Production science pack

The Production science pack is a mid-game science pack whose production ratios and raw resource requirements are documented for factory planning. Ratio tables for producing Production science pack are calculated assuming Assembling machine 3 running at full speed with no Modules or beacon support, and they present the minimum assembler/machine counts and item throughput such that all assembler counts are whole numbers. Several intermediate products are omitted from those ratio tables under the assumption that they are available in large quantities within the factory. The published ratio tables use the normal-difficulty recipe set.

Raw resource accounting for a single Production science pack (excluding productivity bonuses) lists the total raw inputs required when Advanced oil processing is used and when all oil products are cracked down into petroleum gas. The raw resources counted are Iron plate, Copper plate, Coal, Crude oil, Water, and Stone. These raw-cost summaries are intended to show the base resource demands for scaling production, not the full intermediate crafting chains.

Practical notes for planning and production:

• The published assembler ratios assume Assembling machine 3; using lower-tier assemblers will reduce per-machine throughput and require more assemblers to meet the same science output.
• All assembler ratios assume no Modules and no beacon effects; adding Modules or beacons changes the required counts and throughput calculations and can improve factory footprint and resource efficiency.
• Some intermediate recipes and producers are omitted from the ratio tables; include crafting steps for advanced circuits, steel plate, stone brick, rails, or other intermediates when laying out full production lines if those items are not already supplied in bulk.
• The raw-cost list assumes Advanced oil processing and complete cracking to petroleum gas; if those technologies or cracking steps are not used, adjust crude oil and petroleum-derived inputs accordingly.
• Ratio tables and raw-cost summaries are calculated on a per-minute basis to aid throughput planning; convert to per-second or per-hour as needed for belts, inserters, and logistic throughput design.

The available documentation focuses on factory-level planning metrics (assemblers and item throughput) rather than explicit step-by-step crafting instructions. Use the ratio tables as a baseline factory blueprint and adapt assembler counts and resource deliveries to match Module, beacon, and technology choices made in your specific game.
