Research on the Extraction of Architectural Elements and Artificial Intelligent Aided Design of Tianjin Concession buildings Based on AHP-Fuzzy Comprehensive Evaluation --Taking the Upgrading of Tianjin HEPINGLU ZHAN Subway Station as an Example

This study adopts the AHP to construct a hierarchical analysis structure model of Tianjin Concession buildings, and builds an index system consisting of three primary indicators and nine secondary indicators for the value of Tianjin Concession buildings from the aspects of culture, history and architecture. On this basis, the Fuzzy comprehensive evaluation was applied to evaluate nine representative buildings of the former French Concession near HEPINGLU ZHAN Subway Station, and the final evaluation results showed that Quanye Department Store was the most representative building of the former French Concession. Subsequently, Midjourney, an artificial intelligence system, was used to generate the design scheme, which was processed by Photoshop software to finalize the subway station indoor environment design scheme.
