Abstract:

hrough analyzing the warship equipment support mode at sea, based on the equipment structure and the spare parts replacement and repair capabilities, the spare parts demand is determined according to the spare parts failure rate. The spare parts not shortage probability of the system is taken as the optimization object, considering the constraints of spare parts cost and warehouse space, a spare parts allotment optimization model based on the margin analysis method is proposed. As the optimization example shown, by carrying warship shop replaceable units, under the constraints of spare parts cost and shop space, the readiness of the warship equipment can be improved significantly.
