建筑工程投标报价辅助决策系统中的数据模型

Study on the Data Model for Computer Aided Construction Bid Decision System

根据投标报价的需要以及ＤＷ的基本思想，研究了建筑工程投标报价辅助决策系统的数据体系结构、主要操作型数据结构、分析型数据的主题结构，并给出了基于该模型的建筑工程投标报价辅助决策系统的应用．

Bid decision for construction needs many supporting information resources. Among the information resources, the data model is the basis of computer aided bid decision system, which affects the efficacy, efficiency and ability of the system in practice. Based on the characteristics of bid decision and DW (Data Warehouse), the data architecture for the system is firstly studied, and the structure of main operational data, as well as the structure on main topics of analytic data are discussed. An application of the proposed model for the construction bid decision of the Three Gorges Project is given at the end.
