A Semantic Product Modeling Framework and Its Application for Behavior Evaluation

January 9, 2012
Author(s)
Jae H. Lee, Steven J. Fenves, Conrad E. Bock, Sudarsan Rachuri, Hyo-Won Suh, Xenia Fiorentini, Ram D. Sriram
Supporting different stakeholder viewpoints across the product’s entire lifecycle requires semantic richness to represent product related information and thus enable multi-view engineering simulations. This paper proposes a multi-level product modeling

Ram D. Sriram, Conrad E. Bock, Fabian M. Neuhaus, Evan K. Wallace, Mary C. Brady, Mark Musen, Joanne Luciano
The National Institute for Standards and Technology sponsored a workshop in October, 2007, on the subject of ontology evaluation. An international group of invited experts met for two days to discuss problems in measuring ontology quality. The workshop

Toward Energy Efficient Manufacturing Enterprises

February 2, 2011
Author(s)
Kevin W. Lyons, Alexander Weissman, Ram D. Sriram, Lalit Chordia
Industrial enterprises have significant negative impacts on the global environment. Collectively, from energy consumption to greenhouse gases to solid waste, they are the single largest contributor to a growing number of planet-threatening environmental

Modeling, Simulation and Analysis for Sustainable Product Development

November 17, 2010
Author(s)
Mahesh Mani, Bjoern J. Johansson, Kevin W. Lyons, Ram D. Sriram, Gaurav Ameta
Simulation plays a critical role in the design of products, materials and manufacturing processes. Increasingly, simulation is replacing physical tests to ensure product reliability and quality thereby facilitating steady reductions in design cycles

OntoSTEP: Enriching Product Model Data Using Ontologies

August 31, 2010
Author(s)
Raphael Barbau, Sylvere I. Krima, Xenia Fiorentini, Sudarsan Rachuri, Anantha Narayanan Narayanan, Sebti Foufou, Ram D. Sriram
The representation and management of product lifecycle information is critical to the success of any manufacturing organization. Different modeling languages are adopted to represent different product information, for example EXPRESS for geometry as seen
