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.
