About this app

The Queueing Theory Calculator helps evaluate the performance of single-server (M/M/1) and multi-server (M/M/s) queueing systems. It computes essential performance indicators such as traffic intensity (ρ), server utilization (α), average number of customers in the system (L), queue length (LQ), average waiting time (WQ), total time in the system (W), and the probability of having a specific number of customers (Pn).

This tool is ideal for operations management, network design, and service optimization, enabling users to assess system efficiency, balance demand and capacity, and predict potential delays or congestion in service systems.
