Axiomatization Decision Log
1
Identity-Giving Function
Function class
PigReceivingFunction
⊑ DesignedFunction
Realized in
PigReceivingProcess
⊑ PlannedProcess
The identity-giving function is the capability to receive pipe pigs from a pipeline. This is distinct from general storage or containment functions because it specifically involves the controlled receipt and capture of cleaning/inspection devices traveling through pipelines.
2
Genus Determination
Vessel
All three definitions describe a pig receiver as a pressure vessel or chamber - a containment structure. The genus 'Vessel' is already enriched in the ontology with ContainmentFunction. While 'Receiver' appears in ISO 15926 hierarchy, it's not defined in our ontology, and 'Vessel' captures the essential containment nature while being more specific than Assembly.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
These parts are essential for the pig receiving function: a chamber to contain the pig, an entry port for pipeline connection, and pressure boundaries for safe operation.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PipelinePig
— traveling pig device with fluid carrier
Outputs (O)
PipelinePig
— stationary pig retained in chamber
PortionOfFluid
— carrier fluid potentially separated
Transformation (T)
kinetic energy removal from pig, spatial containment
The signature involves receiving a moving pig from the pipeline and transforming it to a captured/stationary state within the receiver chamber.
5
Axiom Mode Decision
Necessary + Sufficient
— modelled as a defined class
(≡, EquivalentClass). Automatic classification is
appropriate for this concept.
Disjointness Axioms
PigLauncher
C2: PigLauncher. Pig receivers and pig launchers have incompatible process signatures: receivers capture incoming pigs while launchers propel outgoing pigs into pipelines.
Cross-Standard Observations
All three standards consistently define pig receiver as a specialized pressure vessel/chamber for receiving pigs. CFIHOS emphasizes the pressure vessel aspect, POSC Caesar focuses on the chamber/pipeline connection, while ISO 15926 provides the most formal hierarchical placement.
