摘要
针对地下工程数字孪生成熟度评价主观性问题,提出一种成熟度定量分级与评价模型.首先分析了数字孪生成熟度分级方法,提出了描述、映射、预测、控制与融合五级地下工程数字孪生成熟度分级.其次,建立了成熟度评价因子体系,基于决策试行与评价实验室法(DEMATEL)量化评价因子网络关系,提出了一种考虑标度一致性的网络分析法(ANP)模型构造与判断矩阵生成方法,并考虑了成熟度分级阈值限制,获得各因子的局部与全局权重.最后,结合某地下工程数字孪生实践验证了DEMATEL-ANP成熟度评价模型的可行性与有效性.
Abstract
This paper investigates the research progress of digital twin and proposes a novel digital twin concept framework for underground engineering.The digital twin maturity grading method is analyzed,and a five-level progressive developed digital twin maturity grading composed of description,reflection,prediction,control and fusion is proposed.Based on extensive literature research,a maturity impact factor system is developed,and a digital twin maturity evaluation model(DTMM)is proposed based on an optimized decision experimentation and evaluation laboratory(DEMATEL)and analytic network process(ANP)joint method for evaluating the degree of cause,centrality and dependency.Finally,the DTMM is applied in conjunction with an underground project,and the results proved that the method proposed in this paper is applicable to underground projects and has implications for the development of digital twin in underground engineering.
