The proposed approach for representing the fault trees uses data structures concept and dynamic storage allocation which overcomes the dimensionality problem. This approach reduces the computational complexity and execution time. This method can efficiently handle systems having any number of cut-sets between the input-output nodes depending upon the available computer memory. Three sample power system networks are considered to test the efficiency of the algorithm developed and the computation times with different approaches are compared.]]>Allan, R.N., R.
