Multidimensional measurement and comprehensive evaluation of regeneration value of old industrial structures from the perspective of stock renewal

The regeneration of old industrial structures is a new exploration of reuse and redevelopment of civil engineering in the stock era, it is very important to make clear the regeneration value of old industrial structures. Therefore, this study performed multidimensional measurement and comprehensive evaluation of the regeneration value of old industrial structures from the perspective of stock renewal. First, an index system for the regeneration value of old industrial structures was established from the perspective of stock renewal, including 5 first-level indicators (status quo, economic, social, ecological, and cultural values) and 27 s-level indicators. Second, improved Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) and entropy weight methods were introduced to construct a multidimensional measure and comprehensive evaluation model of the regeneration value of old industrial structures from the perspective of stock renewal. Finally, the reasonableness of the index system and the feasibility of the model were verified by analysing four projects. This study provides a basis for the regeneration decision-making of old industrial structures and a new idea and method for the analysis of the regeneration value of similar projects.
