CPM: A Core Product Model for PLM support

Steven J. Fenves
Guest Researcher
Manufacturing Systems Integration Division,
National Institute of Standards and Technology
Gaithersburg, MD
(in collaboration with Sebti Foufou, Conrad Bock and Ram D. Sriram

Abstract: The support of PLM throughout the product life, from the product’s conceptualization to its disposal, requires reliable, complete and efficient data models. The Core Product Model (CPM), initially developed at NIST for a number of in-house research projects, has been extended so as to support the full range of PLM activities. CPM is an abstract model with generic semantics, defined as a UML class diagram. CPM gives equal status to three aspects of a product or artifact: its function, form and behavior. Thus, CPM can support purely functional reasoning about a product in the conceptual stages of design as well as the recording and modeling of its behavior in the post-design stage. Three levels of CPM models, denoted as the conceptual, intermediate, and implementation models, are described. Extensions of CPM are briefly presented.

About the speaker: Steven J. Fenves is University Professor Emeritus of Civil and Environmental Engineering at Carnegie Mellon University and is a Guest Researcher at NIST. He received his degrees in Civil Engineering from the University of Illinois and has taught at the University of Illinois, Carnegie Mellon, MIT, National University of Mexico, Cornell and Stanford. His research has dealt with computer-aided engineering, design standards, engineering databases, structural analysis, design environments and product models. He is the author of six books and over 300 articles and is a member of the National Academy of Engineering and an Honorary Member of the American Society of Civil Engineers.

Building Large Simulations using Physics-Based Models

Joseph B. Collins
Adv. Info. Tech.
Naval Research Laboratory
Washington, DC

Abstract: For the last several years Dr. Collins has been working with and developing DoD simulation Federates for representing the natural environment and its effects. The experience of integrating physics-based models within a large-scale simulation has led to a variety of questions. Some of these are: 1) How can we represent the semantics of the models that we use?  2) How can we know that two models may be meaningfully composed? 3) How can we discover a model, on the web or in a repository, that is suitable to our needs? Dr. Collins believes the answer to these questions lies in developing an Ontology of Physics, and he will present some ideas on what that might look like.

About the speaker: Joseph Collins, Ph.D., Physics Brown University, 1987. October 1988 to present - Research Physicist at Naval Research Laboratory (NRL), Washington D.C., in the Advanced Information Technology Branch.

Modeling System Structure and Dynamics with SysML Blocks

Roger Burkhart
Technology Architect
Product & Engineering Architecture
Deere & Company
Moline, IL

Abstract: This talk will describe how the block diagrams of the SysML modeling language can provide a standardized form of representation for both the structure of a system and equations that characterize its dynamics. SysML is an extension of the Unified Modeling Language (UML) for Systems Engineering, which is currently being finalized by the Object Management Group (OMG). The talk will also explore the potential use of SysML to facilitate communication across engineering disciplines and product development roles.

About the speaker: Roger Burkhart works on information technology architecture for engineering and other areas at John Deere in Moline, Illinois. His work emphasizes the use of computer-based models to enable collaboration across diverse business and technical concerns. Previously at Deere, he developed decision-support systems for factory design and production agriculture, simulation tools for multi-agent systems, and software frameworks for manufacturing planning.


Overview of Research at The Product & Systems Lifecycle Management Center

Chris Paredis
Assistant Professor
The George W. Woodruff School of Mechanical Engineering
Georgia Institute of Technology
Atlanta, GA

Diego R. Tamburini
Research Engineer - Lead Researcher
Product & Systems Lifecycle Management (PSLM) Center
Georgia Institute of Technology
Atlanta, GA

Abstract: This talk overviews the latest research being performed at the Georgia Tech Product & Systems Lifecycle Management Center. Dr. Tamburini will cover the center's research on Definition of Executable Design & Simulation Scenarios using SysML, and how we are merging our Composable Objects (COBs) techniques with SysML, to enable the development of collaborative, multi-disciplinary, multi-tool design and simulation environments. Dr. Paredis will cover Set-Based Design, an approach in which designers communicate with each other in terms of sets rather than point-solutions. Set-Based Design has been documented in the literature as being beneficial in terms of the quality of design solutions and the reduced need for iteration in the design process. Dr. Paredis will discuss the pros and cons of Set-Based Design in the broader context of decision theory. By providing a theoretical foundation for Set-Based Design, we identify potential improvements over current practice and directions for future research.

About the speakers:

Dr. Paredis is an Assistant Professor in the G.W. Woodruff School of Mechanical Engineering at Georgia Tech in Atlanta. He received a Ph.D. in Electrical and Computer Engineering from Carnegie Mellon University in 1996. He has a broad multidisciplinary background ranging from engineering design to information science and mechatronics. The focus of his current research is on information economics in simulation-based design: How should one manage modeling and simulation activities to obtain the best information at the lowest cost in support of a given design decision?

Dr. Tamburini is a Research Engineer in the Products and Systems Lifecycle Management (PSLM) Center and Manufacturing Research Center at the Georgia Institute of Technology. His research focus is in software infrastructures for integrated collaborative engineering, and the underlying knowledge representations and interoperability technologies to enable them. He is currently working on the design and development of the next-generation Composable Objects (COB) platform. Dr. Tamburini comes to Georgia Tech from the Microsoft Corporation, where he was the Technical Program Manager for the Engineering and Manufacturing Ecosystem, managing the technical relationship between Microsoft and the Independent Software Vendors in the CAD/CAE/PLM and Industrial Automation spaces. Prior to Microsoft, he worked at UGS (formerly SDRC) as a Principal PLM Implementation Engineer, helping large customers such as Boeing and Goodrich Aerospace implement UGS’ PLM system (known as Metaphase at the time). He received is PhD degree in Mechanical Engineering from Georgia Tech in 1999. His doctoral research was in design-analysis integration, where he developed the Analyzable Product Model (APM) representation, a new representation of engineering products aimed at facilitating design-analysis integration. This representation is based on constrained objects and object-oriented concepts - that defines formal, generic, computer-interpretable constructs to create and manipulate analysis-oriented views of engineering parts or products, leveraging engineering data exchange standards (such as ISO STEP). During this work, Dr. Tamburini developed some of the seminal techniques and algorithms currently used in Georgia Tech’s COB-based tools. Dr. Tamburini is a member of ASME and SME. He is a Co-Chair of the ASME CIE Engineering Information Management Technical Committee, and represents Georgia Tech at the SysML Merge Team, the Next-Generation Manufacturing Technology/Model-Based Enterprise Initiative, and PDES Inc.’s Mechatronics Interoperability Project for Systems.
