The arrival rate in queuing formulas is typically expressed as the mean number of arrivals per time period. This is because queuing models aim to predict the average number of customers arriving per unit of time, which is the arrival rate. The mean time between arrivals (option A) is related to the arrival rate, but it is not the same thing. The minimum number of arrivals per time period (option B) is not a useful metric in queuing models because it does not provide information about the variability or distribution of arrivals. The mean number of arrivals per server (option C) is not relevant to the arrival rate, as it describes the service rate rather than the arrival rate. Therefore, option D is the best choice.
