AN INTEGRATED APPROACH TO INFORMATION MODELING FOR THE SUSTAINABLE DESIGN OF PRODUCTS

May 19, 2014
Author(s)
Paul W. Witherell, Douglas Eddy, Ian Grosse, Sundar Krishnamurty, Jack Wileden, Kemper Lewis
The design of more sustainable products can be best accomplished in a tradeoff-based design process that methodically handles conflicting objectives. Such conflicts are often seen between, environmental impact, cost, and product performance. To support

REQUIREMENTS ANALYSES TO SUPPORT A MATERIAL INFORMATION MODEL FOR SUSTAINABILITY

November 21, 2013
Author(s)
Paul W. Witherell, Arvind Harinder, Katherine C. Morris
Materials, and therefore material selections, influence the sustainable impact of a product from beginning to end-of-life. With improved access to material information, product designers can attain newfound insight into the sustainability implications of

TOWARDS THE SYNTHESIS OF PRODUCT KNOWLEDGE ACROSS THE LIFECYCLE

Author(s)
Anantha Narayanan Narayanan, Paul W. Witherell, Jae H. Lee, Katherine C. Morris, Sudarsan Rachuri
Materials play a central role in product manufacturing, contributing to each phase of product development in the form of either a component or process material. As the product revolves around materials, so does much of the product information. Material

FACTS: A Framework for Analysis, Comparison, and Test of Standards

May 9, 2013
Author(s)
Paul W. Witherell, Sudarsan Rachuri, Anantha Narayanan Narayanan, Jae H. Lee
Open and consensus standards play a critical role in enabling globally distributed manufacturing. A close connection between standards development (supply side) and implementation strategies (demand side) is critical for widespread adoption of standards

Sustainability through Lifecycle Synthesis of Material Information

April 19, 2013
Author(s)
Paul W. Witherell, Katherine C. Morris, Anantha Narayanan Narayanan, Jae H. Lee, Sudarsan Rachuri
The synthesis of material information across lifecycle stages will lay the foundation for a material information model to support sustainable decision making. This paper explores how material information is represented in select standards that address

Modeling Gaps and Overlaps of Sustainability Standards

May 28, 2012
Author(s)
Paul W. Witherell, Sudarsan Rachuri, Anna D'Alessio
Organizational and production dispersions in manufacturing enterprises can create situations where manufacturers are asked to conform to multiple sustainability standards to participate in targeted markets. These standards may vary in scope, application

Metamodels towards Improved Domain Modeling for Semantic Inferencing

October 3, 2011
Author(s)
Paul W. Witherell, Anantha Narayanan Narayanan, Jae H. Lee, Sudarsan Rachuri
As information requirements have increased, domain models have become increasing complex and difficult to manage. Though domain-specific languages have been developed for domain experts, increasing their expressivity and decreasing their complexity, their

In this paper, we identify five main obstacles in the development of an industry-ready application of semantic knowledge management systems and discuss how each of these challenges can be addressed. These obstacles include the ease of new knowledge

Towards a Methodology for Analyzing Sustainability Standards using the Zachman Framework

January 19, 2011
Author(s)
Sudarsan Rachuri, Prabir Sarkar, Anantha Narayanan Narayanan, Jae H. Lee, Paul Witherell
There exists a multitude of standards and regulations related to sustainability. It is critical to enable users to identify applicable standards across entire lifecycles of products, processes, and services. To synthesize this variety of standards, it is
