An Optimization Approach for Semantic-based XML Schema Matching

May 16, 2013
Author(s)
Jaewook Kim, Yun Peng, Nenad Ivezic, Jun H. Shin
We propose a novel solution for semantic-based XML schema matching, taking a mathematical programming approach. This method identifies the globally optimal solution for the problem of matching leaf nodes between two XML schema trees by reducing the tree-to

On Enhancing Communication of Manufacturing Service Capability Information

May 16, 2013
Author(s)
Boonserm Kulvatunyou, Nenad Ivezic, Yunsu Lee
A manufacturing service model contains both schema and schema-compliant descriptions of suppliers’ service information, such as locations, areas of specialization, capacities, certifications, software capabilities, and material processing capabilities

Size tolerancing revisited: A basic notion and its evolution in standards

May 13, 2013
Author(s)
Vijay Srinivasan, Edward P. Morse
Size is a fundamental descriptor of objects – it allows us to quantify 'how big' objects are, and to compare and classify objects based on this notion. In the world of ISO GPS (Geometrical Product Specification and Verification), size is defined much more

Engineering Change Management Concepts for Systems Modeling

April 22, 2013
Author(s)
Conrad E. Bock, Allison Barnard Feeney
A significant cost of manufactured systems arises in changing system specifications after they have been built and delivered to customers. This might be due to errors in the original specifications, feedback from customers, competition from other producers

Concept Analysis to Enrich Manufacturing Service Capability Models

March 22, 2013
Author(s)
Jun H. Shin, Boonserm Kulvatunyou, Yunsu Lee, Nenad Ivezic
When an Original Equipment Manufacturer (OEM), which makes a final product for the consumer marketplace by purchasing components from its suppliers, faces unexpected supply network failures and market events, models of suppliers’ manufacturing service

Requirements Analysis for Safer Ambulance Patient Compartments

March 22, 2013
Author(s)
Mehdi Dadfarnia, Yung-Tsun T. Lee, Allison Barnard Feeney, Deogratias Kibira
Providing emergency care services in the confined space of the patient compartment of a moving ambulance is a hazardous activity. A National Institute of Standards & Technology (NIST)/Department of Homeland Security (DHS) project is applying systems

A Semantic Framework for Systems Engineering Standards

March 19, 2013
Author(s)
Allison Barnard Feeney, David M. Price, Albert W. Jones
Systems engineers and asset managers create and maintain models of components and systems associated with long-lived, engineering assets. Component models come from many domains, disciplines and applications. System models typically require integration of

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
