Abstract:
The paper applies the opposite and unity theorem of variable fuzzy sets to develop a dam safety evaluation model with the establishment of the evaluation index system of dam safety and its classification criterion based on the analysis of influence factors of dam safety and evaluation guide rules of dam safety. The model was used to analyze the engineering samples and the evaluation results were compared with those obtained from the set pair analysis method. The results showed that the both methods generate similar conclusions, but the evaluation method based on the opposite and unity theorem of variable fuzzy sets is clearer and easier for calculation, and therefore it is better than the set pair analysis method in evaluation of dam safety.
