An Integrated Simulation Environment for Incident Management Training

September 1, 2007
Author(s)
Charles R. McLean, Sanjay Jain, Yung-Tsun T. Lee, Guodong Shao
Simulation and gaming can support decision making through all phases of incident management including prevention, preparedness, response, recovery, and mitigation. A number of gaming and simulation tools have been developed for the purpose but they

Applying Serious Games to Intelligence Analysis

September 1, 2007
Author(s)
Don E. Libes, Theresa O'Connell
Knowledge from game design appears to offer new methods for software instruction and use that would traditionally require long, expensive, and not always effective training. In this paper, we explore the possibility of applying such knowledge to the field

Integration of Incident Management Simulation-based Training Applications

September 1, 2007
Author(s)
Charles R. McLean, Yung-Tsun T. Lee, Sanjay Jain
The nation's incident management personnel and emergency responders need to work in a coordinated, well-planned manner to best mitigate the impact of natural and man-made disasters. They need to be trained and be ready to act in view of increased security

Science based Information Metrology for Engineering Informatics

September 1, 2007
Author(s)
Sudarsan Rachuri
Engineering informatics is the discipline of creating, codifying (structure and behavior that is syntax and semantics), exchanging (interactions and sharing), processing (decision making), storing and retrieving (archive and access) the digital objects

Standardized Data Exchange of CAD Models with Design Intent

September 1, 2007
Author(s)
Junhwan Kim, Mike Pratt, Raj G. Iyer, Ram D. Sriram
Modern CAD systems generate feature-based product shape models with parameterization and constraints. Until recently, standards for CAD data exchange among different CAD systems were restricted to the exchange of pure shape information. These standards

Sustaining Engineering Informatics: Toward Methods and Metrics for Digital Curation

September 1, 2007
Author(s)
Joshua Lubell, Eswaran Subrahmanian, Mahesh Mani, Sudarsan Rachuri
Ensuring the long-term usability of engineering informatics (EI) artifacts is a challenge, particularly for products with longer life cycles than the computing hardware and software used for their design and manufacture. Addressing this challenge requires

The Helium Ion Microscope: A New Tool for Nanotechnology and Nanomanufacturing

September 1, 2007
Author(s)
Michael T. Postek, Andras Vladar, John A. Kramar, L A. Stern, John Notte, Sean McVey
Helium Ion Microscopy (HIM) is a new, potentially disruptive technology for nanotechnology and nanomanufacturing. This methodology presents a potentially revolutionary approach to imaging and measurements which has several potential advantages over the

Distributed Simulation - A Necessity or Ivory Tower Research?

August 1, 2007
Author(s)
Charles R. McLean
There is a growing need for the nation to be better prepared to deal with both man-made and natural disasters. The responses to the attacks on the World Trade Center and Hurricane Katrina are strong evidence of this need. Effective emergency response

RoHS Harmonization - Progress Toward a Single Global Standard?

July 13, 2007
Author(s)
Eric D. Simmon
The lack of global harmonization of RoHS initiatives has been a major headache for the electronics industry, to say the least. A number of organizations have been working very diligently to move standards closer together, with the hope that at some point

A Pilot Implementation of the Core Manufacturing Simulation Data Information Model

July 1, 2007
Author(s)
Yung-Tsun T. Lee, Swee K. Leong, Frank H. Riddick, Marcus Johansson, Bjoern J. Johansson
Interoperability between manufacturing software applications and simulation is currently extremely limited, and it has been recognized that there is a great need for methods to improve interoperability. The Core Manufacturing Simulation Data (CMSD)

A Test Implementation of the Core Manufacturing Simulation Data Specification

July 1, 2007
Author(s)
Marcus Johansson, Swee K. Leong, Yung-Tsun T. Lee, Frank H. Riddick, Guodong Shao, Bjoern J. Johansson, Anders Skoogh, P Klingstam
This paper describes an effort of testing the Core Manufacturing Simulation Data (CMSD) information model as a neutral data interface for a discrete event simulation model developed using Enterprise Dynamics. The implementation is based upon a model of a

An Ontology for Assembly Representation

July 1, 2007
Author(s)
Xenia Fiorentini, Iacopo Gambino, V.C. Liang, Sebti Foufou, Sudarsan Rachuri, Mahesh Mani, Conrad E. Bock
Mechanical assemblies are systems composed of modules that are either subassemblies or parts. Traditionally an assembly information model contains information regarding parts, their relationships, and its form. But it is important that the model also

Data Exchange of Parametric CAD Models Using ISO 10303-108

July 1, 2007
Author(s)
Junhwan Kim, Mike Pratt, Raj G. Iyer, Ram D. Sriram
Modern CAD systems generate feature-based product shape models with parameterization and constraints. Until recently, standards for CAD data exchange among different CAD systems were restricted to the exchange of pure shape information. These standards

Distributed Simulation for Interoperability Testing Along the Supply Chain

July 1, 2007
Author(s)
Sanjay Jain, Frank H. Riddick, Andreas Craens, Deogratias Kibira
The need for interoperability of information systems among supply chain partners has been recognized. A number of standards have been or are being developed to ensure interoperability of applications used along the sup-ply chain. An associated need for

Generic Simulation of Automotive Assembly for Interoperability Testing

July 1, 2007
Author(s)
Deogratias Kibira, Charles R. McLean
Computer simulation is effective in improving the effi-ciency of manufacturing system design, operation, and maintenance. Most simulation models are usually tailored to address a narrow set of industrial issues, e.g., the intro-duction of a new product. If

Standards-Based Semantic Middleware

July 1, 2007
Author(s)
Nenad Ivezic, Boonserm Kulvatunyou, Marko Vujasinovic, Pat Snack, Zuran Marjanovic, Hyunbo Cho
We describe a novel semantics-based architecture for standards-based approaches to interoperable applications. The paper includes our experiences in prototyping the proposed architecture and demonstrating the resulting semantic middleware capability. This
