Comprehensive Evaluation on Power Grid Enterprise Operational Risk Based on TOPSIS Method and Grey Relational Degree
Jianhu Gong · Guangdong Electric Power · 2014
Aiming at existing risks in process of power grid enterprise operation,this paper introduces establishment of a set of operational risk management index system.On the basis of technique for order preference by similarity to an ideal solution,it introduces grey relational degree.By using entropy weight method,it confirms the index weight and by calculating, it acquires relational degree and relative closing degree between evaluated samples and ideal samples.According to the result,it is able to sort for important procedure of decision index and concludes that in process of power grid enterprise operation,risk degrees of different index are different.By examples,it verifies feasibility of this method.
