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
Everything you need to model a line, find the constraint, and prove the payback — online, in your browser.
Event-driven simulation of stations, buffers, parallel stages, conveyors and operators. Validated against M/M/1 queueing theory within ~2%.
Identifies the true constraint, decomposes capacity, and applies Theory-of-Constraints reasoning to what to elevate first.
Breaks availability/performance/quality losses into a per-year money waterfall so you fix the expensive losses first.
Paired runs with common random numbers isolate your change from luck — and print its payback.
Parameter sweeps with main-effects, standardized-effects Pareto, and an optimization point with constraint-elevation advice.
Payback, ROI, NPV and IRR on a single page — turn an operations change into a financial decision.
Component feeder lines and multi-product recipes/campaigns model the real bill of materials, not just a single flow.
Cycle-time distributions (Normal, and more), breakdowns, jams, starvation and blocking — realistic, not deterministic.
Opens in any modern browser, always the latest version. The simulation computes on your machine — your line model stays with you.
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.
Model the line, run it with real variability, test your change, and read the payback. No code, no consultant, no install.
Lay out stations, parallel stages, buffers, conveyors, operators and component feeders — all configured in modals, no code. Press play and watch material flow, with jams, starvation and blocking in real time.
Watch flow, jams, starvation and blocking — or run without animation for speed. Statistical distributions on every cycle make it realistic, not deterministic, so the gap between the plan and reality shows up.
Set up scenario A vs B with common random numbers to isolate your change from luck, or sweep parameters with a full-factorial DOE to find the best configuration.
The executive one-pager and financial study price everything per year and tell you the payback — in the language your CFO already speaks. Exportable to PDF, CSV and Excel.
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.
RASQI is a focused discrete-event simulator for serial and assembly production lines, not a general-purpose modeling platform. That focus is why anyone who knows the line can run it in minutes — and it means some line types sit outside its scope. Here's the honest boundary, so you can tell before you buy.
Your line somewhere in between? Tell us about it — we'll say honestly whether RASQI fits as-is, or scope a customization for your specific process.
Buy a machine, add a shift, rebalance, expand — the expensive moves should be tested first.
