RASQI is a discrete-event simulator and digital twin for your production line. Model stations, buffers, feeders and operators — then read a money-first report: bottleneck, OEE, loss waterfall, and the payback on every change. Runs in your browser — nothing to install.
● Runs in your browser · ● Validated vs queueing theory ~2% · ● No install, no IT project
Find the constraint, decompose capacity, and see the loss waterfall — what each stop costs you per year.
Compare two versions of the line with common random numbers and print the payback of the change.
Full-factorial sweeps with main-effects, a standardized-effects Pareto, and an optimization point.
A one-pager with payback, ROI, NPV and IRR — so the line decision is a financial decision.
Two minutes, two parts: watch the simulation drive your line, then read the automated diagnosis that turns it into money.
You're about to spend real money on a station, a buffer, or a second shift. RASQI lets you test the decision first — on your own line, in your own browser, in minutes.
Answer "will this investment pay back?" with numbers, not vendor promises. ROI/NPV/IRR on a single page.
A validated DES engine (M/M/1 within ~2%) with TOC/Lean/Six Sigma diagnosis. No coding, no server of yours.
Opens in any modern browser, always the latest version. The simulation computes on your machine — your line model stays with you.
Lay out stations, parallel stages, conveyors and component feeders. Run it and watch material flow, jams, starvation and blocking in real time.
The report prices every lost hour per year. The loss waterfall and automatic diagnosis tell you what to recover first — grounded in operations theory, not guesswork.
Compare scenario A to B with paired runs, then turn the gain into a financial one-pager. Payback, ROI, NPV and IRR — the language your CFO already speaks.
Traditional line simulators are expensive, complex, and need a trained specialist to operate. Most small and mid-sized factories don't have one — and don't need one.
RASQI is deliberately simpler — and for the vast majority of SME production lines, it fully covers the job. Anyone who understands the line can run a real simulation, without learning complex software.
Every line decision is one of two things: making the line you already have earn more, or building a new line that hits its target — balanced. RASQI is the rational path through both.
Buy a machine, add a shift, rebalance, expand — the expensive moves should be tested first.
A premium position is won by factories that make better, money-first decisions — over and over. RASQI turns that into a repeatable discipline anyone who knows the line can run. That's why it belongs in every operation that intends to lead.
