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.

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.
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.

A
Functional_breakdown_context
is a type of
Breakdown_context
