SUMMARY:The BRAVO Effect in Queues - Yoni Nazarathy (University of Queensl

DESCRIPTION:BRAVO stands for “Balancing Reduces Asymptotic Variance of O
 utputs”.  Consider for example a stationary M/M/1/K queue and study the 
 counting process of served customers.  If the arrival rate is much lower t
 han the service rate then the output process is “Poissonish”. For exam
 ple the ratio of the variance of the number of outputs to the mean number 
 of outputs is approximately unity. Similarly if the arrival rate is much h
 igher than the service rate.  But when the queue is balanced in the sense 
 that the arrival rate is approximately equal to the service rate then this
  asymptotic variance ratio is approximately two thirds.  This is BRAVO! It
  turns out that this type of puzzling behavior occurs in a variety of queu
 eing models. \n\nIn this talk we survey some results quantifying BRAVO as 
 well as other aspects of queueing output processes.
