Axiomatization Decision Log
1
Identity-Giving Function
Function class
PigLaunchingFunction
⊑ DesignedFunction
Realized in
PigLaunchingProcess
⊑ PlannedProcess
The identity-giving function is the capability to launch (send/insert) pipeline pigs into a pipeline system. This is a specialized function distinct from general containment or piping functions, involving controlled insertion of cleaning/inspection devices into pressurized pipelines.
2
Genus Determination
Vessel
All definitions describe pig launchers as pressure vessels or chambers - specialized containment equipment. 'Vessel' is the most specific appropriate superclass that captures the pressure containment aspect while being more specific than generic 'Assembly'. The parent candidates don't include a more specific launcher category, and 'Vessel' is already enriched in our ontology.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
These parts are necessary for the basic pig launching operation - connection to pipeline, chamber for pig containment, and valve for controlled release.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PipelinePig
— solid cleaning/inspection device
PortionOfFluid
— pressurized driving fluid
Outputs (O)
PipelinePig
— inserted into pipeline
PortionOfFluid
— propelling fluid into pipeline
Transformation (T)
mechanical insertion and propulsion of pig into pipeline system
The signature captures the essential operation: receiving a pig and driving fluid, then inserting the pig into the pipeline with propelling fluid pressure.
5
Axiom Mode Decision
Necessary + Sufficient
— modelled as a defined class
(≡, EquivalentClass). Automatic classification is
appropriate for this concept.
Disjointness Axioms
PigReceiver
C2: PigReceiver. Pig launchers send pigs into pipelines while pig receivers collect pigs from pipelines - opposite directional operations with incompatible process signatures.
Cross-Standard Observations
All three standards converge on the pressure vessel/chamber concept with pipeline connection capability. ISO 15926 emphasizes the launching function, while CFIHOS and POSC Caesar focus on the pressure vessel aspect. The definitions are complementary and consistent.
