Study on Effectiveness Evaluation of Availability of Surface to Air Missile Weapon System

The evaluation of Availability is one of the most important ingredients of effectiveness evaluation of weapon system.Taking into account the operation condition of surface to air missile weapon system,the availability model of ground equipments was presented based on the availability theory of continuous working system,and the storage availability model of missile was presented based on the maintenance model of missile.The availability of each subsystem was integrated into the availability of weapon system based on the reliability block diagram of weapon system.The effect of the inspection period,the MTTR and storage availability of the missile on the availability of weapon system were discussed.The example illuminated that the model is reasonable and effective.
