Support Queue: Staffing & Wait-Time Simulator

Interactive Erlang-C queueing simulator for a mobile app support desk: tune ticket arrival rate, agent headcount and handle time, and watch tickets queue, get served and resolve in 3D while live stats track wait time and SLA compliance against the theoretical prediction.

Mobile-app customer support lives or dies on one number: how long a ticket waits before an agent picks it up. This simulator runs a real M/M/c queueing model — tickets arrive as a Poisson process, a bank of agents serves them at an exponential rate, and a single FIFO line holds whatever cannot be answered immediately. Drag the arrival rate, agent headcount, average handle time and SLA target and watch tickets stream in, queue, get served and resolve in 3D, while live readouts track the measured average wait and percentage answered within SLA against the closed-form Erlang-C prediction for the same parameters — the exact staffing math real support and call centers use to size a team against a promised response time.
