Logistic science pack

Logistic science pack is a research item used in the game's technology system. It is produced by assembling machines and requires several intermediate components such as inserters, transport belts, iron gear wheels, iron plates and electronic circuits. Production planning for Logistic science pack is commonly expressed as a set of assembler ratios and item-per-minute rates so a factory can be balanced and every assembler count is an integer.

The common reference calculation for production assumes Assembling machine 3 as the assembler, with no Modules or beacon effects, and that every assembler runs at full speed. Those reference tables are computed for the normal-difficulty recipe and intentionally omit some intermediate recipes when those components are assumed to be supplied in large quantities elsewhere in the factory. Typical intermediate items listed in the production breakdown include Inserter, Transport belt, Iron gear wheel, Iron plate and Electronic circuit; each of those has its own assembler requirements that feed into the Logistic science pack assemblers.

Practical notes for building a Logistic science pack production line:

• Use Assembling machine 3 for the main Logistic science pack assemblers when designing a high-throughput production line, because many published ratios and throughput tables are based on that machine without modules or beacons.
• Ensure steady upstream supplies of Electronic circuits, Iron gear wheels and Iron plates, and of subassemblies like Inserters and Transport belts if you produce them specifically for the packs; the reference tables assume those inputs are available at the rates shown.
• When copying or following ratio tables, remember they are calculated for normal recipe settings and full-speed assemblers; changing difficulty, adding productivity modules, or applying beacons will change required assembler counts and belt capacities.
• Omitted intermediate products in many ratio charts imply those parts are assumed to be produced elsewhere; explicitly include their production if you do not have a separate high-capacity source.
• If you alter machine tiers or add Modules or beacons, recalculate assembler counts and belt throughput rather than relying on raw numbers from tables that assume no modules and no beacon effects.

Logistic science pack production is most efficient when the entire supply chain is balanced from raw materials through gears and circuits to the final assemblers. Use the assembler-ratio references based on Assembling machine 3 as a starting point, then adapt them to your factory’s chosen recipe difficulty, module setup, and beacon layout.
