Flow Control in Time-Varying, Random Supply Chains

January 22, 2013
Author(s)
Ion Matei
Today�s supply chains are more and more complex. They depend on a network of independent, yet interconnected moving parts. They rely on critical infrastructures and experience a lot of time variability and randomness. Designing strategies that deal with

STEP File Analyzer User's Guide

December 13, 2012
Author(s)
Robert R. Lipman
This guide describes how to use the STEP File Analyzer that generates a spreadsheet from a STEP file. The spreadsheet simplifies inspecting information in the STEP file at an entity and attributes level. Geometric, PMI, assembly, annotation, attribute, and

Toward Better Integration of Vehicle Assembly Production Systems

November 15, 2012
Author(s)
Jorge Arinez, John L. Michaloski, Frederick M. Proctor, William G. Rippey, C J. Yen
In today's manufacturing world, system integration often necessitates composing systems of technology that are not designed to interoperate with each other. This inherent incompatibility results in redundant, non-value added work that is required for

A VIRTUAL MACHINE TOOL FOR THE EVALUATION OF STANDARDIZED 5-AXIS PERFORMANCE TESTS

October 26, 2012
Author(s)
Ronnie R. Fesperman Jr., Shawn P. Moylan, M A. Donmez
Standards committees are actively working to develop standard test methods for the performance evaluation of 5-axis machining centers through the direct and indirect measurement of simultaneous motions of all five axes [1-2]. However, the compound effect

SysML extension for dynamical system simulation tools

October 26, 2012
Author(s)
Ion Matei, Conrad E. Bock
Computer-interpretable representations of system structure and behavior are at the center of designing today’s complex systems. Engineers create and review such representations using graphical modeling languages that support specification, analysis, design

An IEEE Standard Ontology for Robotics and Automation

October 12, 2012
Author(s)
Craig I. Schlenoff, Edson Prestes, Rajmohan Madhavan, Paulo Goncalvest, Howard Li, Stephen B. Balakirsky, Thomas R. Kramer, Emilio Miguelanez
In this article, we discuss a newly formed IEEE- RAS working group entitled Ontologies for Robotics and Automation (ORA). The goal of this working group is to develop a standard ontology and associated methodology for knowledge representation and reasoning

An Industrial Robotic Knowledge Representation for Kit Building Applications

October 12, 2012
Author(s)
Stephen B. Balakirsky, Zeid Kootbally, Craig I. Schlenoff, Thomas R. Kramer, Satyandra K. Gupta
The IEEE RAS Ontologies for Robotics and Automation Working Group is dedicated to developing a methodology for knowledge representation and reasoning in robotics and automation. As part of this working group, the Industrial Robots sub-group is tasked with

An Approach to Ontology-Based Intention Recognition Using State Representations

October 7, 2012
Author(s)
Craig I. Schlenoff, Sebti Foufou, Stephen B. Balakirsky
In this paper, we present initial thoughts on an approach to ontology/logic-based intention recognition based on the recognition, representation, and ordering of states. This is different than traditional approaches to intention recognition, which use

Web-enabled Real-time Quality Feedback for Factory Systems using MTConnect

August 15, 2012
Author(s)
John L. Michaloski, Byeong Eon Lee, Frederick M. Proctor, Sid Venkatesh
Quality is a key element to success for any manufacturer, and the fundamental prerequisite for quality is measurement. In the discrete parts industry, quality is attained through inspection of parts but typically there is a long latency between machining

Model Based Enterprise / Technical Data Package Summit Report

August 13, 2012
Author(s)
Joshua Lubell, Kenway K. Chen, John A. Horst, Simon P. Frechette, Paul J. Huang
This report summarizes the presentations, discussions and recommendations of a workshop held at the National Institute of Standards and Technology in December of 2011. The purpose of the workshop was to identify challenges, research, and implementation

Testing Phasor Measurement Units using the IEEE 1588 Precision Time Protocol

July 1, 2012
Author(s)
Julien M. Amelot, Gerard N. Stenbakken
As the electric power grid is changing to a smarter more dynamically controlled system, there is increasing need for measurements that show the global status of the system for wide-area monitoring and control. These measurements require time

Next Generation Packaging, Kitting, and Palletizing: Can one robot do it all?

June 28, 2012
Author(s)
Rajmohan (. Madhavan, Stephen B. Balakirsky, Craig I. Schlenoff
A seminar titled "Next Generation Packaging, Kitting, and Palletizing: Can one robot do it all?" was held on February 9th 2012 at the Material Handling Industry of America (MHIA) MODEX show in Atlanta, GA. The seminar primarily focused on whether systems

Detection of Cutting Phenomena Using Sensor Fusion

June 8, 2012
Author(s)
John A. Slotwinski, Gregory W. Vogl, Robert W. Ivester, Ian Younker
This paper presents an investigation of the application of a suite of sensors for simultaneous in-situ measurements of machining processes. While not every individual sensor responds to all machining phenomena, the suite of sensors together responds to

Using Competitions to Advance the Development of Standard Test Methods for Response Robots

May 17, 2012
Author(s)
Adam S. Jacoff, Raymond Sheh, Ann Virts, Tetsuya Kimura, Johannes Pellenz, Soren Schwertfeger, Jackrit Suthakorn
Competitions are an effective aid to the development and dissemination of standard test methods, especially in rapidly developing, highly varied fields such as Urban Search and Rescue robotics. By exposing the development process to highly developmental

Web-enabled, Real-time, Quality Assurance for Machining Production Systems

April 19, 2012
Author(s)
John L. Michaloski
In order to maintain the close control of production quality, frequent measurement and process parameter adjustments are desirable. In the discrete parts industry, part inspection is intended to be a metric for the process quality but quality control is

Performance Evaluation of Robotic Knowledge Representation (PERK)

March 22, 2012
Author(s)
Craig I. Schlenoff, Sebti Foufou, Stephen B. Balakirsky
In this paper, we explore some ways in which symbolic knowledge representations have been evaluated in the past and provide some thoughts on what should be considered when applying and evaluating these types of knowledge representations for real-time

An Analysis of Solver-Based Simulation Tools

March 7, 2012
