Safety evaluation of power plant based on cloud theory
Dong Chunyo · Journal of Liaoning Technical University · 2014
It is necessary to evaluate the safety of power plant in order to ensure its safe production. This paper measured and predicted the safety of power plant according to the uncertainty cloud theory, using the comprehensive evaluation method by applying system engineering. The evaluation index system was built according to scientific and representative principles while the expert judgment method was used to determine the weight, and the inverse normal cloud generator was taken to establish evaluation algorithm. Compared with other evaluation methods of level analysis, fuzzy comprehensive evaluation and principal component analysis, this method presents the safety evaluation index of power plant at the same time with a measure of fuzziness and randomness. Some specific examples are used to verify that this method is reliable, applicable, and provided a new theory and algorithm for the safety evaluation of power plant.
