英文摘要：

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.
