When waiting times cannot be observed directly, Little’s law can be applied to estimate the average waiting time by the average number in system divided by the average arrival rate, but that simple indirect estimator tends to be biased significantly when the arrival rates are timevarying and the service times are relatively long. Here it is shown that the… CONTINUE READING
