QueueSim

QueueSim runs a discrete event queueing simulation, so the numbers in Claude's answers come from a real engine run on your inputs, not from a guess. Ask how many staff a line needs, what the wait will be at the lunch rush, or what adding one server would change, and Claude runs it. What it can do: - Simulate a queue from arrivals per hour, service rate and number of staff (simulate_mmc) - Find the smallest staffing that meets a wait target (recommend_staffing) - Run a full 24-hour day of arrivals and shifts, hour by hour (simulate_schedule) - Compare one shared line against separate lines (compare_separate_vs_pooled) - Check the engine against the closed-form Erlang C formula, side by side (compare_analytical_vs_simulated) - Start from four sample scenarios: single server, coffee shop, grocery checkout and call center Who it's for: people who staff lines, such as call centers, help desks, retail checkout and service counters. Free, no account, and read-only. Every result lists the inputs that produced it, so you can check it and run it again. For systems beyond one line (several steps, shared staff, routing, priorities, customers who give up), QueueSim Cloud at https://app.queuesim.com builds and runs those models. Made by ChiAha.
