Author(s)
Shaw C. Feng, FNU Kumaraguru, Kincho H. Law, Kyeong Rim Ahn
This paper presents an on-going effort at NIST to model the energy performance in assembly and supply chain processes as a part of a larger sus-tainability improvement goal. Energy performance modeling comprises two dis-tinct metrics like energy

Status and Opportunities to Support Product Category Rules in the U.S.

August 12, 2013
Author(s)
Rita Schenck
Environmental Product Declarations (EPDs) are a kind of ecolabel that discloses the environmental impacts of a product over its life cycle, using the science of life cycle assessment. EPDs hold out the promise of supporting science based decisions in

A Model Based Continuous Improvement Methodology for Sustainable Manufacturing

August 7, 2013
Author(s)
Sanjay Jain, Guodong Shao, Alexander Brodsky, Frank H. Riddick
This paper proposes a model based continuous improvement methodology to support efforts to achieve sustainable manufacturing, i.e., to increase efficiency and reduce environmental impact of manufacturing systems. Past efforts have provided guidance at a

IDENTIFYING THE MATERIAL INFORMATION REQUIREMENTS FOR SUSTAINABLE DECISION MAKING

August 7, 2013
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

SUSTAINABILITY CHARACTERIZATION FOR DIE CASTING PROCESS

August 7, 2013
Author(s)
Megan F. Watkins, Mahesh Mani, Kevin W. Lyons, Satyandra K. Gupta
The manufacturing sector accounts for approximately one-third of the total energy consumption in the United States. Today, sustainable manufacturing has become an area of increasing interest, as companies look to reduce their manufacturing footprint and

CHARACTERIZING ENERGY CONSUMPTION OF THE INJECTION MOLDING PROCESS

June 14, 2013
Author(s)
Jatinder Madan, Mahesh Mani, Kevin W. Lyons
Presently available systems for sustainability assessment do not fully account for aspects related to a product’s manufacturing. In an effort to make more sustainable decisions, today’s industry seeks reliable methods to assess and compare sustainability

Disassembly Process Information Model for Remanufacturing

April 22, 2013
Author(s)
Shaw C. Feng, Hanmin Lee, Thomas R. Kramer, Che B. Joung, Parisa Ghodous, Ram D. Sriram
The disassembly process is an essential activity performed on out-of-service products for remanufacturing. A disassembly process includes many subprocesses, such as separation, cleaning, repair, replacement, and inspection. The main purpose of performing

Toward an Integrated Decision Support Framework for Sustainability CAE

April 22, 2013
Author(s)
Lalit Patil, Lakshmi Srinivas, Krishna Murthy, Debasish Dutta, Sudarsan Rachuri
Sustainability evaluation is typically conducted after the product is completely designed. However, sustainability, like cost and weight, needs to be managed on a continuous basis, throughout the product development cycle. This requires a decision support

Simulation and Analysis for Sustainable Product Development

January 9, 2013
Author(s)
Mahesh Mani
Purpose: Simulation plays a critical role in the design of products, materials and manufacturing processes. However, there are gaps in the simulation tools used by industry to provide reliable results from which effective decisions can be made about

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
