The RASQI Line Simulator tells you what a production line will actually deliver, finds the true constraint, and prices every lost hour — so you can test a change on the model before you spend on the line.
In beta. The engine and the report are stable; the interface, languages and licensing are still changing.
● Runs in your browser · ● Engine checked against queueing theory (~2%) · ● No install, no IT project
Built for serial and assembly lines. What it does not model ↓
Each station is a card: cycle, load and unload, operators, stops, quality. Or fill the whole line in one table.
Watch the line run, or run the full horizon without animation. Cycle times vary the way your data says they do.
The report ranks the stations that limit output and prices each loss per year, biggest first.
Save the line as A, change one thing, run B. Both runs use the same random numbers, so the gain is the change and not luck.
An estimate, and the app says so: no working capital, financing, sales taxes, inflation, FX, ramp-up or residual value. Your finance function reviews the case before any money is committed.
RASQI is a focused simulator for serial and assembly lines, not a general-purpose modelling platform. Check the right-hand list before you buy.
