摘　　要：在基于CBM的装备保障中,备件订购是重要一环。针对带有状态监测系统的单部件系统,假设部件退化服从gamma过程,以总费用率最小为目标,建立了系统退化过程模型和订货费用模型,结合改进的费用率函数对最优备件订购时间进行了决策。通过案例分析对提出的模型方法进行了验证。结果表明,所建模型可以降低备件的总费用率。In equipment support based on CBM,the spare order is important.In this paper,in order to achieve the objectives of the least total cost rate,established system degradation model and spare ordering cost model,components degradation are assumed to be gamma process.Joint cost rate model with this degradation model made a decision on optimal spare ordering time for a single-unit system subject to condition monitoring. Then,verified the model proposed in this paper through the case analysis.Results show that the model can reduce total cost rate effectively.
