process parameter

IRI: https://spec.industrialontologies.org/ontology/construct/ProcessParameter

Defined In: https://spec.industrialontologies.org/ontology/biopharma/BiopharmaParameter/

SubClass Of: bfo:entity

Class Hierarchy

owl:Thing › bfo:entity › process parameter

Direct subclasses:

• critical process parameter
• key process parameter

Definition

process profile or temporal region or quality prescribed by a process parameter specification

Semi-Formal Definition:

every instance of ‘process parameter’ is defined as exactly an instance that is either a ‘temporal region’ or a ‘process profile’ or ‘quality’ and that is ‘prescribed by’ some ‘process parameter specification’

Explanatory Notes

See the expanded definition under the corresponding specification class. The term is formalized here as a defined class by referring to its corresponding specification class and exists primarily for ontological modeling and implementation convenience.

Examples

• agitation speed during the mixing process in a cell culture step; incubation time of the cell expansion process; temperature during the fermentation process; flow rate during the loading phase of a chromatography process; pH of the solution in the neutralization process; residence time in the viral inactivation process

Formal Axioms
