Analysis on the instantaneous availability of series repairable systems in cyber warfare environment

Assessing the survivability of mission critical information systems is essential for combat capability analysis in the cyber warfare environments, and the instantaneous availability of system is one of the key indicators for information systems' survivability evaluation. In response to these problems, this paper formulates a network vehicle weapon system as a series repairable system. Then we investigate the probability of reliability and instantaneous availability under our proposed model. The simulation results show that maintenance ability and improved component repair rate are very important to system's reliability and instantaneous availability.
