Multistate-node acyclic networks reliability evaluation based on MC

A multistate-node acyclic network (MNAN) is a generalization of the tree-structured multistate-node system that does not satisfy the flow conservation law. The current known existing methods used to evaluate MNAN reliability are based on the minimal tree (MT) set. Instead of using the MT, an intuitive algorithm was developed in this to find the minimal cut (MC) set. The MNAN reliability can then be computed in terms of MCs. The proposed algorithm is simpler and more efficient compared to the best-known existing methods. The computational complexity of the proposed algorithm is analyzed and compared with the best-known existing methods. One example is used to show how all MCs are generated using the proposed algorithm. The corresponding reliabilities in this example are computed.
