Den logistiske styring af ordreafgivelse og oplagring samt udlicitering af tilknyttede transaktioner, f.eks. maling af komponenter, der udføres på produktionslinjen, regnes ligeledes for et modul eller et undersystem.
Logistical supply and storage systems and subcontracted complete operations which form part of the production chain, such as the painting of sub-assemblies, should likewise be classified among these modules and sub-systems.
