2. Abstract Standards-based Engineering Framework for Next Generation Product Lifecycle Management Manas 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 products and 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 this diversity 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 realizing this engineering framework for next generation PLM. We shall discuss and demonstrate the role of IDA-STEP in providing a framework 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 and Manufacturing Process models in a multi-user, distributed environment. In its current generation, IDA-STEP uses STEP-based content 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 for highly customizable and rich user interface. IDA-STEP supports models generated in many common ECAD, MCAD, Systems Engineering (SE), PDM, Manufacturing Process Planning (MPP) applications via STEP-based translators and interfaces available for them. In some cases, IDA-STEP has direct extensions available for these applications. The list of applications currently supported by IDA-STEP is as follows: MCAD - UGS-NX, CATIA, ProE, IDEAS Cabling – EPLAN, Logical Cable (prototype) ECAD - Mentor Boardstation, Zuken Visula, EAGLE, OrCAD PDM - UGS Teamcenter Engineering SE - UGS Teamcenter Requirements, DOORS, MS Project MPP– 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.
