Method of Safety Assessment about the Electric Power Supply Company Based on Cloud Gravity Center Theory

Since there are lots of qualitative indexes on safety assessment of the electric power supply company, the issue becomes exigent as how to transform qualitative descriptions to quantitative indication to make the safety assessment more scientific and accurate. Cloud theory which is based on traditional fuzzy set theory and probability theory consider the fuzziness and randomness, providing a powerful method for qualitative and quantitative information combining. This paper introduces Cloud gravity center evaluation in Cloud theory to safety assessment of the electric power supply company, which renders the reasonable transformation from qualitative concepts to quantitative descriptions. The case analysis shows the method is verified and scientific.
