This clause specifies the information requirements for the
Zonal breakdown
application module. The information requirements are specified as the
Application Reference Model (ARM) of this application module.
NOTE 1 A graphical representation of the information
requirements is given in
Annex C.
NOTE 2 The mapping specification is specified in
5.1. It shows how
the information requirements are met by using common resources and
constructs defined or imported in the MIM schema of this application
module.
The following EXPRESS specification begins the
Zonal_breakdown_arm
schema and identifies the necessary external references.
EXPRESS specification:

NOTE 1
The schemas referenced above are specified in the following
part of ISO 10303:

NOTE 2
See Annex C,

C.1and C.2
for a graphical representation of this schema.
This subclause specifies the ARM type
for this application module. The ARM type and
definition is specified below.
The in_zone_item type is an
extensible list of alternate data types
that allows for the designation of the data
type
Product_view_definition.
NOTE
The list of entity data types may be
extended in application modules that use the constructs of
this module.
Items that may be identified as being in a zone.
EXPRESS specification:
*)
TYPE
in_zone_item =
EXTENSIBLE
SELECT
(Product_view_definition);
END_TYPE;
(*
This subclause specifies the ARM entities for this
module. Each ARM application entity is an atomic element that
embodies a unique application concept and contains attributes
specifying the data elements of the entity. The ARM
entities and definitions are specified below.
An
In_zone
is a relationship between a
Zone_element
and an item that exists within the zone.
EXAMPLE
A pump is in the starboard engine room of a ship.
EXPRESS specification:
*)
ENTITY In_zone;
id : STRING;
name : STRING;
description :
OPTIONAL
STRING;
located_item : in_zone_item;
zone : Zone_element_definition;
END_ENTITY;
(*
Attribute definitions:
id:
an identifier for the relationship between the zone and the item in the zone.
name:
the words by which the In_zone is known.
description:
the text that provides further information about the relationship
between the zone and the item in the zone.
The value of this attribute need not be specified.
located_item:
the item that exists in the zone.
zone:
the region in which the item exists.
A Zone_breakdown is a type of
Breakdown
that identifies a partitioning of a product into a set of related zonal
elements so as to form explicit, parent-child views that comprise the
product elements.
The parent-child view is represented by
Zone_element_usage
instances relating the zonal elements in the breakdown which are represented by
Zone_elements.
EXAMPLE
A zonal breakdown provides a means of identifying the decomposition of an aircraft in terms of spaces or high-level
conceptual parts such as 'wing' - which might further decompose into lower-level zones
such as 'inner-wing', and 'outer wing'.
EXPRESS specification:
*)
ENTITY Zone_breakdown
SUBTYPE OF (Breakdown);
END_ENTITY;
(*
A
Zone_breakdown_context is a type of
Breakdown_context
that is a membership relationship between a
Zone_element
and a
Zone_breakdown
of which the zonal element is a member.
EXAMPLE
A 'fire-check zone' might be a member of the zonal breakdown of a building.
EXPRESS specification:
*)
ENTITY Zone_breakdown_context
SUBTYPE OF (Breakdown_context);
SELF\Breakdown_context.breakdown : Zone_breakdown_version;
SELF\Breakdown_context.breakdown_element : Zone_element_definition;
END_ENTITY;
(*
Attribute definitions:
breakdown:
the version of the
Zone_breakdown
of which the
Zone_element
is a member.
breakdown_element:
the view of the version of the
Zone_element
that is a member of the
Zone_breakdown.
A
Zone_breakdown_version
is a type of
Breakdown_version
that identifies a version of a
Zone_breakdown
.
EXAMPLE
An architect modifies the current fire-check zone breakdown for an building on the basis of reports from a
buildings inspector.
EXPRESS specification:
*)
ENTITY Zone_breakdown_version
SUBTYPE OF (Breakdown_version);
SELF\Breakdown_version.of_product : Zone_breakdown;
END_ENTITY;
(*
Attribute definitions:
of_product:
the Zone_breakdown_version shall only be a version of a
Zone_breakdown
.
A
Zone_element
is a type of
Breakdown_element
that identifies the elements in one or more
Zone_breakdown
objects.
EXAMPLE
'Empennage', 'Right vertical stabilizer and rudder' and 'Lower rudder' are all elements in a zonal breakdown
of an aircraft.
EXPRESS specification:
*)
ENTITY Zone_element
SUBTYPE OF (Breakdown_element);
END_ENTITY;
(*
A
Zone_element_definition
is a type of
Breakdown_element_definition
that identifies a view of a version
(Zone_element_version)
of a
Zone_element.
EXAMPLE
For an aircraft, an element 'Right vertical stabilizer tip' is in a zonal breakdown that an engineer uses for
reliability-centred maintenance analysis.
EXPRESS specification:
*)
ENTITY Zone_element_definition
SUBTYPE OF (Breakdown_element_definition);
SELF\Breakdown_element_definition.defined_version : Zone_element_version;
END_ENTITY;
(*
Attribute definitions:
defined_version:
the Zone_element_definition shall only be a view of a
Zone_element.
A
Zone_element_usage
is a type of
Breakdown_element_usage
that is a relationship between a parent and child
Zone_element.
EXAMPLE
In a zonal breakdown, the 'wing' (parent) might include (as children) an 'inner wing' and an 'outer wing'.
EXPRESS specification:
*)
ENTITY Zone_element_usage
SUBTYPE OF (Breakdown_element_usage);
SELF\Breakdown_element_usage.parent_element : Zone_element_definition;
SELF\Breakdown_element_usage.child_element : Zone_element_definition;
END_ENTITY;
(*
Attribute definitions:
parent_element:
the parent zonal element of the relationship.
child_element:
the child zonal element of the relationship.
A
Zone_element_version
is a type of
Breakdown_element_version
that identifies a version of a
Zone_element.
EXAMPLE
An engineer defines an inspection task on a breakdown element 'Upper rudder' that is part of a zonal breakdown
of an aircraft. The engineer identifies the corresponding view of the breakdown element.
EXPRESS specification:
*)
ENTITY Zone_element_version
SUBTYPE OF (Breakdown_element_version);
SELF\Breakdown_element_version.of_product : Zone_element;
END_ENTITY;
(*
Attribute definitions:
of_product:
the Zone_element_version shall only be a version of a
Zone_element
.
