Abstract:

With the continuous development of the international maritime satellite communication system (INMARSAT), the availability evaluation of satellite earth station (SES) is of great significance. Firstly, this paper constructs the reliability, maintainability and supportability(RMS) model to evaluate the availability of SES. Secondly, taking the equipment of SES as the research object, the equipment effectiveness probability is obtained according to Markov chain, and the system reliability is further deduced. Then, the queue-graphical evaluation and review technique(Q-GERT) network is established to describe the maintain and support process of SES equipment, and the modeling and simulation is carried out based on AnyLogic. Finally, through the application research of an example, the availability evaluation of SES based on the RMS model is obtained, which verifies the effectiveness and practicability of the proposed model and the evaluation method.

Key words: satellite earth station (SES), reliability, maintainability and supportability (RMS) model, Markov process, queue-graphical evaluation and review technique (Q-GERT) network, AnyLogic simulation
