Abstract:

According to the shortage risk of spare parts of the warship formation, the concept of the warship formation support system is proposed, and the method of calculating the operational availability of the warship formation is given. After discussing the relationship among the three groups,  the mathematical model is established. In consideration of the differences of life distribution and the replacement time of parts,  many parts can continuously use after repairing and the limited repairable times when the warship executes the complex tasks in case,  the model of shortage risk of multi repairable spares and its relational model with the operational availability of the warship formation are established. Finally, the simulation example shows that the shortage risk of spare parts is reduced and the operational availability of warship equipment is improved.
