项目摘要

The objective of this research is to develop a technique that allows a designer to play an active role in the design optimization process. This research combines fast optimization methods, based on sensitivity analysis, with virtual reality techniques to provide an interactive method for design optimization. Fast optimization methods are needed to allow large design problems to be investigated in an interactive time frame. Virtual reality techniques provide an interactive environment for the designer to investigate multiple design changes. Keeping the designer active in the design process allows the designer to use all of his/her prior knowledge about the problem to be brought to bear to achieve a viable, optimal solution to the problem in a timely manner. Design is an interactive process that often involves trade- offs between competing performance criteria. For example, designers strive to design vehicles that are both lightweight and strong. Design of large structural systems is accomplished through the aid of sophisticated optimization software. Currently, the interaction a designer has with the optimization process is limited to the initial stages of problem definition, where the designer specifies an objective function, design parameters, and constraints. As the design process progresses, design objectives and constraints are often modified based on the designer's experience, in order to achieve a viable solution.

这项研究的目的是开发一种技术，使设计人员在设计优化中发挥积极作用，过程这项研究结合了快速优化方法，基于敏感性分析，虚拟现实技术，以提供交互式设计优化方法。快速优化需要一些方法来解决大型设计问题，在互动的时间框架内进行调查。虚拟现实技术为设计者提供了一个交互式环境，调查多个设计变更。让设计师保持活跃在设计过程中允许设计师使用他/她的所有关于问题的先验知识，以实现及时找到解决问题的最佳方案。设计是一个互动的过程，往往涉及贸易- 竞争性的性能标准之间的差距。比如说，设计师们努力设计既轻便又强壮. 大型结构系统的设计是通过先进的优化软件的帮助。目前设计人员与优化过程的交互是有限的到问题定义的初始阶段，设计师指定目标函数、设计参数，以及约束随着设计过程的进行，设计目标和约束经常根据设计者的经验，以实现一个可行的解决方案。
