有效的数据互操作性和进度分析在提高装配式建筑的管理水平方面发挥着重要作用。然而，缺乏有效的策略和全面的方法，数据互操作性和基于数据的自动化进度分析。本文旨在通过建立一个基于IFC的框架来解决这两个问题，以促进装配式建筑的管理。首先，该框架提出了一种机制，建立一个基于IFC的装配式建筑的4D施工管理信息模型。并引入非关系型数据库--图数据库，将该模型映射为一个以任务为中心的网络，以实现不同参与者之间的信息互操作。最后，基于图形数据库的策略，以更新数据，自动分析施工进度和可视化的4D施工管理信息模型进行了描述。在一个预制工程案例中验证了所提出的框架。在此基础上，通过对IFC标准的扩展，建立了基于IFC和图形数据库的4D施工管理信息模型。基于图形数据库的模型分析自动识别工程实例的关键路径信息、延误分析信息和进度网络分析信息。实践表明，该框架能够成功地建立基于IFC的装配式建筑施工管理统一信息模型，实现有效的数据互操作。此外，应用此基于IFC的信息模型在图形数据库中可以自动分析施工进度，以防止可能的延误提前。总之，本文的意义在于创新性地提出了一种基于IFC和图形数据的信息模型，解决了装配式建筑施工管理中数据互操作性差、进度分析自动化程度低的难题。本研究可为进一步基于IFC的数字孪生模型奠定数字基础。
Effective data interoperability and schedule analysis play a significant role in improving the management of prefabricated buildings. However, there is a lack of efficient strategies and comprehensive approaches for data interoperability and data-based automated schedule analysis. This paper intends to promote prefabricated buildings’ management by solving these two problems via developing an IFC-based framework consisting of three parts. Firstly, this framework proposed a mechanism to establish an IFC-based 4D construction management information model of prefabricated buildings. Furthermore, a non-relational database—graph database—is introduced to twin this model into a task-centered network to realize the interoperation of construction information among different participants. Finally, graph database-based strategies to update data, automatically analyze construction schedules and visualize the 4D construction management information model are described. The proposed framework is validated in a prefabricated engineering case. In this case, an IFC-based and graph database-based 4D construction management information model is established through IFC standard’s extension. The graph database-based analysis of the model automatically recognizes the engineering case’s critical path information, delay analysis information, and schedule network analysis information. It is illustrated that this framework can successfully establish a unified IFC-based information model of prefabricated buildings’ construction management to prompt effective data interoperability. In addition, the application of this IFC-based information model in graph database can automatically analyze the construction schedules to prevent possible delays in advance. In short, the significance of this paper is to innovatively propose an IFC-based and graph data-based information model to solve the difficulties of ineffective data interoperation and unautomated schedule analysis in prefabricated buildings’ construction management. This study can be the digital foundation of further IFC-based digital twin.
