A service counter employs two servers. On average, a server requires 8 minutes to process a customer and service times follow an exponential distribution. Customers arrive at the counter at the rate of 12 per hour according to a Poisson distribution. On average, the total number of customers in the system (i.e., waiting and being served) would be

A teacher is an example of a

The service-process matrix is based on two characteristics: labor intensity and volume.

In a waiting line system, the ___________ reflects the probability that the server is busy and the customer must wait.

The number of channels in a queuing process

In general, as the number of servers in a waiting line system increases,

A service package defines the target market and the desired customer experience.

Which of the following is not a basic element of a waiting line?

A small diner has one employee and a counter with seating for 8 customers. The diner does not package food for takeout. Customers arrive at the diner at the rate of 20 per hour (Poisson distributed) . Service times are exponentially distributed and average 24 per hour. Customers that arrive when all seats are taken do not enter the diner. What is the average time a customer spends waiting?
