Abstract:

Spare parts planning for warship on expedition in periodic support strategy is the major topic of naval equipment support,but there is no effective solution to it. Spare parts support system and support process in the periodic support strategy for warship on expedition are analyzed. The definition and mathematical model of spare parts instantaneous backorders are proposed. The spare parts instantaneous backorders probability distribution model in the periodic support strategy for warship on expedition is established, according to the characteristics of selfsupport phase, periodic initial support phase and periodic circulation support phase. Finally, dynamic variety of warship instantaneous back orders of spare parts is reflected from the results of the model. The model would help military equipment support commander make support decision.
