> you don't want to find out that you're out of stone when your bots stop autoreplacing your walls and the biters flood inīut stone is used in more than just walls. especially with fuel cells, I like to have at least a two hour supply, in case setting up the next mine is nontrivial.ĭisclaimer: I have played several hundred hours of factorio, but I have never built a base so large that my PC itself became the bottleneck. I usually maintain fairly deep buffers of critical defense items and monitor them periodically (or set up alarms). it's a real pain to reseed your kovarex enrichment in a power crisis. you don't want to find out that you're out of stone when your bots stop autoreplacing your walls and the biters flood in, or discover that you've exhausted all your uranium patches when your base goes dark. certainly no one would implement a buffer knowing at the time that it was unnecessary!īut even in factorio, it can be worth maintaining a buffer deeper than what's needed to keep the factory running at 100% under optimal conditions. This is sort of tautological, or at least hinges on how you interpret "necessary". It means eliminating unnecessary buffers. > Just in time doesn't mean "buffer free". Buffer size 50 (minimum size allowed on chests) are used in practice. but anything more than that is redundant. Maybe 24 or 36 so that you have enough buffering to handle 2 or 3 swings of the stack inserter in case those items don't arrive on time (bots "seemingly randomly" run out of power, from the perspective of that assembly machine). The key buffer size is usually 12 (the stack-inserter's grab size). The size of these buffers are grossly larger than what anyone needs. A long belt 1000 tiles long would force you to buffer up 7000 (one side) or 14,000 items (double-sided). and proportionally to the size of the belt. There's no reason to buffer-up 1000x items when 20-sized buffers work out fine.īelts force you to buffer everywhere. At that point, you realize that smaller buffers are more efficient, and that larger-buffers don't do anything.Įx: if you achieve maximum throughput with buffer-size 20, you leave it at 20-sized buffers. When you go bot-based, you have full control over the size of your buffers at all steps of your Factorio design. That means that Ford had a 2-month buffer _in practice_. ) because of its "just-in-time" process, Ford was able to give 2-months of notice before shutting down one of its lines.
