Industries Ratios

[Alien]

So in true Factorio style, Cities Skylines now has supply chain management, I was going to make a table, but the wiki beat me to it. Pro tip: If you use ratios your profit margins and the efficiency of your industrial ares will skyrocket. We all know you can place like 300 oil pumps and have 1 Naptha Cracker Plant and have it work, but you will lose your a## in negative profit margis. Here's a link to the wiki's table! https://skylines.paradoxwikis.com/Supply_chain

Happy smog creation fellow industrialists!

So I looked at the table and I'm still a bit bewildered by it. What I want to know is, and what I don't get out of the table, if I have x units of raw materials, how much processed materials would I get out of them?

You just need to do simple math on each table row ...
example:
Flour Mill ... Crops: -2.4 (means 2.4 tons needed) ... Flour: 4 (= 4 tons produced)
-> each ton of crops produces 4 / 2.4 tons of flour (= 1.67)
-> each ton of flour needs 2.4/ 4 tons of crops (= 0.6)

Here another example from the table with the unique factories:
Lemonade Factory ... Crops -4.8 ... Glass -3.2 ... Goods 3.2
-> Each ton of Lemonade needs 1 ton of glass and 1.5 tons of crops

+1

It tells you on the processor factories.

Same with goods. The unique factories tell you. You just need to do the math backward.

So (I beg your indulgence) if I have 19,360 units of ore, which makes for normal consumption of 15.488 tons/week--

I need raw storage of 38.976 tons/week; each ore storage field can hold 400 tons, so i would only need one such field--

And 15.488 tons of ore produce 15.488 tons of metal and/or glass (-3.2 ore over 3.2 glass = 1) from ore grinding mills and/or glass manufacturing plants each at 3.2 tons per week => 5 mills and/or plants to keep up--

This makes (-3.2 tons/6.72 goods =) .476 x 15.488 tons of metal and/or glass = 7.372 tons for the electronics factory (6.720 tons/week) and/or the steel plant (6.4 tons/week)--

So I need more ore?



Thanks for your help in advance.

Why would you need more ore?

In your case it is even more straightforward:
You need 3.2 metal and 3.2 glass per week (at normal production) for an electronics factory
-> 6.4 ore with the basic steel mill and glass producer
if you also have a steel mill, you additionally need 6.4 metal/wk -> 6.4 t ore

for a total of 12.8 tons ore / week needed ... less than you produce (15.488 tons / week)

To satisfy this demand (with factories at normal speed) you would need to build
1 glass manufacturer and 3 ore grinding mills

Of course this doesn't account for any delays during transport ... if you want to be more on the save side, you would actually better have 4 ore grinding mills and 2 glass manufacturers in order to overproduce a little bit ... in which case you would need 19.2 tons of ore per week and may actually need to build another small ore mine or something like that (or cover the overhed via imports)

It also doesn't satisfy the demand of plastic for your electronics factory, of course
