Towards a Virtual Factory Prototype

December 5, 2015
Author(s)
Sanjay Jain, David Lechevalier, Jungyub Woo, Seungjun Shin
A virtual factory should represent most of the features and operations of the corresponding real factory. Some of the key features of the virtual factory include the ability to assess performance at multiple resolutions and generate analytics data similar

Performance Challenges Identification Method for Smart Manufacturing Systems

November 27, 2015
Author(s)
Kiwook Jung, Katherine C. Morris, Kevin W. Lyons, Swee K. Leong, Hyunbo Cho
Smart Manufacturing Systems (SMS) need to be agile to adapt to new situations by using detailed, precise, and appropriate data for intelligent decision-making. The intricacy of the relationship of strategic goals to operational performance across the many

Using Semantic Web Technologies to Integrate Models to Analytical Tools

November 9, 2015
Author(s)
Peter O. Denno, Mark R. Blackburn
This paper discusses the potential advantages and pitfalls of using semantic web technologies in the process of preparing engineering analyses. Analytical tools are often not designed to be integrated with disparate information sources and general-purpose

Analysis and Optimization in Smart Manufacturing based on a Reusable Knowledge Base for Process Performance Models

November 1, 2015
Author(s)
Alexander Brodsky, Guodong Shao, Mohan Krishnamoorthy, Anantha Narayanan Narayanan, Daniel Menasce?, Ronay Ak
In this paper, we propose an architectural design and software framework for fast development of descriptive, predictive, diagnostic, and prescriptive analytics solutions for dynamic production processes. The proposed architecture and framework are based

A "Smart Component" Data Model in PLM

October 28, 2015
Author(s)
Yunpeng Li, Utpal Roy, Seungjun Shin, Yung-Tsun Lee
Today's physical products are becoming smarter not only because of their increasingly complex functionalities, but also for their superior capabilities of adaptation to dynamic working environment based on embedded software and real-time information

Intelligence Level Performance Standards Research for Autonomous Vehicles

October 1, 2015
Author(s)
Roger V. Bostelman, Tsai H. Hong, Elena R. Messina
U.S. and European safety standards have evolved to protect workers near Automated Guided Vehicles (AGV's). However, only recently performance standards have begun development for AGV's and mobile robots. Lessons can be learned for developing such a

Exploring Model-Based Engineering Concepts for Additive Manufacturing

September 15, 2015
Author(s)
Robert R. Lipman, Jeremy S. McFarlane
Robust geometry and tolerance representations are needed in additive manufacturing for precise part specification and interoperability with downstream activities such as manufacturing, inspection, and long-term archiving. A disconnection exists between

DESIGN RULES WITH MODULARITY FOR ADDITIVE MANUFACTURING

September 11, 2015
Author(s)
Haeseong J. Jee, Yan Lu, Paul Witherell
Design rules in additive manufacturing (AM) can help ensure manufacturability, which can be viewed as compatibility between designs and the fabrication processes that produce those designs. Additionally, such rules frequently provide direct guidelines or

Standards Landscape and Directions for Smart Manufacturing Systems

August 24, 2015
Author(s)
Yan Lu, Katherine C. Morris, Simon P. Frechette
The future of manufacturing lies in being able to adapt quickly to changing conditions. From smaller lot sizes, to more customization, to sudden changes in supply chain, the variability that manufacturers face is rapidly increasing. The key to enabling

Software Tools for XML to OWL Translation

July 7, 2015
Author(s)
Thomas Kramer, Benjamin H. Marks, Craig I. Schlenoff, Stephen B. Balakirsky, Zeid Kootbally, Anthony Pietromartire
This paper describes a set of closely related C++ software tools for manipulating XML (eXtensible Markup Language) schemas and XML instance files and translating them into OWL (Web Ontology Language) class _les and OWL instance files. They include: (1) an

Strategy for extensible, evolving terminology for the Materials Genome Initiative efforts

July 1, 2015
Author(s)
Talapady N. Bhat, Ursula R. Kattner, Laura Bartolo, Carelyn E. Campbell, John T. Elliott
Intuitive, flexible, and evolving terminology plays a significant role in capitalizing on recommended knowledge representation models for material engineering applications. In this article we present a proposed rules-based approach with initial examples

Preface: Special Issue on Knowledge Driven Robotics and Manufacturing

June 30, 2015
Author(s)
Craig I. Schlenoff, Stephen B. Balakirsky, Edson Prestes
State-of-the-art robots are capable of sub-millimeter movement accuracy. However, they are often programmed by an operator using crude positional controls from a teach pendent. Reprogramming these robots when their task is altered requires that the robot

Fundamental Requirements for Data Representations in Laser-based Powder Bed Fusion

June 8, 2015
Author(s)
Shaw C. Feng, Paul W. Witherell, Gaurav Ameta, Duck B. Kim
Additive Manufacturing (AM) processes intertwine aspects of many different engineering-related disciplines, such as powder material metrology, design, in-situ and off-line measurements, control. Due to the increasing complexity of AM systems and processes
