. To help
determine the amount of space needed for the line at the drive-up
window, answer the following questions.
a. What is...
