An Extended ORESTE Approach for Evaluating Rockburst Risk under Uncertain Environments

Rockburst is a severe geological disaster accompanied with the violent ejection of rock debris, which greatly threatens safety underground workers and equipment. This study aims to propose novel multi-criteria decision-making (MCDM) approach for evaluating rockburst risk under uncertain environments. First, considering heterogeneity mass complexity environments, trapezoidal fuzzy numbers (TrFNs) are adopted express initial indicator information. Thereafter, superiority linguistic ratings experts modified entropy weights model TrFNs used calculate subjective objective weights, respectively. Then, comprehensive can be determined by integrating based on game theory. After that, organísation, rangement et synthèse de données relarionnelles (ORESTE) extended obtain evaluation results in circumstance. Finally, proposed applied assess Kaiyang phosphate mine. In addition, compared empirical methods other MCDM approaches. Results show that ORESTE reliable risk, provides an effective reference design prevention techniques.
