本研究提出了一种新的基于集合的初步工程设计方法，本质上包含各种来源的不确定性。其目标是实现设计的灵活性和鲁棒性，同时捕捉设计师的喜好。该设计方法包括三种计算方法：（1）集合表示法，用于描述设计方案和性能要求的变化程度，从而能够根据设计者的偏好结构来处理不确定的设计方案和性能要求;（2）集合传播法获得不确定设计方案所能达到的性能可能性，从而探索更广阔的设计可能性;（3）集合缩小方法以生成可行解的范围集合（即，鲁棒且灵活的解决方案集）而不是单点解决方案，该单点解决方案通过消除不可行的和较差的解决方案子集来满足不断变化的性能要求集，从而允许设计容易地适应不断变化的条件。最后，通过成功实现真实的工业设计问题（即，车辆侧门结构设计）。
This study proposes a new set-based design approach for preliminary engineering design that intrinsically contains various sources of uncertainties. The goal is to achieve design flexibility and robustness while capturing designer’s preference. The proposed design approach includes three computational methods: (1) set representation method to specify the varying degree of desirability of a ranged set of design solutions and performance requirements, thereby enabling the manipulation of uncertain design solutions and requirements based on designer’s preference structure; (2) set propagation method to obtain performance possibilities achievable by uncertain design solutions, thus exploring a broader design possibilities; (3) set narrowing method to generate a ranged set of feasible solutions (i.e., robust and flexible solution set) instead of single point solution that satisfies changing sets of performance requirements by eliminating infeasible and inferior subsets of solutions, thus allowing designs to be readily adapted to changing conditions. Finally, the proposed design approach is illustrated with a successful implementation of real industrial design problem (i.e., vehicle side-door structure design) in the simulation-based design environment.
