Definition
work center within a broader production system that has specific tasks allocated to it
Examples
- a hydrochloric acid production unit, consisting of a combustion chamber where hydrogen and chlorine react, a cooling system to condense the HCl gas, and an absorption tower where the gas is dissolved in water to form hydrochloric acid; a styrene production unit via catalytic dehydrogenation of ethylbenzene, which includes preheating units, a catalytic reactor, and a separation train comprising a liquid-vapor separator and two distillation towers; a toluene hydrodealkylation production unit that converts toluene into benzene and methane by reacting it with hydrogen in the presence of a catalyst at high temperatures, comprising a furnace, chemical reactor, flash unit, separation columns, compressor, and multiple heat exchangers

Primitive Class
This class is declared primitive and it does not have necessary and sufficient condiftions defined.
Primitive Rationale
There are insufficient constructs to represent task allocation at this point.
