Description

This mod can be installed mid-game.
All features can be enabled/disabled anytime and only affect player.
This is a semi-auto builder for assisting player to build efficiently. For better private constructions, I recommend using Controllable Private Construction.

Updates

20.08.2025

New feature: auto-build construction sectors.

Feature Summary

Expand the selected supply chains systematically and in the most profitable way while also taking both economy of scale and balanced development into account.
Auto-build more construction sectors if the budget allows.
Auto-build new railways and power plants in suitable states gradually.
One-click plan a new local supply chain (build new buildings) in a suitable state.
Calculate the suitable construction number to avoid too short/long construction queue, so that it can react to market change faster and allows player to better manage the construction queue.

Expand Existing Buildings Of Selected Supply Chains

Semi-Auto Builder (SAB) can expand the existing buildings of the selected supply chains efficiently. This can be enabled for different supply chains separately.
It will calculate a country's Suitable Construction Number (SCN) based on construction output, government funded allocation and max weekly progress. SAB will adjust how many constructions will be added to the construction queue each time according to SCN and the current construction number, so that too short/long constructions queue can be avoided and SAB can react to market change faster.
It will find out all suitable buildings that meets certain conditions, then order them by Weighted Profitability (WP). WP is determined by:
WP = Profit/Building Level * State Construction Efficiency - 1000 * Construction Status
Each suitable building gets a Weighted Profitability Rank (WPR) after the ordering.
WPR = 1 means this building is the most suitable building.
WPR = 2 means this building is the second most suitable building, and so on.
SAB will then select suitable buildings to expand based on WPR and SCN. This process will try to take both EoS and balanced development into account.
Multiple levels of the same building can be added to the queue at once. The added levels of a building are based on WP, WPR, SCN, infrastructure, etc. (image 10).
Production buildings are divided into different supply chains by SAB, e.g., chemicals supply chain includes buildings that produce iron, sulfur, wood, dye, paper, fertilizer and explosives.
The building types of a supply chain might change as technology develops.

Auto-Build Construction Sectors

Auto-build more construction sectors when the budget and investment pool income allow.
States that are populated, have higher construction efficiency and suitable resources will be prioritized.

Auto-Plan New Railways And Power Plants

SAB will plan and build new railways and power plants automatically and gradually in states that meet certain conditions but don't have them yet.
It will find out all suitable states and order them by certain criteria, then start the constructions in the most suitable states.
New railways and power plants can be built again every 6 months.

Expand Railways And Power Plants

SAB can expand railways and power plants that meet certain conditions efficiently.
The expanding will try to keep the local price of transportation/electricity close to but slightly higher than their base prices, or try to eliminate all infrastructure deficit and provide some surplus.
If no maximum expanded levels were set, the required added levels for a railway or a power plant each time will always be added to the construction queue at once.
The added levels will be calculated based on local production, consumption, infrastructure and current levels, which means it doesn't rely on PMs and the result will still be accurate even if the output number of railway and power plants are modified by mods.

One-Click Plan New Local Supply Chains

One-click plan a new local supply chain in a suitable state. SAB will try to build the most essential buildings of the supply chain that the state hasn't have yet.
The more populated a state is and more suitable resources it has, the more priority will be given to it.
If "Flexible Resource Limit" is enabled, suitable resource types aren't mandatory requirements but only increase the priority.
Optional: exclude states that have more than three factory types.
Optional: a new supply chain won't be planned if more than 30% of states already have this supply chain.
Support four types of important and fundamental supply chains: machines, chemicals, glass and china, electrics.

Incorporated States Only

If this option is selected, SAB will only build and expand buildings in incorporated states.

How to use

Only works on vanilla building types.

Localization

@acemaker This mod usually doesn't need to update with different game versions (unless Paradox decided to rework some supply chains), but I will have a look when I have time.

Are there any breaking changes with 1.10? Also, if you need help with this mod, I'd be glad to contribute.

@장변 Yes, you can integrate this mod to your own mods, as long as there are credit and a link back to here.

장변 31 Aug @ 11:31pm

Hello!
I'm Jang Byeon, and I'm broadcasting on YouTube!
I’m writing to ask if it would be alright to include this mod in a multiplayer mod pack during my broadcasts.
If you could kindly give your permission, please leave a comment or send me an email at buddybuddy@kakao.com, or message me on Steam. I’d be happy to discuss further!
Wishing you a wonderful day!

不是很清楚你说的”自动建设“是什么，因为原版游戏中并没有这个概念，只有“自动扩建”和“私人建设”

关于如何使用本mod，描述里说得很清楚：
1. 订阅本mod。
2. 使用决议“产业链管理”激活日志条目。

关于具体功能，我建议先阅读日志中按钮的描述或者mod描述。

这个是优化自动建设吗？不开自动建设这个mod不会起作用（测试了一下开自动建设后开本mod与不开mod的新建是差不多的除了铁路和发电厂）实在不懂这个mod是什么作用希望作者解答一下

@Zardes @MK80993 @shiningstar2k There is no easy way to check a state's used trade capacity right now, I tried calculating them one by one in the script but I found it not worthy for performance.
