Efficient and consistent simulation data management is indispensable and a challenging problem to be solved in modeling manufacturing and business processes. An extensible markup language (XML) based simulation interface specification is being developed by the National Institute of Standards and Technology (NIST). The proposed NIST document contains a prototype generic simulation data specifica...

In all types of communication, the ability to share information is often hindered because the meaning of that information can be affected drastically by the context in which it is viewed and interpreted. This is especially true among manufacturing simulation systems because of the growing complexity of manufacturing information and the increasing need to exchange this information not only among...

Today, after more than four decades of presence in the manufacturing industry, we can conclude that simulation as a technology has become extremely powerful, that simulation software – although not entirely adequate – still appears very capable, and that methodologies for performing simulation projects are reasonably well-developed and documented. Turning to the context and scope of this thesis...

The research area “Virtual Manufacturing” can be defined as an integrated manufacturing environment which can enhance one or several levels of decision and control in manufacturing process. Several domains can be addressed: Product and Process Design, Process and Production Planning, Machine Tool, Robot and Manufacturing System. As automation technologies such as CAD/CAM have substantially shor...

Semiconductor manufacturing industry has elevated cost in productions. Improvement of production efficiency is always an important goal for manufacturers. Run-to-run control has been widely used in batch manufacturing processes to reduce variations. Threaded exponentially weighted moving average (threaded-EWMA) run-to-run control is an important and stable control scheme. In this paper, we stud...

Manufacturing modeling and simulation has historically been equipment-centric. This equipmentcentric view is an imperfect representation of a realworld factory where Operators’ decision-making processes drive manufacturing. This paper evaluates rudimentary enhancements to a simulation tool allowing for Operator-centric modeling. The results of these experiments indicate a significant improvemen...

Successful uses of simulation proliferate throughout manufacturing and the papers presented here illustrate the range of uses suitable for simulation models. The forum format allows participants to exchange success stories of using simulation in a variety of applications.

Simulation of a manufacturing cell requires the different kinds of simulation models of manufacturing stations that constitute the cell. However, a commercial station simulator only gives simulation mechanism for a limited kind of station, and its simulation model is fixed to the engineer. On the other hand, it is inefficient for the engineer to develop the dedicated simulation model and mechan...

Product quality and cost efficiency continue to grow in importance for the wood-based composites industry. The complex dynamics of the manufacturing process lends itself to the adoption of simulation models. Simulation models may be used to understand and manipulate the many parameters involved in the manufacturing process. However, most of the simulation models that have been developed over th...

Recently there has been an increased focus on the environmental aspects of the manufacturing industry across the world. Boeing and the National Institute of Standards and Technology (NIST) have studied the incorporation of Life Cycle Analysis (LCA) parameters into Discrete Event Simulation (DES) as a means to analyze sustainable performance in the manufacturing area. For machining, accurate ana...
