We review the state of the art of process modeling for discrete event simulation, make a number of observations and identify a number of issues that have to be tackled for promoting the use of process modeling in simulation. Process models are of particular interest in model-based simulationengineering approaches where the executable simulation model (code) is obtained with the help of textual or visual models. We present an illustrative example of model-based simulation development.

Surgical simulation is embraced by many for training and skill transfer purposes of non-trivial minimally invasive procedures. Some systems utilize haptic feedback within an anatomically-correct virtual environment whereas others use manikins, synthetic components and box trainers. This paper explores the challenges and implications of reproducing the Nuss procedure on both a solely-virtual and a solely-physical environment. This work then describes a roadmap for a hybrid system that employs a best-of-both approach integrating both physical and virtual schemes to achieve a mixed reality implementation of the primary steps of the Nuss procedure.

A radically new approach to the design and implementation of high-technology, computer-driven manikin-based simulation environments for medical training is proposed. The approach utilizes a novel, component-based manikin hardware architecture currently under research for the U.S. military. A new distributed software architecture is proposed in this paper that facilitates interoperability among manikin components and provides the potential to easily integrate other real or virtual devices normally present in a real medical facility.

This paper presents a mathematical modeling technique that allows for formulating a farmer decision problem. We use fuzzy logic and binary integer programming respectively to represent the factors and decision utilities in the problem. We will briefly look at the data requirements for this model. The techniques used in determining the fuzzy rule base will be discussed. We will show the application of artificial neural networks for determining the rule base in our model. A mathematical representation of the system will be created, which can act as an approximation for any problem formulation. Finally, we will use all these techniques on a sample problem, which uses simulated data.

Real-time mirror reflection is employed in many virtual reality applications to achieve visuo-haptic collocation. Its use, however, necessitates adjustments to the original model as well any used input devices to compensate for changes due to image reversion. This paper introduces a design and implementation of a generic configuration component for virtual environments that adjusts image characteristics and haptic interfaces to accommodate such setups while preserving the properties and features of the original model. Furthermore, this work executes running multiple display viewports for the same virtual environment synchronously. This work accomplishes a significant step in the development of a surgical simulator for the Nuss Procedure surgery performed to correct Pectus Excavatum, a congenital deformity of the anterior chest wall.
With rapid development of minimally invasive surgery, proficiency with intricate skills is becoming a greater concern. Consequently, the use of out-of-operating room training has increased significantly through employ...
