1) In a service system with impatient customers, is 1/a (1/interarrival time) the same as the flow rate? please explain.

What is flow rate ?
- The number of flow units,
for example-customers, money, produced goods or services going
through the business process per unit time, for example- served
customers per hour or produced parts per minute. The flow rate is
an average rate. It is also called as throughput.
Flow rate formula - Inventory/Flow time
If a company produces 1000 chaires in 10 days.
1000/10 = 100 chairs ( Flow rate)
What is interval-arrival time ?
-
If 12
customers enter a store per hour, the time between every arrival
is-
1/12= 0.083 hours.
0.083 hours multiplied by 60 minutes = 5 minutes.
It means the
arrival rate of 12 per hour, the time between each arrival is 5
minutes.
From the above 2 examples, it can be observed that both of
them are similiar in formula but interval-arrival-time is
calculated in time units (minutes) . Whereas, flow rate is
calculated in of number of units produced in particular period of
time.

Customers arrive at a service center according to a Poisson
process with a mean interarrival
time of 15 minutes.
If two customers were observed to have arrived in the first
hour, what is the probability that at least
one arrived in the last 10 minutes of that hour?

There are 3 servers in the checkout area. The interarrival time
of customers is 4 minutes. The processing time is 10 minutes. The
coefficient of variation for the arrival process is 1 and the
standard deviation of the processing times is 20 minutes. What is
the average number of customers that are waiting?

In a drive-thru fast food restaurant, customers arrive with an
interarrival time of 6 minutes. The drive-thru operates in just a
single file line so only one customer’s order is processed at once.
The drive-thru has an average service time of 4 minutes.
What is the steady-state utilization of the drive-thru? What is
the average time in system per customer? What is the probability of
there being exactly 1 customer in the queue?

An aircraft repair service reimburses its customers for the time
that an aircraft spends at their facility. Total costs are the sum
of these reimbursements (waiting costs) and the salaries of their
technicians. A customer is reimbursed $203 per hour for the time
that the aircraft is out of service, and the cost of a service
technician (including equipment and materials) is $1,196 per hour.
Use Table 1 and Table 2. a. How many service technicians should be

1. A bank manager has developed a new system to reduce the time
customers spend waiting for teller service during peak hours. The
manager hopes the new system will reduce the waiting time that
currently is 10 minutes.
a) Formulate the hypotheses and rejection rule for this
problem.
b) A random sample of 70 waiting times was obtained after the
system was implemented. The sample showed a sample mean of 9.5

1. A bank manager has developed a new system to reduce the time
customers spend waiting for teller service during peak hours. The
manager hopes that the new system will reduce waiting times from
the current average of 7 minutes. Assume that the population
standard deviation for waiting times is 2.47 minutes. The manager
takes a random sample of 100 waiting times and finds that the
average waiting time for the sample is 5.46 minutes. Conduct a
hypothesis test to...

At an inside sales counter an average of 20 customers enter the
system for service each hour, it takes about five minutes to serve
each customer. The manager has been staffing the counter with three
sales associates. She wonders if she should reduce the staffing
level to two. What is the probability that more than two people
enter the system in a five-minute period? What about more than
4?

Two mechanics are changing oil filters for the arriving
customers. The service time has an Exponential distribution with
mean 12 minutes for the first mechanic, and mean 3 minutes for the
second mechanic. When you arrive to have your oil filter changed,
your probability of being served by the faster mechanic is 0.8.
