Customers arrive at a two-server system at a Poisson rate λ=5.
An arrival finding the system empty is equally likely to enter
service with either server. An arrival finding one customer in the
system will enter service with the idle server. An arrival finding
two others will wait in line for the first free server. The
capacity of the system is 3. All service times are exponential with
rate µ=3, and once a customer is served by either server, he...
A queueing system serves two types of customers. Type 1
customers arrive according to a Poisson process with a mean rate of
5 per hour. Type 2 customers arrive according to a
Poisson process at a mean rate of 3 per hour. The
system has two servers, both of which serve both types of customer.
All service times have exponential distribution with a mean of 10
minutes. Service is provided on a first-come-first-served
basis.

Customers arrive at a two pump system at Poisson rate two per
hour. An arrival finding the system empty is equally likely to
enter service with either pump. An arrival finding one customer in
the system will enter service with the idle pump. An arrival
finding two others in the system will wait in line for the first
free pump. An arrival finding three in the system will not enter.
Two service times are exponential with rates one per hour...
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...
Suppose that customers arrive at a bank at a rate of 10 per
hour. Assume that the number of customer arrivals X follows a
Poisson distribution.
A. Find the probability of more than 25 people arriving within
the next two hours using the Poisson mass function.
B. Find the probability of more than 25 people arriving within
the next two hours using the normal approximation to the
Poisson.
C. Compute the percent relative difference between the exact
probability computed in...
5. Suppose that the customers arrive at a hamburger stand at an
average rate of 49 per hour, and the arrivals follow a Poisson
distribution. Joe, the stand owner, works alone and takes an
average of 0.857 minutes to serve one customer. Assume that the
service time is exponentially distributed. a) What is the average
number of people waiting in queue and in the system? (2 points) b)
What is the average time that a customer spends waiting in the...
Customers arrive for service at a rate of 50 an hour and each
server can deal with 25 customers an hour. There are three servers.
If the customers time is valued at $20 an hour and server time
costs $30 an hour, how much does the queue cost for an eight hour
day?
