A Core Product Model for PLM with an Illustrative XML Implementation

March 1, 2005
Author(s)
Sebti Foufou, Steven J. Fenves, Conrad Bock, Sudarsan Rachuri, Ram D. Sriram
We propose a Core Product Model (CPM) for modeling product information suitable for supporting the information needs of Product Lifecycle Management (PLM) systems over the lifecycle of the product from the earliest ideation to manufacturing, operation and

Information Models for Product Representation: Core and Assembly Models

March 1, 2005
Author(s)
Sudarsan Rachuri, Mehmet M. Baysal, Utpal Roy, Sebti Foufou, Conrad Bock, Steven J. Fenves, Eswaran Subrahmanian, Kevin W. Lyons, Ram D. Sriram
This paper presents a revised and unified view of the NIST Core Product Model (CPM) [1; 2] and the NIST Open Assembly Model (OAM) [3]. The CPM provides a base-level product model that is not tied to any vendor software; open; non-proprietary; simple

Ontology-based Exchange of Product Data Semantics

March 1, 2005
Author(s)
Lalit Patil, D Dutta, Ram D. Sriram
An increasing trend toward product development in a collaborative environment has resulted in the use of various software tools to enhance the product design. This requires a meaningful representation and exchange of product data semantics across different

Toward Data Standards for Proteomics Data

March 1, 2005
Author(s)
Veerasamy Ravichandran, Ram D. Sriram
Biologists have traditionally worked with relatively small data sets and shared results only with others working on similar biological systems. With the advent of genomics, and now proteomics, they are faced with exponentially growing sets of highly inter

CAD/CAPP Integration using Feature Ontology

January 1, 2005
Author(s)
C Dartigues, P Ghodous, Michael Gruninger, D Pallez, Ram D. Sriram
In a collaborative computer-supported engineering environment, the interoperation of various applications will need a representation that goes beyond the current geometry-based representation, which is inadequate for capturing semantic information. The

CPM 2: A Revised Core Product Model for Representing Design Information

January 1, 2005
Author(s)
Steven J. Fenves, Sebti Foufou, Conrad Bock, Roger Bouillon, Ram D. Sriram
This report presents a revised version of the Core Product Model (CPM) initially reported in [1]. The objectives of the report are: (1) to document the changes in the CPM relative to the first version; (2) to describe in detail the revised CPM, represented

Feature-Based Component Model for Design of Embedded Systems

November 1, 2004
Author(s)
XuanFang Zha, Ram D. Sriram
An embedded system is a hybrid of hardware and software, which combines software?s flexibility and hardware real-time performance. Embedded systems can be considered as assemblies of hardware and software components. An Open Embedded System Model (OESM) is
