Performance Evaluation of Optical Fiber Link in Power Communication Network Based on Cloud Model

Due to the uncertainty and ambiguity of security evaluation for power communication network, a security evaluation method based on structure entropy weight and cloud model is studied in this paper. Firstly, the index system is established for the optical fiber link in power communication network. Then the weights of index system are confirmed by structure entropy weight method which combines qualitative analysis and quantitative analysis. The security of communication network is evaluated by using cloud model and the final security performance are given. The method proposed fully considers the ambiguity of evaluation index and the simplicity of the calculation process, and there is not any restrictive calibration. The effectiveness of the method is verified by the evaluation examples of power optical fiber links in a certain area. The method is also suitable for other object from material, technology and management aspects.
