This section specifies the template WorkRequest.
The specification comprises a SysML Block that represents the template and an
associated Parametric Diagram that defines the templates and
PLCS PSM objects
instantiated by the WorkRequest template.
The specification comprises the following sections:
- Section Description provides a
description of the template;
- Section Template Block specifies the SysML
Block that represents the template;
- Section Template Properties specifies
the properties, i.e. the Part, Reference and Value properties of the
templates SysML Block;
- Section Template Output Ports
specifies the Output Ports of the templates SysML Block. These bind to the
templates and PLCS PSM objects
instantiated by the WorkRequest template as
described in section Template
Parametric Diagram;
- Section Template Constraints specifies
the constraints on PLCS PSM objects instantiated by the
WorkRequest template;
- Section Template Parametric
Diagram specifies the templates and PLCS PSM objects instantiated by the
WorkRequest template;
- Section Instantiated blocks specifies
the templates and PLCS PSM objects instantiated by the
WorkRequest template and bound to private
parts of the template;
- Section Default instances species the
instances that have been instantiated in the template. These are used to set
the default value of blocks.
- Section Constraint blocks identifies the
constraint blocks that have been specified in this template;
- Section Example data
provides example XML data sets that have been instantiated in accordance
with this template.
NOTE
An explanation of a template and its specification is provided in
the
Template
overview
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:
- representing request and authority for work,
- managed planned authorized activities and a corresponding record of the work done,
- unmanaged planned activities and a corresponding record of the activity done,
- record of activities performed by a product.
The actual templates are:
-
Managed work
- The WorkRequest template represents a
request for work to be undertaken;
- The WorkOrder template represents the
authorization of work to be undertaken, often in response to a WorkRequest;
- The DirectedActivity template represents
an activity that is planned to be undertaken under the authority of a given
WorkOrder.
- The WorkDone template represents a record
of the work done in response to an authorized DirectedActivity.
-
UnManaged activities
- The PlannedActivity template represents an
activity that is planned to be undertaken that is neither governed by a WorkOrder nor an activity to be performed by a
product.
- The ActualActivity template represents a
record of an activity that is performed in response to a PlannedActivity.
-
Product activities
- The ActualProductUsage template represents
a record of an activity that has been performed by a product, the
usage of a product.
Figure 1 - Templates representing activities
The SysML Block Definition diagram in Figure 2 shows how Work
order is represented in the PLCS PSM.
Figure 2 - Work request model
No templates have been explicitly defined as being related to the WorkRequest template.
NOTE
The WorkRequest template may make reference
to other templates as part of the Parametric Diagram. These are not listed
here.
Figure 3 shows the SysML Block that represents the template. The Block is an abstraction
representing a pattern of templates and PLCS PSM objects.
The properties, i.e. the SysML Block Part, Reference and Value properties, of the
template's SysML Block are described in the Template
Properties section.
The output ports shown on the template's SysML Block are described in the template output ports section.

The following output ports are defined for this template:
workRequest (Block: Ap239Ap233Psm:
WorkRequest)
Enables the
Block: Ap239Ap233Psm:
WorkRequest instantiated by this template to be referenced
when the template is used.
There are no constraints defined for this template.
This section describes the template's Parametric Diagrams. Each diagram details
the pattern of templates and PLCS PSM objects that are required to
represent the template WorkRequest.
The public properties, i.e. those visible in the template's SysML block (See Figure 3) are shown on the left of a
Parametric Diagram.
NOTE
Restrictions on the reference data to be set on the public properties is
defined in the
Template Properties section.
The output ports are shown on the right of the Parametric Diagram.
PLCS PSM
objects are shaded khaki and template shaded light green in a Parametric Diagram.
