数字孪生航道技术及成熟度等级评价模型研究

Technology and maturity level evaluation model of digital twin waterway

数字孪生航道是新一代信息技术与传统航道专业融合发展形成的一种新型航道基础设施。从数字孪生航道工程实际应用出发,阐述数字孪生航道的概念,构建包含物理实体航道、航道时空数据、孪生驱动引擎、数字虚体航道和场景应用服务在内的五维架构。根据数字空间到物理世界的逻辑关系提出以“仿真(L1)、映射(L2)、控制(L3)、预测(L4)和优化(L5)”为特点的五级数字孪生航道成熟度等级。基于五维架构和五级成熟度设计一套数字孪生航道成熟度评价模型,并在某段数字孪生航道开展定级评价,清晰展现其在数字孪生航道建设方面的长处和短板。结果表明,提出的数字孪生航道成熟度等级评价模型能有效指导数字孪生航道建设。

Digital twin waterway is a new type of waterway infrastructure formed by the integration and development of the new generation information technology and traditional waterway specialties.Based on the practical application of digital twin waterway engineering,we expound the concept of digital twin waterway,and build a five-dimensional architecture including physical entity waterway,spatiotemporal data,twin drive engine,virtual digital waterway and scene service application.According to the logical relationship between the digital space and the physical world,we propose a five-level digital twin channel maturity level characterized by“simulation(L1),mapping(L2),control(L3),prediction(L4)and optimization(L5)”.Based on the five-dimensional architecture and the five-level maturity level,we design a set of digital twin channel maturity evaluation model,and carry out the grading evaluation of a section of digital twin waterway,which can clearly show its strengths and weaknesses in the construction of the digital twin waterway.The results show that the digital twin waterway maturity level evaluation model proposed in this paper can effectively guide the construction of digital twin waterway.
