Structure Analysis of Information Flow in Project Design Stage Based on Information Theory

Abstract To explore the importance of information in the project design stage, the uncertainty of information state of each link in the project design stage is analyzed through the information entropy analysis. And the difficulty of the obstacle encountered in each link is analyzed through the information distance theory. Then, the TBS method in product design is adopted to analyze the information state of the project architectural design stage. The result shows that when the demand information of the construction unit or the owner is fuzzy, more information needs to be processed in the design process. This leads to lower design efficiency and lower customer satisfaction with the result. This paper proves the importance of information in the project design stage from the perspective of information and provides the basis for the improvement of efficiency and customer satisfaction in the project design stage.
