An interdisciplinary Digital Twin Engine for science

interTwin共同设计并实现了跨学科数字孪生引擎（DTE）的原型，这是一个开源平台，为建模和仿真提供通用和定制的软件组件，以集成特定应用的数字孪生（dt）。它的规范和实现基于一个共同设计的概念模型——DTE蓝图体系结构——由开放标准和互操作性原则指导。其目标是制定一种适用于所有科学学科及其他学科的共同方法来实施直接临床试验，以促进发展和合作。协同设计涉及高能物理、射电天文学、天体粒子物理、气候研究和环境监测的DT用例，其复杂的需求预计将显著推进使用异构分布式数字基础设施、高级工作流程组成、实时数据管理和处理、模型的质量和不确定性跟踪、数据融合和分析的建模和仿真技术的现状。因此，支持研究的软件技术的整合将会出现。通过多个基础设施对该技术进行验证，将提高用户对技术能力的可及性，并支持人工智能在研究中的应用。interTwin建立在泛欧洲研究基础设施和科学长尾专家的能力之上，这是一个由技术提供商组成的开源社区，将提供TRL 6/7能力，以实现跨学科DTE，欧洲卓越中心的专家，以及来自EGI Federation， PRACE和EuroHPC的基础设施提供商，支持数据和计算密集型科学。interTwin关键可利用的结果将不断共同开发，并与外部倡议（如目的地地球、EOSC、EuroGEO和欧盟数据空间）的贡献保持一致。

interTwin co-designs and implements the prototype of an interdisciplinary Digital Twin Engine (DTE), an open source platform that provides generic and tailored software components for modelling and simulation to integrate application-specific Digital Twins (DTs). Its specifications and implementation are based on a co-designed conceptual model - the DTE blueprint architecture - guided by the principles of open standards and interoperability. The ambition is to develop a common approach to the implementation of DTs that is applicable across the whole spectrum of scientific disciplines and beyond to facilitate developments and collaboration. Co-design involves DT use casesfor High energy physics, Radio astronomy, Astroparticle physics, Climate research, and Environmental monitoring, whose complex requirements are expected to significantly advance the state of the art of modelling and simulation using heterogeneous distributed digital infrastructures, advanced workflow composition, real-time data management and processing, quality and uncertainty tracing of models, data fusion and analytics. As a result, a consolidation of software technologies supporting research will emerge. The validation of the technology with multiple infrastructure facilities, will boost the accessibility of users to technological capacity and the support of AI uptake in research. interTwin builds on the capacities of expertsfrom pan-European research infrastructures and the long tail ofscience, an open source community of technology providers that will deliver TRL 6/7 capabilities to implement the interdisciplinary DTE, experts of the European Centre of Excellence in Exascale Computing, and infrastructure providers from the EGI Federation, PRACE and EuroHPC supporting data and compute intensive science. interTwin key exploitable results will be continually co-developed and aligned with the contribution of external initiatives such as Destination Earth, EOSC, EuroGEO and EU data spaces.
