AbstractStandards-based Engineering Framework for Next Generation Product LifecycleManagementManas Bajaj and Russell Peak (InterCAX and Georgia Tech), Lothar Klein (LKSoft and InterCAX), Mike Dickerson (InterCAX), Dirk Zwemer (InterCAX)

We envision a computer-based engineering framework that encapsulates tools, models and methods associated with productsand processes in the engineering world. A framework with this scope abounds with diversity of representation, techniques,interfaces and agents (humans and computers). Open standards (ISO STEP, W3C XML, OMG UML, etc.) enable to bridge thisdiversity with richer knowledge representation and semantic continuity.

In this presentation, we focus on current and emerging standards-based technologies that shall play a central role in realizingthis engineering framework for next generation PLM. We shall discuss and demonstrate the role of IDA-STEP in providing aframework for standards-based model and technique integration.

IDA-STEP (www.ida-step.net) is a standards-based PLM application that enables the integration of CAD, CAE, PDM andManufacturing Process models in a multi-user, distributed environment. In its current generation, IDA-STEP uses STEP-basedcontent models for product and process descriptions in the following domains: electronics (AP210), automotive (AP214),mechanical (AP203), cabling (AP212), systems engineering (AP233). Additionally, IDA-STEP uses XML-based technologies forhighly customizable and rich user interface.

IDA-STEP supports models generated in many common ECAD, MCAD, Systems Engineering (SE), PDM, ManufacturingProcess Planning (MPP) applications via STEP-based translators and interfaces available for them. In some cases, IDA-STEPhas direct extensions available for these applications.

The list of applications currently supported by IDA-STEP is as follows:MCAD - UGS-NX, CATIA, ProE, IDEASCabling – EPLAN, Logical Cable (prototype) ECAD - Mentor Boardstation, Zuken Visula, EAGLE, OrCADPDM - UGS Teamcenter Engineering SE - UGS Teamcenter Requirements, DOORS, MS ProjectMPP– eMPlanner

We shall also highlight some key CAE-based applications that use the standards-based product models created / enriched by IDA-STEP for high fidelity analyses.

Conclusion

Challenges in engineering frameworks (EFW) for next-generation PLM

Philosophy for knowledge management in PLM EFW

IDA-STEP – encapsulates our philosophy for knowledge management

Simulation-based Design – the need for rich product models



Knowledge representations of physical objects (including information models)

– Includes math-based models of physical behavior

– Adds their semantic contexts

Also learn information modeling and other richer knowledge representation techniques

Needed Shifts in Engineering Thinking

Math-based models of physical behavior

Learn mathematics as a modeling language

Note: Information models have their roots in modern mathematics (e.g. set theory).

Information/KnowledgeRepresentation Viewpoint

Rich Features in AP210: Electrical Component

The 3D shape is generated from these “smart features” which have electrical functional knowledge. Thus, the AP210-based model is much richer than a typical 3D MCAD package model.

210 can also support the detailed design of a package itself (its insides, including electrical functions and physical behaviors).
