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.

这项用于探索性研究（SGER）的小赠款/与行业联络（Goali）项目的学术联络机会的目标是探索行业和学术界如何合作调查将灵活性原则应用于组织的理论和实际可行性协作设计过程。产品开发面临的首要挑战之一是需要在学科，组织和等级标准范围内分发设计活动，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，在该方法中，协作设计师交换了近似模型，然后是家庭或帕累托的强大解决方案集，这些解决方案体现了耦合参数之间的一系列可实现的权衡。灵活性体现在健壮的解决方案的家族中，协作设计人员可以从中选择适当的解决方案，并在一组强大的范围内对其进行调整，以维持系统的可行性和平衡系统级别的目标。该方法为协作设计提供了计算支持，而设计人员之间的迭代减少了，这是设计空间增加的直接结果，相对于与大多数与大多数墙，MDO相关的单点解决方案（多学科优化）和层次优化方法以及与强大的设计方法相关的间隔。它可以避免进行广泛的集中式，系统级优化，这需要自动分析，并创建系统级的瓶颈和计算棘手性。取而代之的是，子系统设计人员一直处于循环中，利用其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，多种解决方案的产生增加了设计重用的可能性在未来对类似问题的重新利用的可能性。拟议的方法是高风险，因为鉴于潜在的障碍，例如工业偏见，即快速收敛到单点解决方案以及相对于更多的人类和计算资源需求，因此需要建立非平凡的工业力量问题的生存能力，例如工业偏见常规方法。我们计划与我们的工业合作伙伴进行初步试验，以确定旨在调查这些障碍是真实还是简单地感知的任何其他障碍和相应的研究问题。从理论的角度来看，我们需要回答这些研究问题，并研究该方法优于其他方法的条件，例如常规，墙设计过程，或高度集中或高度集中或MDO风格的设计过程。
