SE DSIG Members,
The Systems Engineering Domain Special
Interest Group (SE DSIG) met at
the OMG Technical
Meeting in
from the meeting are
included below.
Joint Meeting with ADTF - SysML
Presentation
The SE DSIG held a joint meeting with the ADTF
to hear the Initial
Submission in response to
the UML for Systems Engineering (SE) RFP that was issued by the OMG on
Following the presentation, a procedural issue
was raised that the
submission did not
satisfy the OMG specification format. As a result,
a vote was passed
18-16 for SysML to be resubmitted at the next OMG
meeting. Despite this
setback, the feedback on the SysML technical
content and approach
was quite positive.
The SysML approach
reuses a subset of UML 2 and extends the language as required to satisfy the requirements of the UML for
* Activity
diagram extensions to support traditional SE funcitonal
flow block diagrams and continuous behaviors
* Composite
structure diagram extensions to better integrate input/output flows and
deployment
* A
new requirements diagram to model requirements, including provisions for
subtypes of requriements, traceability between
requirements, and assignment to model elements that realize the requirements.
* A
new parametric diagram that helps to model performance, reliability, and other
parametric relationships, and provide a bridge to engineering analysis tools
* Alignment
with AP-233 neutral data interchange format to support interchange of UML
models with other engineering tools, such as mechanical, electrical, and
analysis tools.
It is believed that these extensions of the
selected subset of UML 2
provides a
substantial systems modeling capability. Future versions
will be planned to
further enhance the language.
Feedback on SysML
Presentation to the ADTF
The SE DSIG held an afternoon session to
collect additional feedback
on the presentation.
Several inputs were received and will be provided
to the SysML team. A follow-up detailed review is scheduled for
January 25-26 at the INCOSE International
Workshop in
which is expected to
provide additional constructive feedback and
validation of the
approach.
AP-233/UML Integration Demonstration
Ian Bailey from Eurostep
presented a brief overview of the ISO STEP
Standards and AP-233.
AP-233 is the ISO STEP Standard that represents
a neutral data
interchange standard for systems engineering data to
support tool
interoperability. This development of UML for SE and the
AP-233 standard have been worked in a
cooperative effort from the
beginning to
establish both a systems modeling language and a neutral
data interchange
format that are compatible. AP-233 is
being
developed in a
modular fashion, and currently includes a module that
supports interchange
of text based requirements. Ian provided a brief
demonstration of how
a UML tool could exchange requirements
information with a
requirements management tool such as DOORS.
Additional information on AP-233 and
"STEP for UML Users" can be found

Collaboration with Other Activities
Several opportunities were noted for the SE
DSIG to interact with
other OMG
groups. Alan Moore reported on interest
in a UML profile
that could help drive
distributed simulations under the High Level
Architecture (HLA)
framework. Roger Burkhart
reported on interest
from the business
modeling activities of the Business Enterprise
Integration (BEI) task force,
and the potential synergy with the SE
DSIG, in such areas as
structural models and requirements management.
He also indicated some potential synergy with
current activities of
the Manafacturing and Industrial Systems (MANTIS), such as
product
structure and product
data management addressed by the Product
Lifecycle Management RFP,
and responses to the Knowledge-Based
Engineering RFI. Alan and Roger agreed to work on setting up
discussions on these
possible joint interests at the next OMG meeting
in
Next
The next
Technical Meeting in
2004.
