Abstract:: In order to improve the accuracy of evaluation for single-layer industrial plant relocation and reinforcement based on fuzzy mathematics theory, the assessment was divided into three parts, including structural damage assessment, economic cost estimation and environmental protection. Twelve indexes were selected as evaluation factors, and the membership function method and analogy method were used to construct judgment matrix. Then the weight coefficient vector was determined by using analytic hierarchy process (AHP) method, and three-level twostage fuzzy comprehensive evaluation model was built. Taking the two single-layer plants of a company as examples, the technical and economical evaluations for industrial plant relocation and reinforcement were carried out. The results show that the evaluation result of fuzzy comprehensive evaluation method is objective, and can accurately reflect the advantages of single-layer industrial plant relocation and reinforcement. It can provide scientific references for the continual use and sustainable development of singlelayer industrial plant.
