Free industrial engineering tools.
Model, simulate, optimize.

Guides, learning tracks, calculators, templates and flow games for lines, warehouses, repair shops and offices, free on the site. When the work moves to the floor, the same tools run offline from one file, with your data on your machine.

Machines, people and flow time for a production line at any rate. Starts simple; turn on detail when you need it.

  • Starts simple. Work centers, hrs and a rate. The sample and a new line open with every switch off.
  • Switches. 26 switches under Machines, People, Work Content, Parts, Speed of Material, Limits and Time. Off leaves a feature out of the math; your values wait in the file.
  • Overview. Machines, people, Max rate and flow time on one card, with the next step to try.
  • Math on click. Click a figure for its math, one line at a time. Type an input where it shows and see what moved.

Version 0.5.1. Starts simple: every switch off until your line needs it.

Every tool in one window. Every file in one folder.

Install once and the tools live on your computer like any other program. Open them from one library, and your work lands in one place you can find without searching.

  • One library. Every tool you have on one screen, tagged by group, with your recent files under each one.
  • One folder. Save writes straight to Documents\SymplProcess\<Tool>. No Save As box, no hunting through Downloads.
  • Autosave to disk. Work saves as you go, with the last 10 versions kept next to it.
  • Updates. The app and your tools tell you when a new version is out, and update when you say.
  • Offline. Tools never reach the network. Your files stay on your machine.
Download for Windows → How it works Free through November 30 during the preview. Can't install software at work? Every tool still runs as a single file in the browser.

Operations are hard. Fixing them shouldn't be another job on your list.

The line is behind, the bottleneck moved, repairs sit waiting on parts, the pack line can't keep up at peak, and the spreadsheet that was supposed to help needs its own owner. These tools start from the problem you have, on the line, in the warehouse or in the repair shop, and get you to the fix with your own numbers. No install, no IT ticket, no training course first.
