To better understand what stochastic model might be appropriate in applications with system data, we study the consequences of fitting a stationary birth-and-death (BD) process to the sample path of a periodicmodel. The fitted BD process will necessarily have the correct steady-state distribution (appropriately defined), but will not have the correct transient behavior. Nevertheless, the fitted birth-rate and death-rate functions have structure determined by themodel that should be seen with data if themodel is appropriate. In this paper, we establish heavy-traffic fluid limits that yield explicit approximation formulas for the fitted birth-rate and death-rate functions that can help evaluate whether a periodicmodel is appropriate. We also establish many-server heavy-traffic fluid limits for the steady-state distribution in the periodicmodel. For the special case of sinusoidal arrival rates, the limiting steady-state distribution has an arcsine law.
