Standard interfaces could help reduce the costs associated with simulation model construction and data exchange between simulation and other software applications -- and thus make simulation technology more affordable and accessible to a wide range of potential industrial users. Currently, small machine shops do not typically use simulation technology(More)
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 currently under development at the National Institute of Standards and Technology (NIST) to address this(More)
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 modeling languages that describe information requirements unambiguously is an enabling technology that(More)

PREFACE The High Performance Computing and Communication (HPCC) program was formally established by the High Performance Computing Act of 1991 (Public Law 102-194). The goal of this program is to accelerate the development of future generations of high performance computers and networks and the use of these resources in the government and throughout the(More)
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 three processing modes: business process flows, material process flows, and information process flows.(More)
Simulation technology has been demonstrated to be an effective tool for reducing costs, improving quality, and shortening the time-to-market for manufactured goods in the manufacturing industry. But, there are a number of technical and economic barriers that hinder the use of this technology in the manufacturing industry. The cost of developing,(More)
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 paint shop at a Volvo Car Corporation plant in Sweden. The model is built for a Swedish research project(More)
Input Data Management (IDM) is a time consuming and costly process for Discrete Event Simulation (DES) projects. In this paper, a methodology for IDM in DES projects is described. The approach is to use a methodology to identify and collect data, then use an IDM software to extract and process the data. The IDM software will structure and present the data(More)
Developing mechanisms for the efficient exchange of information between simulations and other manufacturing tools is a critical problem. For many areas of manufacturing, neither representations for the information nor mechanisms for exchanging the information have been agreed upon. Manufacturing plant layout is one such area. The Core Manufacturing(More)
