An Improved Abraham-Method for Generating Disjoint Sums

An algorithm, based on the Abraham-method, generates a disjoint-sum-form of the structure function. This algorithm contains two major improvements on the original method, and they considerably reduce the number of disjoint terms. The algorithm is more effective than the Abraham method with respect to the computation time for complex coherent systems. These statements are demonstrated by 2-terminal reliability analysis of example networks.
