Information entropy-based variable fuzzy sets model for the classification of rock mass stability
Wang Ming-wu · Journal of Hefei University of Technology · 2008
To ensure the rational design and safe operation of tunnel engineering and underground engineering projects,the exact classification of rock mass stability is of prime importance.Based on the information entropy theory and the variable fuzzy sets theory,a new entropy variable fuzzy classification model using a relative difference function is discussed in this paper.And a method for determining comprehensive weights of evaluation factors based on the information entropy weights and the expert experience weights is also investigated.The results of a practical example are compared with those by other methods,which shows that the proposed method is feasible,effective and more objective.
