Decision Support for Seismic Performance Evaluation

在结构生命周期的所有阶段，工程师都面临着复杂决策的艰巨挑战，包括开放式和结构不良的问题，不确定的甚至可能不完整的数据，以及不同规模和精细化程度可能不相容的模型。总体而言，这项研究的目标是开发支持结构工程综合决策的形式计算方法。具体地说，这些方法将在原型决策支持系统中实现，该系统利用联合认知系统中工程师和计算机的互补优势。它的设计将基于三个主要概念-(1)用于评估备选方案和支持假设分析的优化；(2)用于解决结构模型综合、可伸缩性、模型更新和不确定性传播的子组件方法；以及(3)在面向对象的高性能分布式计算框架中实现。将使用一系列简单和现实生活中的测试案例来评估所提出的原型。

At all stages in the structural life-cycle, engineers are faced with the formidable challenges of complex decision-making, including open-ended and ill-structured problems, uncertain and perhaps incomplete data, and models with varying scales and levels of refinement that may be incompatible. Overall, goal of this research is to develop formal computational approaches that support comprehensive decision making in structural engineering. Specifically, these approaches will be realized in a prototype decision support system that draws on the complementary strengths of the engineer and the computer in a joint-cognitive system. Its design will be based on three major concepts- (1) optimization for evaluating alternatives and supporting what-if analyses; (2) sub-component approach to address structural model synthesis, scalability, model updating and uncertainty propagation; and (3) implementation in an object-oriented framework of high performance distributed computing. A series of simple and real-life test cases will be used to evaluate the proposed prototype.
