Production rate calculations..

[Mr. Tact]

I recently added the "Late Upgrades" mod to get some demand going on my factory. So, I build a new research area, in which I built, among other things, 60 Labs and 10 Level Assembly Machine 3s making Science Pack 1s. So, ignoring the crafting bonus for the level 3 assembly machine, that should be 2 packs a second, right? 5 secs a piece, 10 assemblers, 2 per sec.

I was researching something which every 90 seconds required 2 science pack 1s, 1 science pack 2s, 1 science pack 3s, and 1 alien science pack. So, that would seem to mean 120 science pack 1s every 90 seconds. In 90 seconds, I should be producing 180 science pack 1s. Yet, my production could not keep up with the usage. What am I missing/overlooking?

Suggest sending us the save and/or images. Lots of things might be wrong.

You did the calulations Wrong.
You don't have enough resources to supply the assemblers.
Your belts/inserters cannot keep up
You don't have enough power.

Need more details.

[Mr. Tact]

It is all express belts and fast inserters. And I have literally 10 times the power I need -- I went a little crazy with my solar. The materials to assemblers do not run down, every assembler has plenty of materials. But here is a screenshot.

The 60 labs are just to the north...

have you researched the lab efficiency upgrades. they change the time it takes but the tech info doesn't update to reflect the speed increase

[Mr. Tact]

Ah, thank you. That makes perfect sense -- this is almost certainly the cause. I knew I must be overlooking something.

[Mr. Tact]

What, no critique or compliment on my layout? You guys are slipping.

[AutoMcD]

Not terribly compact but it's not like land is scarce. Clean and simple is good.
