基于BIM的工程项目管理信息系统设计构想 总被引:3,自引:0,他引:3
在现代信息技术的影响下建设项目管理已逐渐转变为对项目信息的管理,传统的信息沟通方式已远远不能满足现代大中型工程项目建设的需要。文章从工程项目管理信息系统的研究及应用实践现状出发,总结了现阶段存在的问题,介绍了建筑信息模型(BIM)的概念、特点及应用前景,进而分析了基于BIM架构下工程项目管理信息系统的优势,提出了基于BIM的工程项目管理信息系统的架构及其九大功能模块,最后简介了该系统如何进行全寿命期的集成运行。 相似文献

高校图书馆由于人员密集、馆内藏书众多、设施材质易燃等特点,给火灾应急管理带来极大挑战.利用Revit构建图书馆BIM模型,运用Pyrosim软件建立FDS模型实现火灾场景模拟,分析火灾发生时各楼梯口处能见度、温度和CO浓度随时间的变化情况,得出各场景下疏散可用时间(ASET).然后,运用Pathfinder软件建立Agent-based模型模拟图书馆火灾应急人员疏散,得出应急疏散必需时间(RSET).最后,依据综合分析ASET与RSET的结果提出图书馆火灾疏散应急管理建议. 相似文献

Identifying the processes in the cadastre enables understanding the principles on which the cadastre works. Processes in cadastre define the way how the cadastre manages information and what are the prerequisites for the data to be stored in the appropriate data structure. In order to explicitly specify cadastral procedures and workflows to support their automatization, we developed a process model for Serbian cadastre. The main reason for developing the process model is to ensure the framework which will provide possible integration and interoperability with other systems outside traditional cadastral system and between cadastral subsystems themselves. The process model is based on hierarchical decomposition of two basic groups of processes: processes for changing cadastral data and processes for displaying cadastral data. Each group of processes is further decomposed step by step until the workflow of a single process is shown. The developed process model is an abstract model, i.e. it is independent of the implementation. However, in order to instantiate such process model, it is necessary to provide binding of the abstract process model to its underlying implementation. Cadastral registration of spatial units may be beneficial for activities that relay on land administration, such as taxation, spatial planning, obtaining a building permit or legalization of buildings. This relation to the processes under jurisdiction of other organizations justifies the use of cadastral process model and its implementation into SOA environment. Traditionally, cadastral processes include alphanumeric data and 2D spatial data on cadastral maps that contain 2D borders of parcels and buildings. However, recent advancements in 3D technology bring the opportunity to enhance such processes with 3D information. In particular, the aim is to extend current 2D process model to support data maintenance and transactions in the upgrade towards 3D cadastre. Therefore, these 3D data supported workflows are introduced to the process model. For the processes that include 3D information the choice has to be made which specifications will be used and how representations of 3D spatial units will be resolved. In this paper, we first develop an abstract process model of Serbian cadastre. After that, we extend the process model to include 3D information, discuss the options for using the encodings of 3D spatial units (legal spaces) and select buildingSMART openBIM IFC standard for this purpose. 相似文献

将运用BIM技术的建筑企业作为研究对象,以江浙沪及北京地区运用BIM技术的55个项目,其中涉及的92个建筑企业为例,运用社会网络分析方法,对建筑企业间的运用BIM技术合作网络结构进行整体网络凝聚性分析、中心性分析和小团体分析.研究结果表明,在建筑企业间的技术合作网络中的大多数企业可以通过中介成员与其他企业产生联系;BIM技术服务公司、建筑设计院的中心性相对较强;规模大的小团体较少,建筑企业的技术合作信息传递慢;建筑企业间的技术合作需要进一步加强. 相似文献
