Workshop on Reliable Engineering Computing; Savannah Campus of Georgia Institute of Technology; Savannah, Georgia; September 15-17, 2004

这笔拨款将为可靠工程计算研讨会提供部分资金，该研讨会将于2004年9月15日至9月17日在乔治亚州萨凡纳的乔治亚理工学院萨凡纳校区举行。本次研讨会的目的是促进可靠工程计算领域的跨学科研究。为了实现这一目标，提议的研讨会将汇集来自不同工程领域以及数学和计算机科学的研究人员，分享确保工程模型可靠性的方法。这样一个共同的论坛将为在可靠的工程计算中持续的跨学科建议提供基础。可靠的工程计算要求计算系统能够适应多种不确定性和错误来源，并关注自我验证方法及其相关的计算复杂性。工程的所有分支都需要可靠的计算。在机械系统模型的情况下，不确定性可能源于(1)数学模型描述物理系统的适当性，(2)数学模型离散到计算框架，(3)问题输入参数的不精确知识，以及(4)由计算机有限算法的性质引入的误差。研讨会的主要议题包括(1)算法和计算的可靠性测量，(2)工程计算中各种误差来源的集成，以及(3)将不确定性集成到设计中。虽然在一般数值方法、计算机科学和工程方面的会议中都包括了讲习班的一些重点，但没有一个会议将所有这些学科与工程设计计算的重点结合起来。本工作坊结合计算机科学、数学和工程分析来讨论工程计算的可靠性，是独一无二的。研讨会将讨论可靠工程计算在分析和设计方面的不同方面。

This grant provides partial funding for a Workshop on Reliable Engineering Computing to be held September 15 through September 17, 2004 at the Savannah Campus of Georgia Institute of Technology, Savannah, Georgia. The objective of this workshop is to promote cross-disciplinary research in the area of reliable engineering computing. For that goal, the proposed workshop will bring together researchers from various engineering fields as well as from mathematics and computer science to share methods for ensuring reliability of engineering models. Such a common forum will provide a foundation for continuing cross-disciplinary advisements in reliable engineering computations. Reliable engineering computing requires that computing systems accommodate several sources of uncertainty and errors with a focus on self-validating methods and their associated computational complexity. All branches of engineering share the need for reliable computing. In the case of a mechanical system model, uncertainties can originate from (1) The appropriateness of the mathematical model to describe the physical system, (2) The discretization of the mathematical model into a computational framework, (3) The inexact knowledge of input parameters of a problem, and (4) Errors introduced by the nature of computer finite arithmetic. The main topics of the workshop include (1) Measurement of reliability of algorithms and computations, (2) Integration of various sources of errors in engineering calculations, and (3) Integrating uncertainty into design. While some aspects of the workshop focus are included in conferences on general numerical methods, computer science, and engineering, none have united all these disciplines with a focus on engineering design calculations. This workshop is unique in combining computer science, mathematics, and engineering analysis to discuss the reliability of engineering computations.The workshop will address different aspects of reliable engineering computing in both analysis and design.
