Abstract: A new model for multi-state reliability analysis with considering common cause failure (CCF) which adapts an improved universal generating function (IUGF) method is proposed. The solutions of probabilities of all states of a multi-state non-repairable system are obtained by means of a 2-stage approach. In stage 1, system-output-performance distribution is described as IUGF without considering CCF; In stage 2, the contribution of CCF is correctly included based on CCF information of various common cause groups in system. An example is given to show availability and effectiveness of the method.
