Question

A call center wants to determine how many customer representatives to hire. An average of 80 calls per hour is estimated to have. Interarrival times are exponentially distributed. Each customer representative’s service time is assumed to be exponentially distributed with mean 1.5 minutes and her service time costs $6 per hour. Waiting of a customer on line is estimated to cost $24 per hour. Determine the optimum number of representatives to hire.

Answer #1

**Answer:-**

**Given that:-**

A customer service center has customers call with questions
about the use of a product. The mean arrival rate of customer calls
is 20 per hour and follows a Poisson distribution. The mean service
rate (how long it takes the call center employee to answer the
customer’s question) is 30 customers per hour (most customer
questions can be answered rather quickly) and follows an
Exponential distribution.

On the average, there is one new customer calling in to a call
center every 20 minutes. Assume the
number of calls follows the Poisson process.
(a) What is the probability that in the next 40 minutes, exactly 3
new customers will call?
(b) What is the probability that there are no calls in the next
hour?

Calls to a customer service center last on average 1.95 minutes
with a standard deviation of 1.63 minutes. An operator in the call
center is required to answer 75 calls each day. Assume the call
times are independent.
Round answers to 3 decimals.
(a) What is the expected total amount of time in minutes the
operator will spend on the calls each day?
(b) What is the standard deviation of the total amount of time in
minutes the operator will...

Consider a troubleshooting call center, where customers wait on
hold until a representative is available. Currently, there are six
representatives on duty at any one time. A representative talks
with a customer for an average of 16 minutes. Records show that
average time for a customer to wait on hold is 36 minutes. a. On
average, how many customers are on hold for the entire call center?
Show all work. b. If the service were improved so that the average...

An automatic roller coaster ride takes a constant time of 2.5
minutes to complete a ride. Customers arrive at the facility every
2.75 minutes (exponentially distributed). Report answers to 4
decimal places.
a. Determine the average waiting time in the queue (in
minutes).
b. The local bank drive-through teller window can serve a
customer at an average of 4.5 minutes per customer (exponentially
distributed). Customers arrive in their cars at a rate of 12 per
