摘 要：In this paper, we apply the theory of grey clustering evaluations and analytic hierarchy process to assess the interference of the circuit domain in GSM-R networks and make a comprehensive evaluation on interference. Based on the theory of grey clustering evaluations, the interference is sorted into rough groups. Then further classification of the interference can be obtained. The results show that grey clustering evaluations combined with analytic hierarchy process can provide the reliable interference evaluation in the railway services.
