Research on the Prefabricated Building Quality Evaluation System Based on Rough Set Theory

According to the index selection principle and the construction technology of the prefabricated construction, this paper divides the evaluation dimension of the construction quality of prefabricated construction, and preliminarily establishes evaluation index system. Based on rough set theory, we reduced the index, determined the weights and conducted comprehensive evaluation through the index importance analysis. Finally, the construction quality evaluation system of prefabricated building was established. The use of relevant norms as a discourse domain can reduce the impact of human factors and ensure the authoritative of the evaluation system. It is proved that the evaluation system is scientific and reasonable in the quality of prefabricated building by examples.
