Dynamic Production System Identification for Smart Manufacturing Systems

June 12, 2018
Author(s)
Peter O. Denno
Knowledge of process requirements, system capacities, and system reliability are the premises on which control policies are formulated. In dynamic manufacturing environments, engineering change to the product, the process, and the production equipment can

Self-Similar Architectures for Smart Manufacturing and Logistics Systems

February 5, 2018
Author(s)
Timothy A. Sprock
Self-similar architectures can simplify some design and interoperability challenges for smart manufacturing and logistics systems. To be effective, self-similar architectures for these domains must extend existing models of self-similar controller

Hybrid Datafication of Maintenance Logs from AI-Assisted Human Tags

January 15, 2018
Author(s)
Thurston B. Sexton, Michael P. Brundage, Michael L. Hoffman, Katherine C. Morris
One of the main challenges of applying AI to some datasets derives from the datasets themselves being unstructured, unclear, and ambiguous. Furthermore, the insights that are to be gained reflect the quality of the data itself; if the data is skewed, so

Manufacturing and Contract Service Networks: Composition, Optimization and Tradeoff Analysis based on a Reusable Repository of Performance Models

January 15, 2018
Author(s)
Alexander Brodsky, Mohan Krishnamoorthy, Mohomad O. Nachawati, William Z. Bernstein, Daniel A. Menasce
In this paper we report on the development of a software framework and system for composition, optimization and trade-off analysis of manufacturing and contract service networks based on a reusable repository of performance models. Performance models

Orientation Uncertainty Characteristics of Some Pose Measuring Systems

December 31, 2017
Author(s)
Marek Franaszek, Geraldine S. Cheok
We investigate the performance of pose measuring systems which determine an object's pose from measurement of a few fiducial markers attached to the object. Such systems use point-based, rigid body registration to get the orientation matrix. Uncertainty in

Research directions for an open unit manufacturing process repository: A collaborative vision

December 20, 2017
Author(s)
William Z. Bernstein, Arun Bala Subramaniyan, Alexander Brodsky, Ian C. Garretson, Karl Haapala, Donald E. Libes, Katherine C. Morris, Rong Pan, Vittaldas Prabhu, Arkopaul Sarkar, Arvind Shankar Raman, Zhenhua Wu
The design of manufacturing systems can see dramatic improvements through the use of digital technologies for modeling and simulation prior to deployment. At the 2017 ASME International Manufacturing Science and Engineering Conference held jointly with the

A Method for Key Performance Indicator Assessment in Manufacturing Organizations

December 12, 2017
Author(s)
Patrick Hester, Barry Ezell, Andrew Collins, John A. Horst, Kaleen Lawsure
Key Performance Indicators (KPIs) are an essential element of an organization's ability to monitor its strategic health, helping to ensure the strategic goals of the organization are achieved. However, KPI assessment and improvement is often an ad hoc and

Modeling the Internet of Things (& People): A Foundational Approach

November 16, 2017
Author(s)
Spencer J. Breiner, Eswaran Subrahmanian, Ram D. Sriram
This talk provides an overview of recent NIST work in the Internet of Things (IoT) domain in the Information Technology Laboratory. We begin with some examples and illustrations of the range of IoT systems. In addition to the obvious cyber physical aspects

Let’s truly add systems to industrial engineering

October 2, 2017
Author(s)
Timothy A. Sprock, Leon McGinnis
The ISE community can provide leadership in the design and decision-making required to support the scale, complexity and degree of automation expected of modern ISE systems, but only by adapting our legacy knowledge and tools to the required systems

Simulating a Virtual Machining Model in an Agent-Based Model for Advanced Analytics

September 25, 2017
Author(s)
David J. Lechevalier, Seungjun Shin, Sudarsan Rachuri, Sebti Foufou, Yung-Tsun T. Lee, Abdelaziz Bouras
Monitoring the performance of manufacturing equipment is critical to ensure the efficiency of manufacturing processes. Machine-monitoring data allows measuring manufacturing equipment efficiency. However, acquiring real and useful machine-monitoring data

Production System Identification with Genetic Programming

September 6, 2017
Author(s)
Peter O. Denno, Charles Dickerson, Jenny Harding
Modern system identification methodologies use artificial neural nets, integer linear programming, genetic algorithms, and swarm intelligence to discover system models. Paring genetic programming, a variation of genetic algorithms, with Petri nets seems to

Conceptual Modeling

August 19, 2017
Author(s)
Conrad E. Bock, Fatma Dandashi, Sanford Friedenthal, Natalie Harrison, Steven Jenkins, Leon McGinnis, Janos Sztipanovits, Adelinde Uhrmacher, Eric Weisel, Lin Zhang
Understanding and developing complex systems requires collaboration between individuals with widely varying expertise. Communication between these individuals is facilitated by conceptual models. Conceptual models are early stage artifacts that integrate

INVESTIGATING GREY-BOX MODELING FOR PREDICTIVE ANALYTICS IN SMART MANUFACTURING

August 8, 2017
Author(s)
Peter O. Denno, Yan Lu, Paul Witherell, Sundar Krishnamurty, Ian Grosse, Douglas Eddy
This paper develops a grey-box modeling approach that combines manufacturing knowledge-based (white-box) models with statistical (black-box) metamodels to improve model reusability and predictability. A white-box model can utilize different types of
