Decision Support for Seismic Performance Evaluation

在结构生命周期的各个阶段，工程师都面临着复杂决策的巨大挑战，包括开放式和结构不良的问题，不确定的，也许是不完整的数据，以及可能不兼容的不同规模和细化程度的模型。总的来说，本研究的目标是开发正式的计算方法，支持结构工程的综合决策。具体来说，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。其设计将基于三个主要概念-（1）优化以评估备选方案并支持假设分析;（2）子组件方法以解决结构模型合成、可扩展性、模型更新和不确定性传播;以及（3）在面向对象的高性能分布式计算框架中实现。一系列简单的和现实生活中的测试案例将被用来评估拟议的原型。

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.
