Definition
object aggregate that is a physical, geographical, or logical grouping of one or more work centers or work units within a physical site
Explanatory Notes
The boundaries (scope) of the site is typically determined by business/organizational criteria and not technical criteria Within the manufacturing domain, area typically serves as a way to organize manufacturing operations (ISA95 operation) within a site
Examples
- dock area of an oil terminal; fuselage assembly area of an aircraft factory; ground testing area of a facility that performs maintenance, repair, and overhaul services on an aircraft line; liquid effluent treatment plant that is part of an antibiotic manufacturing facility; utilities area of an oral liquids manufacturing plant
Adapted From
- ISA95 and ISA88 Part 1
Primitive Class
This class is declared primitive and it does not have necessary and sufficient condiftions defined.
Primitive Rationale
This term is expected to remain primitive as the exact grouping criteria are ogranization specific
Formal Axioms
First-Order Logic Axioms
PhysicalArea(x) → ObjectAggregate(x) ∧ ∀y(hasMemberPartAtSomeTime(x,y) → (WorkCenter(y) ∨ WorkUnit(y))) ∧ ∃z(PhysicalSite(z) ∧ memberPartOfAtAllTimes(x,z))
Semi-Formal Natural Language Axioms
if x is a ‘physical area’, then x is an ‘object aggregate’, every entity that x ‘has member part at some time’ is a ‘work center’ or ‘work unit’, and x is ‘member part of at all times’ some ‘physical site’
