Question

Customers arrive at a common queue at the coffee station with
two identical coffee machines in a busy mall at the rate of 48 per
hour, following Poisson distribution. Each customer mixes his or
her specialty coffee taking 2 minutes on an average following an
exponential process. What is the expected number of customers in
the system at this coffee station?

Answer #1

6. Consider a queueing system having two servers and no queue.
There are two types of customers. Type 1 customers arrive according
to a Poisson process having rate ??, and will enter the system if
either server is free. The service time of a type 1 customer is
exponential with rate ??. Type 2 customers arrive according to a
Poisson process having rate ??. A type 2 customer requires the
simultaneous use of both servers; hence, a type 2 arrival...

(4) In a shop there are two cashiers (A and B) with a single
queue for them. Customers arrive at the queue as a Poisson process
with rate λ, and wait for the ﬁrst available cashier. If both
cashiers are available, they pick one equally likely. Each cashier
ﬁnishes with a customer after an exponential waiting time, with
parameters µa and µb for cashier A and B, respectively. Assume that
λ < µa+µb. (a) Formulate a Markov chain model with...

Customers arrive at a two-server system according to a Poisson
process having rate λ = 5. An arrival finding server 1 free will
begin service with that server. An arrival finding server 1 busy
and server 2 free will enter service with server 2. An arrival
finding both servers busy goes away. Once a customer is served by
either server, he departs the system. The service times at server i
are exponential with rates µi, where µ1 = 4,
µ2...

Individual customers arrive at a coffee shop after it opens at 6
AM. The number of customers arriving by 7AM has a Poisson
distribution with parameter λ = 10. 25% of the customers buy a
single donut and coffee, and 75% just buy coffee. Each customer
acts independently. Answer the following:
a.What are the two random variables described above and what are
their probability
mass functions?
b.What is the probability that exactly five customers arrive by
7AM?
c.If 10 customers...

Customers arrive at bank according to a Poisson process with
rate 20 customers per hour. The bank lobby has enough space for 10
customers. When the lobby is full, an arriving customers goes to
another branch and is lost. The bank manager assigns one teller to
customer service as long as the number of customers in the lobby is
3 or less. She assigns two tellers if the number is more than 3 but
less than 8. Otherwise she assigns...

Case Study: Pantry Shop (modified)
Customers arrive at the Pantry Shop store at a rate of 3 per
minute and the Poisson distribution accurately defines this rate. A
single cashier works at the store, and the average time to serve a
customer is 15 seconds, and the exponential distribution may be
used to describe the distribution of service times.
What are λ and μ in this situation?
Using Kendall notation, what type of queuing system is
this?
How many minutes...

(Operations Management) A residential
construction company has opened a registration office. Customers
arrive at the rate of 200 per hour (Poisson Distribution) and the
cost of their waiting in the queue is estimated $100 per person per
hour. The local convention bureau provides servers to register
customers at the fee of $15 per person per hour. Registration
process takes 1 minute (Exponential Distribution) and a single
waiting line, with multiple servers is set up.
a) Compute both the minimum and...

Customers arrive at a two server system at an exponential rate
10 customers per hour. However, customers will only enter the
resturant for food if there are no more than three people
(including the two currently being attended to). Suppose that the
amount of time required to service is exponential with a mean of
five minutes for each server.
(a) Write its transition diagram and balance equations.
(b) What proportion of customers enter the resturant?
(c) What is the average...

Exercise 11.2.5 Customers arrive at Bunkey’s car wash service at
a rate of one every 20 minutes and the average time it takes for a
car to proceed through their single wash station is 8 minutes.
Answer the following questions under the assumption of Poisson
arrivals and exponential service.
(a) What is the probability that an arriving customer will have
to wait?
(b) What is the average number of cars waiting to begin their
wash?
(c) What is the probability...

A large bank branch employs 5 tellers to serve its customers.
Customers arrive according to a Poisson process at a mean rate of 3
per minute. The transaction time between the teller and customer
has an exponential distribution with a mean of 1 minute. The
management has established the following guidelines for the
satisfactory level of service to customers:
The average number of customers waiting in line to begin
service should not exceed 1.
At least 95% of the time,...
