The Application of Grey Relational Analysis Model in the Detection of Communication Interrupt in Self-Organizing Network

In the process of multi index analysis and evaluation, the index weight is determined according to each index relative principal component contribution through principal component analysis and principal component extraction. Then, combined evaluation model will be formed through the Grey Relational Analysis, calculation of each index according to grey weighted relative degree. Combined with key performance indexes in network communication, this paper establishes a break warming mechanism, thereby testing the scientific applicability of combinational evaluation model.
