Subject: SE DSIG Meeting in St Louis - April
27-28, 2004
- Summary
SE
DSIG Members,
The following is a brief
summary of our SE DSIG meetings at the OMG meeting in St Louis on April 27-28. This email and the
reference document will be available on the SE DSIG site at http://syseng.omg.org.
Sandy and Roger presented
the current status of SysML in response to the UML
for SE RFP issued in March 2003. The
presentation (syseng/2004-04-02) will be available on the SE DSIG site and
includes a summary of the SysML requirements and
design approach and the primary SysML extensions to
UML 2. The SysML specification is still an
early draft with the revised submission to be submitted to the OMG on August
2, 2004. A
follow-up review is scheduled with INCOSE/AP-233 members on May
25, 2004 in
Pasadena, California.
The SE DSIG met jointly with the Manufacturing and
Industrial Systems (MANTIS) DTF from 1430 to 1500 on Tuesday,
April 27, 2004. This meeting was a followup to a joint
meeting held at the previous meeting at Anaheim in which areas of joint interest to
both groups had been identified. Roger Burkhart provided a recap of these
areas, which include the relation of OMG activities to those of STEP (ISO
10303), and CAD Services and Knowledge-Based Engineering activities on the
MANTIS roadmap. The PLM Services specification just recommended for
adoption by the MANTIS TF relies on mappings between UML and EXPRESS according
to STEP Part 25 that will also be of interest in mapping UML for Systems
Engineering to its related STEP modules. These are being developed as part
of the AP233 group within STEP. AP233 also makes heavy use of Product
Data Management modules which have been translated to UML as part of PLM
Services. Jim U'Ren of NASA JPL, chair of AP233
and also active in the UML for SE work, continues to coordinate the relation of
the UML for SE activity to STEP. A discussion of the CAD Services
specification clarified its potential role in providing an interface to
attributes about geometric models managed by a CAD system. An overview of
a draft RFP for Knowledge-Based Engineering (KBE) by Russ Claus indicated a
potential for alignment with multiple Systems Engineering interests including
design rules and parametric relationships and their use to drive optimization
and tradeoff analysis.
The SE DSIG met jointly with
the Business Enterprise Integration DTF (BEI DTF) from 9:00-12:00 on Wednesday,
April 28, 2004. Before beginning the joint meeting discussions, Fred Cummins of
the BEI DTF reviewed a revised draft of an Organization Structure Metamodel (OSM) RFP to be issued by the BEI DTF. The
potential for reuse of common concepts of organization structure and roles
between human organizations and engineered systems was noted during this
discussion. Roger Burkhart then provided a recap of the discussion
between the two groups that had begun at Anaheim, in which multiple areas of
potential joint interest between the two groups had been identified.
These included the potential for common concepts of organization and structure,
the differences between process models for collaboration vs. execution,
vocabularies for requirements and business rules, and the range of requirement
types for business or engineering systems. On the BEI DTF roadmap,
submitter teams are merging their proposals for process models as part of the
Business Process Definition Metamodel (BPDM) and
their results may provide a basis to explore the relation of collaborative
process models to models of structure and flow needed for systems
engineering. The Business Semantics of Business Rules (BSBR) RFP is also
going through revised submissions which may provide a basis for defining
vocabularies in which rules are stated, which could apply to the statement of
requirements in systems engineering. The BEI DTF held a discussion
earlier in the week regarding strategic planning from the Business Rules Forum
(based on a paper at www.businessrulesgroup.org/second_paper/BRF-BRMM.pdf). The relation of business
strategic planning and models of motivation and goals in business to the
statement of requirements in engineered systems was discussed with a suggestion
to look at this related material.
