Stationline: free online line balancing and layout tool

Stationline balances a single-model assembly line in your browser. Enter the available time and the demand to get the takt time, list the tasks with their times and the tasks that must come first, and Stationline assigns them to stations with three priority rules at once. It reports stations, efficiency, balance delay and smoothness, and for small lines it can prove the fewest stations possible.

The same project holds a grid facility layout scored by flow cost or by an adjacency chart, a basic value-stream calculation with lead time and process cycle efficiency, and stopwatch time studies with ratings and allowances. A study can set a task time and a balanced station can set a stream step, so the views stay consistent. Nothing is uploaded; the Guide states the limits and the Verify page runs the reference checks in your browser.

What Stationline can do

• Balance a precedence-constrained line with three priority rules and a proven-minimum check for small lines
• See takt time, efficiency, balance delay, smoothness index and the precedence diagram with stations marked
• Score a grid layout by flow cost or by an adjacency chart, with a best-possible search for small plants
• Compute value-stream lead time, process time and process cycle efficiency from the same takt time
• Turn observations, ratings and allowances into normal and standard times, work-sampling intervals and learning-curve times
• Exchange open JSON and CSV files and export SVG or PNG drawings

How we verify Stationline

Stationline is checked on distinct properties against independent code, hand derivations and a published statistical table; the Verify page lists every case with its method and source, and you can run them in your browser. Pending sources do not count as passes. Passing them does not certify a production line, a layout or a labour standard, and results must be checked by a qualified professional. Where a reference answer exists you can run every check yourself on the Verify page, and the Stationline user guide documents every feature and limitation.

Stationline is part of Open Tools, the free engineering tools that run in your browser.
