摘　　要：在建筑信息模型(BIM)协同开发过程中,各参与方通常仅关注其领域相关的子模型数据而非复杂庞大的全局模型。为领域相关的子模型开发提供系统性的分布式开发功能,特别是版本控制支持,是BIM协同开发急需解决的问题。文章提出了一种基于BIM子模型的分布式版本控制框架,实现了分布式版本控制支持。建立了基于操作追踪的版本控制机制,通过记录用户对模型的操作,对操作序列进行叠加、逆反以实现版本跟踪;构建了相互耦合并独立工作的子模型层,不依赖于全局模型,实现设计人员在工作过程中对需求子模型的版本控制;构建了局部更新全局协同的工作模式,实现分布子模型与全局模型的版本协同。该系统已在开源BIMServer平台上实现,仿真结果表明,该系统在子模型支持、版本响应时间、存储资源占用及网络传输速度等方面均有明显的优势。In the process of the BIM collaborative development,different stakeholders usually only focus on their domain-specific data rather than the whole BIM model.Thus,it is important to provide a systematic distributed development function for the submodel development,especially for version control supporting.This paper proposes a distributed version control framework based on BIM submodel and achieves distributed version control support.Besides,version control mechanism based on operation tracing is established.The version tracing is implemented through superposition and reversion of operation sequence.The submodel layer which couples each other and works independently is established.Independent of global model,designer's control of submodel is achieved in the working process.The working mode of partial renewal and global collaboration is established to achieve version collaboration of distributed submodel and global model.The system has been implemented on the BIMServer-an open source platform.The simulation results show that,the system has obvious advantages in many aspects:submodel support,version response time,storage resource occupancy and network transmission.
