An improved GO methodology for system reliability analysis

GO Methodology is an exact method for system reliability calculation, but its existing quantification algorithms are all somewhat complicated for complex system. A new quantification algorithm based on matrix operation is introduced, which uses matrix to express the state probability of signal flow and operator, and obtains joint probability through probability matrix multiplication. State value of output signal can be got after simple classification in terms of operational rules of each operator. Quantitative formula of some operators is derived, and the analysis results of a power supply system show the new algorithm is effective and accurate.
