An interdisciplinary Digital Twin Engine for science

interTwin共同设计并实现了跨学科数字双胞胎引擎（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，以集成特定于应用的数字双胞胎（DT）。它的规范和实现基于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执行诊断技术的共同方法，以促进发展和合作。协同设计涉及高能物理、射电天文学、天体粒子物理学、气候研究和环境监测的DT用例，其复杂的要求预计将大大推进使用异构分布式数字基础设施的建模和仿真技术的发展，先进的工作流程组成，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。因此，将出现支持研究的软件技术的整合。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访问性，并支持研究中的人工智能吸收。interTwin建立在来自泛欧研究基础设施和科学长尾的专家的能力之上，这是一个开源的技术提供商社区，将提供TRL 6/7能力来实施跨学科DTE，欧洲Exascale计算卓越中心的专家，以及来自EGI联盟，PRACE和EuroHPC的基础设施提供商支持数据和计算密集型科学。interTwin的主要可开发成果将继续与外部倡议（如Destination Earth、EOSC、EuroGEO和欧盟数据空间）共同开发和调整。

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.
