Research on system availability information model and analytical calculation method based on mission scenario

According to the complexity of system availability calculation model and the lack of system information in demonstration and early acquisition phase, system availability information model and calculation method based on system deployment and operational task scenario are proposed. This paper gives the concepts of static information model and dynamic information model of the system information model. The static information model and dynamic information model can simplify the availability information model. Basing on the support objects, support organizations, events and other factors in the static model, as well as along with the scenario and other factors in the dynamic model, this paper proposes a analytical model of calculation system operational availability and also gives out application case in the end.
