Arrival Rate

Arrival rate refers to how many entities, such as customers, phone calls, or shipments, arrive at a particular place or system within a specific period of time. It helps measure the flow or volume of arrivals, allowing organizations to plan staffing, resources, and capacity effectively. For example, if a store receives 50 customers per hour on average, its arrival rate is 50 customers/hour. This metric is important for managing wait times and ensuring smooth operations, especially in systems where the rate can fluctuate over time.
