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

这笔赠款为2004年9月15日至9月17日在佐治亚州萨凡纳的佐治亚理工学院萨凡纳校区举办的可靠工程计算研讨会提供了部分资金。该研讨会的目的是促进可靠工程计算领域的跨学科研究。为实现这一目标，拟议的讲习班将汇集来自不同工程领域以及来自数学和计算机科学的研究人员，以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继续提供跨学科建议奠定基础。可靠的工程计算要求计算系统适应几种不确定和误差来源，重点放在自我验证方法及其相关的计算复杂性上。工程学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)描述物理系统的数学模型的适当性，(2)数学模型到计算框架中的离散化，(3)问题输入参数的不精确知识，以及(4)计算机有限算法的本质引入的误差。研讨会的主要主题包括(1)算法和计算的可靠性测量，(2)工程计算中各种误差源的集成，以及(3)将不确定性融入设计。虽然研讨会关注的一些方面包括在一般数值方法、计算机科学和工程学的会议上，但没有人将所有这些学科统一起来，专注于工程设计计算。这个工作坊在结合计算机科学、数学和工程分析来讨论工程计算的可靠性方面是独一无二的。工作坊将在分析和设计中讨论可靠的工程计算的不同方面。

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.
