Logistics issue I can't solve

[Vonlutt]

I understand that the logistics system is very complex. I've watched several videos, and I think/thought I had the hang of it, but unfortunately I've run into one that I can't seem to tackle.

My current issue is in regards to getting supply in and out to my SHQ and then back out to the units. I went into a world war and none of my units were getting replacements and that's when I started a deep dive on what was going on and began upgrading my logistics to the max everywhere I could.

So here is what I have:

Zone > SHQ 261435/592103 (this was as high as 970,000 but has stabilized around the 600k mark but wont go lower.)
Replacement >0/2105)

The other requirements are being met and the logistical points usage is not maxed out in any category, but my zone supplies aren't getting consolidated, replacements aren't going out, and I have bottlenecks. I have a Rail VII on my SHQ/capital, Truck VII, and three HS Rail Station VII's on the rail lines into the capital directly adjacent to the capital hex itself. The only thought I can think of is maybe the Rail VII and truck VIIs cant accommodate the load from the HS rails next to it? I'm really not sure...

Thank you

Erm, why did you change your default settings to 10% ? That means only 10% of max value will be used for this - but since those values are green this is not right now the problem.

In Zone >SHQ you have only half requirement fullfilled (sending resources from other cities back to SHQ). Check what LoS value you have on those black lines. Maybe try steering rail points back to SHQ rather than evenly distributing it in all rail network (with traffic signs).

How big is your empire? If you only have one SHQ in a rly big empire all zones sent their ressources back to your capital and if they need sth the capital will sent it back to the zone. so the roads near your capital will be used mulitple times for transport every ressource from far away districts to the cap and back. even more the bigger you get. So maybe more trucks near the capital. Or a second SHQ? Thats a huge amount of ressources pilled out there in the zones. So it will take a few rounds to send them all back to the capital.
Are you using traffic sings?

[Vonlutt]

I lowered them to see if lowering the allocation for the others, who's need are all being met, would somehow spur the problem to fix itself, which it had no effect on. I understand that the requirements are not being met I'm just confused on why, if having more than enough logistics points and not maxing them out, they aren't transporting to their max and bottlenecks are still there. Even on my farthest reaches the units have 715 logistics points but they are not getting reinforced.

How do I steer them back exactly, should I do a custom pull or would it be just limiting traffic out vs incoming? I mean if the logistical network isn't even using all the points I'm confused as to why its not pulling.

@ Flight Captain

It's a very large empire, and I'm only using 1 SHQ. I thought upgrading to all HS rails like this everywhere would solve the issue, and making so many around my capital but it hasn't had an effect which is confusing.

I'm really just trying to identify and solve exactly what the problem is so I can avoid it in later games and its driving me crazy.

[Flightcaptain]

https://www.youtube.com/watch?v=YguinWE9KCo&t=1s have a look here maybe this could help.
How many logistic points do you have available in the current state / those fore usage of strategic movement? If the bottlenecks have zero that means that no traffic could go through there. even if there are points present near your units.

[Thomas]

You have more than enough points in your whole empire maybe - but in that one place - you have bottleneck - not enough points to move all resources along those two rail lines.

[Flightcaptain]

so first try using more traffic sings relocating more points from the green lines to the black lines?

[Vonlutt]

Yeah I have way more than enough points as seen in the screen shots, so trying to figure out what exactly would fix it. Should I have a dedicated rail line that doesn't intersect any of the other cities' lines? Line up truck station VIIs all around the capital? Just trying to identify what's causing the shortage when the numbers say there shouldn't be one.

[Vonlutt]

Another odd problem that's certainly tied into it, I have 3 units on top of the SHQ, and the SHQ has its replacements, that aren't getting replenished. Just doesn't want to send out any replenishments anywhere.

Look up logistic refocusing on the manual, you are losing a massive amount of output from your capital logistical assets because of it. Other than that you need to shape your logistics with traffic signs and even then it will take time to fix as there is a massive backlog of stuff to transport from your other zones to the SHQ.

For a quick fix go to your SHQ logistics panel and set the max % used to 30/20/30/20

The only thing the manual says about refocusing is :

5.11.1.6. Refocusing of Logistical Points
Once your Logistical Points spreading out from a Logistical Asset reach
another active Logistical Asset in a different Hex they’ll be Refocused.
Refocusing means that they’ll start at their original full distance potential
again but lose part of their Logistical Points equivalent to the percentage of
its distance potential already used.
With the first Refocusing a further penalty of -25% onLogistical Points is
applied. With the second Refocusing a penalty of -50% is applied and with
the third Refocusing

I understand that I am losing points and need to focus it, but my whole lines are maintaining around 90% everywhere. It's just right at the capital where I have a nasty bottleneck that won't resolve and limiting the flow out doesn't seem to be having an impact or pulling more into the capital either. Destroying the Rail VII and making a HS rail now...

Edit: I also have traffic signs reducing pull on unused routes and making sure excess isn't being pushed to farms and factories.

[George The Ork]

So your logistic lines can be carried on a 'pony express' but lose 25% of their potential range each time they do so?

So proper train ports should make rails viable for a whole planet, right? Unless the supplies get so handicapped that you end up with 0 range truck stations at the exit point?

[Svechin]

Wouldn't the supply base be pointless then if it causes refocusing? Same with a railhead. It seems from the way that is written building supply bases or railheads actually damages your logistics.

Further I have kept a lean road structure and it doesn't work once your empire reaches a certain size. I found that building loads of truck stops may be a inefficient solution but if the efficient method doesnt work brute forcing it seems to.

Could someone who actually knows the maths of it perhaps show an example of say a level VI city with SHQ with a "correct" logistical layout to a decent sized empire of 30 cities? Can you show how you would build it to have 0 logisitical problems and bottleknecks?

A case study would really really help!

[Saros]

Supply bases and railheads dont refocus but truck and rail stations do. What is happening here is probably about 1/3 or more of the logistics points generated around the capital are being lost to refocusing because of all the rail/truck stations in adjacent hexes.

Also use traffic signs on you capital hex to send more LP down the bottlenecked line.
