Features
MySolvers is a browser-based discrete-event simulator for queueing systems. Build models visually, run them in real time, and read the results from live charts — all without installing anything.
Visual Model Builder
Design queueing systems on an interactive canvas. Place generators, queues, and servers, then wire them together with connections. Pan and zoom to work with models of any complexity.
Three Core Components
Build any queueing topology from three primitives: a Generator that produces entities at a configurable arrival rate, a FIFO Queue with a configurable capacity, and a Server that processes entities at a configurable service rate.
Exponential Distributions
Arrivals follow a Poisson process and service times are exponentially distributed, giving you the classical M/M/c building block for telecom, manufacturing, and service-system models.
Real-Time Simulation
The discrete-event engine runs in a background Web Worker so the UI stays responsive. Play or stop the simulation at any time, and adjust speed from 0.25× all the way to 16× to match your analysis pace.
Live Inline Analytics
Charts appear directly on the canvas next to each component as soon as the simulation runs. Track queue length over time, queue-size probability distributions, server state breakdowns (waiting / busy / blocked), and entity throughput rates.
End-to-End Cycle Time
A global monitor tracks every entity from creation at the generator to completion at the last server. A live histogram shows the distribution of end-to-end cycle times, so you can see latency percentiles as the simulation evolves.
Mid-Run Parameter Tuning
Change arrival rate, service rate, or queue capacity while the simulation is live. The engine applies your updates instantly, so you can explore what-if scenarios without restarting.
Round-Robin Routing
Fan out from one component to many consumers, or fan in from multiple suppliers to one component. The engine balances traffic round-robin, letting you model parallel servers and multi-stage pipelines.
Model Save & Load
Export your model to a file and reload it in any browser session. Auto-save keeps your work safe between visits without any extra steps.
The free Starter plan lets you try the simulator with up to five components. The Professional plan removes that limit and adds advanced analytics and file import/export.
