Factorio Forums

I'd like to design a ore+oil -> rocket part factory with ratios as close as possible to optimal, assuming productivity modules wherever allowed and (e.g.) 2 speed beacons per assembler.

Is there any tool for doing the necessary calculations? I guess I can roll my own spreadsheets, but there seem to be a number of nice calculators, but some seem outdated and none that I can see allow for productivity and speed modules, which change the ratios in a non-trivial way...

Productivity modules might be interesting - I haven't used them much, but they can make quite a difference if used for high-level items like rocket control units, since the ingredient requirements get lower throughout the whole chain.

Thanks for giving me that idea, I've now added support for productivity modules to my spreadsheet: https://docs.google.com/spreadsheets/d/ ... ado_K2JbXc (edit - it already supports speed modules)

It still doesn't support beacons, though. That wouldn't be hard to add, but the number of speed combinations would make the spreadsheet a bit unwieldy.

I felt the same way with the modules, just finished putting together a spreadsheet for them. You can add in beacon modules too, just have to divide by 2 because of the .5 distribution efficiency.

Almost finished. Full chain with calculation of cost, production and even excess. It's more comfortable for me to use it than flowcharts, dunno why. That's why I've made it.
