Application of Improved AHP in Evaluation of Railway Emergency Plans

This paper establishes the comprehensive evaluation index system according to the features of railway emergency plans.The index system is characterized by complexity of the hierarchy structure and imbalance of index distribution.This paper analyzes these features and their impacts and errors caused to the traditional AHP.Accordingly,in order to reduce the adverse influence and errors,this paper improves the traditional AHP in construction of the hierarchy structure of indexes,and quotes the G1 Method in calculation of weighted values of indexes.Finally it gives an example of a Qingzang railway emergency plan to verify the rationality and reliability of the proposed method.And it points out the application scope of the method in other fields.
