The Factorio calculator. Calculate quantities of machine and ingredient required in a factory to achieve materials production speed.

The powerful solver based on IPMs for LP allows factories with complex recipe chains and loops to be calculated without extra hassle.

Feature

• A recipe chain is configured to automatically calculate for each recipe.
• Supports recipe chains including loops, including quality recycling cascades and byproduct-heavy chains (e.g. Fulgora recycling).
• Folds modules, beacons, quality tiers, and force productivity research bonuses into the calculation.
• Calculate the total power used/generated and pollution emitted.
• Treats generators, boilers, mining, pumping, labs, fusion reactors, thrusters, agricultural towers and item spoilage as virtual recipes.
• Set limited machine and material constraints for calculations.
• Supports Factorio 2.0 / Space Age (quality tiers, fluid temperatures).

Warning: Multiplayer games have not been tested. Note that solution data may be lost if used.

How to use

1. Click the blue '+' button to create a new solution.
2. Choose the material to target for production speed.
3. Choose a recipe to product or ingredient that material.
4. Click on a material button in "Products" column or "Ingredients" column to add a recipe.
5. Click on a button in "Machine" column to set a machine, fuel and modules to be used.
6. Adjust the constraints to set the production speed to target.

The number in "Required" column is the quantity of machines required for each recipe. Use this as a guide to build your factory!

Note: Constraints can be added by right-click on material or recipe buttons.

Enabling quality modules

Qualities above normal start locked, so quality modules have no effect on the calculation until you unlock them in the solver:

1. Click the "Research bonuses" button to open its dialog.
2. Under "Unlocked qualities", check each quality you have researched.
3. Click confirm to apply.

The solver then expands recipes into the quality cascade, and quality modules shift production toward the higher tiers.

Why does the UI look like Factory Planner?

I originally developed the solver for linear problems as an additional feature of Factory Planner. However, that solver was not merged, so I decided to develop another mod from scratch specifically for that solver.
