Abstract
This paper evaluates the current status availability of old industrial areas from the perspective of sustainable development to provide a reference for decision making on the protection and regeneration of old industrial areas in China. In this context, we first analyzed and identified the factors affecting the current status availability of old industrial areas from the perspective of sustainable development, and established an evaluation index system that mainly includes the following four aspects: building availability, road availability, pipeline availability and environment availability. The unascertained measure theory was introduced to address the corresponding uncertainty problems associated with the current status of old industrial areas. To improve the reliability and accuracy of indicator weight calculations, a combined weighting method was introduced to determine the index weights. Based on the above foundation, we established an availability evaluation model for the current status of old industrial areas based on unascertained measure theory and the combined weighing method. Finally, old plant area projects were taken as case study examples. The evaluation results are generally consistent with the actual situation, which verifies the feasibility and rationality of the model. The research shows that the model is an organic combination of unascertained measure theory and combined weighting method, and is suitable for evaluating the availability of the current status of old industrial areas in China. It is hoped that a reasonable availability evaluation of the current status can provide a reliable decision-making basis for the protection and regeneration of old industrial areas
