4 Information requirements

This clause specifies the information requirements for the Functional 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 Functional_breakdown_arm schema and identifies the necessary external references.

EXPRESS specification:

*)
SCHEMA Functional_breakdown_arm;
(*

4.1 Required AM ARM

The following EXPRESS interface statement specifies the elements imported from the ARM of another application module.

EXPRESS specification:

*)
USE FROM Product_breakdown_arm;    --  ISO/TS 10303-1248
(*

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

Product_breakdown_arm ISO/TS 10303-1248

NOTE 2   See Annex C, Figures C.1and C.2 for a graphical representation of this schema.

4.2 ARM entity definitions

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.

4.2.1 Functional_breakdown   EXPRESS-GMapping table

A Functional_breakdown is a type of Breakdown that identifies a partitioning of a product into a set of related functional elements so as to form explicit structural views that comprise the product elements.

The composite - component view is represented by Functional_element_usage instances relating the functional elements in the breakdown which are represented by Functional_elements.

EXAMPLE    A functional breakdown provides a decomposition of an aircraft in terms of high-level functional processes such as flight, taxiing and at rest all the way down to low-level processes such as detect onboard fuel level, move tail rudder and provide standard tow attachment point.

EXPRESS specification:

*)
ENTITY Functional_breakdown
  SUBTYPE OF (Breakdown);
END_ENTITY;
(*

4.2.2 Functional_breakdown_context   EXPRESS-GMapping table

A Functional_breakdown_context is a type of Breakdown_context that is an association of a Functional_element to a Functional_breakdown of which the functional element is a member.

EXAMPLE    A function 'provide load lifting capability' is member of the functional breakdown of a helicopter.

EXPRESS specification:

*)
ENTITY Functional_breakdown_context
  SUBTYPE OF (Breakdown_context);
  SELF\Breakdown_context.breakdown : Functional_breakdown_version;
  SELF\Breakdown_context.breakdown_element : Functional_element_definition;
END_ENTITY;
(*

Attribute definitions:

breakdown: the version of the Functional_breakdown of which the Functional_element is a member.

breakdown_element: the view of the version of the Functional_element that is a member of the Functional_breakdown.

4.2.3 Functional_breakdown_version   EXPRESS-GMapping table

A Functional_breakdown_version is a type of Breakdown_version that identifies a version of a Functional_breakdown .

EXPRESS specification:

*)
ENTITY Functional_breakdown_version
  SUBTYPE OF (Breakdown_version);
  SELF\Breakdown_version.of_product : Functional_breakdown;
END_ENTITY;
(*

Attribute definitions:

of_product: the Functional_breakdown_version shall only be a version of a Functional_breakdown .

4.2.4 Functional_element   EXPRESS-GMapping table

A Functional_element is a type of Breakdown_element that identifies the elements in one or more Functional_breakdown objects.

EXPRESS specification:

*)
ENTITY Functional_element
  SUBTYPE OF (Breakdown_element);
END_ENTITY;
(*

4.2.5 Functional_element_definition   EXPRESS-GMapping table

A Functional_element_definition is a type of Breakdown_element_definition that identifies a view of a version ( Functional_element_version ) of a Functional_element .

EXPRESS specification:

*)
ENTITY Functional_element_definition
  SUBTYPE OF (Breakdown_element_definition);
  SELF\Breakdown_element_definition.defined_version : Functional_element_version;
END_ENTITY;
(*

Attribute definitions:

defined_version: the Functional_element_definition shall only be a view of a Functional_element.

4.2.6 Functional_element_usage   EXPRESS-GMapping table

A Functional_element_usage is a type of Breakdown_element_usage that is an association of a functional element to another functional element that is a constituent. Functional_element.

EXPRESS specification:

*)
ENTITY Functional_element_usage
  SUBTYPE OF (Breakdown_element_usage);
  SELF\Breakdown_element_usage.parent_element : Functional_element_definition;
  SELF\Breakdown_element_usage.child_element : Functional_element_definition;
END_ENTITY;
(*

Attribute definitions:

parent_element: the parent functional element is constituted.

child_element: the functional element that is the constituent.

4.2.7 Functional_element_version   EXPRESS-GMapping table

A Functional_element_version is a type of Breakdown_element_version that identifies a version of a Functional_element .

EXPRESS specification:

*)
ENTITY Functional_element_version
  SUBTYPE OF (Breakdown_element_version);
  SELF\Breakdown_element_version.of_product : Functional_element;
END_ENTITY;
(*

Attribute definitions:

of_product: the Functional_element_version shall only be a version of a Functional_element .
