Construction and application of synthetic safety assessment model for power plants
Lei Song · Computer Engineering and Applications Journal · 2010
A synthetic safety assessment model for power plant is constructed by combining Fuzzy Analytical Hierarchy Process(FAHP),Set Pair Analysis(SPA)and system functionality,in which the key factors influencing the power plants safety are con-sidered,and interaction among the factors influencing the power plants safety is analyzed quantitatively,a preponderant function of system safety is constructed by using of the result to solve the problem that the system safety function preponderates over the weight sum of safety functions of sub-systems.The instances show that the model can integrate immanence relation and non-lin-earity influence of factors in power plant,which make safety assessment more reasonably,and it can also offer scientific founda-tion for decision-making in safety management.
