Notice of RetractionAssessment on Operational Risk of Power Grid Enterprises Based on Entropy Weight and Improved Grey Relation Analysis

The paper proposes the evaluation method on operational risk of power grid enterprises based on entropy weight and improved grey relation analysis. Firstly, it uses entropy weight to fix the weights of index system for the operational risk of power grid enterprises. Secondly, it determines grey weighted related degree of ideal object for each power grid enterprise, and then evaluates operational risk of each power grid enterprise. Finally, an example is used to prove the method is effective and practical.
