Unfortunately, this technology still remains largely underutilized by industry today. This paper suggests benefits to industry resulting from the widespread, pervasive implementation of manufacturing simulation technology. Potential simulation impact areas are closely intertwined with strategic manufacturing. Yet, a number of factors currently inhibit the deployment of simulation technology in industry today. The development of new simulation interface standards could help increase the deployment of simulation technology. Interface standards could improve the accessibility of this technology by helping to reduce the expenses associated with acquisition and deployment, minimize model development time and costs, and provide new types of simulation functionality that are not available today.

The application of the proposed framework results in the identification and specification of four different elements in the context of semiconductor fabs: (1) market sector, (2) hierarchical modeling levels, (3) simulation case studies, and (4) models and data. Three examples of the application of the proposed simulation framework are presented by using three semiconductor fab models: the Mini-fab benchmark, Measurement and Improvement of Manufacturing Capacities (MIMAC) data set 1, and the Hewlett-Packard-Wein's model. In these examples, three different case studies are presented, which consisted in the evaluation of production performance under different workforces, dispatching rules, and wafer lot release rates. The proposed simulation framework is by no means considered complete, and future additions and modifications are expected. Our current and future research is focused on the improvement of the proposed framework (e.g., design and testing of generic case studies) as well as the incorporation of the work being conducted by NIST, within the NIST's System Integration of Manufacturing Applications (SIMA) program, towards the standardization of data formats for simulation in manufacturing systems.

National Institute of Standards and Technolw WST) is working on the integration o f a software tools environment for engineering production s y s t e m s . This paper describes a process model for the engineering production systems and how that model is being used to integrate the commercial software tools into a workstation environment. The tools used to implement the environment are commercial off-the-shelf software products offered by a number o f different vendors. The project is being undertaken as a collaborative effort h e e n MST researchers, several universities, andU.S. manufacturers.
