树状建筑工程设计重用模型

A Hierarchical Data Model for Building Engineering Design Reuse

为了减少建筑工程单一项目内的设计信息的冗余数据,进而减少设计中的重复工作量,提出了"五层树状模型"来重组信息.该模型基于设计重用理论,充分考虑了建筑工程信息的构成特点,依据重用属性提取重用单元形成基本元素,借助五层树状结构实现数据重构以获得最终图纸,提高了数据的存储和利用效率.基于该模型开发的程序在重用单元的定义、搜索和组装等方面实现了自动化,满足实际工程大规模数据处理的需要,大幅缩短了设计周期.

To reduce the repeated work by avoiding from spawning redundant data for reduplicate design in building engineering, a five-layer data model is introduced to reorganize the design information. Based on design reuse theory and the constitution characteristic of the building engineering information, leaves in the hierarchical tree are abstracted from sheets of the blueprint according to reusable properties and are assembled back into sheets via the tree structure, which improves the efficiency of storage and data processing. With the model, a system is developed for defining, searching and assembling the reusable parts, which is suitable for large scale of data from practical project and shortens the period of design.
