Abstract: An algorithm of phased-mission system with multiple states is presented. The concepts of phased-mission system and its features are discussed, and an active standby (AS) tree structure method is proposed to depict the system structure of each phase. The behaviors of phased-mission system with multiple states are discussed based on state chart. According to discrete event simulation concept,a simulation algorithm is presented to estimate the reliability parameters of phased-mission system with multiple states. A case-study is introduced to verify the algorithm. The proposed simulation algorithm is very practical and versatile. The algorithm can be used to describe the complex behaviors of phased-mission system flexibly and obtain the more reliability parameters to understand the system operation. Key
