Simulation-Based System Design Laboratory

Overview

Our research objective is to develop, test, and implement effective and efficient simulation techniques for modeling, evaluating, and optimizing systems in order to improve decision-making throughout the system development life cycle. Simulation is an important tool for modeling and predicting the performance of systems when analytical models do not exist or perform poorly. In addition, simulation provides powerful ways to visualize the behavior of a complex system before it is constructed.

Research focus

• Manufacturing process design

• Manufacturing system design

• Production planning and control

• Public health emergency preparedness planning

• Homeland security

• Robot design

• Planning and control of autonomous systems

• Virtual environment based training

Facilities

The Simulation-Based System Design Laboratory has state-of-the-art personal computers with network access to the optimization, web server development, and simulation software needed to conduct this research. Virtual environment hardware in the lab includes the following:

• Four Optical Position Trackers (Cameras) — These are arranged around a room and used to track the position of infrared lights (LEDs) on the wand and the Head Mounted Display (HMD).

• Two Wireless InertiaCube3s — Used in orientation tracking. One is mounted on the wand and the other on the HMD.

• One nVis nVisor SX Head Mounted Display — Contains two miniature lenses and LCD displays, one set for each eye. Slightly different images are sent to each LCD creating a realistic 3D visual effect.

• One Wand (wireless presenter/mouse) — Used to communicate with the system and manipulate objects; controls a virtual laser pointer inside the virtual environment.

• One Video Splitter — Allows simultaneous feeding of images to HMD, monitor, and projector.

• Three infrared light emitting diodes (LEDs) — Used in combination with Optical Position Trackers for position tracking of wand and HMD.

• Flock of Birds™ — 6 degrees of freedom wand based tracking system from Ascension Technologies.

• Pair of NEC Stereo projectors with Stewart Luxus Screenwall Box for passive stereo display — A NVIDEA FX3000 video card is used for graphics acceleration.
