Research on Protective Reuse of Industrial Heritage Based on Multi-Attribute Decision Making Method: Taking Six Heritage Sites in Qingdao as an Example

The integration and interaction between the protective reuse of industrial heritage and sustainable urban development has always been a concern and urgent solution for decision-makers such as the government and enterprises. From the perspective of multi-attribute decision-making, the application of the "PROMETHEE" theory can effectively assist in decision-making on the reuse of industrial heritage. Based on the PROMETHEE multicriteria and multi-attribute analysis theory, taking six industrial heritage sites in Qingdao as an example, a practical and feasible method for ranking and selecting strengths and weaknesses in industrial heritage reuse strategies was proposed by using various comprehensive analysis methods such as qualitative and quantitative analysis. This can provide theoretical basis for finding the most suitable reuse strategies and models for heritage sites, and provide a suitable practical method for solving the problem of high-quality reuse of industrial heritage. Research has found that it used to be difficult to determine the inheritance of reuse methods through empirical analysis, and data analysis using the PROMETHEE multi-criteria decision-making method can help make decision judgments. Among the six selected cases in the research institute, based on the PROMETHEE theory, the most suitable reuse strategies and methods were found for each of the six heritage sites.
