A quick guide to Industry and Supply Chain rule.

[JustaGamer]

The last couples day I noticed quite a few people claiming Industry doesn't work, or bug, or they can't stop their industry from exporting. As someone who had build 8 Industry area all reach max level, I can assure you it does work, you just have to understand how it works. And supprisingly, the logic behind the DLC is based on real life logic.

First: let me define a few terms I will use to clear up confusion:

- Resource extractor (RE): the building that generate the raw resources.
- Resource dropof point (RDP): the 'defaut' warehouse you found under each industry type, and store only the raw resource of that industry type.
- Warehouse (WH): these are the 4 customizable warehouse that are in their own seperate catagory.
- Refinery (RF): factories that consume raw and turn them into materials.
- Factory (FA): the end chain factories that product luxury products from materials.

Second: the most important thing - leave every warehouse setting at Balance. The other two option Filled and Empty have very limited use for micromanagement, and frankly pass that first few factories it becomes a nightmare. As long as you set up your chain correctly, balance is sufficient. In fact I have a suspicious idea the people who are having problem are the one trying to fiddle with this setting


Third: the rules

- The supply chain only move in one direction: it means the trucks regardless of where they come from, will only do delivery, not fetch. Just like in real life, the sellers is always the one bring the product to the buyer, the buyer not gonna send their own vehicle to pick it up from the seller. It mean:

+ RE will send truck to RFs, or WH, or export it.
+ WH will send their truck to RE / FA or export it.
+ RF will send their truck to WH / FA or export it.

- Only raw resource can be imported, all material must be produced locally. All can be export.
------------------------------------------------------------------------------------------------------------------------

It sounds like a lot, but to apply them you only need to follow a couples simple rule:

- Keep the layout in one direction. (don't put your RDP after your RF)

- IMPORTANT: try to keep your RE and RDP on the same lane of traffic, so they don't have to loop. Most people use one way road anyway, but I had found that I have no problem with 2-way lanes as long as I'm being smart about it, it's also less spaghetti and headache. In another words: don't put your RE one one side and your RDP on the other side of the road. You may think "oh it's just across the street" but it means your trucks will have to do a big loop for their delievery, and might decide to just export it.

- Have WH as the final stop for your chain, and let them do the long distance delivery (export/commercial). If you see trucks from your non-WH facilies on the other side of the map, you're doing it wrong. Another suspicious of mine is people are probably ignoring this type of warehouse, and end up having all of their factories's trucks all over the map. Trust me, I did the same on the first day I played the DLC.

The idea is you want trucks from your RE, RDP, RF going as little as possible. Not only it helps with traffic, it also help with keeping the chain working at max productivity. If your RE, RDP have to send all of its truck to the other side of the map, they won't be around to delievery the raw to your factories when they need, that's why you see them having to import. The picture below is my most recent/compack oil zone.

Red: RE zone.
Blue: RDP zone.
Green: RF zone.
Yellow: WH zone.

As you can see,

- The entire chain is on one lane of traffic. Minimizing distance. Most of my building only send out 1-2 trucks at a time.

- Since I produce a lot of raw, some of the RDP still exporting them (the one closest to the RE). This is fine because it's the RDP truck that exporting, not the RE truck. While the other RDP (the ones closer to the RF zone) take care of my local need.

The idea of this set up is your RF will always get first pick for service, and the export is only what excess. That's why it's recommend you have at least 3-4 RDP, not ONE or TWO! The reason is with balance setting, some of the first couple RDP still gonna export, and might end up sending all their truck out to farcorner of the map. Having a couple more RDP further down will ensure you have a supply fleet locally.

Also, by having those WH at the end (in this case to collect products from the RF zone), I prevent any back flow traffic. Those WHs always send out all of their truck for exporting/delivering to other zone, and those traffic are kept OUTSIDE of my industry zone.

Here is a the output screenshot of the zone above + two other zone. As you will see, they all hight level with large output, and all use 100% local supply:

---------------------------------------------------------------------------------------------------------------

Two common mistakes:

One: not having enough RDP.

- I have seen people suggested set RDP to empty. DON'T DO THIS. Only thing this accomplished is to have your trucks going to far corner of the map.

- If you feel you are producing more than enough raw and yet your RF still importing. Good chance you don't have enough RDP. Because what happening is your RE are overflowing them too fast, which cause the RDP to send out all of its truck for export. And also once they ran out of space to drop, your RE truck also end up exporting. This end up leaving your RF starve of resource, not because you don't have them, but because there is no truck from your RDP or RE around to delievery for them. Remember, RF and FA can not fetch resource by themselves.

- I think what most people do when facing with this situation is instintly add more RE. This WILL NOT help your problem, in fact it gonna make it worse.

