DAFNI-ROSE

基础设施是现代社会的支柱。在我们的日常生活中，我们依赖于水和能源的供应，公路，铁路和其他交通网络，通信网络，废物处理和回收，以及我们生活和工作的建筑物。这些系统的运作方式对我们的经济、社会和物质福祉以及自然环境产生重大影响，特别是在气候变化的情况下。因此，基础设施投资被视为繁荣的驱动力。英国的国家基础设施战略制定了政府的基础设施复兴计划，公共和私人投资达数千亿英镑。然而，这对经济、社会和环境的影响尚不清楚。这种不确定性源于基础设施系统的复杂性及其与人和环境的相互作用。EPSRC支持的大学研究一直在积极开发计算机模型，以模拟基础设施并探索其影响，以支持决策。然而，研究工作的分散性以及当地资源的局限性阻碍了研究，无法将模型扩展到国家基础设施复杂性所需的范围和细节。DAFNI的愿景是让研究人员能够使用最先进的建模、模拟和可视化技术，更好地为战略思维提供信息和发展。DAFNI的开发得益于EPSRC作为英国基础设施和城市研究合作中心的一部分的800万英镑资本投资，因此研究人员可以在具有中央数据库的通用计算系统上运行模型。使用最先进的计算机，模型和模拟可以扩展到更大的覆盖范围和分辨率。合作者可以将该平台用作共享工作空间，并将来自不同部门的模型结合起来，使用来自不同来源的数据探索它们的交互。DAFNI还提供了一个遗产，一个模型和数据可以在项目生命周期之外使用的地方。2021年3月，DAFNI将完成由EPSRC资助的开发阶段，并准备向基础设施研究社区提供服务。DAFNI-ROSE在EPSRC的资源战略设备基金下，将提供必要的资源，使DAFNI免费提供给研究人员，并继续在计算和数据密集型计算的前沿发展。为DAFNI-ROSE提供的两年资金将扩大DAFNI的用途和能力，支持EPSRC的工程和相关方案。它将扩展在开发阶段建立的关系，因此更多的用户和项目可以从DAFNI的投资中获益。DAFNI-ROSE还将超越学术界，与政府和工业界建立合作关系。一个关键的用户群体是研究生，他们正在开发探索基础设施建模的技能。DAFNI-ROSE将包括一项培训计划，以培养熟悉设计和规划数据密集型工具的下一代基础设施工程师。数字双胞胎是一个改变国家基础设施效率和可靠性的机会。在数字孪生模型中，来自真实的系统的数据被输入到一个运行的计算机模拟中，以预测结果，然后可以反馈到真实的系统，以引导其进程。DAFNI-ROSE将为联合的国家基础设施数字孪生模型提供一个平台，耦合各种仿真模型，这些模型将共同促进全国范围的数字孪生模型。基础设施还影响着广泛的其他领域，包括环境，我们生活的地方和方式，我们的经济和健康。DAFNI-ROSE将开发跨学科的合作，探索建筑，人类和自然环境之间的丰富互动。

Infrastructure provides the backbone of modern societies. In our daily lives, we depend on supplies of water and energy, road, rail and other transport networks, communication networks, and waste disposal and recycling, as well as the buildings we live and work in. How these systems work has a major impact on our economic, social and physical well-being, and also on the natural environment, particularly in the light of climate change. Consequently, infrastructure investment is seen as a driver for prosperity. The UK's National Infrastructure Strategy sets out the government's plan for a renaissance in infrastructure, with hundreds of billions of pounds of public and private investment. However, the impact this will have on the economy, society and the environment, is not clearly understood. This uncertainty results from the complexity of infrastructure systems and their interaction with people and the environment.University research supported by EPSRC has been actively developing computer models to simulate infrastructure and explore its impact, to support decision making. However, research is hampered by fragmentation of effort, and limitations of local resources to scale models to the range and detail required for the complexity of national infrastructure. Particular limitations are access to quality data and combining models from different sectors together into "system-of-systems" models.DAFNI's vision is to allow researchers to use state-of-the-art modelling, simulation and visualisation to better inform and develop strategic thinking. DAFNI has been developed, thanks to an £8 million capital investment from EPSRC as part of the the UK Collaboratorium for Research on Infrastructure and Cities, so researchers can run models on a common computing system with a central repository of data. Using cutting edge computers, models and simulations can be scaled to greater coverage and resolution. Collaborators can use the platform as a shared workspace, and models from different sectors combined to explore their interactions using data from different sources. DAFNI also provides a legacy, a place where models and data can be used beyond the lifetime of a project.In March 2021 DAFNI will complete its development phase funded by EPSRC, and will be ready to deliver a service to the infrastructure research community. DAFNI-ROSE under EPSRC's Resource-Only Strategic Equipment fund, will provide resources essential to make DAFNI freely available for researchers and continue its development at the cutting edge of compute and data-intensive computing. Two years of funding for DAFNI-ROSE will widen the usage and capability of DAFNI, supporting EPSRC's Engineering and related programmes. It will extend the relationships established in the development phase, so more users and projects can reap the benefits of the investment in DAFNI. DAFNI-ROSE will also look beyond academia, engaging government and industry to build collaborations.A key group of users are research students developing skills to explore modelling of infrastructure. DAFNI-ROSE will include a programme of training to develop the next generation of Infrastructure Engineers familiar with data intensive tools for design and planning.Digital Twins are an opportunity to transform the efficiency and reliability of national infrastructure. In a digital twin, data from real systems are fed into a running computer simulation, to predict outcomes that can then be fed back to the real system to steer its course. DAFNI-ROSE will provide a platform for a federated national infrastructure digital twin, coupling diverse simulation models that will together contribute to digital twins that are national in scope.Infrastructure also affects a wide range of other areas, including the environment, where and how we live, our economy and our health. DAFNI-ROSE will develop collaborations across disciplines to explore the rich interaction between the built, human and natural environments.
