What benefits do psychological approaches to waiting lines have over other approaches?


. Consider this situation: A manager is contemplating making changes to a single-server system that

is expected to double the service rate, and still have just one server.

a. Would you (intuitively) think that doubling the service rate of a single-server system would cut

the average waiting time in line in half?


b. For the sake of analysis, suppose the current system has an arrival rate of 8 customers per hour

and a service rate of 10 customers per hour. If the service rate is doubled, what impact will that

have on the average number waiting in line?


c. What are some managerial implications of your analysis?
