Exam 7: Service Design

Consider an espresso stand with a single barista.Customers arrive at the stand at the rate of 28 per hour according to a Poisson distribution.Service times are exponentially distributed with a service rate of 35 customers per hour.The probability that the server is busy is

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 in the diner?

Which of the following is not a characteristic of a service?

If,on average,it takes 90 seconds to serve a customer then the hourly service rate,µ,is

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

Waiting lines form because customers arrival times and service times are not always equal.

Almost all consumer products consist of some combination of facilitating goods and facilitating services.

The calling population is the source of customers used in waiting line analysis.

Consider an espresso stand with a single barista.Customers arrive at the stand at the rate of 28 per hour according to a Poisson distribution.Service times are exponentially distributed with a service rate of 35 customers per hour.The average time in minutes a customer spends in the system (i.e. ,waiting and being served)is

What is a calling population in terms of a waiting line system?

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 number of customers in the diner?

If the average service rate is smaller than the average arrival rate an infinitely large waiting line (queue)will form.

Consider an espresso stand with a single barista.Customers arrive at the rate of 20 per hour according to a Poisson distribution.Service times are exponentially distributed with a mean service time of 2 minutes per customer.What is the service rate per hour for the espresso stand?

Waiting lines form only when service operations are understaffed.

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.The average amount of time,in minutes,spent in the system (i.e. ,waiting and being served)is approximately

The number of arrivals per unit time to a service facility is often described by a Poisson distribution.

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.The average amount of time spent by a customer waiting in line is approximately

Consider an espresso stand with a single barista.Customers arrive at the stand at the rate of 28 per hour according to a Poisson distribution.Service times are exponentially distributed with a service rate of 35 customers per hour.The probability that there are more than 2 customers in the system is

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

The ________________ is the source of customers for a waiting line system.
