Abstract: Some problems in the reliability analysis process of the multi-state system(MSS) are resolved. A new GO operator called multi-state operator is put forth to improve the accuracy and flexibility of GO methodology in building a reliability model for complex MSS. The joint state probability matrix and Boolean matrix are introduced, and then the operational rule and quantitative formula of the operator are given. The system reliability models of some water supply system and inertial navigation system (INS) are established based on the multi-state operator. Reliability analysis data were obtained through simulation. The results show that the multi-state operator is not sensitive to the state dimension of the unit and the complexity of the system in the process of reliability modeling, and also can better describe the complex logical relation between input and output.
