Abstract—In engineering application, there are many systems whose mission often involves several different tasks or phases that must be accomplished in sequence. At the same time, some systems are composed of multistate components, which have different performance levels where one cannot formulate an "all or nothing" type of failure criterion. At first, the Multistate Fault Tree (MFT) is introduced to describe the multistate systems, then the method is put forward which can transform the MFT into Binary Decision Diagram (BDD). Secondly, a new algorithm is presented which combines the characters of multistate and multiphase and can obtain a single model of all phases. Finally, the case study shows that the method is available and can reduce the complexity of the PMS model.
Index Terms—Phased mission system, binary decision diagram, multistate fault tree.
