This section specifies the template risk_composition.

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 a risk composition.

Business perspective

A risk_composition represent the relationship between parent and child risks in a risk decomposition hierarchy.

Business object definition

This information object represent the relationship between parent and child risks in a risk decomposition hierarchy.

Figure 1 — A MOOD Business Architect representation of the Business Object: Risk composition

The attributes of the Risk composition object are tabled below.

Attribute name	Attribute description	Attribute type	Optionality
Child	This is the reference to the child risk in the decomposition hierarchy.	Risk	Mandatory
ID	This is the identifier of the risk composition.	Identifier	Mandatory
Parent	This is the reference to the parent risk in the decomposition hierarchy.	Risk	Mandatory

NOTE This template is dependent on entities in the ISO10303-239 Edition 2 schema.

Model diagrams

The EXPRESS-G diagram in Figure 2 shows the templates and EXPRESS entities that are required to represent the template "risk_composition". The text highlighted in blue shows the template parameters.

The graphic for the template to be used in other EXPRESS-G diagrams is shown in Figure 3 below.

Input parameters

The following input parameters are defined for this template:

Child (Type= 'ENTITY (

Error ER1: The entity Risk_perception does not exist
Risk_perception)'

Error EXP-1: The EXPRESS entity Risk_perception
does not exist in data/schemas/ap239_arm_lf.xml.
)

This is the "As Low As Reasonably Practicable" ALARP category of the risk.

ID (Type='STRING')

This is the identifier of the risk.

ID_source_organization (Default=UK_Defence,Type='STRING')

The organization that created the associated identifier. Additionally a Person or Information System could be defined when either of these are the source; see Identifier template characterizations

Parent (Type= 'ENTITY (

Error ER1: The entity Risk_perception does not exist
Risk_perception)'

Error EXP-1: The EXPRESS entity Risk_perception
does not exist in data/schemas/ap239_arm_lf.xml.
)

This is the impact of the risk before mitigation.

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.

/representing_view_definition_usage(
    related_product=@Child,
    relating_product=@Parent,
    class_name='Risk_composition',
    class_ecl_id='urn:plcs:rdl:uk_defence')/

-- ID
/identifier(
    ID=@ID,
    source_organization=@ID_source_organization,
    type='ID',
    items=$representing_view_definition_usage.view_usage)/

Instance diagrams

The instance diagram in Figure 4 shows an example of the EXPRESS entities and templates that are instantiated by the template:

/risk_composition(Child='#108', ID='5', ID_source_organization='UK_Defence', Parent='#1')/

(an illustration of the consolidated risk_composition template is shown in Figure 5 below.)

Figure 4 — Entities instantiated by risk_composition template

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:

/risk_composition(Child='#108', ID='5', ID_source_organization='UK_Defence', Parent='#1')/

Characterizations

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