Chapter F, Problem 6P
Summary Introduction
To determine: The number of people who arrive at the checkout of the store and the time it takes to check them out.
Introduction: Simulation is the model that can be used in operations, which would imitate the real world process. Simulation uses random sampling for the generation of realistic variability.

QUESTION 5
Regional Airlines is establishing a new telephone system for handling flight reservations. During the 10:00 AM to 2:00 PM time period,
calls to the reservation agent occur randomly at an average rate of one call every 3.75 minutes. Historical service time data show that a
reservation agent spends an average of 3 minutes with each customer. The waiting line model assumptions of Poisson arrivals and
exponential service times appear reasonable for the telephone reservation system.
At a planning meeting, Regional's management team agreed that an acceptable customer service goal is to answer at least 75% of the
incoming calls immediately. During the planning meeting, Regional's vice president of administration pointed out that the data show that
the average service rate for an agent is faster than the average arrival rate of the telephone calls. The vice president's conclusion was
that personnel costs could be minimized by using one agent and that single agent must be able to…

Question 8
(Atlantic Video) Atlantic Video, a small video rental store in Philadelphia, is open 24 hours a
day, and—due to its proximity to a major business school—experiences customers arriving
around the clock. A recent analysis done by the store manager indicates that there are 30
customers arriving every hour, with a standard deviation of interarrival times of 2 minutes. This
arrival pattern is consistent and is independent of the time of day. The checkout is currently
operated by one employee, who needs on average 1.7 minutes to check out a customer. The
standard deviation of this check-out time is 3 minutes, primarily as a result of customers taking
home different numbers of videos.
a. If you assume that every customer rents at least one video (i.e., has to go to the
checkout), what is the average time a customer has to wait in line before getting served
by the checkout employee, not including the actual checkout time (within 1 minute)?
b. If there are no customers requiring…

The students patiently form a single line in front of the desk to wait for help. Students are served based on a first-come, first-served priority rule. Students arrive at the help desk at the rate of 4 every 10 minutes. The average service time is 2 minutes. The Poisson distribution is appropriate for the arrival rate and service times are exponentially distributed.arrow_forwardQuestion 4 A petrol station in the capital Kingstown has a single pump manned by one attendant. Vehicles arrive at the rate of 20 customers per hour and petrol filling takes 2 minutes on an average. Assume the arrival rate is Poisson probability distribution and service rate is exponentially distributed. Arrivals tend to follow a Poisson distribution, and service times tend to be exponential. The attendant is paid $10 per hour, but because of lost goodwill and sales, station loses about $15 per hour of customer time spent waiting for the attendant to service and order.
