Abstract
ABSTRACT Monorail transit is a relatively small form of urban rail transit, having a considerable influence on city infrastructure; however, its quality evaluation needs to be further developed. This study aims to comprehensively evaluate the construction quality of monorail traffic, considering the newly completed Wuhu Monorail Transit Line 1 as an example. First, a comprehensive evaluation system comprising 5 dimensions, namely sustainability, social, economic, city development and technology, and 23 sub-indexes is constructed. Second, for scientific evaluation, the triangular fuzzy analytic hierarchy process is considered to determine the subjective weight of each index; then, the Critic method is used to determine the objective weight of each index. Finally, the game theory equilibrium weight method is used to determine the total weight of each index. Furthermore, considering randomness and fuzziness, the cloud model is used to evaluate the construction quality of the Wuhu monorail Line 1. The evaluation results show that the Wuhu Monorail Transit Line 1 has a high construction grade, with sustainability dimension A1, sub-index of greenhouse gas emission quality B11, and total energy consumption B12 during the construction period. The proposed evaluation method was verified using sensitivity analysis and has a strong practical value.
