Abstract: The membership calculation of evaluation indexes is easy to be ignored in the evaluation of solid construction waste recycling capacity, resulting in large evaluation errors. Therefore, this paper proposes an evaluation method of solid construction waste recycling capacity based on AHP-fuzzy algorithm. Determine the type of solid construction waste through different sources and properties; determine the index of solid construction waste recycling according to the type of solid waste, and calculate the weight of capacity index with the help of AHP; on this basis, the membership degree of the evaluation index is obtained with the help of the judgement matrix, the fuzzy evaluation subset is determined by the weight decision matrix, the AHP-fuzzy comprehensive evaluation model is constructed, and the solid construction waste recycling capacity index is input to complete the solid construction waste recycling capacity evaluation. The results show that the error of the proposed method is only 0.5%.
