This section specifies the template risk_mitigation.

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 concept of risk mitigation in terms of PLCS model elements (templates, entities and reference data).

Business perspective

This information object represents the defintion of how a risk is mitigated.

Business object definition

This information object represents mitigation action required to reduce the probability and or the impact of a risk.

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_mitigation". The text highlighted in blue shows the template parameters.

Input parameters
The following input parameters are defined for this template:
ID (Type='STRING')
This is the identifier of the risk mitigation.
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
Impact_after_mitigation (Type='CLASS')
This is the impact of the risk after carrying out the mitigation activities that are defined in the related risk mitigation plan.
The following classes and their sub-classes can be used:
classifications: [High_risk_impact]
[warning:]Error RDL4: The URI urn:plcs:rdl:uk_defence is not listed in dexlib/data/refdata/rdl_index.xml
[Medium_risk_impact]
[warning:]Error RDL4: The URI urn:plcs:rdl:uk_defence is not listed in dexlib/data/refdata/rdl_index.xml
[Low_risk_impact]
[warning:]Error RDL4: The URI urn:plcs:rdl:uk_defence is not listed in dexlib/data/refdata/rdl_index.xml
Probability_after_mitigation (Type='NUMBER')
This is the probability of the risk event occurring after carrying out the mitigation tasks that are defined in the related risk mitigation plan.
Related_mitigation_plan (Type= 'ENTITY (Scheme)' )
This is the reference to the risk mitigation plan.
Related_risk (Type= 'ENTITY (
[warning:]Error ER1: The entity Risk does not exist
Risk)'
[warning:]Error EXP-1: The EXPRESS entity Risk
does not exist in data/schemas/ap239_arm_lf.xml.
)
This is the reference to the risk for which the mitigation is defined.
Reference parameters
The following reference parameters are defined for this template:
rsk_pcp(Type='ENTITY (
[warning:]Error ER1: The entity Risk_perception does not exist
Risk_perception)')
Allow the
[warning:]Error ER1: The entity Risk_perception does not exist
Risk_perception entity instantiated in this path to be referenced when this template is used.
Note: The
[warning:]Error ER1: The entity Risk_perception does not exist
Risk_perception entity can be referenced in a template path by:
%^target = $risk_mitigation.rsk_pcp%
where target is the parameter to which the
[warning:]Error ER1: The entity Risk_perception does not exist
Risk_perception is bound.

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

Instance diagrams
The instance diagram in Figure  4 shows an example of the EXPRESS entities and templates that are instantiated by the template:
/risk_mitigation(ID='mtg_001', ID_source_organization='UK_Defence', Impact_after_mitigation='Medium_risk_impact', Probability_after_mitigation='5', Related_mitigation_plan='#x', Related_risk='#r')/
(an illustration of the consolidated risk_mitigation 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:
/risk_mitigation(ID='mtg_001', ID_source_organization='UK_Defence', Impact_after_mitigation='Medium_risk_impact', Probability_after_mitigation='5', Related_mitigation_plan='#x', Related_risk='#r')/

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