This research project will extend the illustrative and informal models of iteration in engineering design that are available at present. Formal methods for guiding the refinement of engineering designs at each iteration will be developed that permit the designer to make better decisions during the design process. The set-based representation and manipulation of uncertainties in engineering design developed previously will be extended to combine the imprecise results from each design step to guide the next step. Since engineering design informally converges to a solution (in most cases) now, we believe that developing a formalism for guiding the design refinement will also produce an understanding of the conditions under which the iterations are convergent. This, of course, has profound implications for design, in that very early indications of the possibility of convergence of several different candidate designs may be able to guide the designer to pursue (at least initially) those candidates with the best indications of convergence.

该研究项目将扩展目前可用的工程设计中的说明性和非正式的迭代模型。 将开发在每次迭代中指导工程设计细化的正式方法，使设计人员能够在设计过程中做出更好的决策。 先前开发的工程设计中基于集合的不确定性表示和操纵将得到扩展，以结合每个设计步骤的不精确结果来指导下一步。 由于工程设计现在（在大多数情况下）非正式地收敛于解决方案，因此我们相信，开发用于指导设计细化的形式主义也将产生对迭代收敛条件的理解。 当然，这对设计具有深远的影响，因为几种不同候选设计收敛可能性的早期迹象可能能够指导设计者追求（至少在最初）那些具有最佳收敛迹象的候选者。
