The RASQI Line Simulator tells you what a production line will actually deliver, and prices every lost hour. It comes with the three tools that surround that answer: the statistics that say whether the data can be trusted, the business case that turns it into money, and the project tool that measures whether the gain showed up.
RASQI is in beta. The Line Simulator engine and report are in daily use and validated against queueing theory — what is still moving is the interface, the languages and the licensing. The other three products are online today and included; each is used on its own.
● Runs in your browser · ● Validated vs queueing theory ~2% · ● No install, no IT project
An improvement is a chain of four questions, and getting any one of them wrong wastes the other three. A capability study on a measurement system nobody trusts. A simulation fed by numbers someone guessed. A business case that was never checked against what actually happened. Each product owns one question — and only one. You buy the Line Simulator; the other three come with it, not as trial versions or feature-limited editions, but as the full products behind the same sign-in.
You don't juggle four logins and four bookmarks. Buying takes you to the RASQI Hub: one sign-in, and from there you open any of the four. It also shows the improvement cycle laid out, so you can see which product answers the question you have today.
It is a launcher and a map — deliberately not a dashboard. It never repeats a number another product calculated, because a figure shown away from the conditions that produced it is a figure waiting to be misread.
One question, one owner. Capacity comes from the simulator, statistics from 6Sigma Studio,
the financial verdict from the Analyzer, the measured gain from the Project Manager. Whoever
receives a number shows it — nobody recomputes it, because two implementations of the same
calculation diverge, and they diverge on the hard case.
Today each product is used on its own and you carry the number across.
The direct hand-off between them is being built; when it ships it will be announced here, not before.
Every claim on these cards was checked against the product's own source code or test suite before it was written here. Where a product doesn't do something, the Capabilities page says so.
Everything you need to model a line, find the constraint, and put a number on 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 a recommended optimum — plus an automatic improvement study that sweeps the two biggest losses and the constraint's cycle time.
Payback, ROI, NPV and IRR on a single page — turn an operations change into a financial decision. The full business case belongs to the Investment Analyzer, and the one-pager says so.
Component feeder lines and multi-product recipes/campaigns model the real bill of materials, not just a single flow.
Seven cycle-time distributions with auto-fit, plus breakdowns, jams, starvation and blocking — realistic, not deterministic.
The recording travels as events, not frames — so you can speed up to 300×, pause, drag back and watch the same jam again at 1×, without asking the server anything.
Opens in any modern browser, always the latest version. The simulation runs on a secure server; your financial configuration — prices, margins, demand — is never sent.
Two minutes, two parts: watch the simulation drive your line, then read the automated diagnosis that turns it into money.
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 among those tested.
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.
The simulator says so itself: this is an engineering estimate for screening and prioritisation — it carries no working capital, no financing, no sales taxes, no inflation or FX, no ramp-up and no residual value. When the number has to survive an investment committee, that is what the Industrial Investment Analyzer is for, and it is in the box.
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 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.
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. 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.
Answer "will this investment pay back?" with numbers, not vendor promises — from a screening one-pager in the simulator to a full incremental business case in the Analyzer.
A validated DES engine (M/M/1 within ~2%) with TOC/Lean/Six Sigma diagnosis — and the statistics to check your inputs before you trust the output. No coding, no server of yours.
Opens in any modern browser, always the latest version. Nothing to install, nothing to host — and your saved lines, cases and projects stay in your browser, not in our database.
All four products, in your browser. No install, no card, no IT project. RASQI is in private beta, so access is by request while we finish it.
