在本文中，我们建议使用基于概率的设计模型作为在设计过程中提供灵活性的基础，使设计能够随时适应不断变化的条件。我们提出的方法可用于开发满足一系列设计需求的一系列解决方案。同时，设计师可以根据自己的喜好指定一系列设计性能的不同程度的可取性。引入设计偏好指数（DPI）作为衡量柔性设计优劣的设计指标。为我们的工作提供基础的是设计性能的概率表示，稳健设计概念的应用，以及折衷决策支持问题（DSP）作为多目标决策模型的利用。以两杆结构设计为例，说明了我们的方法。本文的重点是介绍基于概率的设计模型，而不是示例问题本身的结果。
In this paper we propose the use of a probabilistic-based design model as a basis for providing the flexibility in a design process that allows designs to be readily adapted to changing conditions. Our proposed approach can be used to develop a range of solutions that meet a ranged set of design requirements. Meanwhile, designers are allowed to specify the varying degree of desirability of a ranged set of design performance based on their preferences. The Design Preference Index (DPI) is introduced as a design metric to measure the goodness of flexible designs. Providing the foundation to our work are the probabilistic representations of design performance, the application of the robust design concept, and the utilization of the compromise Decision Support Problem (DSP) as a multiobjective decision model. A two-bar structural design is used as an example to demonstrate our approach. Our focus in this paper is on introducing the probabilistic-based design model and not on the results of the example problem, per se.
