The UK Net Zero Strategy published in October 2021 reflects the urgency of action needed to avoid climate catastrophe. The net zero journey outlined therein addresses economy and emissions reduction in all sectors, with the specific challenge in aviation a notable element. Global aviation is currently responsible for 2% of emissions with 90% currently from aircraft operations, and this will grow progressively as air transportation grows. In response to this technology and policy are changing rapidly offering both opportunity and challenge, but the standard design systems and processes in practice today are insufficiently agile to support the current need for novel designs that can adapt to these rapidly changing future needs. With current approaches solutions get locked in early based on the available technology level, and optimised around that technology, and consequently have limited opportunity for upgrade and enhancement through operational life, which in the case of aerospace is decades. But delivery of net zero demands radical change quickly. Agile and adaptable design systems are needed to help develop solutions that can be easily upgraded to use advanced technology as it emerges.The key here is that constraints are needed to to allow a baseline solution to be found, but in then optimising around this baseline the constraints become a barrier to future enhancements. To allow future variation without redesign needs new capability. In particular capability to map and measure a design space and to subsequently be able to dynamically change the constraints was found to be a core need for progress in this area. The mapping and measurement capability is needed to understand how constraints are influencing the design at this point in time, and the capability to deal with changing constraints to allow understanding of how the design could change with new technology advance or policy changes. The four research questions emerging from this are therefore:1. Navigation of Dynamic Design Spaces: How can constraints be represented in a design model such that a changing design space can be navigated and the constraints driving or limiting the design can be identified, and their influence on the design quantified?2. Evolving Constraints over time: How can constraints be allowed to evolve over time and their influence on the design solutions over time captured, including ability to prioritise requirements/constraints?3. Measurement and Evaluation of Solution Paths: What metrics are appropriate for maintaining a set of time-history linked solutions open to further development? 4. Keeping Design Options Open: How can design options be kept open, and how cantechnology changes/policy changes or removal over a long time period be studied?In DECIDE for Net Zero constraints will be permitted to evolve just as every part of the design can. In doing this the design context itself will evolve, creating new fitness landscapes for product evolution. Contrary to standard practice today which is to optimise as far as possible, the aim here is to generate a diverse population of solutions that will have many individuals that survive major disruptions even if some may fail. This is moving significantly beyond current concepts of robust design. This variation of constraints requires a completely novel design system architecture using time history dependent genetics. Geometric analogies for design spaces will allow innovative design tools to support exploration of design spaces in a more meaningful way and the latest bio-inspired methodologies will allow exploration of how products evolve in the context of ever-changing constraints. With this capability robust baseline designs can be developed that will enable the fastest transition to net zero, for example a more modular airframe that can accept plug and play solutions for hydrogen or electric propulsion systems and energy supply which are easy to cost effective to maintain.

英国净零战略于2021年10月发表，反映了避免气候灾难所需的行动紧迫性。其中概述的净零旅程解决了所有部门的经济和排放减少，而在航空中的具体挑战是一个显着的因素。目前，全球航空造成了2％的排放量，目前来自飞机运营的90％，随着航空运输的增长，这将逐步增长。回应这一技术和政策正在迅速提供机会和挑战，但是当今实践中的标准设计系统和流程不足以支持当前对可以适应这些快速变化的未来需求的新颖设计需求。随着当前的方法，解决方案会根据可用的技术水平锁定，并围绕该技术进行了优化，因此，通过运营生活的升级和增强机会有限，在航空航天中，这是数十年的。但是，净净的净额需要迅速变化。需要敏捷和适应性的设计系统来帮助开发解决方案，这些解决方案可以轻松升级以使用先进的技术出现。这里的关键是，需要限制以允许找到基线解决方案，但是在围绕此基线进行优化时，约束成为未来增强功能的障碍。为了允许未来的变化而无需重新设计，需要新的功能。特别是能够映射和测量设计空间，并随后能够动态更改约束是该领域进步的核心需求。需要进行映射和测量能力，以了解此时的约束如何影响设计，以及处理不断变化的约束的能力，以允许了解设计如何随着新技术的推进或政策变化而发生变化。因此，从中出现的四个研究问题是：1。动态设计空间的导航：如何在设计模型中表示约束，从而可以将不断变化的设计空间导航，并且可以识别驾驶或限制设计的约束，以及它们对设计量化的影响？2。随着时间的流逝，不断发展的约束：如何随着时间的推移而允许约束进化及其对设计解决方案的影响，随着时间的推移捕获的设计解决方案，包括优先级/约束的能力？3。解决方案路径的测量和评估：哪些指标适合维持一组时间历史的链接解决方案，以开发进一步开发？ 4.保持设计选项打开：如何保持设计选项的打开状态，以及长期研究的综合性更改/政策更改或删除？在决定净零约束条件的决定中，将像设计的每个部分一样发展。在执行此操作时，设计环境本身将发展，为产品演变创造新的健身景观。与当今的标准实践相反，该实践要尽可能优化，这里的目的是产生各种各样的解决方案，即使有些人可能失败，也将有许多人在重大破坏中生存。这超出了当前强大设计的概念。约束的这种变化需要使用依赖时间历史的遗传学的完全新颖的设计系统体系结构。设计空间的几何类比将允许创新的设计工具以更有意义的方式支持探索设计空间的探索，而最新的生物启发的方法将允许探索在不断变化的约束的背景下如何发展产品。有了这种能力，可以开发出强大的基线设计，从而可以使净净的最快过渡到净零，例如一个更模块化的机身，可以接受易于维护的氢或电推进系统和能源供应的插头解决方案，易于维护。
