国际金融中心与大城市群的协同性——兼论上海国际金融中心的建设

国际金融中心与大城市群的协同性表现十分明显。文章通过对拥有国际金融中心的英国、美国和日本的比较,发现它们都各拥有大城市群,同时伦敦、纽约和东京又分别是这三大城市群的核心城市,由此提出了国际金融中心与大城市群协同共进的观点,并在理论和实证上进行佐证。在现阶段,加快上海国际金融中心的建设离不开长三角城市群的支撑和促进,而后者也将最先受益于前者带来的金融资本等优势,大力促进长三角区域的金融一体化来加快长三角城市群的完善和成熟,对推进上海国际金融中心的建设进程意义重大。     

面向钢结构工程的BIM数据库平台设计

建筑信息化已经成为了建筑业发展的必然趋势,而钢结构作为建筑业未来的翘楚信息化进程更是势不可挡。依托BIM思想,建立面向钢结构的BIM数据库是客观需要也是必然选择;它的建立实现钢结构工程全生命周期的信息集成管理,实现了各个阶段信息的交互反馈,大大提高了钢结构的建造效率,降低了工程项目的成本。本文首先通过对钢结构工程和BIM模型简单介绍,具体分析了基于IFC标准的BIM模型的内容和结构框架,为基于IFC的BIM数据库的建立奠定基础;然后分类总结了钢结构的数据库内容,提出了基于IFC的钢结构BIM数据库的数据存储方法,最后得出了面向钢结构的BIM数据库设计的流程。     

结合IFC标准的建设项目中文文本分类研究

为促进项目参与方的合作和交流从而使项目更优质高效的完成,研究了结合IFC标准进行建设项目文档分类的方法。在对建设项目管理的特点进行深入分析的基础上,文章提出了将项目生命期中产生的大量的半结构化或非结构化的中文文本按照国际通用的IFC标准进行分类的方法,从而改进了文本的管理与利用效果。通过空间向量模型来表示中文文本,并采用夹角余弦的方法与国际通用的IFC标准中的实体进行相似度计算,最终实现中文文本的标准化分类,并通过案例分析验证了该方法的可行性。最后对本文提出的算法进行了评价,并提出了下一步的研究方向。

Development of process model for Serbian cadastre

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.
