what measures of system performance is a key measure

average number of customers waiting in line

not generally considered as a measure of system performance in a queuing analysis

average serving time

Little's Law states that the number of people in a waiting line is the average customer arrival rate multiplied by the

average time in the system

refers to the physical presence of the customer in a service system

customer contact

As the ratio of arrival rate to service rate is increased, what is likely?

customers move through the system more slowly because utilization is increased

A single channel queuing system has an average service time of 16 minutes per customer, which is exponentially distributed. The manager is thinking of converting to a system with a constant service time of 16 minutes. The arrival rate will remain the same. The effect will be to

decrease the average waiting time

characteristic of a well-designed service system

each element of service system is consistent with the operating focus of the firm

An alternative strategy to increase the capacity of a service system is

increasing the processing rate

In the service-system design matrix, a face-to-face total customization service encounter is expected to have

low production efficiency

A customer enters a business and has the opportunity to select any one of three lines to receive service. The service is performed by one customer service representative after which the customer leaves the establishment. Which description of this waiting line system is appropriate?

multiple channel, single phase

Customer arrivals at a dry cleaning service occur randomly throughout the day. the distribution that is usually used to model the interval between arrivals is the

task, treatment, tangible

not an element of a good service guarantee

the customer controls the process

major factor that distinguishes service design and development from manufacturing design and development

the service package is the major output of the development process

The goal of queuing analysis is to minimize

the sum of customer waiting costs and capacity costs

Why is there waiting in an infinite source queuing system?

variability in arrival and service rates
