The objective of this Small Grant for Exploratory Research (SGER)/Grant Opportunity for Academic Liaison with Industry (GOALI) project is to explore how industry and academia can collaborate to investigate the theoretical and practical feasibility of applying flexibility principles to the organization and execution of collaborative design processes. One of the foremost challenges facing product development is the need to distribute design activities across disciplines, organizations, and hierarchical scales while simultaneously managing dependencies and couplings to achieve satisfactory system-level solutions. To facilitate distributed collaboration, a flexibility-based approach is proposed in which collaborating designers exchange approximate models followed by families or Pareto sets of robust solutions that embody a spectrum of achievable tradeoffs between coupled parameters. Flexibility is embodied in the families of robust solutions from which collaborating designers may select an appropriate solution and adjust it within a set of robust bounds for maintaining system feasibility and balancing system-level objectives. The approach offers computational support for collaborative design with reduced iteration between designers, as a direct result of increased coverage of the design space, relative to single point solutions associated with most over-the-wall, MDO (multidisciplinary optimization), and hierarchical optimization methods and intervals associated with robust design approaches. It can potentially avoid extensive centralized, systems-level optimization that requires automated analysis and creates systems-level bottlenecks and computational intractability. Instead, subsystem designers are consistently in the loop, utilizing their expertise to formulate design problems and simulation models and to validate and interpret solutions. Furthermore, the generation of multiple solutions increases the likelihood of design reuse for similar problems in the future'an important practical benefit for industry. The proposed approach is high risk because its viability for non-trivial, industrial strength problems needs to be established, in light of potential barriers such as an industrial bias for rapid convergence to single point solutions and the overall human and computing resource demands relative to more conventional approaches. We plan to conduct preliminary trials with our industrial partner to identify any additional barriers and corresponding research questions aimed at investigating whether those barriers are real or simply perceived. From a theoretical perspective, we need to answer those research questions and investigate the conditions under which the method is superior to other approaches, such as conventional, over-the-wall design processes or highly centralized or MDO-style design processes.

探索性研究小额资助 (SGER)/学术界与工业界联络资助机会 (GOALI) 项目的目的是探索工业界和学术界如何合作，研究将灵活性原则应用于组织和执行的理论和实践可行性。协作设计流程。产品开发面临的最重要的挑战之一是需要跨学科、组织和层次规模分布设计活动，同时管理依赖关系和耦合，以实现令人满意的系统级解决方案。为了促进分布式协作，提出了一种基于灵活性的方法，其中协作设计人员交换近似模型，然后交换一系列稳健解决方案或帕累托集，这些解决方案体现了耦合参数之间可实现的权衡范围。灵活性体现在一系列稳健的解决方案中，合作设计人员可以从中选择适当的解决方案，并在一组稳健的范围内对其进行调整，以维持系统可行性并平衡系统级目标。该方法为协同设计提供计算支持，减少设计人员之间的迭代，这是设计空间覆盖范围增加的直接结果，相对于大多数超墙、MDO（多学科优化）和分层优化方法相关的单点解决方案以及与稳健设计方法相关的间隔。它可以潜在地避免广泛的集中式系统级优化，这种优化需要自动分析并产生系统级瓶颈和计算困难性。相反，子系统设计人员始终参与其中，利用他们的专业知识来制定设计问题和仿真模型，并验证和解释解决方案。此外，多种解决方案的生成增加了未来类似问题的设计重用的可能性——这对行业来说是一个重要的实际好处。所提出的方法具有高风险，因为考虑到潜在的障碍，例如快速收敛到单点解决方案的工业偏见以及相对于更多的人力和计算资源的总体需求，需要确定其对重要的工业强度问题的可行性。传统方法。我们计划与我们的工业合作伙伴进行初步试验，以确定任何其他障碍和相应的研究问题，旨在调查这些障碍是真实存在的还是仅仅被感知到的。从理论角度来看，我们需要回答这些研究问题，并调查该方法优于其他方法的条件，例如传统的超墙设计流程或高度集中或 MDO 式的设计流程。
