Systems often operate in phased missions where their
reliability structure varies over a set of consecutive time periods,
known as phases. The reliability of a phased mission is defined as
the probability that all phases in the mission are completed without
failure. While the Binary Decision Diagram (BDD) method has
been shown to be the most efficient solution for measuring the reliability
of phased missions with non-repairable components with mutually
exclusive failure modes, the existing BDD based methods are
still unable to analyze large systems without considerable computational
expense. This paper introduces a new BDD based method
that is shown to provide improved efficiency and accuracy in the
repeat analysis of this type of phased mission.
