CIMMS Focused Workshop on Uncertainty Management in Engineering Design

Theme | Schedule | Participants | Invitation | CIMMS Home

The Center for Integrative Multiscale Modeling and Simulation is pleased to present the CIMMS Focused Workshop on Uncertainty Management in Engineering Design.

One of the objectives of CIMMS is the development of fundamental tools for the analysis of multiscale systems. It includes, for example, geometric multiscale modeling, multiscale algorithm development and hierarchy based algorithms.

CIMMS provides a forum in which workers in the physical modeling aspects of multiscale systems and those from the computational community can interact with researchers from industry.

Some considerations that are relevant for this endeavor are as follows. When one is simulating complex multiscale systems, it is critical to develop methods for validating the computation. Since experience shows that one scale can dramatically influence other scales, the checking of the validity is a basic and important question. The resolution of these problems is expected to involve tools such as error analysis and interval arithmetic across scales. Part of the complication is that often the answer will depend on the measure of validation one uses; a model may predict some gross quantities very well but fail at another scale of fidelity, so that a systematic way of passing through scales and keeping measures of validation is important.

In addition, realistic models of systems must take into account the fact that the models themselves as well as the parameters that are used may be uncertain. The uncertainties can be one of neglected details at a certain scale as well as stochastic effects. Techniques from linear control theory have made considerable progress on such methods and another objective of CIMMS is to encourage the development of such methods for nonlinear systems and their application to both modeling across scales as well as to computational analysis and concrete problems of industrial importance.


Theme
The theme of the workshop is the role of uncertainty, computation and dynamics in engineering design, the development of emerging tools and the inclusion of uncertainty in descriptions of physical systems.

Special Invitation (directions)

We are pleased to invite you (or your delegate) to attend a one-day, CIMMS-sponsored workshop on May 23, 2002, from 8:55 am to 6:00 pm. CIMMS (The Center for Integrative Multiscale Modeling and Simulation) is a Caltech research center intended to focus, nurture, and develop research activities in a wide range of topics in multiscale phenomena ranging from physical and mathematical modeling to computational algorithms.

The invitational workshop, "Uncertainty Management in Engineering Design," will be held on the Caltech campus in the Winnett Student Center, which is located on the second floor of building 51.

Participants in the workshop will focus on the role of uncertainty in engineering design, what types of tools are under development, and how we might include uncertainty in descriptions of physical systems. We have invited speakers from both academia and industry who will present the full scope of current problems and current solution methods.

Caltech faculty from the departments of Mechanical Engineering, Applied and Computational Mathematics, Control and Dynamical Systems, Aeronautical Engineering, BioEngineering, Physics, Applied Physics, and Computer Science will participate.

Speakers will present overviews in several different research topics that include but are not limited to:

Academia:

Subdivision methods, other topics from Opaal
Materials modeling, scientific computation,
Fluids modeling, dynamics.

Industries:

Building HVAC
Fuel cells
Flight systems
Satellite systems
Materials
Design
Computer aided design

Through both the presentations and informal discussion opportunities, we hope to identify areas of mutual research objectives. This workshop should ultimately serve as a springboard for further discussion, association, and long-term interaction with Caltech.

We invite participation from you and your colleagues for this prestigious event. If you cannot personally attend, please recommend a representative from your group. We will send out more information regarding the event as we get closer to it so please watch for details in upcoming announcements. If you have any questions or would like to R.S.V.P., please contact Jill Andrews, 626.395-6254 or jandrews@caltech.edu.

We look forward to hearing from you.

Best regards,

Jerrold E. Marsden, Director, CIMMS
