Research on the Key Techniques of the Virtual Construction

分析国内外研究现状,针对虚拟施工原型系统开发关键技术进行了研究。分析系统所应具备的功能模块及其相互关系,提出了虚拟施工原型系统软件体系结构;针对系统的智能特性,研究了面向智能体的施工建模方法;一般的施工数据库不具备知识发现和决策能力,提出了基于数据仓库、数据挖掘和OLAP技术的施工知识库构造方法及施工知识决策体系结构;基于多目标模糊优化决策理论解决了施工方案优选问题;先进虚拟现实软件开发平台EON具备功能完善、可视化编程界面、数据兼容性好等优点,提出了基于EON的虚拟施工原型系统开发技术路线。

We study the key and necessary techniques for developing a prototype system of the virtual construction.First,we analyze the function modules of the system and their mutual relationship.We propose the prototype system structure of the virtual construction.Then,according to the intellectual ability of the system,we specialize in the study of the agent oriented method for construction modeling.Because the common construction data-base is unable to discover knowledge and make a decision,we put forward a method for constructing a knowledge database and a knowledge decision-making system which is based on the data warehouse,data mining and OLAP（On-Line Analysis Processing） techniques.In addition,we solved the problem of construction scheme optimization based on the multi-objective fuzzy optimization and decision-making theory.EON is an advanced virtual reality software;it possesses the advantages of perfect function,visual programming interface and data compatibility.Finally,a prototype system of the virtual construction is developed,which is based on the EON.
