Towards Operational Use of Unit Manufacturing Process Models

July 25, 2019
Author(s)
Amogh Kulkarni, William Z. Bernstein, David Lechevalier, Daniel Balasubramanian, Gabor Karsai, Peter O. Denno
Unit Manufacturing Processes (UMP) are models that capture succinct definitions of individual manufacturing steps in a manufacturing system. They are used to facilitate model composition and reuse. However, mainly due to their textual nature, they are

The Unit Manufacturing Process (UMP) Builder: User's Guide

July 3, 2019
Author(s)
David Lechevalier, William Z. Bernstein
The ASTM E3012-16 Standard Guide for Characterizing Environmental Aspects of Manufacturing Processes provides guidelines for formally characterizing manufacturing processes. However, the difficulty that has arisen in the early use of the standard

May 7, 2019
Author(s)
William Bernstein, David Lechevalier
This document presents supporting documentation for a reference implementation of the Unit Manufacturing Process (UMP) information model presented in ASTM E3012, Standard Guide for Characterizing Environmental Aspects of Manufacturing Processes. A version

Incorporating unit manufacturing process models into life cycle assessment workflows

May 6, 2019
Author(s)
William Z. Bernstein, Cesar D. Tamayo, David Lechevalier, Michael P. Brundage
Life cycle assessment (LCA) carries significant uncertainties and imprecision due to a number of factors, including the framework's linearity assumptions and the wide use of aggregate unit processes in practice. The goal of this work is to exploit the unit
