Platform-Independent Debugging of Physical Interaction and Signal Flow Models

September 16, 2019
Author(s)
Mehdi Dadfarnia, Raphael Barbau
Systems engineering tools are used to organize development activities of a wide variety ofen gineers, many of which develop their own discipline-specific simulation models. To increase the efficiency of this process, systems modeling tools have been

Securing, Authenticating, and Visualizing Data-Links for Manufacturing Enterprises

August 26, 2019
Author(s)
William Z. Bernstein, Sylvere Krima, Laetitia Monnier, Mehdi Shahid
We introduce a prototype implementation of the Securing and Authenticating Data-Links (SADL) Interface, which interacts with a manufacturing handle registry to facilitate traceability of digital resources for engineering projects. This paper outlines the

SCAP Composer: A DITA Open Toolkit Plug-in for Packaging Security Content

August 9, 2019
Author(s)
Joshua Lubell
The Security Content Automation Protocol (SCAP) schema for source data stream collections standardizes the requirements for packaging Extensible Markup Language (XML) security content into bundles for easy deployment. SCAP bundles must be self-contained

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

Testing of the MTConnect - OPC-UA Companion Specification

June 14, 2019
Author(s)
Ryan Fisher, Guodong Shao
Smart Manufacturing (SM) is the future of the manufacturing industry. Seamless, accurate, and fast connection and communications among devices are critical for SM. By leveraging information technologies, devices can dynamically communicate with each other

Foundations of information governance for smart manufacturing

June 11, 2019
Author(s)
KC Morris, Yan Lu, Simon P. Frechette
The manufacturing systems of the future will be even more heavily dependent on the data than they are today. More and more data and information are being collected and communicated throughout product development lifecycles and across manufacturing value

Incorporating unit manufacturing process models into life cycle assessment workflows

May 5, 2019
Author(s)
William Z. Bernstein, Cesar D. Tamayo, David Lechevalier, Michael 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

Proceedings of the 9th Model-Based Enterprise Summit (MBE 2018)

May 1, 2019
Author(s)
Thomas D. Hedberg, Mark G. Carlisle
The ninth installment of the Model-Based Enterprise (MBE) Summit was hosted at the National Institute of Standards and Technology (NIST) on April 2-5, 2018. The MBE Summit 2018 witnessed another year-over-year registration growth. This speaks to the

2018 NIST/OAGi Workshop: Enabling Composable Service-Oriented Manufacturing Systems

April 22, 2019
Author(s)
Nenad Ivezic, Boonserm Kulvatunyou, Michael P. Brundage, Yan Lu, Evan K. Wallace, Albert W. Jones
This report summarizes the results from the 2018 NIST/OAGi Workshop: Enabling Composable Service-Oriented Manufacturing Systems, which was held at the National Institute of Standards and Technology campus in Gaithersburg, MD, on April 23-24, 2018. This was

Factory Optima: A Web-based System for Composition and Analysis of Manufacturing Service Networks based on a Reusable Model Repository

February 6, 2019
Author(s)
Alexander Brodsky, Mohan Krishnamoorthy, Mohomad O. Nachawati, William Z. Bernstein, Daniel A. Menasce
This paper reports on the development of Factory Optima, a web-based system that allows manufacturing process engineers to compose, optimize and perform trade-off analysis of manufacturing and contract service networks based on a reusable repository of

A New SCAP Information Model and Data Model for Content Authors

December 18, 2018
Author(s)
Joshua Lubell
The Security Content Automation Protocol (SCAP) data model for source data stream collections standardizes the packaging of security content into self-contained bundles for easy deployment. But no single data model can satisfy all requirements. The source

Standards-based integration of advanced process control and optimization

October 28, 2018
Author(s)
Guodong Shao, Hasan Latif, Carla Martin, Peter O. Denno
Integration of process control with optimization is critical to Smart Manufacturing (SM). Oftentimes, however, the process control solutions from one vendor do not interoperate with the optimization solutions of another. Incompatibilities among the

The Industrial Ontologies Foundry Proof-of-Concept Project

August 26, 2018
Author(s)
Boonserm Kulvatunyou, Evan K. Wallace, Dimitris Kiritsis, Barry Smith, Chris Will
The current industrial revolution is said to be driven by the digitization of manu-facturing that exploits connected information across all aspects of manufacturing. Standards have been recognized as an important enabler. Ontology is the next generation

System Lifecycle Handler -- Spinning a Digital Thread for Manufacturing

July 11, 2018
Author(s)
Manas Bajaj, Thomas D. Hedberg Jr.
Transforming the manufacturing economy from paper-based information flows to a seamless digital thread across geographically distributed supply chains has the potential to reduce cycle time by 75% and save manufacturers $30 billion annually. The "Digital
