An Architecture for a Generic Data-Driven Machine Shop Simulator

October 1, 2002
Author(s)
Charles R. McLean, Albert T. Jones, Yung-Tsun Lee, Frank H. Riddick
In most cases, the effort required to develop a meaningful simulation for a small machine shop exceeds the resources available. Small shops typically do not have staff with appropriate technical qualifications required to develop custom simulations of

An IDEF1X Information Model for a Supply Chain Simulation

October 1, 2002
Author(s)
Yung-Tsun Lee, Shigeki Umeda
This paper describes the scope and configuration of the simulation model that is under development for a manufacturing supply chain. An information model that serves as a neutral interface specification is also presented in the paper. The supply chain

Haptics in Virtual Nanoscale Assembly

August 1, 2002
Author(s)
Kevin W. Lyons, Yung-Tsun Lee
Assembly operations at the nanometer scale differ from the conventional scale (greater than millimeter)assembly operations in two important aspects. Firstly, the continuium assumption in the assembly components does not apply. We clearly have to account

Interface Specification for a Supply Chain Simulation

November 1, 2001
Author(s)
Yung-Tsun T. Lee, Shigeki Umeda
This paper describes the scope and configuration of the simulation model that is under development for a manufacturing supply chain. An information model that serves as a neutral interface specification is also presented in the paper. The supply chain

A Preliminary Information Model for a Supply Chain Simulation

May 1, 2001
Author(s)
Shigeki Umeda, Charles R. McLean, Yung-Tsun T. Lee
This paper provides an overview of the information model that is under development for the simulation of a manufacturing supply chain. The supply chain simulation is being developed to validate interface specifications as part of the Intelligent

Information Model for Machine Tool Performance Tests

November 1, 2000
Author(s)
Yung-Tsun T. Lee, M A. Donmez, Johannes A. Soons
This report specifies an information model of machine tool performance evaluation tests. The information model provides a mechanism capable of describing the properties and results of machine tool performance tests. The objective of the information model

Activity Model: Ship Repair and Conversion

July 1, 2000
Author(s)
Yung-Tsun Lee, Swee K. Leong, Charles R. McLean
This document presents an activity model that identifies the functions involved in the ship repair and conversion industry, and the information flows required to perform those functions. The activity model presented in this document is using the Integrated

Management Data Specification for Supply Chain Integration

July 1, 2000
Author(s)
Yung-Tsun Lee, Shigeki Umeda
This document specifies a framework of communication data in a supply chain system, which is viewed as a virtual enterprise. First presented is a requirement analysis to identify the information necessary to represent the communication for the produciton

Information Modeling: From Design to Implementation

September 1, 1999
Author(s)
Yung-Tsun T. Lee
Today's manufacturing industry greatly relies on computer technology to support activities throughout a product's life cycle. Effective and efficient information sharing and exchange among computer systems have been critical issues. Formal information

Production Systems Engineering: Requirements Analysis for Discrete-Event Simulation

June 1, 1998
Author(s)
Anna Bartolotta, Charles R. McLean, Yung-Tsun T. Lee, Albert W. Jones
This document describes the results of the requirement analysis phase for a neutral interface specification to discrete event simulation software. The interface specification should provide a neutral mechanism capable of describing input data to a discrete

Requirements Analysis: Process Plan Specification - Workstation Level

June 1, 1998
Author(s)
Kimberley Ellis, Albert T. Jones, Yung-Tsun Lee
The Computer-Aided Manufacturing Engineering (CAME) program is developing a number of integrated software toolkits for design, manufacturing engineering, and production operations. One of these toolkits is the Manufacturing Engineering ToolKit (METK). The
