SysML - Systems Modelling Language
The SysML Partners collaborated to define a modeling language for systems engineering applications, called Systems Modeling Language™ (SysML™). SysML customized UML 2.0 in order to support the specification, analysis, design, verification and validation of complex systems that include hardware and software components. The following are within the scope of SysML: Structure e.g., system hierarchies, interconnections Behavior e.g., function-based behaviors, state-based behaviors Properties e.g., parametric models, time variable attributes Requirements e.g., requirements hierarchies, traceability Verification e.g., test cases, verification results
17
Ap233 - Systems Engineering
ISO is an International Standard for the computer-interpretable representation of product information and for the exchange of product data. The objective is to provide a neutral mechanism capable of describing products throughout their life cycle. This mechanism is suitable not only for neutral file exchange, but also as a basis for implementing and sharing product databases, and as a basis for archiving. The following are within the scope of ISO/CD-TS : System behaviour System structure System modelling Decision support Requirements, analysis, trade studies Program and project management Verification and validation Risk management Issue management

Holy grail of exchanging & sharing data (1)
Seamless and total interoperability – Across disciplines, organizations, system levels, modeling methodologies, tools Flexible and precise formal open standards Reliable and affordable Affordable timely implementation and rigorously verified interfaces – Requires high quality public test suites with adequate coverage Future proof and stable for long term archiving – May include open source middleware 9th NASA-ESA Workshop on Product Data Exchange, Santa Barbara, CA, USA, 2-4 May 2007-
27
Holy grail of exchanging & sharing data (2)
Scalability from small messages to full design/analysis/test/operation datasets Pervasive and standardized configuration control / versioning Minimal loss of information and common denominator between different (classes of) tools Easy-to-use/easy-to-implement and spanning many disciplines Support for white-box and black-box (degenerated/encrypted) data -Coming from genuine business needs and IPR protection 9th NASA-ESA Workshop on Product Data Exchange, Santa Barbara, CA, USA, 2-4 May 2007-

"Classical" Engineering Data Standards and Ontologies
"Classical" engineering data exchange/sharing standards Scope is usually a relatively specific and confined end-user problem Terminology from software engineering (OO and/or ER) Explicit, often detailed formal data model or just a file format Reflection capabilities depend on implementation programming language Ontology's Scope is often a "grand" data sharing problem for a complete industrial/scientific sector Terminology shows scientific background, coming from philosophy, linguistics, artificial intelligence Simple core data model allowing to state a large number of 'facts' Built-in extensibility Allows automated reasoning (inferencing) and has built-in reflection 9th NASA-ESA Workshop on Product Data Exchange, Santa Barbara, CA, USA, 2-4 May 2007-

IBM: influencing and shaping open standards for PLM
1980s -1990s Java and ebXML ISO STEP OMG UML and XML OpenGL SQL AIAG IEEE VRML ANSI RosettaNet Web Services / Interoperability Eclipse to Open UDDI SOAP W3C XML SOAP4J to Open Open Systems OMG PLM Services STEP AP 214, 210, 219, 233, 239.. ProSTEP PDES Inc SASIG, AutoSAR, JAMA other industry groups IBM Enterprise Interoperability Center IBM Services Oriented Architecture BPEL WSBPEL WS-TX WS-TC OASIS For over 20 years, IBM has worked with our customers, industrial consortia, standards development organizations, technology services teams and our software partners, such as Dassault Systemes to develop and implement open CAD/CAM/PDM standards in our PLM product portfolio (CATIA, ENOVIA and SmartTeam). Over these years, IBM PLM has collaboratively influenced and shaped the industry, engineering and IT standards for PLM. IBM has had either leadership or key participation in over 30 standards related organizations and committees since the 1980‘s. On behalf of IBM‘s customers, partners and IBM as a manufacturer, IBM influences the direction and decisions of these organizations with the clear goal of developing standards to benefit the industry. IBM invests directly via membership fees, special projects, technology and has over 20 senior professionals who continue to play a significant role in many open, PLM related standards bodies. Recently IBM has been involved with defining 11 published standards and are colloborating on 7 other standards under development. These include: PLM Services 1.0 (published) Scope: PDM based on ISO STEP AP 214 Conformance Class 6 & 8. PLM Services 2.0 (under development) Scope: Engineering change management STEP AP 214 Conformance Class 1, 2, 6 & 8 (published) Scope: Geometry & PDM, implemented in CATIA, ENOVIA and by other ISVs. STEP AP 214 Conformance Class 21 (under development) Input from ProSTEP Engineering Change Management project STEP AP 203 E2 (published) Scope: Geometry & PDM, Implemented in CATIA, ENOVIA and by other ISVs. STEP AP 219 (under development) Scope: Dimensional Inspection, Impacts CATIA and DELMIA STEP AP 233 (under development) Scope: Systems Engineering, based on SysML & PDES Inc project. SysML (published) Provides input to ISO STEP AP 233 STEP AP 239 (published) Scope: Product Life Cycle Support, now under OASIS STEP Parts 108, 1050, 1051 (published) Scope: Dimensioning, Tolerancing, Parametrics & Constraints, Impacts CATIA and DELMIA PDF/A (published) Scope: PDF for archival, for 2D documentation PDF/E (under development) Scope: Adobe 3D, for 3D documentation 3D Presentation of product specification (published) Scope: 3D presentation of STEP data Long term data retention (LTDR, LOTAR) Scope: Long term data retention, product data archival STEP AP 209 (published) Scope: Analysis of metallic & composite structures. STEP AP 210 (published) Scope: Electronic assembly, interconnect & packaging STEP AP 212 (published) Scope: Electotechnical design and installation IBM has also invested in a european based interoperablity center and recently announced it‘s commitment to an open, services oriented architecture IBM plans to leverage this architecture to integrate the various disparate PLM tools, technologies and components to enable a collaborative product development and support ecosystem. IBM understands the need for standards. The market place doesn’t want to be locked up in proprietary systems; standards protect their investment. The market wants operate in heterogeneous environment and they need integration based on standards. Global supplier network, and mergers & acquisitions have made their environment even more heterogeneous. Standards avoid point-to-point, custom integrations that need continual maintenance and support. In the end, IBM understands that companies (IBM customers) drive open standards in PLM. IBM’s role and investment is as a participant in these standards consortia and IBM will continue to support these founded and managed bodies (e.g, PDES Inc, ProSTEP iViP, …).
