Research Areas and Descriptors
Background
Dr. Paredis has a broad multidisciplinary background. His research combines aspects of information technology, simulation, and modularity to support the design of mechatronic systems. He began at Tech in Fall 2002 as an Assistant Professor. Prior, he was a Research Scientist at Carnegie Mellon University.
Research
Dr. Paredis's research focuses on the use of information technology and simulation in product development. The goal is to develop an integrated IT framework that encompasses both representations and tools across the different design activities, from requirements definition and synthesis, to analysis, interpretation, and visualization. The initial focus is on the use of virtual prototyping in the context of design. As more aspects of the business process are taken into account during the product development stage, the analysis of design decisions becomes increasingly complex, suggesting a natural transition from analytical analysis tools toward simulation. To use simulation effectively for product development, it needs to be closely integrated with representations and tools for design synthesis. Simulation is therefore a pivotal component in any IT framework for product development.
A first step toward such an integrated framework is the COINSIDE methodology (Composition In Simulation and Design). COINSIDE uses a systems engineering approach based on composition of port-based component objects that include geometric and functional specifications as well as CAD models, behavioral models, and functional models. These component objects have a well-defined interface through which they can be connected and composed into larger systems. By composing component objects into configurations, designers can simultaneously design and model a complex multidisciplinary system. The framework has been demonstrated through the design of a cordless hand-drill, a MEMS accelerometer, a satellite system (with Lockheed Martin), and an automated train system (with Bombardier Transportation).
In the future, the framework will be extended in the context of the Semantic Web. The Semantic Web is an extension of the current world-wide-web in which information is given well-defined meaning (semantics), better enabling computers and people to work in cooperation. COINSIDE will also be extended by improving the user interaction through Augmented Reality. Unlike Virtual Reality in which the user is completely immersed in a virtual environment, in Augmented Reality, the user can still see the real world but with computer graphics superimposed through a see-through display. This allows multiple designers to share a holographic view of design alternatives, superimpose analysis results, and even manipulate and modify the design.
