The ActualProductUsage template describes how to represent a record of the usage of
a product,
e.g. the use of an airplane
for a specific mission or the use of a truck for a specific transportation.
It represents an activity that has at least started and may have finished - an actual
activity.
It can be used to record any information about a product usage, such as what product
individual
was used, who has reported the product usage, what typical activity was followed,
and when
the product was used. It is
mandatory to assign an identifier or name to the activity, provide a start time if
the activity,
and identify the product being used.
The ActualProductUsage is one of a set of templates
used to represent 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.
The SysML Block Definition diagram in Figure 2 shows how a
activity is represented in the PLCS PSM.
The following Part, Reference, and Value properties are defined for this template:
References:
classifications [0..*] (Template: OASIS:
Classifier)
The classification of the activity.
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 the following class or a subclass:
location [0..*] (Block: Ap239Ap233Psm:
Location)
The location where the product was used.
plannedProductUsage [0..1] (Block: Ap239Ap233Psm:
Activity)
the planned product usage that resulted in this usage of the product being
undertaken.
Parts:
ids [1..*] (Template: OASIS:
Identification)
The collection of identifiers of the activity.
The reference data used in Template: OASIS:
Identification is restricted as follows:
RDL constraint 1:The id must be classified as an Activity_identification_code or a
subclass thereof.
The reference data for:
OASIS:Identification.role -> ExternalOwlClass.class
is restricted to the following class or a subclass:
status [0..1] (Template: OASIS:
StateAssertion)
the status of the activity
The reference data used in Template: OASIS:
StateAssertion is restricted as follows:
RDL constraint 1:The status is represented subclasses of State_of_activity.
The reference data for:
OASIS:StateAssertion.sameAs -> ExternalOwlObject.individual
is restricted to the following class or a subclass:
Example reference data is:
names [0..*] (Template: OASIS:
Name)
The names of the activity
