Abstract: The algorithm is based on constructing a disjoin㎏t set of the minimal paths in a network system. In this paper, cubic notation was used to describe the logic function of a network in a well-balanced state, and then the sharp-product operation was used to construct the disjoint minimal path set of the network. A computer program has been developed, and when combined with decomposition technology, the reliability of a general lifeline network can be effectively and automatically calculated.

Keywords: lifeline; network reliability; disjoint product; DFS algorithms; logic function; sharp-product
