Industry Trouble

[Creon]

Im having some issues keeping my petroleum refinery operation 100% of the time. It keeps stopping production because its lacking the special goods. What I don't understand is why the special goods are being taken directly from the special goods production facilities that are across the town instead of from the full wharehouse yard that is directly next to the petroleum refinery. Here is an image to help understand what Im talking about.

The Petroleum Refiner is in blue
The wharehouse yard that is full of special goods is in red
The special goods processing facility is in green

If your warehouse is set to balance and getting full it will search for demand to get in balance ( 50-60%) again . If , in the moment of search , there is no demand from your unique factories or any other generic industry , it will export . Build another warehouse of that kind . If your unique factory needs specialized products it creates demand for that type and is delivered from whoever can do it in that moment the demand is created . You need more storage of that type

I just dont understand why the uniqie factory would request materials from a factory across the map and not from the full capacity wharehouse that is directly next to the unique factory.

tenho esse problema também.

When you click on the full warehouse how many freight trucks does it say it’s using? If the warehouse is using all its trucks to export than there will not be any trucks left to do local deliveries. The way the supply chain is configured in CS is that the processor/unique factory orders the resources from a warehouse or raw material storage area and the warehouse/storage area delivers the requested materials. If the warehouse or storage area are using all their freight trucks to export than they’ll have no vehicles to make the deliveries. Building more warehouses is a short term fix because eventually that warehouse will also fill up and the pattern begin again. It almost sounds like you’re not consuming enough of what you’re producing locally causing the warehouses to look elsewhere for customers. Building more warehouses while slowly cutting back on production will force your unique factories to use what’s on hand in the warehouses and you won’t have such a drastic amount of excess taking up storage space.

My wharehouses have products in them, its using 0/13 trucks, and yet my unique factories are still getting their product from across the map

Wow, are you using any traffic mods like TMPE, make any policy changes like enacting a heavy traffic ban, or make any changes like making a road one way? This is a new one for me, never heard of it happening before.

I am using traffic manager president, and no I do not have any traffic policies in my city, nor do I have any one way roads near my industry.

A building producing materials checks for exporting materials once it gets 8 tons in it's storage. It first checks if there are consumers that need the material at that exact moment, then for storage buildings that can take it, then for exporting the materials. Storage can fill up if trucks can not return to the building quickly enough and this most often happens when exporting materials to another city. Mass transit exports can help with this but are not always used. It is possible to force mass transit to be used by cutting off road access and forcing exports to go through a mass transit station. This will shorten the distance that your trucks must travel, allowing them to return quicker and ship more, but will hide the zone's profit.

A building consuming materials checks for importing materials once it gets 8 tons free in it's storage and again if it gets to 16 tons free. Since the base storage is eight more than what is consumed in two weeks, if shipments can consistently arrive in less than 2 weeks a building can continuously produce. This travel time buffer can be increased for processors with maintenance buildings that increase storage capacity. For unique factories it can be increased to as much as 4 weeks by decreasing production rate. There is no way to increase a unique factories storage. The game does not always request materials from the closest source so to keep things flowing consistently the furthest possible source of consumed materials needs to be within that travel time.

In my understanding it is working like service - citywide .

I´m with you
But he needs more storage to catch his overproduction right now and more trucks for delivery too . In long term he could change them to what is needed

I just tried repeating this situation in one of my newer cities that’s still balancing supply and demand and found that this is an easy situation to get yourself into but at the same time can be difficult so I agree with you. The first step the OP needs to make is increase the number of available freight vehicles and expand warehouse capacity to catch their overproduction so they can slowly release it to market (exports) over time until the situation is resolved.

What the OP needs to do is troubleshoot himself, the petro factory requires 3 products, which one or more is he missing out on? We dont know as he hasnt said. He should then check back down the line and work out why that product isnt getting to the factory.

Does the warehouse storing that product have any spare trucks to do local deliveries? Is he relying on the, (for example only) petrol to come straight from the waste oil refining plant? Which would be a big mistake on its own.

Remember that in CS, no ind or com building whatsoever makes pick ups, all items are delivered only, there are no pickups. So the petro factory will not send out a vehicle to pick up the required product, it will wait till that product is delivered.
