Template:— platform_system_equipment_behaviour (pse_bhvr)
Context:— UK_Defence
Date: 2009/04/17 10:48:48
Revision: 1.6

This section specifies the template platform_system_equipment_behaviour.

NOTE  The template has been defined in the context of UK_Defence. Refer to the business context for details of related templates.

NOTE  An explanation of a template and the associated instantiation path is provided in the Template overview section.

Description

This template describes how to represent the collection of information that defines the predicted behaviour of the platform, system and equipment constituents that are referenced by the related FMECA object, which in turn are defined in terms of: - The anticipated failures, failure modes, their expected probabilities, frequencies of occurrence and effects. - The consequences of expected failures and failure modes

Input parameters
The following input parameters are defined for this template:
related_pse (Type= 'ENTITY (Product_group)' )
This is the reference to the platform, system and equipment for which the related FMECA's have been conducted.
defined_by (Type= 'ENTITY (Document)' )
This is the reference to the set of FMECA that defines the PSE behaviour.
id (Type='STRING')
This is the identifier of the PSE behaviour.
source_organization (Type='STRING')
An Organization representing the identification/rectification authority for the behaviour.
name (Type='STRING')
This is the name of the PSE behaviour.
version (Type='STRING')
The version (identifier) of the PSE behaviour.
Reference parameters
The following reference parameters are defined for this template:
pse_behaviour(Type='ENTITY (Document_assignment)')
Allow the Document_assignment entity instantiated in this path to be referenced when this template is used.
Note: The Document_assignment entity can be referenced in a template path by:
%^target = $platform_system_equipment_behaviour.pse_behaviour%
where target is the parameter to which the Document_assignment is bound.
The collection of information that defines the predicted behaviour of the platform, system and equipment constituents that are referenced by the related FMECA object.
Instantiation path
The instantiation path shown below specifies the entities that are to be instantiated by the template.
A description of templates and the syntax for the instantiation path is provided in the Templates Help/Information section.
-- Create failure_type_consequence
%^pse_behaviour = Document_assignment%

-- id identifier
/identifier(
    ID=@id,
    source_organization=@source_organization,
    type='pse_behaviour_id',
    items=^pse_behaviour)/

-- name identifier
/identifier(
    ID=@name,
    source_organization=@source_organization,
    type='name',
    items=^pse_behaviour)/

-- version identifier
/identifier(
    ID=@version,
    source_organization=@source_organization,
    type='version',
    items=^pse_behaviour)/

-- The consequential relationship between the failure type during usage and the consequence.
^pse_behaviour.is_assigned_to -> @related_pse
^pse_behaviour.assigned_document -> @defined_by
Instance diagrams
The instance diagram in Figure  4 shows an example of the EXPRESS entities and templates that are instantiated by the template:
/platform_system_equipment_behaviour(defined_by='#2', id='pse_behaviour_1', source_organization='6421', name='pse_name', related_pse='#98', version='1')/
(an illustration of the consolidated platform_system_equipment_behaviour template is shown in Figure 5 below.)

The instance diagram in Figure 5 shows the graphic symbol for the template that is to be used in other instance diagrams. The example template is:
/platform_system_equipment_behaviour(defined_by='#2', id='pse_behaviour_1', source_organization='6421', name='pse_name', related_pse='#98', version='1')/

Characterizations
No common characterizations of the template platform_system_equipment_behaviour have been identified. However, the ISO 10303-239 EXPRESS model may enable other assignments to the entities instantiated by the template.