- Very easy to fix: add a couple more RDP closer to the RF zone, and your problem will dissapear. The best way to gauge whether you have enough RDP or not is to check your REs, most of them should not have to send out more than 1-3 trucks at a time.

Two: having yoru chain on the same lane.

- Can't stretch this enough. Remember "close" is not just a matter of proximity, but lane distance. A RE on one side of the road an RDP right across the street are technically "next to each other" in term of proximity, but it could very well mean a truck from your RE having to do an entire loop around your zone in order to get to your RDP.

If you hae question, let me know. Or if someone want to use this text as a basic for a more formal guide, go ahead.

Good advice OP. I too had issues early on. I found, in my case, all I needed was RDP, which initially I didn't have, and everything was being exported and factories were starving. Once I plopped a few RDP's around everything started working and I now have all industries and all at 5-star, and all the FA's, and everything works VERY WELL. :)

Yes,its a joy to watch a city operate like that,especially the traffic control,just used the 8 lane roads or 6 lane 1 ways to make it work in the industrial areas.Started a new city now and are implementing what i have learned in a better way,one major thing i learned,dont use generic industries for raw material production,oil,forestry,farms and mines,using generic for goods is fine.The problem with generic raw materials is that my level 5 buildings order from any raw meterial producer,so you have no control over where the stuff gets ordered from,most of the time they order from like the other side of the map,timed it once,took like 5 minutes for the stuff to be deliverd.About the quay walls,they are available in the landscaping menu,you must first build the wall,then you place the harbour or whatever you want to build.you cannot place the building first and then try to build the wall,DOES NOT WORK.

Not that much over production,got a city of like 220 k population,but a fair amount of exports with trains and cargo airport and 3 harbours with tracks to outside connections.The oil,farming and mining zones are allso like this forestry size.Took really al ot of thinking and planning the plasement of buildiungs to get it like i would say 80% working.

I did notice your pop and I imagine when it is scaled up to those numbers it will depend how much commercial / generic industry you have or exports from the unique factories (UF) etc to desire such production.

Building an industrial sector which contains all of the UF's does require some planning regarding the traffic. Having the shipping and rail connections that you do can only help. You have done well there.

How close are your UF's to your raw extractors and producers...?

For those with the Industries DLC I wonder how many will bother with Generic Industries specialised industry now...? Whilst it can still be used as yet I see little point in doing so over what this DLC has brought.

[iron721]

I am trying something new in my new city conserning UF buildings,going to try to put them all central to all the DLC industries surrounding them,so that the transport system moves into them and then out again from there,will see how it goes,lol

I'm still not making positive money yet, but it's gotten closer. I have all the industries built and will keep tweaking. I have not gotten to level 5 yet and seem to be stuck in 4. Any suggestions?

[Krik]

It shows in the bottom left what you need to upgrade to the next level. Levels depend on the amount of extracted/produced stuff and amount of workers.
I'm not sure but I think it was somewhere around 15.000 products and 1.500 workers for lvl 5.

If you click the industrial area (with the four stars) it will tell you what it's looking for. If you're short on workers as I was, you can plop more worker barracks - this seemed to increase the workers more than zoning residential nearby.

[Krik]

Zoning residential won't help. Only industry workers count. Workers in barracks count a industry workers.

I just started thinking... how many barracks do you need? They increase efficiency but also cost maintenance. When do both effects cancel each other out? Do they even cancel each other out?
If they don't you could just spam barracks and make more money than you'll ever need.

[iron721]

Yep you need barracks,get to 200% and build enough maintanence buildings,mine are all at 130%,looks like the storage units work better then,not sure but think so.

Unless there's a a couple of typos here, this first rule is not true... "trucks will only deliver not fetch", then... "warehouse will send their truck to resource extractor (or FA or export)".

This is fetch.

Also in first bullet, why would RE send to WH? WH is for finished goods not raw materials.

Should this say:

+ RE will send truck to RDP not WH
+ WH will send to RF not RE

????
This supply chain is seriously frustrating me, I have RDPs full of raw materials directly next to refineries that are not operating due to lack of raw materials, and 0 lorries operating. That's broken.

[MarkJohnson]

Your logic seems backwards.

Warehouses send (deliver) to factories. factories send (deliver) to warehouses.

Fetch would be:

Factory truck drives to warehouse and takes it back to factory, is wrong.

If a warehouse is sending a good to extractors, then it is importing, not exporting, so warehouse is (delivering) sending it to extractor.

If it is exporting, it is sending (delivering) from warehouse to outside connection.

If it is importing, it is sending (delivering) from outside connection to warehouse.

Just what I needed, awesome explanation :)
