Factorio Quality/Productivity Calculator

This is a simple calculator that simulates crafting with quality and productivity modules in Factorio. It is based on the idea of crafting items with quality and/or productivity modules, and the recycling items of lower quality using recyclers with quality modules. The simulation repeats this process until all simulated input ingredients are used up.

The term "ingredient" refers to the raw materials used to craft one single product. For example, an electronic circuit requires 1 iron plate and 3 copper cables as ingredients, so these are considered "1 ingredient" in the calculations.

Example

Inspired by Nilaus' "Crafting with Quality": Craft with 150% productivity and 31% quality, except for legendary products with 275% productivity and 0% quality. Recycle all normal, uncommon, and rare products with a quality of 24.8%.

qualictivity --normal-productivity 1.5 --normal-quality .31 --uncommon-productivity 1.5 --uncommon-quality .31 --rare-productivity 1.5 --rare-quality .31 --epic-productivity 1.5 --epic-quality .31 --legendary-productivity 2.75 --recycling-quality .248 --recycled-qualities normal uncommon rare

The simulation took 8 iterations.

Final products per 1000 ingredients:
epic: 71
legendary: 20

Total crafted products per 1000 ingredients:
normal: 1285 (55%)
uncommon: 737 (31%)
rare: 236 (10%)
epic: 71 (3%)
legendary: 20 (1%)

The total crafted products gives you an indication how to scale the production of each tier. In this example, about 55% of your factory buildings should build normal products, 31% should build uncommon products, and so on.
