Shop Data Model and Interface Specification

January 1, 2005
Author(s)
Charles R. McLean, Yung-Tsun Lee, Guodong Shao, Frank H. Riddick
This paper presents an information model that provides neutral data interfaces for integrating machine shop software applications with simulation. The model is presented using the Unified Modeling Language (UML) and the Extensible Markup Language (XML).

An Architecture and Interfaces for Distributed Manufacturing Simulation

November 1, 2004
Author(s)
Charles R. McLean, Frank H. Riddick, Yung-Tsun Lee
This paper presents an overview of a neutral reference architecture and data model for integrating distributed manufacturing simulation systems with each other, with other manufacturing software applications, and with manufacturing data repositories. Other

A Neutral Data Interface Specification for Simulating Machine Shop Operations

September 1, 2004
Author(s)
Yung-Tsun Lee, Charles R. McLean
In most cases, the effort required to develop a meaningful simulation for a small machine shop exceeds the resources available. Machine shops typically do not have staff with appropriate technical qualifications required to develop custom simulations of

Design Specifications of a Generic Supply Chain Simulator

August 1, 2004
Author(s)
Shigeki Umeda, Yung-Tsun Lee
This paper describes a design specification for a generic, supply-chain-simulation system. The proposed simulation system is based on schedule-driven and stock-driven control methods to support the supply chain management. The simulation system includes

A Database Application for Manufacturing Simulation System Integration

January 1, 2004
Author(s)
Yan Luo, Yung-Tsun Lee
This report describes a database model currently under development at the Manufacturing System Integration Division (MSID) of the National Institute of Standards and Technology (NIST). The database model contains a set of tables that are mapped onto the

A Database Design for the Machine Shop Information Model

January 1, 2004
Author(s)
Yung-Tsun Lee, Yan Luo
This report describes a database model currently under development at the Manufacturing System Integration Division (MSID) of the National Institute of Standards and Technology (NIST). The database model contains a set of tables that are mapped onto the

Manufacturing Data Validation Through Simulation

October 1, 2003
Author(s)
Guodong Shao, Yung-Tsun Lee, Charles R. McLean
In order to ensure that the process plan and numerical control (NC) programs are complete and correct before jobs are released to the shop floor, manufacturing industry needs a validation system that has visualization and analysis capabilities. A prototype

A Neutral Information Model for Simulating Machine Shop Operations

August 1, 2003
Author(s)
Yung-Tsun Lee, Charles R. McLean, Guodong Shao
Small machine shops typically do not have the resources to develop custom simulations of their operations or data translators to import their data from other manufacturing software applications. This paper presents an overview of an information model

Software Architecture of Virtual Environment for Nano Scale Assembly (VENSA)

August 1, 2003
Author(s)
Kevin W. Lyons, Yung-Tsun T. Lee
Virtual Environment (VE) uses various computer-generated media to let a user experience situations that are temporally and spatially prohibiting. The information flow between the user and the VE is bi-directional. The user can influence the environment

An Interface Data Model Supporting Manufacturing Simulation

June 1, 2003
Author(s)
Yung-Tsun Lee, Yan Luo, Charles R. McLean
Simulation technology is underutilized by the manufacturing industry. Standard data interfaces, among simulation modules or between simulation and other software applications, could make information sharing effective and efficient, and hence promote

An Open Framework for the Assembly of Micro- and Nano-Scale Artifacts

June 1, 2003
Author(s)
Shaw C. Feng, Yung-Tsun Lee, Kevin W. Lyons
The design and manufacture of miniature devices have been increasing in both research laboratories and industry. The sizes of the devices continue to decrease to the nanometer scale. At the same time, the complexity of those devices has increased. To

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
