The single-server model assumes that customers arrive randomly over time, with the variability of customer arrivals most often described by a Poisson distribution. This means that there is no pattern to customer arrivals - they can come in bursts or at steady intervals - but on average the number of customers arriving in a given time period is predictable. The Poisson distribution is commonly used to model random events with a low probability of occurrence but a large number of potential events (such as customer arrivals).
