摘要:建筑信息模型(BIM)，以其强大的建筑数字化能力，已经在建筑生命周期的越来越多的领域和流程得到应用。在建筑设计过程中，BIM模型需要经过多次的修改才能形成一份完善的项目设计方案，这些修改信息可以为方案的优化设计提供借鉴，但是Revit不能对这些中间状态的信息提供详细地记录和有效地跟踪。为了实现对模型修改过程的全程跟踪和提高BIM模型的修改效率，提出了一个基于事件监听机制的建筑信息模型的版本管理方案，研究表明利用这个版本管理方案可以有效地实现对模型各种版本的修改信息的跟踪，方便了建筑信息模型的管理；同时，版本管理方案采取合并操作信息的机制，对同一对象的冗余操作进行清除，缩短了模型从初始状态到目标状态的执行时间，起到比较明显的加速作用。

Abstract: The Building Information Modeling(BIM), possessing powerful architecture digitizing capability, has been increasingly applied in construction fields and processes during the life cycle.In the architecture designing process, the building information model should be modified several times before perfectly forming a complete project design scheme, and those modification information can provide references for the optimization of the design scheme.However, Revit can not provide detailed recordings or eligible traces of those intermediate state information.In order to achieve all-the-way tracking and improve efficiency of the model modifications, this paper presents a version management scheme of building information modeling based on event monitoring mechanism.Research shows that such a version management scheme can effectively track modification information of various model versions, which facilitates the management of building information modeling.Meanwhile, the version management scheme adopts the mechanism of merging operation information to clear the redundant operation of the same object, which shortens the execution time of the model from the initial state to the target state, and plays a significant role in acceleration.
