Template:- OASIS:WorkRequest

The WorkRequest template describes how to represent a request for some work to be undertaken.

The WorkRequest is one of a set of templates used to represent work and activities. These are summarized in Figure 1 which shows that the model contains templates for:

The actual templates are:

The SysML Block Definition diagram in Figure 2 shows how Work order is represented in the PLCS PSM.

Template Properties

The following SysML Part, Reference, and Value properties are defined for this template:

References:
requestor [0..1] (Block: Ap239Ap233Psm:OrganizationOrPersonInOrganizationSelect)
the person or organization that raised the WorkRequest
status [0..1] (Block: Ap239Ap233Psm:ProxyItemSelect)
the status of the WorkRequest.
The reference data used in Block: Ap239Ap233Psm:ProxyItemSelect is restricted as follows:
RDL constraint 1:
The status is represented subclasses of State_of_work_request.
The reference data for:
OASIS:StateAssertion.sameAs -> ExternalOwlObject.individual
is restricted to the following class or a subclass:
assignedTo [0..*] (Block: Ap239Ap233Psm:OrganizationOrPersonInOrganizationSelect)
the person or organization that the WorkRequest has been assigned to for resolution
triggeredBy [0..*] (Block: Ap239Ap233Psm:JustificationSupportAssignmentSelect)
the reasons that lead to the WorkRequest being raised
appliesTo [0..*] (Block: Ap239Ap233Psm:WorkRequestAssignmentSelect)
the subject of the WorkRequest.
Parts:
ids [1..*] (Template: OASIS:Identification)
The identifiers assigned to the WorkRequest.
The reference data used in Template: OASIS:Identification is restricted as follows:
RDL constraint 1:
The ids must be classified as an Work_request_identification_code or a subclass thereof.
The reference data for:
OASIS:Identification.role -> ExternalOwlClass.class
is restricted to the following class or a subclass:
description [0..*] (Template: OASIS:Descriptor)
An optional description assigned to the WorkRequest.
An optional description assigned to the WorkRequest
version [0..1] (Template: OASIS:Identification)
the version identifier being assigned to the WorkRequest.
The reference data used in Template: OASIS:Identification is restricted as follows:
RDL constraint 1:
The identifier must be a version identifier.
The reference data for:
OASIS:Identification.role -> ExternalOwlClass.class
is restricted to the following class or a subclass:
classifications [0..*] (Template: OASIS:Classifier)
The classification of the WorkRequest.
The reference data used in Template: OASIS:Classifier is restricted as follows:
RDL constraint 1:
The reference data for:
OASIS:Classifier.class -> ExternalOwlClass.class
is restricted to classes that are subclasses of the following class:
name [0..*] (Template: OASIS:Name)
An optional name assigned to the WorkRequest.
Values:
dateRequested [0..1] (Block: Ap239Ap233Psm:DateTimeString)

The following constraint, normally a uniqueness constraint, is applicable when instantiating the DateTimeString:

rule.Ap239Ap233Psm.ExternalOwlClass.ur1
Constraint: XSDDATETIME
Specification: (OCL2.0)
self.matches('[0-9]{4}-[0-9]{2}-[0-9]{2}T[0-9]{2}:[0-9]{2}:[0-9]{2}Z')
