Abstract: The escort formation consists of several ships and is a complex equipment system. The escort formation is taken as a research object, and the concept of phased mission system of systems (PMSoS) is proposed based on the phased mission system (PMS). A mission reliability model is established according to the characteristics of escort formation, and the phased fault tree is simplified according to the common failure basic task. On this basis, the binary decision diagram (BDD) modeling method is adopted to analyze the reliable events of each phase for the formation task, and the flow chart and detailed pseudo code implementation of BDD algorithm for solving the reliability to each stage are given. Finally, the reliability of escort mission process is analyzed and evaluated under the assumption that the life of escort formation system obeys the exponential distribution or the Weibull distribution, and the model and method proposed in this paper are verified.
