Reutilization value assessment approach for industrial building heritage based on hierarchical analysis process

The assessment of industrial building heritage reutilization value (AIHRV) aims to identify and quantify its cultural, economic, environmental and social values, to promote heritage conservation and sustainable development, and to enhance local characteristics and attractiveness. Therefore, this paper proposes an assessment of industrial heritage reutilization value based on the hierarchical analysis method by comprehensively considering eight indicators, including historical value, artistic value, cultural value, social value, scientific and technological value, economic value and environmental value, and 24 indicators, including sustainable value and historical era, cultural symbolism and public participation. Firstly, this paper puts forward the index system of AIHRV (including 8 first-level indices and 24 second-level indices). Secondly, it puts forward the method of AIHRV based on the hierarchical analysis method, including: establishment of the hierarchical standard of AIHRV, establishment of the hierarchical model of AIHRV, construction of the judgment matrix of AIHRV indices, square root method to calculate the maximum eigenvalue of judgment matrix, consistency test for hierarchical single ordering, and hierarchical total ordering, etc. Thirdly, the AIHRV level is obtained by combining the AIHRV level standard with the subjective scoring method and the objective weight assessment method. Finally, the correctness and validity of the proposed method are verified through a case study.
