YourSimulationDiscrete-event simulation & optimization in your browser

Model airports, hospitals, banks, factories, restaurants, and networks — estimate waits, utilization, and throughput, and find the cheapest design that meets a service target.

Examples

12-block visual editor

Drag-and-drop sources, queues, resources, delays, resource pools (seize/release), assign, batch/separate, match, and routing — on a themed canvas.

Models the real world

Reneging and balking, join-shortest-queue and class-based routing, shared resources held across steps, preemptive priority, machine breakdowns, and assembly.

Rigorous engine

Seeded replications with 95% confidence intervals, validated against closed-form queueing theory — M/M/1, M/M/c, Erlang-A, and M/M/1 preemptive priority.

Optimize, don't guess

Cross-Entropy search finds the cheapest configuration meeting your service targets.

YourSimulation Studio ​

▶ Launch the Studio — free, in your browser →

YourSimulation Studio is the free, browser-based home for the engine — a visual model editor, experiment runner, and optimizer. No install, no account: open the page and start modeling.

  • Drag-and-drop editor — build any service / queue / network system from 12 blocks on a themed canvas.
  • Answers with error bars — seeded replications report waits, utilization, and throughput with 95% confidence intervals.
  • Watch mode — deterministic animated playback skinned for airports, hospitals, logistics, and networks.
  • Optimize, don't guess — a Cross-Entropy search finds the cheapest design that still meets your service target.
  • AI companion — a bring-your-own-key agent that proposes model edits from plain language.

Free to use — the Studio is free, and the engine underneath is open-source (MIT). Try it on a worked example: airport security, hospital triage, a bank branch, a factory line with breakdowns, a saturated restaurant, or a 100k-client CDN network — all ready to run.
